People living near Sakurajima Volcano, 31 miles from Sendai nuclear plant, have been told to evacuate the area after a government alert was raised to the second highest level. More than 800 tremors have been detected from the volcano, according to the Kagoshima Local Meteorological Observatory.

Around 77 residents were advised to evacuate the area, and 24 had done so by 3.50pm (local time) on 15 August, the Fire and Disaster Management Agency said in a statement.

Volcanic activity at Mount Sakurajima in Kagoshima Prefecture has quieted down after intensifying Saturday morning, but the Meteorological Agency said Monday it will remain on alert for signs of a major eruption.

Tectonic movements indicating swelling of the mountain has also slowed, the agency said. It believes the rise of magma from an underground chamber has subsided for now.

Removing Fuel Rods Poses New Risks at Crippled Nuclear Plant in Japan

TOKYO — It was the part of the Fukushima Daiichi nuclear power plant that spooked American officials the most, as the complex spiraled out of control two and a half years ago: the spent fuel pool at Reactor No. 4, with more than 1,500 radioactive fuel assemblies left exposed when a hydrogen explosion blew the roof off the building.

In the next 10 days, the plant’s operator, the Tokyo Electric Power Company, is set to start the delicate and risky task of using a crane to remove the fuel assemblies from the pool, a critical step in a long decommissioning process that has already had serious setbacks.

Just 36 men will carry out the tense operation to move the fuel to safer storage; they will work in groups of six in two-hour shifts throughout the day for months.

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.

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.

APEC: Joint efforts to reduce disaster risks

Sunday, Nov 13, 2011

The public and private sectors signed a joint statement of intent at Apec to strengthen regional disaster risk reduction and resilience, following US Secretary of State's High-Level Policy Dialogue on Disaster Resiliency yesterday.

The Asia-Pacific Disaster Risk Reduction and Resilient Collaboration joint statement, which was signed by nine organisations at the Sheraton Waikiki, intends to use public private partnership as means to help save lives, ensure economic vitality, and enhance human well-being across the region.

The members also urged more organisations from Apec members to get on-board with their effort to reduce disaster risks and increase resilience in the the Asia-Pacific region.
