Talk:Sendai Nuclear Power Plant

Unsourced test claims
The article claims "According to the test, the reactors could withstand a seismic shock of 945 to 1,020 gals and tsunami-waves of a height of 13 to 15 meters." If these test reports are available in full to the public (translated into English if not already done) then they should be given as the source for this information. If the full test reports are not available to the public then this "according to" claim needs to be qualified as such. Wikipedia should not be put in the position of seeming to endorse the safety of Sendai in this way when it cannot back up such an endorsement with actual reports including all caveats etc. therein (i.e. not merely redacted, summarized, or paraphrased but faithfully translated).

According to a Special Bulletin released on July 17, 2014 by The Institute of Energy Economics, Japan, the 2011 tests referred to in the article were superseded by new stricter tests in June 2013. Sendai passed these new tests in March 2014, which were based on assumptions of 620 gal maximum shaking and 5 m maximum wave height, the latter being met with a 10 m wall (so presumably a safety factor of 2 for west-coast tsunamis, which would be too low for the east coasts of the four Japanese islands). Accordingly I've added the section Sendai_Nuclear_Power_Plant summarizing the main points of the Special Bulletin.

I've asked the Institute for the final report just now; if and when I get it and there's anything in it beyond what's in the Special Bulletin I'll update the section accordingly. For now the only information I can think of that's missing from the Bulletin is the seismic safety factor, i.e. how far over the 620 gal assumption the reactors tested at.

Meanwhile in response to my request for an updated report from the Institute of Energy Economics I received the following email dated 17 May 2016 16:23:48 +0900 (JST).


 * Dear Vaughan Pratt,
 * Thank you for your inquiry.
 * Unfortunatly, we do not updating this report about the Sendai Nuclear Power Plant.
 * Regards,
 * General Planning Group,
 * The Institute of Energy Economics, Japan

I interpret this as meaning that the July 17, 2014 Special Bulletin contains the most up to date information available to the public about the Sendai plant. Vaughan Pratt (talk) 06:50, 19 May 2016 (UTC)
