CNEA DONATES $240,000 TO NORTH FORGE EAST Consortium announces three-year funding commitment to local business incubator Last month, Canadian National Energy Alliance (CNEA), the consortium that operates CNL, announced that it will be donating $240,000 to North Forge East (NFE) to support economic development in Eastern Manitoba. The donation raises the total CNEA contributions made to NFE in recent years to nearly $650,000, funding that is being used to encourage entrepreneurship, business innovation, and commercialization in the region.

Joe McBrearty, CNL’s President and CEO, was joined by Blair Skinner, Mayor of Pinawa, John Gilbert, Head of the Whiteshell Closure Project, and Shane Li, President of North Forge East, for a cheque presentation ceremony to celebrate the donation. The funding will be allocated to NFE in the form of annual $80,000 payments delivered over the next three years.

“CNEA is excited to continue to support NFE programs and services, which have already made a meaningful difference in the lives of many local residents here in Pinawa and the surrounding communities,” commented Joe McBrearty on behalf of the CNEA Board of Directors.

“As the decommissioning of Whiteshell Laboratories progresses, CNEA has a responsibility to help bring economic opportunity to the region. NFE not only helps local residents start their own new businesses, but it also helps these companies grow and penetrate new markets, all of which can stimulate the local economy. We’re proud to be a partner in that work.”

North Forge is a non-profit organization that supports new business start-ups in the Province of Manitoba, and the NFE division was created to help incubate new businesses in the Pinawa region due to the Whiteshell closure project. According to NFE, the new funding will be used to support ongoing operational costs and to continue to help encourage economic growth and opportunity for the local economy by supporting local entrepreneurs who are working to establish and grow sustainable businesses.

“Over the past five years, CNEA has invested $400,000 towards NFE programs, which has helped to support 43 new start-up proposals, 30 of which continue to make strong progress with their business plans,” commented Jack Craig Jr., Chair of the CNEA Board of Directors. “And some of these start-ups are moving directly to Pinawa to launch their new companies, which creates employment and helps grow the local

economy, just as the program was designed to do. We hope to build on this success with this new three-year funding commitment.”

To date, participation in NFE’s programs have far surpassed the organization’s original estimates, and the incubator recognizes the important role that CNEA’s funding has played in that progress.

Blair Skinner, Mayor of the Local Government District of Pinawa and Board Member of NFE is also very appreciative of the ongoing support from CNEA and CNL. “CNEA has provided funding for North Forge East since its inception in 2016, which has enabled the NFE team to exceed our forecast for attracting entrepreneurs and encouraging people to move to Pinawa to start their businesses,” explained Skinner. “In addition, NFE President Shane Li has established a provincial pipeline for international entrepreneurs through the Manitoba Provincial Nominee Program, and a federal pathway through the Start Up Visa program. NFE is also a member of the National Angel Capital Organization and recently signed a Memorandum of Understanding with Futurpreneur Canada, which has already led to the referral of new clients to the region.”

“All of these opportunities were made possible by CNEA donations, and the community of Pinawa is very grateful for another threeyear funding commitment to maintain the momentum of this very important project, which helps to diversify the economy of Pinawa and our neighbouring municipalities,” added Skinner.

"SIC" NEW FUEL CLADDING FOR NUCLEAR REACTORS! Could silicon carbide be the perfect material for components such as fuel cladding?

Silicon carbide (SiC). It’s tough. It’s hard. It’s easy to manufacture. It is nearly invisible to neutrons. It is robust enough to contain fission products under immense pressures and temperatures. Could it be the perfect material for nuclear components such as fuel cladding?

Maybe, but this ‘great idea’ must undergo extensive testing first.

Enabled by AECL’s Federal Nuclear Science & Technology Work Plan, a team in the Advanced Reactors directorate has been undertaking a more thorough examination of silicon carbide to determine its suitability for use as a fuel sheath. Fuel sheathing (which encases the fuel) plays an important role within a reactor, balancing the fine line between being thin enough to enable efficient heat transfer to the coolant, but thick enough to maintain integrity during operation.

Most current generation reactors use zirconium alloys for their fuel sheath but lessons learned from the Fukushima-Daiichi earthquake and subsequent nuclear accident are highlighting the need for a better or more robust material.

“In the accident at Fukushima-Daiichi, the fuel within the reactor was without cooling for a period of days. During this time, as a result of the decay heat in the fuels, the fuel began to swell and the fuel sheath was split open, releasing fission products and fuel into the environment,” explains Liyan Qiu, R&D Scientist in the Advanced Reactor Materials and Chemistry Branch. “An additional complication, the 3.7m long fuels were clad in zirconium. When temperatures get high enough, zirconium interacts with steam to create hydrogen gas, which resulted in explosions at the site. The high temperature properties of SiC delays the onset of degradation, both oxidation and mechanical strength, to temperatures closer to the melting point of UO2 (2,865 degrees C) and therefore is well positioned to enhance reactor safety.”

In the new materials test loops within the Harriet Brooks Building (B350), Liyan and the team have been running a number of tests to examine the performance of silicon carbide under the conditions that exist within an operating reactor.

“SiC has excellent mechanical strength, high thermal conductivity, high hardness, and is resistant to irradiation, which makes it very

useful as a fuel cladding material. We created small coupons about 1 cm x 1 cm and placed them within our test loops. For 30 days they were exposed to irradiation, high temperature (~300 degrees C), pressures (10 MPa) and flow conditions in an alkaline solution that simulates the operating environment of nuclear reactors. This allows us to assess both the mechanical stability and the chemistry stability to see if there was any leaching into the coolant.”

The results of the testing are very promising. After their month long submersion, the pH and conductivity were almost stable. The measured carbon and silicon concentrations were near or below one ppm, suggesting that the released corrosion products from SiC are low, and there was very little weight change. These results suggest that SiC could be used for fuel cladding in water-cooled reactors, such as PWRs, BWRs, and PHWRs. A longer test (60 days) is under way.

“This work is aligned with a larger, global effort to develop 'Accident Tolerant Fuels' or ATF,” explains Lori Walters, Manager of Advanced Reactor Materials. “Just as the name implies, these next generation reactor fuels incorporate new materials, geometries and manufacturing processes to bring unprecedented levels of safety and efficiency. Within CNL’s Advanced Reactors Directorate, we are heavily involved in projects exploring many of these areas. This materials work leverages CNL core capabilities as a materials science lab to answer questions relevant to emerging technology.”

NSDF SAFETY CASE - YOUR 'GO-TO' RESOURCE Integrated written assessment demonstrates the safety of the NSDF projects In July 2021, CNL’s Environmental Impact Statement (EIS) for the proposed Near Surface Disposal Facility (NSDF) was accepted by the Canadian Nuclear Safety Commission (CNSC). While this marks a huge milestone for the project, many people hearing this news may still be unaware or further intrigued as to what the NSDF is, how it operates and where more information can be found. To answer all those questions and more, look no further than the NSDF Safety Case.

In short, the NSDF Safety Case is an integrated written assessment that shows a variety of arguments and evidence – spanning from CNL technical documents to external work from federal regulators and agencies, the public, local Indigenous communities and local municipalities – that demonstrate the short-term and long-term safety of the project and the meeting of all applicable regulatory requirements. The Safety Case covers all phases of the project, with documents within each section to carefully explain every aspect in specific and significant detail.

The NSDF is CNL’s proposal to build a disposal facility for all solid low-level radioactive waste at Chalk River Laboratories (CRL) to

of radioactive waste, and safety measures to protect both CNL employees and the public.

The concerns addressed throughout the Safety Case are a mix of the NSDF team’s own concerns with the project and the concerns of Indigenous Peoples, the public and regulators. The protection of the Ottawa River and other environmental concerns are two of the more important discussions CNL has had with the public during engagement and have been included in the Safety Case at length to help address those matters. Regardless of where they came from first, the arguments included in the document are there because of their fundamental value in demonstrating the overall safety of the facility.

CNL took pride in listening to multiple voices while developing the Safety Case to ensure that every concern of importance was touched on. Since 2016, CNL and members of the NSDF project have been actively reaching out to interested groups through site tours, public information sessions, community events, employee engagements, webinars, and more to create an open dialogue where all topics regarding the NSDF could be discussed. Over the years, the NSDF

The NSDF Project team

get one step closer to the company’s goals for revitalization and environmental clean-up. The details of this project and how it can be executed upholding the highest safety standards possible is a frequently visited conversation in the public eye. The NSDF Safety Case addresses all these concerns and more.

Among the abundance of information that can be found in the Safety Case, one of high interest to the public is the section dedicated to the integration of safety arguments. This section draws content from across the Safety Case and creates succinct arguments to show how the facility meets safety requirements. Some of these arguments include the protection of the Ottawa River, appropriate location for the facility, environmental sustainability, the reduction of environmental risks and liabilities, durability of long-term containment and isolation

team has determined most concerns stem along the same lines of a justification for the project, waste inventory, design and engineering details, long-term accountability, site selection, environmental effects, and the protection of the Ottawa River.

The Safety Case was submitted to the CNSC as part of the NSDF application process. The document has been through a rigorous review process – including third party reviews, one spearheaded by a United States government led expert panel with input from the United Kingdom nuclear industry as well – and all comments to date have been addressed. That’s not to say the Safety Case is closed. As with any project as large and with as many moving parts as NSDF is expected to be, the Safety Case will have to be revisited and updated as necessary through the duration of the project.

The monarch butterfly is one of a number of Species at Risk that CNL is working to protect at the NPD site

PROTECTING SPECIES AT RISK AT THE NPD SITE CNL works to safeguard key species at site of former NPD reactor CNL continues to make progress in the decommissioning of the Nuclear Power Demonstration (NPD) reactor. The NPD Closure Project is now in the midst of a federal environmental assessment, and CNL is committed to protecting the environment as part of the project.

One of the goals that CNL highlights with the NPD Closure Project is that, as a company, we’re committed to environmental protection and sustainable development. As Juliet Luiz, the Environmental Analyst supporting the NPD Closure Project, states: “CNL includes protection

of the environment and sustainable development as an integral component of our decision-making in all phases of our business activities. We are focusing our environmental efforts on reducing risk and taking responsibility. We don’t want to leave a burden for our children and grandchildren to deal with.”

At the biodiversity level, it’s essential to understand the site’s current environmental life to ensure that proper measures are put in place to safeguard key species now, and if CNL is granted the necessary

STUDENTS 'GATHER' FOR ANNUAL WORK EXHIBITION Since 2016, CNL Summer students have been invited to present the results of their research in a site-wide event as an opportunity to hone their presentation skills, learn from each other, and network with CNL staff.

If you haven’t attended in the past, you can likely imagine the large open space with students enthusiastically discussing their work beside their posters and attendees milling around listening to them.

Yet, COVID-19 - unfortunately and fortunately, made the organizers look at how to re-invent this exhibition in 2021 in a virtual format.

For anyone who has coordinated an event, worrying about human connection is just a matter of offering refreshments, but at present, making sure your online event has participants “Zoomed In” vs.

“Zoomed Out” tops the list.

Enter Gather, an online platform that makes the traditional online viewing and listening experience an interactive one, complete with designing unique spaces fit for the experience and customized avatars reminiscent of 20th century video games. So you could say

that this year’s exhibition came with a creative twist and our student participants did not disappoint.

“Our students were really excited with the format of this year’s exhibition,” said Mike Welland, Organizer and Research Scientist from the Computational Techniques Branch. “They work hard during their summer term at CNL, and the exhibition is a welcome opportunity for their achievements to be recognized. They appreciate the opportunity to discuss their work with attendees, receive feedback, and compete with one another.”

This year, the competitive element involved attendees being able to vote on each of the presentations – both the flash talks and the posters created by the students. In total, the “Gather” welcomed seven students and seven very interesting projects for staff to learn more about: •

approvals on the licensing and the environmental assessment, to move forward with the closure of the NPD site.

Chimney Swifts are one of the most well-known Species at Risk on the NPD site. They are a migratory bird species, often observed to arrive on-site in early May and begin to fly south in August. Video cameras have been installed to perform regular counts to ensure the data aligns with the SwiftWatch National Roost Monitoring Dates.

In addition, the ventilation fan is not operated when swifts are in the stack to ensure that the birds can enter the stack to roost or shelter from bad weather. Before initiating site closure activities, CNL must obtain a Species at Risk permit from Environment and Climate Change Canada and demonstrate that the NPD Closure Project will not negatively impact the swifts during project activities. As part of the permit conditions, CNL will schedule work to be done during daylight hours (when the swifts have left the stack), minimize dust and noise, and minimize activity close to the stack when swifts are using the stack.

Another species observed at the NPD site is bats, which potentially includes some Species at Risk bats, such as the Little Brown Myotis.

Bats have been observed hibernating in the facility crawl space since 2015. The location that these bats are hibernating in is not a sustainable place for them since the temperature drops below the ideal temperature range, which is between two degrees Celsius and ten degrees Celsius. CNL recently obtained a permit, allowing us to install a one-way door so that the bats can safely exit the building after the hibernation period and prevent the bats from returning.

During site closure activities, site sweeps will be undertaken to ensure that any bats found in the facility can be relocated before demolition.

The Monarch butterfly is another Species at Risk at the NPD site. This species depends on the milkweed plant to lay eggs, and once hatched, Monarch caterpillars only eat milkweed. There are several patches of milkweed at the NPD site, some of which are located in areas where there will be high levels of work activity during site closure (for instance, vehicle movement and mixing /pumping of grout in the batch plant). In order to prevent disturbance to the monarch butterfly the milkweed will be removed from these areas, but only between October 1 and April 30, when milkweed is not known to

• • • • • •

be used by any life stage of the Monarch. After site closure activities are complete, areas where milkweed was removed will be once again seeded with milkweed.

Finally, the Bald Eagle is known to nest at the NPD site. It is a Species at Risk listed provincially, and it also holds great cultural importance to Indigenous Peoples. Bald Eagles have strong fidelity to their nesting territories and many only have two or four alternate nests in one area. To ensure the Bald Eagle’s protection at NPD, a 400 metre buffer around the active nests will be implemented, as recommended by the Ontario Ministry of Natural Resources, to ensure no disturbance to the nesting birds occurs. The NPD Closure Project activities will remain more than 400 metre away from any potential nests ensuring the protection of the breeding pair and their young.

The NPD Closure Project isn’t only committed to ensuring the protection of Species at Risk but also a holistic approach to the protection of many more species found at the NPD site. A top priority for the project is to provide overall protection to the environment.

For example, CNL will ensure staff and contractors are trained on spill prevention to avoid harmful spills and response in case of an event; this will ensure that the environment remains a safe place for species to live. Additionally, the Migratory Birds Regulations prohibits the disturbance or harmful impacts to migratory birds or their nests.

For this reason, vegetation clearing is avoided between April 8 and August 31, the breeding period of most migratory birds known to be nesting in this area. Any staff sightings of wildlife on the NPD site are being recorded and identified by CNL biologists.

If necessary, additional mitigation measures are proposed and implemented as needed. CNL is committed to ensuring that Species at Risk observed on the NPD site are documented right away.

Environmental protection and monitoring will continue long after site closure activities are complete, to ensure all wildlife on site is protected and that our goals are aligned with our company’s visions.

The west side of Building 204 undergoes excavation

FD & ER TAKE ON THE BOWSER ROOM CNL team continues work on the Building 204 demolition project The Controlled Area at CRL is buzzing with construction activity, and one of the large excavations is in support of the Facilities Decommissioning and Environmental Remediation’s (FD & ER’s) Building 204 (B204) demolition project. As you walk by B204, you will notice barriers and detours. The purpose of the work is to expose the foundation of the building so that an opening can be made into the Bowser Room (fun fact: Nintendo’s Super Mario’s nemesis is named Bowser!) located in the basement of B204. The Bowser Room was used to filter rod bay water for the NRX reactor and as a result of historical operations, the room contains high radiological dose rates upwards from three Rem/hr. To put it into perspective, the annual dose limit for a New Energy Worker is five Rem. Although more time consuming to complete the waste removal from the exterior of the building, this method minimizes the accumulated radiation dose exposure to staff because remotely operated equipment will be used for entries into the room in place of manual labour.

service system line locates were completed through radar scans.

Following this, the west side of B204 was excavated to create a lay down area for two sea land containers that will be used during the waste removal phase of the project. The excavation was completed through hydrovac daylighting combined with hand digging. When an unexpected service line was discovered, all work was stopped and pictures of the lines were taken and sent to Engineers supporting the field work remotely for further analysis. After a thorough investigation to ensure that the line was isolated, hydrovac daylighting continued.

All of the removed soil was placed into large Pac Tec bags and will be disposed of as waste following characterization. A number of abandoned radioactive drain lines will need to be cut and capped in order to remove the sections of pipe within the excavation area.

To enable the removal of Systems, Services and Components (SSC) from the room, FD & ER’s Red Team will core an opening into the foundation of the building. The SSCs will be removed using Brokk robots. Weighing over 2,000 pounds, the Brokk is a remotely controlled robot capable of maneuvering around tight spaces and is equipped with grapples, a concrete hammer and nibblers. The concrete hammer will be used to core an opening into the exterior foundation wall. The grapples and nibblers will be used during the waste removal phase of the project; the grapples for loading, sorting and separating waste materials like pumps and piping, and the nibbler for cutting metal like the active storage tanks in the Bowser Room.

Temporary Ventilated Enclosures (TVEs) have been constructed and installed over the radioactive drain lines in preparation for their removal. The TVEs are in place as a measure for contamination control. When the abandoned drain lines are removed, concrete retaining walls will be used to support the soil and provide shielding from the radioactive fields being emitted from the Bowser room. An entry way will be cored into the foundation wall of the Bowser room with the Brokk robot. The TVEs will be dismantled, and two sea land containers will be maneuvered in front of the entry way and attached to the outside of the building, creating a temporary enclosure. One of the containers will serve as the anti-room and will house the Brokk robots; the other will be the control room where staff will remotely operate the Brokk robots. The anti-room will serve as the area where field staff will be able to don the appropriate Personal Protective Equipment and Clothing (PPE & C) required during the waste removal.

In order to safely accomplish this project, historical diagrams were researched, a Drilling, Digging & Coring permit was obtained and

The waste removal phase of the project will be separated into two stages. Stage one will be the removal of piping, pumps and conduit

waste and stage two will be the size reduction and removal of the former active storage tanks. All of the waste will be packaged in the B25s in accordance to the Waste Management Plan for the project, and transported to the Waste Management Areas for safe storage.

Following this, a barrier will be placed over the entry way and the sea land containers will be uninstalled and removed. The site will subsequently be cleared and the excavation area back filled.

The majority of the work will be completed during the summer months, and to mitigate the hazards of heat stress, an air conditioned break room trailer stocked with hydrating fluids has been placed in the vicinity of the work site. Additional field staff will also be scheduled to enable the work to continue while staff swap out for

breaks during periods of heat waves. Radiation Protection staff will support throughout the field work to mitigate the radiological hazards that the team will encounter during the radioactive drain line removal, and once the contaminate SSC waste is removed from the Bowser room.

The roadway on the west side of B204 will be closed for the duration of the project and detours are in place. If you are walking on the designated walkways during this time, please be extra cautious and vigilant as multiple pieces of heavy equipment will be operating. Work is expected to continue into the next few months, and is scheduled for completion in the fall.

WHAT'S HAPPENING IN BUILDINGS 412, 413 & 457?

Stores operations was moved from Building 457 to Building 1565 last year. The groups in Buildings 412 and 413 were moved to the new Support Facility, Building 750, in April of this year. The move, due to the large scale of equipment that needed to be moved, was a joint collaboration between the Capital Project team, the Site Operations team, Site Transition’s Post Operational Clean Out team, the Facilities Decommissioning and Environmental Remediation (FD & ER) team and the area owners. Buildings 412, 413 and 457 were transferred to FD & ER in May, and the project team has completed the following decommissioning work in the buildings: Building 412 The team is currently conducting a clean-up campaign in the building, removing any waste and items that remained following the move

INDIGENOUS ADVISORY COMMITTEE KICKS OFF CNL and AECL meet with Indigenous representatives for first committee meeting Representatives from Hollow Water First Nation, the Manitoba Metis Federation (MMF), Sagkeeng First Nation and Wabaseemoong Independent Nations, joined AECL and CNL leadership in the Whiteshell Building 300 conference room for the first Indigenous Advisory Committee meeting in mid-August.

The meeting was two years in the making, as in 2019, CNL proposed the establishment of an Indigenous Advisory Committee (IAC) to create a two-way communication channel with Indigenous communities for the Whiteshell Closure Project.

Elder Carl Fontaine from Sagkeeng First Nation opened the gathering with an Anishinaabe prayer. This was followed by greetings from AECL President & CEO, Fred Dermarkar, and CNL's Joe McBrearty.

This first IAC meeting created space for an exploratory discussion on what the key focus and objectives for this committee should be.

Participants engaged in a series of collaborative group methods to work towards a consensus.

Prior to the IAC meeting, CNL hosted Carl Fontaine from Sagkeeng First Nation and IAC facilitator, Jamie Dumont, for a tour of the WR-1 Reactor and the Waste Management Area on August 11. The tours provided an in-depth overview of the Whiteshell Laboratories site from CNL experts.

As there is a mutual desire to continue these discussions, work has begun to organize a second committee gathering in the fall.
