Study on the Similarity Between LOFT Decay Heat and LPWR Decay Heat

摘要

Two-time-step iradiation mode is proposed in the loss-of-coolant experiment (LOCE) at the Loss-of-Fluid Test (LOFT) facility for the accurate simulation of decay heat of fission products and actinide nuclides after 1-yr irradiation in a large pressurized water reactor (LPWR). Parametric calculations were performed to find out the best operation condition for each test in the L2 series and also to cope with the changes in the operating conditions. The cooling period up to 200 sec covers the anticipated reflooding phase for a LOCE. (ERA citation 04:030210)
