The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Test to stop water leakage conducted in Fukushima

 

A research institute working on decommissioning the Fukushima Nuclear Power Plant has started testing a method to stop leakage of highly contaminated water.

Nuclear fuels in reactors No. 1 through No. 3 melted during the 2011accident. This caused highly contaminated water to flow into the containment vessels outside the reactors.

It’s believed the water is leaking inside the buildings through cracks in equipment that link the reactor with the containment vessel.

The International Research Institute for Nuclear Decommissioning is developing a method to fill the equipment with concrete.

The institute has started testing the new method at its facility in Naraha Town, Fukushima Prefecture.

Mock equipment containing water was set up in a building at the facility.

Concrete was poured into it through pipes and hoses.

The test is being remotely controlled, with the height of the accumulating concrete measured every 10 minutes.

About 200 cubic meters, or 4,800 tons of concrete will be infused over an 8-hour period.

Researchers at the institute say they will see if the concrete will solidify and stop the water leakage.

Prosecutors innocent TEPCO over radioactive water leakage into the ocean

The court said there is no evidence that proves that radioactive water flew out of the Fukushima nuclear power plant to the ocean. I hope this would finally convince those who haven’t been convinced that the state of Japan denies truth and violates peoples lives. Its time to get rid of Abe et al.

Prosecutors drop TEPCO case over radioactive water leakage

FUKUSHIMA–The Fukushima District Public Prosecutor’s Office announced on March 29 that it will not prosecute Tokyo Electric Power Co. or its executives for violating an environmental pollution law.

The decision came two and a half years after a group of plaintiffs, including residents of Fukushima Prefecture, filed a criminal complaint against TEPCO, operator of the crippled Fukushima No. 1 nuclear power plant, and its 32 current and former executives.

The group sought to bring charges against the utility and its executives for allowing radioactive contaminated water to be discharged into the sea.

In its decision, the prosecutors said there was “insufficient” evidence to press charges against TEPCO and some of its executives, including Naomi Hirose, company president. The remaining executives, the prosecutors said, “had no authority or responsibility to set measures to avoid the leakage in the first place,” therefore, the accusation has “no grounds.”

“The Fukushima police investigated the case for almost two years. It is extremely disappointing,” said Ruiko Muto, 62, the head of the plaintiff’s group, at a news conference in Tokyo on March 29. “We wanted them to look into the case further. We can’t accept this decision.”

The group is planning to appeal to the Committee for the Inquest of Prosecution. The group will meet with its lawyers on March 30 and decide on whether it will pursue further action.

Charges ruled out for Tepco figures over Fukushima No. 1 radioactive water spillage into sea

FUKUSHIMA – Public prosecutors decided on Tuesday not to indict Tokyo Electric Power Co. President Naomi Hirose and other current and former executives of the utility over radioactive water leaks from the crippled Fukushima No. 1 nuclear power plant into the ocean.

Sufficient evidence was not found, the Fukushima District Public Prosecutor’s Office said.

In September 2013, a civic group filed a criminal complaint against 32 current and former Tepco executives, including Hirose and Tsunehisa Katsumata, former chairman of the operator of the northeastern nuclear power plant, saying tainted water leaked from storage tanks into the ocean due to their failure to take preventive measures.

Through its investigation, the Fukushima Prefectural Police concluded that some 300 tons of stored radioactive water had flowed into the sea as of July 2013 because Tepco executives neglected to monitor the tanks or take leak-prevention measures, and sent the case to the prosecutors last October.

The prosecutors said there was no evidence supporting the allegation that the leaked tainted water was carried into the sea by groundwater at the plant, which suffered meltdowns following the massive earthquake and tsunami in March 2011.

The group said it will ask for a prosecution inquest panel’s investigation.
