DNBR CALCULATION IN THE CASE OF DECREASE IN CORE COOLANT FLOW RATE

  • Four events could result in a decrease of core coolant flow rate. The DNBR distributions incore are calculated for these events, and the minimum DNBR is found out from theirdistributions. The results show that the lowest DNBR occurs in the event of the coolant pump ro-tor seizure, and the minimum DNBR of some of fuel elements in core falls below the limiting value1. 3.
