Greenpeace: Takahama & Sendai reactors must be shut down immediately following Kobe Steel scandal

Tokyo, 1 December 2017 _ On 30 November, Kansai Electric and Kyushu Electric announced that they are delaying the restart of four nuclear reactors for approximately two months due to ongoing investigations into Kobe Steel components. Greenpeace is calling for the immediate shutdown of operating reactors, owned by these same utilities, that may also have defective Kobe Steel components at the Takahama and Sendai plants.
While Kansai Electric has delayed operation of Ohi 3 and 4 reactors, it continues to operate its two reactors at Takahama. Similarly, Kyushu Electric has delayed operation of Genkai 3 and 4, while continuing to operate its two reactors at Sendai.

“If Kansai Electric and Kyushu Electric are delaying restart of the Ohi and Genkai reactors due to the need to conduct investigations, how can they justify continued operation of the reactors at Takahama and Sendai? The NRA has so far failed in its responsibilities as a regulator to get to grips with this rapidly evolving scandal. It must set aside nuclear industry interests and prioritize inspections. That includes shutting down operating reactors that may have defective parts until and unless safety can be guaranteed.” said Kazue Suzuki, Energy Campaigner Greenpeace Japan.

More than a month ago, Greenpeace Japan warned that there were potentially major safety risks with Kobe Steel components installed in reactors that warranted strong intervention by the NRA.[1] On 24 October, Greenpeace Japan, along with other citizens groups, submitted evidence to the NRA of Kobe Steel’s extensive supply chain to the nuclear industry, demonstrating the pervasiveness of the potential problems.[2] We called on the agency to take urgent action to launch a comprehensive investigation into the supply and widespread use of potentially flawed Kobe Steel products in the Japanese nuclear industry. Included in the demands were calls for the suspension of restart plans for the Ohi, Genkai reactors, and shutdown of the four reactors Takahama and Sendai.

As of today, the NRA has yet to issue detailed written instructions to all reactor operators to investigate the use of potentially faulty Kobe Steel components. Instead, submissions have been made by 6 of the 11 nuclear utilities and lack any substantial information and analysis.

In one example, On 13 October, it was confirmed that Shinko Metal Products Co., owned by Kobe Steel, supplied tubes to the Tokyo Electric Power Company (TEPCO) for use in heat exchangers at the Fukushima Daini nuclear plant but failed to conduct required inspections.[3 & 4]
