Japan's parliament passes bill allowing nuclear reactors to operate beyond current limit of 60 years

Tokyo [Japan], May 31 : Japan's parliament on Wednesday passed a bill that allows nuclear reactors in the country to be operated beyond the current limit of 60 years, Japan-based Kyodo News reported.
The move has been taken in order to help cut carbon emissions and ensure an adequate national energy supply despite lingering concerns over the safety of aging reactors.
According to Kyodo News, the law on power sources for green transformation and decarbonisation amends five laws associated with energy at once, including the electricity business law, under which the life span of reactors will be regulated.
As per some lawmakers and citizens, the bill was hastily passed without adequate deliberation, and public concerns about the safety of aging reactors were not properly addressed.
Japan's Economy, Trade and Industry Minister Yasutoshi Nishimura told reporters that the government will continue holding nationwide in-person or online briefing sessions to deepen public understanding of the law.
In Japan, fossil fuel-fired plants generate roughly 70 per cent of the nation's total electricity. The 2011, Fukushima nuclear crisis led to the closure of all nuclear reactors, with most reactors remaining offline as they must meet stricter safety standards introduced after the disaster in order to restart, according to Kyodo News.
Japan Prime Minister Fumio Kishida last summer said that the government will take the necessary steps to push ahead with the restart of more units, instructing the government to look into how the country can maximize its nuclear energy facilities most effectively.
The tougher safety standards under the reactor regulation law limit the service period of a nuclear reactor to 40 years, in principle, and up to 60 years if proper safety upgrades are made.
But under the new rules, nuclear reactors may be granted additional operating years in effect as their offline periods will not be counted against their total service time provided the periods are due to reasons beyond a utility's control, such as safety reviews needed for a restart and court-ordered suspensions.
The industry minister will give approval for extending the life of nuclear reactors on a case-by-case basis, Kyodo News reported.
