Question
Consider the following statements in relations to the nuclear reactors and choose the correct alternative:
- The Pressurized Heavy Water Reactor (PHWR) uses natural Uranium as the Fuel.
- The Fast Breader Reactor (FBR) uses liquid Sodium as the moderator.
- The Advanced Heavy Water Reactor (AHWR) will be based on U233 as the Fuel.
- The French Company Areva is building the European Pressurized Reactors (EPR) at Jaitapur in Maharashtra.
Answer: Option A
Answer: (a)A fast reactor needs no moderator to slow down the neutrons at all, taking advantage of the fast neutrons producing a greater number of neutrons per fission than slow neutrons. For this reason ordinary liquid water, being a moderator as well as a neutron absorber, is an undesirable primary coolant for fast reactors.
