Japan mulls extending maximum nuclear reactor lifespan beyond 60 years
, KYODO NEWS – Jul 16, 2021 Japan is considering extending the maximum service period for its nuclear reactors beyond 60 years due to anticipated public opposition to the construction of new plants, sources close to the matter said Thursday.

The government is seeking to make long-term use of existing nuclear plants rather than building new ones or replacing reactors, as sought by the ruling Liberal Democratic Party and some business circles.

But such an extension could spur concerns about the safety of aging reactors that are prone to accidents.

………….The government plans to submit a bill to amend the law regulating nuclear reactors to the ordinary Diet session next year.

It will also discuss inspection and assessment methods to determine whether a reactor should be approved to operate for more than 60 years, referring to cases abroad such as in the United States where they can operate for up to 80 years.

In June, the No. 3 unit at Kansai Electric Power Co.’s Mihama plant in Fukui Prefecture, central Japan, became the country’s first reactor to operate beyond 40 years under the new rules.

According to government sources, a proposal has been floated to revise the law to allow multiple extensions beyond 60 years providing screening standards are met.

There are also calls within the LDP to exclude from the 40-year cap reactors that have been suspended since the Fukushima disaster.

Japan currently has 33 operable nuclear reactors, with another three under construction. But with several set to reach their 60-year maximum lifespan in the 2040s, only about 20 reactors are expected to still be in operation by 2050 under the current rules.

As part of the 2018 basic energy plan, which is being reviewed, the government is aiming for nuclear power to account for 20 to 22 percent of the country’s electricity generation in fiscal 2030 to meet its greenhouse gas emissions reduction goal.

The government estimates that about 30 reactors will be required to cover that level of power generation.
