Canada's Response to Fukushima
Updated November 25, 2014
On March 11, 2011, a magnitude 9.0 earthquake struck off the coast of Japan and caused a large tsunami, resulting in the loss of thousands of lives and half a million homes. It also caused an accident at TEPCO's Fukushima Daiichi nuclear power plant
Since then, the CNSC has established a four-year Action Plan to ensure that the lessons learned from the Fukushima accident are applied in Canada to enhance the safety of our nuclear facilities.
The CNSC continues to monitor activities that may have an impact on nuclear safety in Japan and remains alert to any activities that may impact nuclear safety. Information is also available through the International Atomic Energy Agency (IAEA) and Japan's Nuclear Regulatory Authority.
CNSC Integrated Action Plan
Shortly after the accident, the CNSC launched a review of all major nuclear facilities in Canada.
The review, led by a CNSC Task Force, confirmed that nuclear facilities in Canada are able to withstand and respond to credible external events, such as earthquakes.
In response to Task Force recommendations and following extensive consultation activities, the CNSC established an action plan to further strengthen the safety of nuclear power plants and other major nuclear facilities.
Actions related to both nuclear power plants and other major facilities are segmented in four categories:
- strengthening defence-in-depth
- enhancing emergency response
- improving the regulatory framework and processes
- enhancing international collaboration
The CNSC Integrated Action Plan also includes measures to enhance communication and public education.
Implementation and timeline
The Action Plan is being implemented in three phases based on management direction and public consultation:
- Short term (12 months) - for all actions that could be accelerated - these actions were completed by December 2012
- Medium term (24 months) - for all measures requiring further analysis and engineering design, or regulatory development most actions were completed by December 2013. Any outstanding actions were completed in 2014.
- Long term (48 months) - for all actions initiated in the previous periods that will require station retrofits and/or prolonged outages - to be completed by December 2015
For more details on the implementation of the Action Plan, please consult the Nuclear Power Industry Safety Performance Reports, which are published annually.
