Technical exercise and demonstration of the spent fuel attribute tester at the TVO NPS in Finland. Final report on Task 416 of the Finnish support programme to IAEA Safeguards

Technical Report:

Abstract

A piece of new safeguards equipment, the Spent Fuel Attribute Tester (SFAT), is being developed for the verification of spent nuclear fuel in a standard storage geometry. Lifting of fuel assemblies from the storage position is not required for the verification. The SFAT can be handled like a fresh fuel assembly in the storage basin by the fuel handling machine. The feasibility of the SFAT-equipment for the verification of spent BWR fuel was demonstrated. A comparison of various types of gamma detectors, such as the Geiger-Mueller counter, NaI- and CdTe detectors was made for SFAT use. Measurements for optimizing the lead shielding, filtering, collimation and other geometrical parameters of SFAT were made. The precision of movements of the SFAT in the pond by the fuel handling machine and safety margins for these operations were estimated. (orig.).
