Even as the situation at the troubled Fukushima Nuclear Reactors … well, remains troubled … the post-game analysis of what went wrong and what could have been done better develops. It is becoming clear that the plant had no real plan for the event of a tsunami even though it was built at an elevation within that affected by historically known and documented tsunami waves, and there is post-hoc confusion and denial related to early screw ups in trying to avoid a meltdown in the reactors (which ended up occurring), for instance.

Highly radioactive water continues to leak out of at least one reactor vessel, and no real progress appears to have been made in securing cooling mechanisms or containing damage to the environment around the plant. The level of radioactivity at the ocean outlet of the plant has increased rather than decreased. It was news when a broken pump in reactor 5 was repaired, but Reactor 5 is stable and was quietly and uneventfully shut down until this pump broke and the reactor started heading for a meltdown (objections that these reactors can’t melt down in three … two … one …). It became especially clear over the last few days that the situation is very far from under control when a regionally typical tropical storm threatened the area and there was no plan for how to address flooding rains and winds or other inclement storm conditions.

Monitoring for radiation exposure of people, plants, landscapes, etc. continues within a climate of increasing uncertainty about the dangers of ionizing radiation. Cattle are being moved out of the area, the snow in the mountains near Fukushima is found to be radioactive, and junior high students are being urged to wear long sleeved shirts, just in case. The Prime Minister is facing a no confidence vote.

The estimated cost of the cleanup (and it is a bit early to estimate, but still..) is about four or five percent of Japan’s GDP.

TEPCO may need to plug leak at Fukushima plant – NHK, May 27

-The operator of the Fukushima nuclear power plant says highly radioactive water continues to leak from a waste disposal facility in the complex.

-TEPCO had transferred to the facility some of the highly radioactive water flooding the basement of the No.3 reactor’s turbine building and nearby tunnel, before it suspended the work earlier this week.

-On Thursday, the transferred water was found to be leaking into an underground passage to another building.

-The utility firm says it is likely that the water level in the facility will stop falling, but added that it may need to plug the leaks.

-The work is expected to be difficult as radiation levels of up to 70 millisieverts per hour have been detected on the water’s surface.

Doubts deepen over TEPCO truthfulness after president’s sightseeing trip uncovered – Mainichi News, May 28

-Suspicions that Fukushima No. 1 Nuclear Power Plant operator Tokyo Electric Power Co. (TEPCO) is hiding information were heightened on May 27 with revelations that its president was not where TEPCO had said he was on the day of the Great East Japan Earthquake.

-TEPCO had claimed that on March 11 its President Masataka Shimizu was on a trip to meet with Kansai-area business leaders. The Mainichi discovered, however, that Shimizu was in fact sightseeing in Nara — a discrepancy that TEPCO now refuses to discuss.

-TEPCO has stated that Shimizu was in the area to meet with Kansai business leaders. However, a top-level executive of the Kansai Electric Power Co. denied that Shimizu had met with anyone from the company, and leaders of other major Kansai corporations also deny having met with Shimizu.

Tepco disclosure said lacking from get-go – Japan Times, May 28

-Tokyo Electric Power Co. did not fully disclose radiation monitoring data after its Fukushima No. 1 nuclear plant was crippled by the March 11 earthquake and tsunami, the government revealed Friday.

-Coming a day after he blasted Tepco’s flip-flop over the injection of seawater into the plant’s reactor 1, Edano said the government "cannot respond to this matter on the premise" that no more undisclosed information will emerge.

-"There is a distinct possibility that there is still more," he said, urging Tepco to accurately and swiftly report the truth to the government.

-A senior nuclear regulatory official in the United States said Thursday he believed there was a "strong likelihood" of serious core damage and core melt at the Fukushima No. 1 power plant in the days immediately after the crisis began.

-"There were numerous indications of high radiation levels that can only come from damaged fuel at those kinds of levels," said Bill Borchardt, executive director for operations at the Nuclear Regulatory Commission. "So we felt pretty confident that there was significant fuel damage at the site a few days into the event."

-The NRC also had "suspicions" about the conditions of the spent fuel pools, Borchardt said after a speech at the Japan Society in New York.

-Based on that assumption, he said, the NRC recommended that U.S. residents in Japan stay 80 km away from the crippled power plant, which was far beyond the Japanese government’s recommendation for residents within a 20-km radius to evacuate.

Pump failure nearly brings No. 5 to a boil – Japan Times, May 30

-The cause of the pump’s failure was not immediately known but was likely caused by seawater fouling some of its parts, Tepco spokesman Junichi Matsumoto told a news conference Sunday morning.

-Tepco began setting up the backup pump at 8 a.m. Sunday. Matsumoto said Tepco didn’t start until morning because the temperatures of both facilities were rising slowly and an emergency water-injection system was available for unit 5.

-"We judged that it’s better to wait for the morning, rather than to start working while it’s dark. We didn’t think it would pose any immediate danger," Matsumoto said.

-"Even if the temperature (of the core) reaches 100 degrees, the alternative water-injection system is available," he said.

-Still, Matsumoto admitted that "it might have been better" to notify the media sooner about the pump’s failure.

Gov’t to scrap upper limit of radiation exposure for workers at Fukushima plant – Mainichi News, May 30

-The government has decided to abolish the upper cap of radiation exposure for workers at the disaster-crippled Fukushima No. 1 Nuclear Power Plant, drawing concern from experts, it has been learned.

-The move came after it became likely that workers at the Fukushima plant would not be able to be engaged in regular inspections at other nuclear power generation facilities after their stint at Fukushima. However, experts are voicing concerns over the change of policy, saying it could adversely affect the workers’ health.

-The ministry had earlier upgraded the yearly limit of 100-millisievert accumulated exposure in emergencies to 250 millisieverts only for workers at the Fukushima plant, while leaving a decision whether to allow the doses to be combined with those they are exposed to during regular inspections at other nuclear plants unclear.

-In a notice issued on April 28, the ministry clearly stated that workers should be exposed to no more than 100 millisieverts of radiation over a five-year period and that the yearly limit of 50 millisieverts should be upheld for workers at other facilities than the Fukushima plant.

Fukushima Risks Chernobyl ‘Dead Zone’ as Radiation Soars – San Francisco Chronicle, May 30

-Radioactive soil in pockets of areas near Japan’s crippled nuclear plant have reached the same level as Chernobyl, where a "dead zone" remains 25 years after the reactor in the former Soviet Union exploded.

-Soil samples in areas outside the 20-kilometer (12 miles) exclusion zone around the Fukushima plant measured more than 1.48 million becquerels a square meter, the standard used for evacuating residents after the Chernobyl accident, Tomio Kawata, a fellow at the Nuclear Waste Management Organization of Japan, said in a research report published May 24 and given to the government.

-Radiation from the plant has spread over 600 square kilometers (230 square miles), according to the report.

-Soil samples showed one site with radiation from Cesium-137 exceeding 5 million becquerels per square meter about 25 kilometers to the northwest of the Fukushima plant, according to Kawata’s study. Five more sites about 30 kilometers from Dai- Ichi showed radiation exceeding 1.48 million becquerels per square meter.

-When asked to comment on the report today, Tokyo Electric spokesman Tetsuya Terasawa said the radiation levels are in line with those found after a nuclear bomb test, which disperses plutonium. He declined to comment further.
