TEMPERATURE LIMITS FOR LMFBR FUEL CLADDING UNDER UPSET EMERGENCY OPERATING CONDITIONS

摘要

LMFBR fuel pin cladding tube is subjected to high transient temperatures during incidents such as pump trip, pump to grid plate pipe rupture etc. It is required to know temperature limits under such transient operating conditions for components involved while analysing such incidents. A methodology for deriving such limits for fuel clad tube is worked out in this paper by making use of the transient damage correlation proposed by W.F.Brizes et. al.
