Japan's industry ministry on Tuesday proposed extending the lifespan of nuclear reactors to beyond the current 60 years with ambitions to finalize the plan by the end of the year, in a bid to cut carbon emissions and ensure stable energy supplies threatened by Russia's war in Ukraine.

The Ministry of Economy, Trade and Industry is looking to extend the number of years nuclear power stations can remain open by considering screening periods, necessary for stricter plant safety operations, as separate from the total service life, which could allow nuclear reactors to operate for longer. During safety checks, the nuclear plants are not operational.

A ministry panel is set to discuss extending the service life of the nuclear power stations in such a way as a main scenario among other options, with plans to finalize their decision by the end of the year.
