A curve fit to the rate of the decay heat data of a typical
PWR fuel cycle resulted in the following equation:

Problem 55

A reactor that has been operating at nominal power level of
2700 MWth for 2 years is shut down. The decay power from this reactor, for any
time after shutdown, can be fairly well estimated from:

where t in this formula is the time after reactor
shutdown in seconds. Find a) the power obtained from the reactor 1 day after
shutdown, and b) the amount of energy produced by the decay power in a period
of 24 hours.
