Tepco Reports Another Radioactive Water Leak at Fukushima Plant –‘The site had plastic pipes to transfer radioactive water.’
“Tepco has about 100,000 tons of highly radioactive water accumulated in basements at the Fukushima Dai-Ichi nuclear station.
“On April 5 Tokyo Electric Power Co. said as much as 12 tons of radioactive water leaked from a pipe at its crippled Fukushima nuclear station, the second such incident in 11 days at the same pipeline, raising further doubts about the stability of the plant.
“Part of the water may have poured into the sea through a drainage ditch, Osamu Yokokura, a spokesman for the utility, said by phone. “There will be similar leaks until Tepco improves equipment,” said Kazuhiko Kudo, a research professor of nuclear engineering at Kyushu University, who visited the plant twice last year as a member of a panel under the Nuclear and Industry Safety Agency.
Perhaps only another major earthquake that will sink the plant into the ocean is the only possible answer. How else can the planet and we as a species protect ourselves from radiation from damaged nuclear power plants that could do as much damage to the world as a nuclear war?
Fukushima Daiichi Site:
Cesium-137 is 85 times greater than at Chernobyl Accident
It’s highly unlikely that you’ll ever see this in the mainstream media. But there are some honest Japanese who aren’t afraid to tell us how serious things are at the Fukushima-Daiichi nuclear power plant. Check this link for the full story, from which we excerpted the following.
|In recent times, more information about the spent fuel situation at the Fukushima-Dai-Ichi site has become known. It is my understanding that of the 1,532 spent fuel assemblies in reactor No. 304 assemblies are fresh and unirradiated. This then leaves 1,231 irradiated spent fuel rods in pool No. 4, which contain roughly 37 million curies (~1.4E+18 Becquerel) of long-lived radioactivity. The No. 4 pool is about 100 feet above ground, is structurally damaged and is exposed to the open elements. If an earthquake or other event were to cause this pool to drain this could result in a catastrophic radiological fire involving nearly 10 times the amount of Cs-137 released by the Chernobyl accident.
The infrastructure to safely remove this material was destroyed as it was at the other three reactors. Spent reactor fuel cannot be simply lifted into the air by a crane as if it were routine cargo. In order to prevent severe radiation exposures, fires and possible explosions, it must be transferred at all times in water and heavily shielded structures into dry casks.. As this has never been done before, the removal of the spent fuel from the pools at the damaged Fukushima-Dai-Ichi reactors will require a major and time-consuming re-construction effort and will be charting in unknown waters. Despite the enormous destruction cased at the Da–Ichi site, dry casks holding a smaller amount of spent fuel appear to be unscathed.
Based on U.S. Energy Department data, assuming a total of 11,138 spent fuel assemblies are being stored at the Dai-Ichi site, nearly all, which is in pools. They contain roughly 336 million curies (~1.2 E+19 Bq) of long-lived radioactivity. About 134 million curies is Cesium-137 — roughly 85 times the amount of Cs-137 released at the Chernobyl accident as estimated by the U.S. National Council on Radiation Protection (NCRP). The total spent reactor fuel inventory at the Kagoshima-Daichi site contains nearly half of the total amount of Cs-137 estimated by the NCRP to have been released by all atmospheric nuclear weapons testing, Chernobyl, and world-wide reprocessing plants (~270 million curies or ~9.9 E+18 Becquerel).
It is important for the public to understand that reactors that have been operating for decades, such as those at the Fukushima-Dai-Ichi site have generated some of the largest concentrations of radioactivity on the planet.
