CNL provides information on a (non-radioactive) halocarbon release of 100 kg

(2016 July 29) 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.

CNL reports a loss of 100 kg of R-410a refrigerant from a building air conditioning unit. It was noted that the unit was not providing cooling for the building on 2016 July 26. Investigation into the cause identified that a copper line on the air conditioning unit failed resulting in the loss of 100 kg of R-410a refrigerant.  The air conditioning unit was repaired, tested for leaks, and returned to service. 

R-410a is non-ozone depleting, non-radioactive, non-flammable and poses no detrimental risk to human health. 

This release has been reported to Environment Canada as required by the Federal Halocarbon Regulations Act and the Canadian Nuclear Safety Commission was notified of the release as per CRL Site Licence requirements. 

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