Southern California Edison (SCE) installed monitoring instruments at Unit 3 at the 2,200 MW San Onofre Nuclear Generating Station in California to find a leak. It will take until the middle of next week before inspectors get a close look at a tube leak that prompted operators to shut down a nuclear plant on the California coast, […]
Fish taken from a lake in northern Vermont had similar levels of strontium-90 and cesium-137 as fish taken from the Connecticut River near Vermont Yankee nuclear power plant in Vernon. The fish taken from Lake Carmi were small-mouth bass and were taken from the lake by Vermont Fish and Wildlife fisheries personnel. Cesium was found […]

Rate payers and investors will need to decide if they want to […]
From the onset of the disaster through October 2011, TEPCO distributed around 17,500 potassium iodide tablets to about 2,000 workers on-site. According to TEPCO, the inventory at the plant held about 30,000 potassium iodide pills that were stored since March 13th of last year. All distribution of potassium iodide ceased at the end of October. […]
The Fukushima Daiichi Reactor 2 core spray system had been interrupted for 6 hours on 26 January in order to change a pump. Tepco says the way the water is flowing might have changed at that time, and might no longer reach the areas close to the fuel as well as before. Institute of Applied […]
Tepco said it increased the amount of injected water, some of which contained boric acid, at 4:24 a.m. Tuesday. Reactor 2 is now being cooled with 13.5 tons of water per hour, up from 10.5 tons. The boric acid is being used to prevent a sustained nuclear chain reaction, or recriticality. Tepco changed pipes and […]
