3.2.4 Generation III

 Various activities needed for implementation of the nuclear power

program ;  The agencies responsible for each of these activities;  Enabling measures like funding, for conducting the activities.

The government of Bangladesh adopted the National Nuclear Action Plan (BNPAP) for meeting the above-mentioned purposes for early implementation of the nuclear power project in the country in 2000.

Chapter 3: Technology of Nuclear Power

Nuclear power is the use of sustained nuclear fission to generate heat and electricity. Nuclear power plants provided about 5.7% of the world's energy and 13% of the world's electricity, in 2012.[35] In 2013, the IAEA report that there are 437 operational nuclear power reactors (although not all are producing electricity[36], in 31 countries. In addition, there are approximately 140 naval vessels using nuclear propulsion in operation, powered by some 180 reactors.[37]

There is an ongoing debate about the use of nuclear energy[38] Proponents, such as the World Nuclear Association, the IAEA and Environmentalists for Nuclear Energy contend that nuclear power is a sustainable energy source that reduces carbon emissions. Opponents, such as Greenpeace International and NIRS, believe that nuclear power poses many threats to people and the environment.[39]

Nuclear reactors are devices to initiate and control a sustained nuclear chain

reaction. Nuclear reactors are used at nuclear power plants for generating electricity and in propulsion of ships. Heat from nuclear fission is passed to a working fluid (water or gas), which runs through turbines. These either drive a ship's propellers or turn electrical generators. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of plutonium for weapons. Some are run only for research.

3.1 Fission/Fusion

In nuclear physics and nuclear chemistry, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and photons (in
