Japan's Kansai Electric to start survey to replace nuclear reactor
OSAKA (Kyodo) -- Kansai Electric Power Co. said Tuesday it plans to begin a geological survey to replace a nuclear reactor on the premises of its Mihama nuclear power plant on the Sea of Japan coast, in what would be the first new reactor since the 2011 Fukushima disaster. No new reactor construction has taken place since the building of the No. 3 unit at Hokkaido Electric Power Co.'s Tomari plant. The unit began operation in 2009.

IAEA publishes report on samples of treated water from Fukushima Daiichi plant
The International Atomic Energy Agency has released a new report on analysis of samples of treated and diluted water discharged into the ocean from the Fukushima Daiichi Nuclear Power Plant. It says the results are consistent with a 2023 report which "concluded that the discharge would have a negligible radiological impact on people and the environment." The IAEA published the latest report as part of additional monitoring measures that began last year. The number of locations for collecting samples was increased as part of the measures. The report covers a sample of seawater collected near the plant in October last year. It says experts from research institutions in China, South Korea and Switzerland took part in the analysis of the seawater collected near the plant. Japan's Foreign Ministry says missions for conducting the additional measures have been carried out three times so far, and that further survey results are expected to be published in due course. The ministry says Japan's government "will continue to maintain close coordination with the IAEA in sharing information with the international community in a highly transparent manner and fostering a better understanding of the safety of the discharge of ALPS treated water within both the domestic and international communities." ALPS is the Advanced Liquid Processing System, used to treat water that accumulates at the plant. Water used to cool molten fuel at the Fukushima plant has been mixing with rain and groundwater. The accumulated water is being treated to remove most radioactive substances, but still contains tritium. Before releasing the treated water into the ocean, the plant's operator dilutes it to reduce the tritium level to about one-seventh of the World Health Organization's guidance level for drinking water.

Japan's high court overturns earlier ruling in Fukushima Daiichi damages suit
The Tokyo High Court has overturned a lower court ruling and has dismissed a claim by plaintiffs for former Tokyo Electric Power Company executives to pay damages to the utility over the 2011 nuclear accident at the Fukushima Daiichi power plant. The ruling handed down on Friday does not hold the defendants liable. TEPCO shareholders had filed the lawsuit against five people who were in top managerial posts at the company at the time of the accident that followed a powerful quake and tsunami in March 2011. The plaintiffs said the accident occurred because of poor safety measures at the plant. They demanded that the defendants pay damages to TEPCO worth over 23 trillion yen, or about 160 billion dollars, to cover the costs the company incurred in compensating local residents who had to evacuate, decommissioning the plant and conducting decontamination efforts. Earlier in 2022, the Tokyo District Court ordered four of the defendants to pay the utility a total of 13.3 trillion yen, or about 92 billion dollars, in compensation. The amount of damages is believed to be the highest ever ordered by a court in Japan. Both the plaintiffs and the defendants appealed the ruling. At issue was a long-term assessment of possible seismic activities issued by a government panel in 2002. The lower court ruling said the assessment was found scientifically reliable. The presiding judge said the assessment made it obligatory for the company's managers to take measures against tsunami. The Tokyo High Court Presiding Judge Kino Toshikazu said on Friday that while the nuclear plant operator should have respected the assessment, it cannot necessarily be judged that the operator had been legally liable to take anti-tsunami measures.
