Big Typhoons May Collide Off Honshu

      

Double whammy feared; Izu braces for the worst

japantimes.co.jp - by Tomohiro Osaki - October 23, 2013

Less than a week after being hit by the largest typhoon in a decade, Tokyo is bracing for another strong storm that will likely reach the area Saturday, and it may get merged with an even stronger approaching tempest.

Though less powerful than Typhoon Wipha, incoming tropical cyclone Francisco is rated as “strong,” the Meteorological Agency said. But on a possible collision course is Typhoon Lekima, considered “more fierce.”

Weather Channel, Oct. 18, 2013 at 9:45p ET: Super Typhoon Francisco Brushes Guam, Could Threaten Japan Next Week [...] A tropical cyclone is dubbed a “super typhoon” when maximum sustained winds reach at least 150 mph – the equivalent of a Category 4 hurricane on the Saffir-Simpson scale. [...] Conditions appear favorable for development [... allowing] the typhoon to strengthen in intensity, possibly to 160 mph (Category 5 status) over the next few hours. After that, Francisco will move into a region of cooler ocean temperatures, which cause the typhoon to weaken. Francisco may threaten southern Japan early next week, however the current forecast from the Joint Typhoon Warning Center indicates that the typhoon will be much weaker by that point. That said, intensity forecasts at five days out in time can be highly uncertain [...]

Three Mile Island Veteran Optimistic on Fukushima Fuel Removal

The first removal of nuclear fuel rods next month from the stricken Fukushima atomic station should be successful based on findings that the rods -- each about twice the average weight of a sumo wrestler -- appear undamaged from an explosion at the site almost three years ago.

That’s the view of Lake Barrett, a former U.S. Nuclear Regulatory Commission official appointed last month as an adviser to Tokyo Electric Power Co. (9501), the operator of the wrecked Fukushima Dai-Ichi nuclear plant.

IAEA Expert Remediation Mission to Japan Issues Preliminary Report

                                          

21 October 2013 | Tokyo -- The International Atomic Energy Agency (IAEA)'s international expert mission to review remediation efforts in areas affected by the Fukushima Daiichi accident concluded today with the presentation of a Preliminary Summary Report to Japan's Senior Vice-Minister of the Environment, Shinji Inoue.

The Follow-up IAEA International Mission on Remediation of Large Contaminated Areas Off-site the Fukushima Daiichi NPS recognised the huge effort and enormous resources that Japan is devoting to its remediation strategies and activities, with the aim of improving living conditions for people affected by the nuclear accident and enabling evacuees to return home.

The Mission Team highlighted important progress since the first IAEA remediation mission in October 2011, noted that Japan had made good use of advice from that earlier Mission, and offered fresh advice in a number of areas where it is still possible to further improve current practices, taking into account both international standards and the experience of remediation programmes in other countries.

Latest Radioactive Leak at Fukushima: How Is It Different?

The latest leakage at the crippled Fukushima Daiichi nuclear plant comes from a different, more contaminated water source and raises new questions about TEPCO's ability to manage the crisis.

nationalgeographic.com - by Patrick J. Kiger - August 21, 2013

In the latest crisis to strike the Fukushima-Daiichi nuclear power plant in Japan, operator Tokyo Electric Power (TEPCO) has discovered that 300 tons (nearly 72,000 gallons) of highly radioactive water has leaked from a holding tank into the ground over the past month.

Fukushima Reactor Water Level Shallower Than Thought

yomiuri.co.jp - March 28, 2012

The water level in the containment vessel of the No. 2 reactor at the Fukushima No. 1 nuclear power plant is only about 60 centimeters deep, far shallower than previously assumed levels of about four meters, according to Tokyo Electric Power Co.

The lower-than-expected water level was discovered for the first time when the power utility used an industrial endoscope to check the crippled reactor's interior on Monday, TEPCO said.

According to some experts, it is possible that nuclear fuel that melted through the reactor's pressure vessel and accumulated on the bottom of the containment vessel in the aftermath of the March 11 earthquake and tsunami may not be completely covered in the water.

TEPCO said the water temperature in the vessel remained relatively low within a range of 48.5 C to 50 C. The discovery of the unexpectedly shallow water level will not affect TEPCO's judgment that the reactor is in a state of "cold shutdown."

New NRC Hazard Analysis Earthquake Study Released

submitted by Kay Goss

                 

US NRC study released today on "New Seismic Model Will Refine Hazard Analysis at U.S. Nuclear Plants" and performs studies at many central and eastern U.S. susceptible locations. The Central and Eastern United States Seismic Source Characterization for Nuclear Facilities (CEUS SSC) Project was conducted from April 2008 to December 2011 to develop a new, regional seismic source model for use in conducting and reviewing probabilistic seismic hazard analyses (PSHAs) for nuclear facilities in the CEUS. PSHA is a method for assessing site-specific seismic hazard that includes getting the best estimate of ground motions and a transparent quantitative accounting of uncertainty. The results of PSHA are used in seismic design and in calculating seismic risk.

Research - Radioactive Contamination

Mike,
A new report was published on November 14, 2011.

Radioactive substances spewed out by the quake-stricken Fukushima No. 1 nuclear power plant have likely spread to western Japan and Hokkaido, according to a team of Japanese, U.S. and European scientists.

Their findings were published in the Nov. 14 online edition of the Proceedings of the U.S. National Academy of Sciences.

Traces of Radiation Found in 2 Whales Off Japan

TOKYO (AP) — Japanese whalers caught two animals along the northern coast that had traces of radiation, presumably from leaks at a damaged nuclear power plant, officials said Wednesday.

Two of 17 minke whales caught off the Pacific coast of Hokkaido showed traces of radioactive cesium, both about one-twentieth of the legal limit, fisheries officials said.

They are the first whales thought to have been affected by radiation leaked from the Fukushima Dai-ichi nuclear plant since it was hit by a March 11 earthquake and tsunami.

"The levels are far below the limit, and the meat from the catch is safe for consumption," Fisheries Agency official Kosei Takekoshi said.
