In February 1987, Sandia National Laboratories (SNL), Albuquerque, and the Joint Research Centre (JRC) of the Commission of the European Communities, Ispra, Italy, started a joint development of a valid safeguards system using ultrasonic seals, to be fixed on MOX PWR fuel assemblies. Progress in studying a workable adaptation of the BWR VAK-III seal is reported. The difficulties inherent to the PWR fuel assembly design are reviewed and the use of associated items such as control rod clusters, whose motion into the assemblies must not be hampered, is considered. Prototypes have been built, indicating acceptable solutions for the case of fresh fuel seals. Seals have been reduced in size and one version has been studied with merged identity and integrity features, so as to be checked in a single operation. The compatibility with the fuel assemblies design requirements is also taken into account.
