Problem 3-4 Decay heat energy (section VIII) Using Eq. 3-70c, evaluate the energy generated in a 3000 MWth LWR after the reactor shuts down. The reactor operated for 1 year at the equivalent of 75% of total power. 1. Consider the following time periods after shutdown: a. 1 Hour b. 1 Day c. 1 Month 2. How would your answers be different if you had used Eq. 3-71 (i.e., would higher or lower values be calculated)?
