Order issued to Canadian Nuclear Laboratories Limited

Today, the Canadian Nuclear Safety Commission (CNSC) announced that it issued an order on July 7, 2017 to Canadian Nuclear Laboratories (CNL). The order was issued following a CNSC field inspection at the company’s Port Hope, Ontario location. The inspection occurred as a result of an event reported by the licensee indicating an uncontrolled release of untreated water from a collection pond on the Port Hope Project’s licensed site. The inspection identified deficiencies in CNL’s emergency preparedness for offsite releases and contingency planning for storing untreated water.

The order requires the licensee to ensure its emergency preparedness measures are available to mitigate accidental releases of untreated water from the licensed site. The licensee must also review its water management plans and program, to ensure adequate storage capacity is available to prevent the release of radiological and nuclear and/or hazardous substances from the licensed site.

The CNSC requires these measures to protect the health and safety of workers, the public and the environment.
