Mr. Doug Burton: In general, we also have on strategy to increase our business around the world, like Argentina, Romania, India and especially China which is most important to CFM. The next step in our product strategy is to manufacture simpler product, which is custom zircaloy tubes. Specially, we had two meetings with the State Nuclear Bao Ti Zirconium Industry Company (SNZ). The first was three years ago, and it was not successful. The second meeting we had maybe two weeks ago. I thought it was very productive, because we are also in a position to buy zircaloy. We also like to sell our zircaloy. So our in case, we make custom tubing, roughly 40 millimeters diameter, and smaller. But we buy 50 millimeter tubing. We are actually, I think, in a position to potentially buy some of our raw materials from SNZ, and then convert it to custom tubing which is interesting to buy something back, realizing they can make tubing as well, but that’s maybe an opportunity for us to provide some product to them. For our product portfolio, the custom tubing is very traditional, and we become very good at making small quantities of custom zirc tubing. There are very few people in the world can do that. There is another two product areas. The next one is all related HAF604 material for incore specialty components. We also have not just Cameco Fuel Manufacturing making fuel, but we also have Cameco Fuel Manufacturing making tubing, and we also have another division of Cameco Fuel Manufacturing making specialty in-core zircaloy related control system products that are in-core zircaloy related. That’s a very unique service and we have roughly 35 years of experience building these different components to top-level quality standards. That is specialty engineering, specialty manufacturing, The Chinese market is the largest growing nuclear market worldwide right now. There’s tremendous opportunity and I think there are a lot of qualified and extremely busy people working in China already.

highest quality because you can’t have a failure in this product. And finally we have one more small division that our engineers can custom engineer manufacturing equipment like we did in the Baotou Plant to make nuclear related products. So it’s really custom machine engineering and building services. Those are the three areas. Dynabond Powertech: Looking into the future, what’s your expectation in China? How much percentage do you want to get from Chinese nuclear market? Mr. Doug Burton: The Chinese market is the largest growing nuclear market worldwide right now. There’s tremendous opportunity and I think there are a lot of qualified and extremely busy people working in China already. The more we can help, the better we can help our friends in China business will follow. Cameco is a 100% nuclear company. We are a Canadian company dedicated to supply nuclear material and nuclear services. The subsidiary CFM still has the same policies, but really different products, much more specialized products. Our role is to fill in small niches, and that’s why we see opportunity in China because we are not looking for huge expansion, hundreds of millions of dollars of business. We are a niche supplier of custom product for nuclear focused on zircaloy related components. For CFM, China represents already perhaps 10% to 15% of our revenue. We have a good customer with long relationship and we are very happy to help them. When we have a niche product like we make to penetrate in Chinese nuclear market could take some time and we are committed to providing this service. It’s difficult to predict what growth will be for us in China from the base that we already have. We definitely see some opportunities to help with the niche product that we make. —End

Velan: Rooted in China and Close to Customers As one of the world’s largest valve supplier, Velan entered Chinese nuclear industry since 1990s. How does Velan maintain its sound name and reputation? What’s Velan’s strategy towards localization in China? What are Velan’s future goals in Chinese nuclear industry? Follow Dynabond Powertech Service (hereinafter referred to as DPS) on the interview with Mr. Michel MONIER, Corporate Director and Chief Representative Nuclear China Office, Velan.

the Group is around 500 million US dollars. Velan is a family owned company. Only 28% of shares are on the stock market in Canada. It’s a medium Mr. Michel MONIER: I’m 56 years old. I’ve been size, and steady company. In 1974, our French working in nuclear industry for over 30 years and company which at that time was not named Velan but had had 2 centuries of history was taken Velan is my first job in nuclear industry. I joined Velan in 1980. In the first ten years, I’ve been in over by Velan Group. I’m belonging to the French company. We joined Velan Group in 1974 the technical background. I was the Technical Manager at Velan in France. After, I’ve been the as a part of Alstom Group. It was a joint venture to develop the French nuclear market at that Marketing Manager for another ten years. I’m now in charge of nuclear business, especially fo- time, which is exactly the same situation we are facing now in China. Chinese governcus on Chinese nuclear power ment wants to create joint ventures to business. I’m also Chief Reprecope with nuclear industry. In 1974, we sentative in Nuclear China Office. have done the same in France. To sum up, I moved from technical to marketing development, Velan-France is specialized in nuclear and now the management of applications for Europe, Asia, and South business.

Velan Group has equipped DPS: Could you introduce us some of your background information?

DPS: What is Velan’s presence in international nuclear power industry?

350 among around 440 power plants that are in operation in the world. We have a significant market share.

Mr. Michel MONIER: Velan Group was founded in 1950 by Mr. A.K. Velan who is 94 years old now. He started the valve business by developing some smart devices. The group has around 1,800 staff with 15 plants in the world. We focus on valve for oil & gas, energy, mining, general services, and civil nuclear application, etc. The turnover of

DPS: The demand of a nuclear power plant for valves is huge, but the number of valve suppliers is also big. How does Velan maintain the competitive edge? Mr. Michel MONIER: Velan started with nuclear business in the U.S. and in Europe. The world’s very first nuclear power plants are using Velan valves. So we have a lot of experience. This is the 7


first point. Second, we always developed the right products. Velan has been focusing on new technologies, quality, and development. We use forged bodies, which means we took the raw material and use the press to deform it into one piece. With that, we grant our valves 60 years lifetime. Many other competitors use only the cast steel. We also developed low-maintenance valves. With such valves, you don’t need to care for maintenance in ten years after installation. We have brought a lot of different new things for valve and nuclear industry, some of which later became industrial standards. The third reason is qualification. 90% of our valves are used inside the nuclear building to cool the reactor, to spray water and to control the chemical of the water. We have done a great number of tests and reports to qualify such valves. Velan has more than 250 qualification reports, far more than others have. The fourth point is the feedback experience. Most of our valves have been operating for 20-30 years. We clearly know whether they are good or not according to our operational experience onsite. The fifth point is our company has the appropriate size to deal with nuclear program in China, France, USA and Europe. China planned to build 8 new plants per year before Fukushima, so you need suppliers that have enough financial capacity to buy materials and equipment. We have the right size to match the nuclear projects in China. The last point is we are very close to customer. China is a developing country for nuclear. We can help customer to improve. We provide technical support for customers. Besides, we explain to customers why our valves are good, unlike some other companies who just tell customers to buy. Also, we have a lot of experience to share with customers. DPS: When did Velan build the plant in Suzhou, Jiangsu province? What’s your strategy on this plant? Mr. Michel MONIER: This plant was built in 2009, 8


covering 6000 square meters with around 50-60 people inside. The machine in this plant is brand new and on the top of knowledge. We have welding robots. The plant started well. But so far we are not allowed to produce nuclear equipment in this plant because of Chinese regulation—the HAF601 requests that a new plant in China shall have five years of experience before producing nuclear equipment. We are using this plant as a subcontractor to manufacture components. In the future, we will produce more valves in China. But what is the good speed to implement that in a right time is a key decision for a group. It depends on the market, booming or decreasing. In fact Velan is moving step by step, but we don’t make big announcement and then do nothing as some other big companies are doing. Maybe it’s not a good way, but it’s our way.

workshop in France, which can produce valves for 10 nuclear power plant per year. The maximum we have made for China is at least 6-8 per year. If China restarts the program with the speed as before, we can handle it easily.

Mr. Michel MONIER: One nuclear power plant needs around 20,000 valves for nuclear island and conventional island. Among all these valves, safety related valves in nuclear island are around 200. This is what we supply. We focus on hightechnical-level, high-quality and difficult equipment. We don’t compete with domestic suppliers on the low-grade valves. Velan valves are used to avoid accident or control reactor after a major accident, such as Fukushima situation. This is why we need feedback experience. For Taishan, we supply more than 5000 valves. Taishan is European design so we have benefits of being close to the European designers.

find all raw materials, equipment or subcontractors we want because the knowledge of nuclear codes and standards is not so developed. We buy most of raw materials in Europe. Another issue is that the valves we’re supplying are not in so big quantities. It’s one by one, and big size. So far, Chinese valve makers want large production because this is the way in China. In Europe, especially in France, we understand that it’s our job to make small quantity, with very specific requirements, and a lot of agreements.

DPS: Do you like doing business in China? Do you have any difficulties with Chinese people?

Mr. Michel MONIER: Doing business in China is hard and challenging, and I like it. Chinese people want to learn and they listen to you. Older you are, better it is. In Europe it’s quite the opposite. Here, being old means experience. With foreigner, Chinese people are always with respect. Once you understand their behaviors, what to do and what not to do. Chinese people are so nice. Maybe it’s difficult for you to get confidence with Chinese people, but once you get it, you have it. DPS: Besides the HAF 601, did you encounter After, it depends on person.

team. Second, Velan has helped Chinese customers a lot in starting new plants. Chinese customer and Velan need to cooperate because there are so many plants to start. We also try to have regular exchange with professional organizations or associations. We have cooperated a lot. It’s a way of localization and a way to support self-reliance in China. Even you don’t manufacture valves in China, we are doing a lot to bring self-reliance in China for nuclear equipment. We try to make conferences, to meet people and share experience in Chinese industry.

clear programs, but not in a speed of building 6-8 nuclear power plants every year as planned. My understanding is 4-6 maximum. In fact, the future will have new reactors, ACPR 1000, CAP1400, etc. Today, these reactors are improved reactors, not yet available in the market. We need to wait till they will be approved by Nuclear Safety Authorities. It may take 2-3 years. In between, we will continue with improved CPR 1000. As such, new units AP1000 will not resume before 2-3 years because it is a brand new design. After Fukushima, nobody will start more reactors without the results of the first of kind.

We want to be close to customers to develop advanced reactors because the Fukushima occurred. We are doing our best to support improved design of Chinese nuclear reactor, even the design is good today. We have to consider what we have learned from Fukushima. This is a decision of Chinese government to do that also. We make us available to Chinese engineering companies to develop the new reactor regarding our equipment. We participated a lot in third generation nuclear power plants. We have signed contracts for EPR’s in Europe and gained good feedback. Our group is participating also in AP1000. We can bring something in terms of our equipment to develop advanced Chinese nuclear reactors such as ACP 1000, ACPR 1000, CAP1400, and some others. The idea is to share experience regarding third generation to help Chinese increase the safety level. Also, we will continue to focus on new projects and to prepare localization. DPS: What’s your opinion on Chinese nuclear power industry in the coming years? Mr. Michel MONIER: If you ask about my feeling, I’m quite sure that China is going to restart nu-

Topic of the month Problems found during the safety inspection of civilian nuclear power facilities Immediately after the Fukushima nuclear accident, the State Council conducted a nationwide inspection on nuclear power facilities. Recently, the NNSA released a report on the safety inspection of civilian nuclear power facilities (hereafter referred to as “the report”), seeking public opinions on China’s nuclear safety plans. The report firstly describes the present situation of China’s civilian nuclear facilities and reveals the inspection results. It highlights the problems found during the inspection and suggests corresponding solutions. China currently has 15 nuclear power units in operation, 26 under construction, 18 critical assemblies, and 9 civilian nuclear fuel cycle facilities.

plant’s design basis flood level should be 10.01 metres. It follows that the current flood protection measures are insufficient to cope with the aforesaid extreme situations. 3. Tsunami threat to China’s nuclear power plants Tsunamis have always been considered when selecting NPP sites in China. In fact, before the Fukushima disaster, based on the seismic parameters of China’s nearby sea areas and its submarine structures, the leading opinion in the academic circle was that coastal earthquakes or tsunamis should not be a major concern for China; rather, floods threatening the coastal plants were largely caused by storm surges.

In order to draw the necessary lessons from the Fukushima accident, the government during the nationwide inspection made a revaluation of the Manila Trench and Ryukyu Trench, the most likely ones to be the source of tidal waves affecting China’s nuclear plants. Preliminary results indicate that the Manila Trench is the more probFour major problems are raised in the report as able source of seismic surges.

The Ninth National Mining Academic Conference & Mining Technology and Equipment Show

Scientific article Study on the Impact of the Fukushima Accident on Nuclear Power Plant’s Site Selection in China On March 11, 2011, a magnitude 9.0 earthquake occurred in Japan, causing a severe tsunami which led to radioactive releases at Fukushima Dacchi Unit 1. Afterwards, all 6 units at Fukushima Dacchi encountered a sequence of different malfunctions including coolant loss, reactor overheating, over high pressure, fuel exposure and melting, hydrogen explosion, and radioactive release. The direct reason for the nuclear accident was the earthquake and subsequent tsunami. The earthquake shut down the reactor and disconnected the plant from outside power supply, while the tsunami destroyed the auxiliary diesel engine and disabled reactor afterheat discharging. On April 12, Japan's Nuclear & Industrial Safety Agency rated this nuclear leakage as the highest level—level 7.

The Ninth National Mining Academic Conference & Mining Technology and Equipment Show will be held on August 24th, 2012 at Kunming, Yunan. The Ninth National Mining Academic Conference is themed at “scientific innovation and sustainable development of China’s mining industry”. The conference is jointly organized by China Nuclear Society, China Coal Society, Geological Society of China, Chinese Society for Metals, Nonferrous Metals Society of China, Chemical Industry and Engineering Society of China, Chinese Ceramic Society, China Mining Association, and China Gold Association.

prone to earthquakes - 20% of the world’s earthquakes with magnitude 6 and above occur there. According to a survey, by the end of May, 2011, the Chinese mainland has 13 units in operation and many units under construction and planned (See Figure 2). Adjacent to Japan, China also locates between the circum-Pacific seismic belt and the AlpineHimalayan seismic belt. Since 1949, China has experienced more than 100 devastative earthquakes which destroyed over 300,000 square kilometers of land. China’s seismic activity is mainly distributed in 5 zones and 23 seismic belts (See Figure 3).

sign basis event occurred when Fukushima was chosen to be a NPP site. The accident alarmed Japan and its nuclear power industry. Shizuoka’s nuclear power plants were all shut down because the probability of magnitude 8.0 and above earthquakes in the middle of Japan is over 80% during the coming 30 years. In China, regarding the seismic investigation and safety evaluation in siting a nuclear power plant, the National Nuclear Safety Administration and State Seismology Bureau jointly issued in succession the 0 version and 1 version of nuclear safety guideline—HAD101/01, which is Earthquake Problems in Relation to Nuclear Power

From the above three figures we can conclude: ○1 The nuclear units in operation in mainland China are low in number and mainly distributed in Zhejiang, Jiangsu and Guangdong, these provinces hardly cover the seismic belt, whereas in Japan, the nuclear units are large in number and distributed along its lengthy coastline. The density of nuclear units in Japan is higher than that in China. Nuclear power plants in Japan cannot avoid the seismic belt. ○2 According to China’s political plan for the development of nuclear power, new nuclear power plants will shift to the inland area gradually and most of them will be concentrated in South China, far from the seismic zone. Comparing Figure 2 and Figure 3, we find nuclear power plants in Sichuan and Chongqing are close to the southwest seismic belt and that in Hongyanhe is close the northeast seismic belt.

1.2 Seismic survey and evaluation of potential sites According to a survey, the designed anti-seismic standard for early NPPs in Japan was magnitude 6.5, which was raised to magnitude 7.0 later by the Japanese government. TEPCO’s documents show that the hypothesis of an earthquake test on Fukushima NPP was only magnitude 7.9 at most. Therefore, the earthquake on March 11, 2011 was a beyond design basis event (BDBE). It can be deduced from the accident’s consequences that a double plan or a special design was not taken into consideration if a beyond de-

By the time a tsunami wave arrives at the Chinese sea area, its energy has been weakened due to the wide continental shelf and the frictional drag of the seabed. According to historical records, China has only witnessed 10 seismic sea waves - once per 200 years, since 2,000 years ago. Since 1949, there have only Figure 3 been 3 seismic waves recorded in detail, and none of them were destructive. So we can conits rescue and relief work.

Chinese nuclear safety regulations and codes have clear requirements regarding the possible impacts of tsunamis and floods when siting coastal nuclear power plants. HAF101 (Provisions on nuclear power plant’s site selection) requires that the possibility of a tsunami or a lake surge that could impact the safety of a nuclear power plant be assessed. If possible, historical information about tsunamis and lake surges in the proposed area should be collected. The impact of the data on the plant’s site should be identified. The height, frequency and size of tsunami occurrences and lake surges should be estimated according to historical information, and comparisons of such phenomena in similar areas should be made in detail. Factors that may intensify the natural phenomena caused by topography around the plant’s location should be taken into account to determine the design basis of tsunamis or lake surges. Moreover, nuclear safety code HAD101/09 (Determination of flood design basis in siting coastal nuclear power plants) points out: a plant should be located somewhere safe from the impact of a tsunami. If a power plant has to be constructed at a place which could be affected by a tsunami, its possible impact should be analyzed conservatively and the design basis of the flood is determined according to the maximum predicted tsunami. The design of a site elevation, jetty and revetment is determined by the design basis flood (DBF). The site elevation of a nuclear power plant should not be lower than the DBF and a safety margin should be taken into account. According to current regulations and codes, there is no specific requirement for the safety margin of a nuclear power plant, instead, the safety margin is taken from the regulations for thermal power plants.

River and an extra-strong typhoon happening concurrently. This is a good example for the future construction of nuclear power plants. Local special situations should be considered.

News of the month Highlights China’s nuclear industry in need of professionals According to industrial analysts, China’s nuclear power industry needs more professionals. A representative from a foreign nuclear power company indicated that the lack of nuclear professionals, especially those proficient in English, is holding up China’s NPP expansion. According to the statistics of State Administration of Science, Technology and Industry for National Defence, China will need about 13,000 professionals with a bachelor’s degree of nuclear science in 2020. A domestic expert also indicated that the domestic nuclear industry is in need of inter-disciplinary professionals not only proficient in technical skills but also familiar with global market rules and commercial laws.

ceeds would go towards five projects with a total investment of 173.5 billion yuan (HK$212.2 billion). The ministry said in a statement it had approved the IPO plan, which would also need the goahead from the securities regulator. China suspended approvals of new nuclear power plants in the wake of Japan’s nuclear crisis in March last year following a devastating tsunami, and ordered nationwide safety checks on existing plants and construction sites. The government has not made any decision on when to start approving new nuclear plant projects but the State Council, China’s Cabinet, last week approved a nuclear safety plan and said its nuclear power plants met the latest international safety standards. State media have said China will probably scale down its 2020 nuclear power generation capacity target to 60-70 gigawatts compared with earlier expectations of around 80 GW. China National Nuclear was formed last year as part of a restructuring of its state-owned parent China National Nuclear Corporation (CNNC). Chinese companies in industries such as nuclear, mining and chemicals must get approval from the environmental ministry before they can submit IPO applications to the China Securities Regulatory Commission (CSRC), the securities watchdog. If all or most of the planned projects are financed by share sale proceeds, China National Nuclear’s IPO could be mammoth, potentially surpassing Agricultural Bank of China’s the Hong KongShanghai dual listing could become China’s biggest. China National Nuclear owns the bulk of the nuclear business of CNNC, one of the largest companies owned by the Chinese central government. Source: http://www.scmp.com

EPR Reactor Vessel Installed at China’s first EPR reactor at Taishan power plant under the best conditions initiates an important new Taishan Unit 1 Nuclear Plant The construction of the EPR nuclear plant at Taishan in China, coordinated by EDF, CGNPC1 and AREVA, has passed a key stage in its development with the lowering of the reactor pressure vessel (RPV) into the Unit 1 reactor building, after which it was installed in its final location in the reactor pit. The positioning of this very large component weighing more than 420 tons, with a diameter of 5.3 meters and 10.6 meters high - marks the culmination of numerous civil engineering and assembly projects undertaken since the metal dome was placed on top of the reactor building at the end of October 2011. This important stage was coordinated by the project manager, Taishan Nuclear Power Joint Venture Company (TNPJVC: a joint venture owned at 70% by CGNPC1 and at 30 % by EDF), with technical support provided by local AREVA teams. David Emond, Taishan Project Manager at AREVA, stated: "The installation of the vessel for the

DPS:威兰给中国核电厂提供什么样的阀门?

井井有条,和西方公司风格相近。但是小公司做 事不够迅速,对核电项目也不够熟悉。

莫尼艾先生:一个核电厂需要大约20000个阀门, DPS:威兰本地化的策略是什么? 包括核岛和常规岛。在这些阀门当中,核与核安 全相关的阀门大概是200个,这些都属于我们的供 莫尼艾先生:首先,威兰不能找到所有想要的原 应范围。威兰注重高技术含量、高质量和高难度 的阀门,我们不和本地公司竞争低水平的阀门。 可以说,威兰的阀门是用来避免核事故的发生或 者发生事故之后控制反应堆,比如福岛核事故。 这也是我们需要反馈经验的原因。对于台山项目 来说,我们提供了5000多个阀门,因为台山项目 是欧洲设计,我们与欧洲设计商们关系很近。

2009年到2010年,威兰将法国工厂的生产能力提 升了一倍,每年生产10个核电厂所需的阀门。我 们为中国提供的最多的是每年6至8个核电厂所需 的阀门。如果中国重启核电项目,发展速度与之 前预期一样,我们也能够应付自如。

1 地震因素分析

我国与日本相邻,地处世界两大地震带——

1.1 中日核电站分布与地震带分布对比

环太平洋地震带和欧亚地震带之间。自1949年以 来,我国发生了一百余次破坏性地震,地震成灾

根据世界核工业联合会公布的数字,目前日本共 有运行中的核电机组55个,分布于狭长的海岸线 上,分布情况如图1所示。

面积达30多万平方公里。我国的地震活动主要分 布在五个地区的23条地震带上。其地震带分布如 图3所示。

图3 我国地震带分布情况 图1 日本核电机组分布示意图 通过图2与图3的比较,以及图1和日本位于环太平 日本位于亚欧板块和太平洋板块交界处,整个国

洋地震带的情况,我们可以看到:

家都地处于环太平洋地震带上,平均每年的有感 地震达1000次,世界上里氏6级及以上的地震大约 20%发生在日本,是世界上最易发生地震的国家 之一。根据调查,截止2011年5月中国大陆正在运 行中的核电机组总共有13座,还有许多建设中、 规划建设和前期工作中的核电机组,其分布范围 大致如图2所示。

①目前中国大陆正在运行中的核电机组数量较少 ,分别位于我国的浙江、江苏和广东三省,我国 在这些区域鲜有地震带分布。而日本核电机组数 量位于世界前列,散落分布于漫长的海岸线上, 分布密度远大于中国,并���各核电厂都无法完全 规避地震带。 ②随着我国核电的发展与国家的政策规划,核电 站开始向内陆发展,但可以发现建设与规划中的 核电站大多主要集中于华南各省,远离地震带的 区域。通过图2和图3比较,发现只有四川、重庆 处规划的核电站离西南地区地震带比较近,还有 辽宁红沿河离东北地区的地震带比较近。 ③我国幅员辽阔,从地震带分布图来看,以及自1 949年来历史地震成灾面积与整个国土面积相比,

图2 中国核电机组分布示意图

我国有广阔的地域可以规避地震灾害。 34


1.2 核电站厂址选择中的地震调查与评价

需要进行严格地地震调查与评价。要以福岛为鉴 ,重新审查和严格制定中国核电站抗震标准。

经过调查发现,日本早期的核电站,其设计抗震 标准为里氏6.5级。2006年,日本修改了核电站抗 另外,此次福岛第一核电站发生事故的同时,第 震标准,将最大抗震能力提高为里氏7.0级。据东

我国自1987年,关于核电站厂址的地震调查与安 全性评价,国家核安全局和国家地震局先后共同

2 海啸因素分析

发布了核安全导则HAD101/01《核电厂厂址选择 中的地震问题》0版本和1版本(国家核安全局,1 2.1 中日海啸情况比较 994)。核电站厂址选择中的地震评价,包括对所 选厂址的地表断裂、地震活动性、与地震和地质 现象有关的潜在永久性地面变形、海啸和湖涌等 厂址特征引起的地震安全性的评价,及抗震设计 所需的设计基准地震动参数的确定。在设计基准 地震动的确定中,每一个核电站厂址要确定两个 级别——SL-1和SL-2级的设计基准地震动。

日本的大陆架短小,且发育的很不好,都被许多 海底峡谷所切割。日本岛东部濒临广阔的西太平 洋,西部是深邃的日本海。日本海海底以海盆和 峡谷地形为主,多处水深大于3000米。日本东海 岸无其他岛链阻隔,直接面对广阔的太平洋。加

之日本恰好位于环太平洋地震带上,若地震震中 SL处于海底50km以内,并高于里氏6.5级,海底出现 1级地震动是对应于比较可能发生、破坏性不大的 大范围的上升或下降则会发生海啸,海啸又没有 地震荷载条件,称为运行安全地震动;SL宽广的大陆架阻隔削弱,因此,历史上日本曾多 2级地震动是对应于极限安全要求的,称为极限安 次遭受海啸的冲击破坏。 全地震动。

可以看出,两个级别设计基准地震动是十分必要 的。此次福岛事故说明,极限事故虽然发生概率 极小,但是其造成的破坏性极大。这也是对我国 的警示,对于运行中、建设中与规划中的核电站

与日本相比,我国海区处于宽广大陆架上,水深 较浅大都在200m以内。从地质构造上看,沿海地 区很少有大断裂层和断裂带,我国海区内也很少 有海沟,所以即使我国海区发生较强的地震,一 般不会引起海底地壳大面积的垂直升降变化。而 35

此次日本核事故还给我们一个警示,就是两个超 设计基准事故叠加的情况,比如这次的9级地震与 超级海啸。秦山核电站根据这个启示,考虑了特
