) The Sizewell B power station in Suffolk was opened in 1995 and may continue to operate for another 20 years. Its PWR reactor produces 1190 MW of electricity, and it normally uses uranium fuel enriched to 3.5% U-235. (i) If the reactor operates for 7300 hours per year, calculate its annual electricity generation in GWh. (1 mark) (ii) In such a PWR reactor a typical fuel burn-up of every tonne of enriched uranium fuel would produce 40 GW-days of nuclear heat. Express this in GW-hours of heat per tonne. (1 mark) (iii) The Sizewell B station has a thermal efficiency of 34%. Calculate how many GWh of electricity would be produced per tonne of enriched uranium fuel. (1
