Authorities say there is ‘no practical alternative’ Water storage tanks at the Fukushima-Daiichi nuclear power station site. IAEA/Dean Calma. Japan’s Nuclear Regulation Authority (NRA) has granted an initial approval for Tokyo Electric Power Company’s (Tepco) plan to release water from the destroyed Fukushima-Daiichi nuclear power station into sea, saying there are no safety issues.

The NRA plans to make a decision on final approval after a one-month public comment period, an NRA official was quoted as saying by local media.

In April 2021 Japan announced its policy to gradually discharge more than 1.25 million cubic metres of treated water into the sea, subject to approval from the NRA, an independent regulatory body.

It asked for the International Atomic Energy Agency’s assistance to help ensure the project’s implementation. Japanese authorities said there was no practical alternative to releasing the water as storage space ran out. They said there was no risk to human health and that operating nuclear plants around the world release similar water every day.

Purchase could give access to additional 6.9 million pounds of U308 Cameco will pay CAD107m to acquire the stake in Cigar Lake. Courtesy Cameco. Canadian uranium company Cameco and Orano group subsidiary Orano Canada have reached an agreement with Idemitsu Canada Resources to acquire its share in the world’s highest-grade uranium mine, Cigar Lake, in northern Saskatchewan, Canada.

Following the agreement, Cameco’s interest in the Cigar Lake Joint Venture company, which owns Cigar Lake, will increase by just over 4.5 percentage points to around 54.5%. Orano’s stake will increase by 3.3 percentage points to just over 40%. The remaining shareholder, Japan’s Tepco Resources, a Canada-based subsidiary of Tokyo Electric Power Company, will retain its 5% interest.

Cameco will pay approximately CAD107m ($82m, €78m) to acquire the stake in Cigar Lake from Idemitsu. This may be adjusted at the closing of the transaction, which is expected in the second quarter of 2022.

Authorities have identified next steps scheduled for 2023 Storage tanks at the Fukushima-Daiichi nuclear power station site in Japan. Courtesy Dean Calma/IAEA. Japan has made significant progress as it prepares to discharge treated water from the Fukushima-Daiichi nuclear power station into the ocean, the International Atomic Energy Agency said in its first report on the project.

The report summarises overall progress in the technical preparations for the water discharge. It compiles the initial findings from the IAEA task force’s first review mission to Japan’s Tokyo Electric Power Company (Tepco), operator of the Fukushima-Daiichi nuclear power station, and the Ministry of Economy, Trade and Industry (Meti) in February 2022.

IAEA director-general Rafael Grossi welcomed the initial findings and said the task force was satisfied that Tepco and Meti have identified the appropriate next steps for the water discharge scheduled for 2023. “The work will continue so the task force can provide its conclusions before the discharge,” Mr Grossi said.

The report is the first in a series of reports as the task force carries out more missions to Japan in the coming months and years to assess the water discharge against IAEA safety standards.

‘No environmental impact,’ says nuclear station owner The ice wall is intended to block groundwater from flowing into the reactor buildings. The owner and operator of Japan’s Fukushima-Daiichi nuclear power station said two storage tanks had leaked about four tonnes of coolant solution used to create an underground “ice wall” that prevents groundwater from seeping into reactor buildings.

Tokyo Electric Power Company (Tepco) said the leak had no impact on the wall or the environment.

The ice wall, in operation since 2017, is really more like a barrier of frozen soil. Built by Kajima Corp, it cost 34.5 billion yen ($303m) in public funds.

Tepco spokesperson Tsuyoshi Shiraishi said about four tonnes of the calcium chloride solution used to maintain the ice wall had leaked. “We’re now confirming the reason,” he said, according to the Japan Times.

A team of International Atomic Energy Agency (IAEA) officials are in Japan to officially launch a multi-year review of the planned release of treated water at the Fukushima Daiichi nuclear power plant. It is the IAEA's first mission as part of its review and monitoring assistance to support Japan before, during and after the discharge of treated water, which is expected to start in 2023.
