Abstract

A flexible mathematical model has been developed in Part 1 to simulate the transient thermal response of a number of nuclear fusion components, including cryogenic devices that operate inside the JET Tokamak. The present work reports on the simulation of an accident scenario, as well as further studies of hypothetical off-normal scenarios concerning an out-of-vessel cryopump (the LHCD cryopump). These studies resulted in a complete safety protection system for the cryopump, which has been implemented into the JET operating routines.
