More Light Shed on Port of Halifax Transport Incident

CNSC staff conclude that the shipping container was improperly secured when being lifted off the vessel; yet stringent regulatory requirements adequately protected the public and the environment.

March 28, 2014

At a public meeting held on March 27, CNSC staff provided further clarifications on the March 13, 2014, incident at the Port of Halifax.

Their investigation concluded that the shipping container loaded with cylinders containing uranium hexafluoride (UF6) was not properly secured to a crane.

CNSC expert André Régimbald observed that the regulatory system worked as expected.

"The incident presented no risk to the workers, the public and the environment, and there were no breaches of the packages" said Régimbald.

Contrary to media reports, the radiation emitted from the packages remained at normal levels, at all times, and presented no danger.

"Everyone involved in the response took the correct, immediate actions, as per the CNSC's stringent requirements for emergency response" commented Régimbald.

The nuclear material originated from the UK, and was being shipped to a fuel fabrication company in South Carolina, to produce fuel for commercial nuclear reactors.

CNSC staff is completing their investigation, and will provide further details in writing to the Commission at a later date.

The cylinders were quickly stored in safe storage on March 15
Cylinders placed in new overpack on March 25
