Reactor No.1 Stabilized as Fresh Water Injected, More Radiation Found in Ocean

Workers in protective gear try to restore electricity


TOKYO (majirox news) – Highly radioactive water was found inside the turbine buildings connected to reactor buildings No.1 and 2 at the Fukushima Dai-ichi power plant, according to Japan’s Nuclear and Industrial Safety Agency today. The water at reactor No. 3 contained 390,000 becquerels of radioactive materials, which is 10,000 times the normal level. The plant is 150 miles north of Tokyo.

“We’re trying to prevent a deterioration of the situation,” Prime Minister Naoto Kan said in Tokyo yesterday evening. “We must continue to work with a high sense of alertness. We cannot become complacent.”

The water that contains radiation is complicating the clean up, according to the safety agency. They have to figure out someway to contain this water. Work on restoring the water pumps will now be delayed.

Japan will switch to fresh water to help cool fuel rods as the salt in seawater causes corrosion of equipment at the nuclear plant. Hopefully, fresh water will be injected into the reactors and spent fuel pools at reactors No. 2, 3 and 4 tomorrow, instead of seawater currently used, according to the safety agency. Reactor No.1 is currently being injected with fresh water and has stabilized.

The agency said it doesn’t believe there is a physical crack in the pressure vessel or containment vessel at reactors No. 1, 2 and 3.

Radiation in ocean
Tests detected high levels of radiation in ocean water offshore, 300 meters from the plant, according to the safety agency yesterday. It was 1,250 times the government set-standards.

“Because the ocean current dilutes the radioactive substances, it will not pose a health threat,” the agency said today.

However, Mizuno, a nuclear expert at NHK, said if TECPO (Tokyo Electric Co., owner and operator of the plant) continues to pour reactive material into the ocean it will have an impact on ocean life.

According to TEPCO’s Web site, earlier seawater radiation monitoring detected levels of iodine-131 that were 126.7 times higher than government-set standards. Its monitors found cesium-134, which has a half-life of about two years, about 24.8 times higher than the government standards. Cesium-137 was detected to be 16.5 times higher than the standard.

Death toll and missing
The death toll rose to 10,102 with 17,053 people missing, according to the National Police Agency in Tokyo.
