Base Irradiation History and Interim Inspection of the BWR (Boiling Water Reactor) Test Fuel Rods of Rod Group BK7: The Studsvik Super-Ramp Project

摘要

Eight short BWR test fuel rods (rod group BK7) have been supplied by KWU for the Studsvik SUPER-RAMP Project. These fuel rods, assembled with six additional rods to two segmented rods of KWW standard length, were pre-irradiated in the nuclear power plant Wuergassen (Kernkraftwerk Wuergassen = KWW) Germany during four operation cycles from May 1975 to December 1980. After removal from the fuel assembly the rods were taken to the Hot Cells at Karlstein for interim inspection prior to the ramp tests at Studsvik. This report presents the detailed base irradiation history of the rods in KWW as well as the results of the interim inspection at Karlstein. 21 figs., 5 tabs.
