(No, this is not an April Fool's Day's joke.)
Totally, absolutely in line with Prime Minister Noda's intention of seeking the "fourth way" for the future energy policy on reliance on nuclear power, the Nuclear and Industrial Safety Agency (which is still the one and only regulatory agency over the nuclear industry in Japan) is now considering installing a new safety standard:
You can continue to operate a nuclear reactor even if the reactor happens to sit on top of an active fault, as long as the expected size of dislocation is small enough.
This Kyodo News has the largest number of retweets I've seen on the websites of the Japanese mainstream media, currently with 9,015 retweets.
From Kyodo News (8/28/2012):
It was revealed on August 28 that the Nuclear and Industrial Safety Agency under the Ministry of Economy, Trade and Industry was considering the introduction of a new safety evaluation standard that would leave a possibility of continued operation of a nuclear reactor even when the reactor sits on top of a fault that could shift the ground, instead of uniformly banning the operation of such reactors.
So far, the NISA's opinion has been that "a nuclear reactor cannot be built on top of an active fault". Under the [proposed] new standard, it is expected that the continued operation will become possible for reactors that sit on top of certain faults which may be active faults, as long as the shifting of the ground is small enough and there is no effect on the reactor buildings.
There are many issues still to be resolved, as NISA admits that the method to precisely evaluate the size of the shifting is not yet perfect.
In the meantime, the prime minister who seeks the "fourth way" further elaborated on his stance. According to Jiji Tsushin (8/28/2012), Mr. Noda had a casual dinner in Tokyo with the DPJ's newbies (and apparently open to the press), where he told them and the press that he couldn't commit easily to "zero nuclear" because of national security concerns.
