A cryopump with pumping speed of 50,000 l/sec is planned to be installed in the Joint European Torus (JET) as part of the pumped divertor. The purpose of this pump is to control the plasma impurities. The pump consists of a helium panel cooled by supercritical helium and a nitrogen shield cooled by liquid nitrogen. This paper presents the following transient thermal flow analysis for this cryopump: (1) Consequences of loss of torus vacuum on helium panel. (2) Cool down of the nitrogen shield from 300 K to 80 K.
