Although no one outside the NRA seems to know clearly what is in the new safety standards that will be effective as of July 8, 2013, it has been praised by the media as the "world number one" and "world toughest".
So I looked for any write-up by the media about these standards, which should be of interest to many in Japan after the Fukushima nuclear accident. I couldn't find any beyond a mention of "filtered vents". So I went to the NRA website.
All they have is the drafts from February this year. As almost always happens in Japan and other "democratic" countries, the drafts were very likely to have been adopted as the official standards after public comments were solicited so that the government could claim the public had been consulted and then the comments were ignored.
From NRA's English page, "NRA Library":
- Overview Draft New Safety Standards for Nuclear Power Stations NRA, Japan（January 2013）【PDF：86KB】
- Outline of New Regulatory Requirements (Design Basis)【PDF：313KB】
- Outline of New Regulatory Requirements(Severe Accident Measures)【PDF：371KB】
- Outline of New Regulatory Requirements(Earthquakes and Tsunamis)【PDF：202KB】
Is there anyone who would care to read and highlight the points, problems for us? (I'm being too lazy, I know.)
If you prefer Japanese, here they are (in PDF):
I am skimming through the second one, "Severe Accident Measures". So far, many details on what facilities, equipment, manuals, measures to prepare in advance in case of a severe accident as defined by the NRA (core damage including core melt, containment vessel damage, spent fuel damage, and fuel damage while reactor is not in operation), but NRA seems to assume such facilities, equipment, manuals and measures will all work.
What if they don't work? Then what?
Or what if the next major accident is not BWR or PWR but fast breeder with liquid sodium as coolant?
Or what if the next accident happens at a plant not easily accessible like Fukushima I Nuclear Power Plant? KEPCO's Ooi Nuclear Power Plant is only accessible through a tunnel, and Mihama Nuclear Power Plant in Fukui Prefectureis is located on a peninsula connected to the mainland by a single bridge:
