Instrument Development for Safeguards Implementation on Spent CANDU Fuels in Korea

Abstract

Korea is operating four CANDU reactors since the first in 1980 and is planning to have two more in the future. Safeguards implementation on CANDU reactors is complex and requires more safeguards efforts. Three safeguards instruments were developed recently to conduct national inspection on CANDU reactors. They are SCAV (Spent CANDU Fuel Verifier) for verifying spent fuel inventory in the storage pool, SCAI (Spent CANDU Fuel Bundle Serial Number Identifier) for reading serial number of spent fuel bundle in the pool, and SCAD (Spent CANDU Fuel Finger-Printer at Dry Storage) for dry storage inventory verification. These instruments were field tested, performed well, and are being used in inspection.
