2012 Update

In February, the Canadian Nuclear Safety Commission approved a five-year operating licence for the Port Hope conversion facility and a ten-year licence for CFM.

Labour relations

In July, unionized employees at our fuel manufacturing operations in Port Hope and Cobourg, Ontario voted to accept a new three-year collective agreement. The agreement includes a 5.25% wage increase over the term of the agreement.

In December, we received a positive decision from Canada’s Environment Minister to allow us to proceed with the licence amendment from the Canadian Nuclear Safety Commission, an amendment that is required to advance the project.

Springfields toll milling agreement

Based on the current market for UF6 conversion, we do not anticipate an extension of our toll conversion contract with SFL beyond 2016. We remain fully committed to the current contract. If market conditions improve over the next few years, we would consider resuming our discussions to extend the contract.

Planning For the Future


We have increased our production target for 2013 to between 15 million and 16 million kgU.

In 2013, we expect to commence the licence amendment process required for the project.

Managing Our Risks

Labour relations

The current collective agreements with unionized employees at the Port Hope Conversion facility will expire on June 30, 2013. Bargaining will begin in April 2013. There is risk to production if we are unable to reach an agreement and employees go on strike.

We also manage the risks listed here.
