Question
Transcribed Image Text:(a) Discuss the principal operational features of a modern (Generation-II) power-
producing nuclear reactor either of the pressurised water (PWR) or gas-cooled
(AGR) type, with particular emphasis en the fuel type and fuel enrichment, the
chain reaction, the neutron cycle, the choice and function of the moderating
material, the origin and role of delayed neutrons, the nature and function of the
control rods, and the nature and impact o: reactor poisoning.
(b) Advanced Gas Cooled Reactors (AGRS) operate at higher temperature than
Magnox reactors. Why does this require (i) different cladding; (ii) different form
of fuel; (iii) different enrichment of fuel, than a Magnox reactor?
(c) A fission reactor produces 3 x 10°W of electrical power. Assuming that the steam
generator has an efficiency of 30%, cal:ulate the mass of 23U consumed by the
reactor in one day. You may assume that the fission of one 23"U nucleus releases,
on average, 200 MeV of thermal energy.
