(a) Assume that in each fission of 235U, 200 MeV is released. Assuming that 5% of the energy is wasted in neutrinos, calculate the amount of 235 U burned which would be necessary to supply at 30% efficiency, the whole annual electricity consumption in Britain 50 × 10⁹ kWh (b) A thermal reactor contains 100 tons of natural uranium (density 19) and operates at a power of 100 MW (heat). Assuming that the thermal cross- section of 235 U is 550 barns and that the uranium contains 0.7 % of 235 U. Calculate the neutron flux near the centre of the reactor by neglecting neu- tron losses from the outside, and assuming flux constant through out the lattice. [University of Liverpool 1959]
