We have all been watching this closely, when you watch this video the crane on the right between Reactor 2 and Reactor 3 turns, and the cable descends to just around the hole area.

Based on the recorded time-histories of the Kinemetrics instrument at the Containment basemat, the August 23, 2011 earthquake exceeded the North Anna DBE in the 2 to 10 Hz range, on average,by about 12% in the North South direction, by about 21% in the vertical direction and non in the E-W direction.

Even in their most dire assessments, some experts had not expected even bursts of re-criticality to occur, because it was unlikely that the fuel would melt in just the right way — and that another ingredient, water, would be present in just the right amounts — to allow for any nuclear reaction. If episodes of […]
Trade Minister Yukuo Edano censured Japan’s nuclear regulator, the Nuclear and Industrial Safety Agency, for failing to report the discovery to the prime minister’s office for hours, according to local media reports. The jumble of material and conditions had seemed very unlikely to be able to produce sustained fission, but intermittent criticalities have long been […]
Japan’s government lowered the maximum allowable exposure for workers at Tokyo Electric Power Co.’s crippled atomic station after radiation levels fell. The limit for new workers at the Fukushima Dai-Ichi nuclear plant was lowered to 100 millisieverts from 250 millisieverts, according to an ordinance by the Ministry of Health, Labour and Welfare that went into […]

The NRC staff is currently reviewing the exemption requests concerning NUHOMS HD-Dry Shielded Canisters being loaded to the incorrect heat load limits at the Surry and North Anna Power Station ISFSIs. The NRC staff has issued a request for supplemental information and Dominion, with the assistance of TN, has provided the ANSYS files used in […]
The operator of the crippled Fukushima Daiichi nuclear power plant says it found in the facility’s No.2 reactor radioactive substances that could have resulted from continuous nuclear fission. The Tokyo Electric Power Company, or TEPCO, said on Wednesday that it detected xenon-133 and xenon-135 in gas taken from the reactor’s containment vessel on the previous […]

Nuclear and Industrial Safety Agency said, analysis, xenon has been confirmed and announced. Xenon was discovered by a short half-life, which had recently occurred in the fission reaction. NISA’s Yoshinori Moriyama said that “localized criticality cannot be ruled out” and that there is also a high probability that Xenon is produced by spontaneous fission of substances […]
Kyushu Electric Power Co. on Nov. 1 restarted the No. 4 reactor at its Genkai nuclear power plant in Saga Prefecture, the first resumption of reactor operations in Japan since the March 11 earthquake. The reactor, which was automatically shut down on Oct. 4 due to equipment trouble caused by human error, is expected to […]
Officials of Tokyo Electric Power Co. (TEPCO) pumped water mixed with boric acid into the No. 2 reactor at the Fukushima No. 1 nuclear power plant early on Nov. 2 after finding traces of xenon, a radioactive gas that might indicate nuclear fission has taken place. [quote] Officials of the company said that some […]
