At Least 4 Nuke Plants Will Apply for Restart Under the New Safety Regulations to Be Implemented in July


If they are approved, there will be 8 additional reactors, including one with MOX fuel, will be online in Japan, in addition to two reactors at Ooi Nuclear Power Plant.

These plants are:

  1. Takahama Nuclear Power Plant: Reactor 3 (MOX), Reactor 4, operated by Kansai Electric Power Company;

  2. Ikata Nuclear Power Plant: Reactor 3, operated by Shikoku Electric Power Company;

  3. Sendai Nuclear Power Plant: Reactor 1, Reactor 2, operated by Kyushu Electric Power Company; and

  4. Tomari Nuclear Power Plant: Reactors 1, 2 and 3, operated by Hokkaido Electric Power Company.


Hokkaido Electric has postponed the plan to use MOX fuel for Reactor 3, but the plan is not abandoned. With local municipalities counting on MOX fuel subsidies to the tune of 6 billion yen, big money for these small municipalities, there will be a strong pressure for Hokkaido Electric, once the plant is back in operation, to pursue MOX fuel.

Shikoku Electric's Ikata Nuclear Power Plant sits near the tail end of the Median Tectonic Line, one of the biggest fault lines in Japan.

NHK News (5/28/2013) says the operators of these plants are going to apply anyway even though the plants may not satisfy the new safety regulations being compiled by the Nuclear Regulatory Authority.

Some of the problems that even NHK seems to recognize are:

津波対策の基準となる最大規模の津波や、新たに求められた火山について評価や安全対策を終えておらず「検討中」としていて、
Risk evaluation and the safety countermeasures for the maximum size of tsunami or for volcanic eruptions that will be newly required haven't been completed, they are "under consideration";

残る2か月足らずで安全性をどこまで確認できるのか具体的な見通しは立っていません。
How much safety can be ascertained in less than two months is not known;

新基準で義務づけられている、事故時の対策拠点となる「緊急時対策所」を別の施設で代用するケース
There are cases [NHK doesn't say which ones] where "emergency headquarters" as mandated by the new standard will be substituted by other facilities;

「防潮堤」を津波の想定が敷地の高さを下回っているので不要だとしているケース
There are cases where the operators says there is no need for "seawalls" because the expected height of tsunami is lower than the site elevation.


Uh... have we heard the last one before?

I think it is a clever ploy by the plant operators to apply at the same time for 4 plants with 9 total reactors, because the Nuclear Regulatory Authority lacks manpower to be able to assess the safety of each as they solidify the new safety regulations that are still evolving.

According to NHK, the operator of Tsuruga Nuclear Power Plant Reactor 2, Japan Atomic Power Company, says it will apply for the restart of that reactor anyway, even though the reactor has been declared by the Nuclear Regulatory Authority's panel of experts to be directly above the active fault line.

And there is TEPCO, who wants to restart Kashiwazaki-Kariwa Nuclear Power Plant with 7 reactors in Niigata Prefecture, even though they too may be sitting on the active fault line.

Fukushima happened, so we're safe for another decade or two at least. That must be the thinking.
