The non-fissile isotopes 238 U and 232 Th are converted to fissile isotopes of 239 Pu and 233 U, respectively, thus producing fresh fuel during reactor operation. The advantage with a breeder reactor is that it generates more fissile material than it consumes. B Has powerful moderator . A. Which of the following statement is true? The integral fast reactor (IFR, originally advanced liquid-metal reactor) is a design for a nuclear reactor using fast neutrons and no neutron moderator (a "fast" reactor).IFR would breed more fuel and is distinguished by a nuclear fuel cycle that uses reprocessing via electrorefining at the reactor site. Ans: c 35. Boiling water reactor uses the following as. Fast Breeder Reactor – Nuclear Power Plant Reactor Such reactors are designed to produce more fissile material (Plutonium) than they consume (Thorium Th-232). Which of the following statements is correct? A Acts as good moderator . B Lower . In contrast to most normal nuclear reactors, however, a fast reactor uses a coolant that is not an efficient moderator, such as liquid sodium, so its neutrons remain high-energy. 2. Like a traditional nuclear reactor a breeder reactor uses fission of nuclear materials to create energy. B Produces maximum steam . Take the Quiz for competitions and exams. The fast breeder reactor uses the following moderator (a) demineralised water (b) carbon dioxide (c) heavy water (d) graphite (e) no moderator is used. It uses Lead-cooled fast reactor.
