Canadian Nuclear Laboratories reports “incident” with spent fuel at Chalk River

(Chalk River, 2015 April 27) The following information bulletin is in accordance with Canadian Nuclear Laboratories (CNL) ongoing commitment to voluntary public disclosure of events related to the Chalk River Laboratories (CRL).

During the evening shift of April 19, CNL’s Rod Crew was loading a fuel basket containing spent NRX fuel bundles into a CRL-site transportation cask. The basket, weighing approximately 1,300 pounds is manipulated remotely with a crane; all basket handing operations are conducted within the rod bay and shielded beneath the surface of the rod bay water.

During loading operations, the crane grapple released the load before the basket was fully inserted into the cask, whereupon the basket descended to the pool floor. The cause of the unexpected grapple release is currently under investigation.

At the time of the event, all work in the rod bays was stopped and equipment was placed into a safe state. CNL management was made aware of the event immediately and CNL proactively reported the event to the Canadian Nuclear Safety Commission (CNSC) on the morning of April 20.

CNL confirms that there is no threat to workers, the public, the environment or nuclear safety related to this event.
