Question

A 1000 MWe nuclear reactor (5% U-235 fuel) has been operating at 100% power for 10 continuous days. On day 10, reactor power is brought down to 100MWe to load follow the power grid. After holding at 100MWe for 24 hours, the reactor starts to lose power. Despite additional removal of control rods, the reactor power continues to drop. a) What is causing the reactor to lose power? b) What steps can be done to correct this issue in the future?
