In a PWR (Generation 2) a large condensate tank can provide auxiliary cool-down for about 8 hours. If the Power plant is 1000 MWe and it has a storage tank of about 1000 m^3, by approximate calculations, please confirm that the requirements of feed-water are satisfied.

Solution

Heat generated within PWR (2nd generation ) will be lesser than the heat generated out of 1000 MWe reactor. If the auxillary cooldown could support the system for 8 hours, then(implies), steady state conditions are achieved at 5.5-6.5 bar. While considering a 1000 MWe, the steady state conditions cannot be achieved below 7.6 bar,implies, the 1000 m³ storage tank cannot satify the requirements.
