Safety vulnerabilities i Russia’s nuclear power plants

Working Document: Bellona’s Analysis of Post-Fukushima Stress Tests on Russian Nuclear Power Plants  March 3, 2014 by Bellona ST. PETERSBURG – After the disaster at Japan’s  Fukushima-Daiichi nuclear power plant  in 2011, nuclear experts worldwide agreed to stress-test their own reactors and called for the evaluation of European nuclear power plants in terms of their capability to withstand natural disasters and technical and human-error snafus.  Russian nuclear power stations were also subjected to safety assessments, the results of which Bellona’s Russian offices have analyzed in a working document devoted to the subject……..Bellona’s analysis shows that Russia has formally followed the international community’s recommendations on re-assessing safety issues surrounding atomic energy.  However, the report does not include enough expert information about all possible nuclear safety risks.  For example, the report states that Russian nuclear power plants are, on the whole, earthquake resistant, but additional measures must be taken in order to improve some components of auxiliary equipment safety.

At the same time, the report fails to outline any plans for investigating the earthquake resistance of the buildings, structures, and equipment of spent fuel storage pools.  Moreover, the report does not provide any test results on the potential effects of earthquakes paired simultaneously with other natural disasters, such as severe flooding…….

Stress tests on Russian atomic power plants also showed that all units under operation need to be equipped with additional emergency water delivery systems; these systems are essential in the case of interrupted cooling to the reactor core, storage pools, and nuclear waste depositories.  The bottom line is that before the Fukushima accident Russian power plants were often not equipped with such systems, or they were absent entirely.

Serious questions remain as to whether or not the vulnerabilities in nuclear power plant safety exposed by experts will be corrected in practice, and only time will tell whether or not the world will come to completely grasp Fukushima’s lessons.  For more detailed information on the Russian atomic power plant stress tests, you can read Bellona’s working document (in Russian). http://bellona.org/news/nuclear-issues/nuclear-meltdown-in-japan/2014-03-working-document-bellonas-analysis-post-fukushima-stress-tests-russian-nuclear-power-plants
