Water decontamination pump stops working at Fukushima

Tokyo Electric Power Co. (TEPCO) workers suspended a second test run of a water decontamination pump June 20 after it stopped working at the Fukushima Daiichi nuclear power plant, according to news reports.

The system designed to decontaminate highly radioactive water stopped five hours into full operation June 17, the article said. TEPCO officials said the pump was overburdened by excessive liquid flow and that equipment needed changing more frequently than previously estimated, NHK reported.

Storage facilities for contaminated water at the plant are reaching capacity and three of the plant’s six reactors have been overheating and leaking radioactive material.

The operator also said June 20 that a plant worker was found to have been exposed to radiation above the official limit, bringing the number of over-exposed workers to nine, according to the Kyodo Times.
