New Ultrasonic Sealing Systems for CANDU Spent Fuel Bundles
A new sealing system for CANDU reactor spent fuel bundles, to replace the AECL ARC seal, was developed, according to the IAEA requirements.
The new bolt for underwater sealing is derived from the design of the sealing bolts already used in the La Hague reprocessing plant. The design was revisited in order to comply with the CANDU interface requirements.
A first series of 15 bolts, with the new reading head and data acquisition system, was produced. Field trials began in June 2006 at Cernavoda NPP (Romania).
A second series of 50 bolts and one reading head was built for the Vulnerability Assessment to be done by an independent laboratory.
This paper discusses the design of this sealing system and the initial results of both field trials.
