Public Safety Canada Update - 6:00 p.m.: "Damaged Japanese Nuclear Power Plants not Expected to Pose Risk to Canada" - The Government of Canada is actively monitoring the situation and assessing the potential risks to Canada as a result of the damage to power plants in Japan. The situation in Japan is not expected to pose any health or safety risk to Canada. Federal departments and agencies are closely working together and are in close contact with the International Atomic Energy Agency, the Government of Japan and the international community to manage the current situation.
Please note that there does not appear to be any damage to the primary containment vessel of either reactor as a result of the explosions.
The Tokyo Electric Power Company (TEPCO) continues its efforts to cool the reactors in Units 1 and 3 through the injection of sea water and boron. Similarly, Fukushima Dai-ichi Unit 2 is experiencing cooling system problems and TEPCO, the Japanese operator, is preparing to inject sea water into the reactor.
It should be noted that the automatic shut-down systems on these reactors worked as designed when the earthquake struck, however, the following tsunami damaged the primary and back-up power systems for the reactors, which resulted in the failure of the reactor cooling pumps.
Japanese authorities are reporting to the IAEA on the status of their nuclear power plants. To read more, please visit the IAEA Web site.
The CNSC continues to monitor the situation in collaboration with the Department of Foreign Affairs and International Trade and other federal counterparts and is in constant communication with the IAEA International Seismic Safety Centre, the Organisation for Economic Co-operation and Development Nuclear Energy Agency, and the U.S. Nuclear Regulatory Commission.
The CNSC, as the Canadian nuclear regulator, is confident about the safety of Canada?s fleet of nuclear reactors regarding seismic activity. The CNSC would like to reassure Canadians that nuclear power plants located in Canada are among the most robust designs in the world and have redundant safety systems to prevent damage in the case of an earthquake. The CNSC sets requirements and verifies that its licensees meet those requirements. All licensees must have effective emergency procedures in place which are regularly tested through drills and exercises, and can manage potential consequences so that workers, the public and the environment are protected.

CNSC Update - 4:15 p.m.: The situation at Fukushima Dai-ichi Nuclear Power Station continues to evolve. On Saturday, March 12th, a build up of hydrogen gas resulted in an explosion at Fukushima Dai-ichi Unit 1. On March 14th, a similar explosion occurred at Fukushima Dai-ichi Unit 3. In both cases, the build up of hydrogen resulted from venting of vapor from the primary containment vessel into the secondary containment building.
Please note that there does not appear to be any damage to the primary containment vessel of either reactor as a result of the explosions.
