Although TEPCO applied for safety inspections of the Nos. 6 and 7 reactors at the Kashiwazaki-Kariwa plant in late September, the NRA has not held an official safety screening meeting, which will be open to the public, amid concerns over the utility's poor handling of the accident-stricken Fukushima Daiichi plant in Fukushima Prefecture. But the NRA decided during Wednesday's regular gathering of its commissioners that it should at least hold a meeting to listen to the outline of the content of the applications and check whether there are problems that should be addressed.

These tests are to be brought to completion and Dr. Shigeru Mita, director of the clinic, the health of the inhabitants of the capital deteriorated sharply after the catastrophe of Fukushima. In an interview with the website Save children from radiation , Dr. Shigeru Mita said that "the rate of neutrophils (the most abundant type of white blood cells, an essential part of the immune system) in healthy children aged 6to 12 years is 4000, but the patients tested, it is 2500, well below the minimum value allowed so-called "threshold" level which is 3000. I think it shows a serious problem. " This is of course due to the catastrophe of Fukushima. [end snip] [link to nuclear-news.net] It's life as we know it, but only just.

Anonymous Coward User ID: 48719786 Sweden 11/14/2013 04:47 PM Report Abusive Post Report Copyright Violation | Las Vegas Residents Frustrated about Nuclear Waste Shipments LAS VEGAS -- A done deal to bring radioactive materials to southern Nevada is in store for the state's national security site. Las Vegas residents received no input about the waste before the Department of Energy inked a deal and that's what got so many people to show up at a meeting Wednesday night looking for answers. Sixty five miles northwest of the Las Vegas valley is a highly guarded piece of property called the Nevada National Security Site. The area is part of Nevada's very long history of nuclear development and testing. The Department of Energy said it's the perfect place to dispose of deadly nuclear waste. Plans call for as many as 100 canister shipments to arrive from Tennessee as early as next year by truck secretly because the nuclear material could be used to make weapons in the wrong hands. Governor Sandoval and other Nevada leadership have come out opposing the plan saying it opens the door to even more waste coming to our state. There will be 400 canisters of waste brought to the site as the Department of Energy wanted to start the shipments as soon as January, but no firm timeline has been put into place.

A fuel transport container will be placed in the pool using the main crane. Workers will then use the smaller refuelling crane to move fuel assemblies one by one from their vertical storage racks to the container. When this is full it will be sealed, lifted from the water by the main crane, placed on the service floor for decontamination and then taken through a special route to a vehicle that will move it across the site to be unloaded at the site's shared storage facility. This process will be repeated until the pool is empty. With a total of 1533 fuel assemblies in the pool (1331 used, 202 unused) this is expected to take until the end of 2014.

Anonymous Coward User ID: 48719786 Sweden 11/18/2013 12:49 PM Report Abusive Post Report Copyright Violation | The operator of the Fukushima Daiichi nuclear power plant has begun removing nuclear fuel from a storage pool at a damaged reactor building. Workers placed a special fuel transport container in the storage pool of the Number 4 reactor building. The pool holds 1,533 units of nuclear fuel, of which 1,331 are highly radioactive spent fuel. The rest are unused. At around 3PM on Monday, the workers started to hoist the unused fuel units into the steel container, which can store 22 units of fuel. The utility decided to remove these units first as they do not release high levels of radiation and heat. A TEPCO official said that the first fuel unit was moved into the container by 4PM, and that the workers had encountered no problems. [link to www3.nhk.or.jp] . |
Anonymous Coward User ID: 48719786 Sweden 11/18/2013 12:50 PM Report Abusive Post Report Copyright Violation | Nuclear fuel removal procedure The removal of nuclear fuel units from the storage pool of the No.4 reactor building is expected to be completed by the end of next year if all goes well. The pool contains 1,533 units. Nearly 90 percent of them are spent fuel rods, which continue to emit high levels of radiation and heat. Spent fuel contains about one percent plutonium by weight. The spent fuel units at the No.4 reactor building have been in the storage pool for at least 3 years. Each is said to have up to 7,500 trillion becquerels of radioactivity. Because of this, the units are stored in water that can block radiation. [link to www3.nhk.or.jp] . |
Anonymous Coward User ID: 48719786 Sweden 11/18/2013 12:50 PM Report Abusive Post Report Copyright Violation | TEPCO starts removing fuel rods from Fukushima No. 4 reactor TOKYO — Workers at the Fukushima Daiichi nuclear plant on Monday began moving fuel rods from a reactor building, in their most difficult and dangerous task since a tsunami crippled the facility in 2011. Operator Tokyo Electric Power Co (TEPCO) said it had begun the process of removing the uranium and plutonium rods from a storage pool—a tricky but essential step in the complex’s decades-long decommissioning plan. The fuel rods are bundled together in so-called assemblies which must be pulled out of the storage pool where they were being kept when a tsunami smashed into Fukushima in March 2011. There are more than 1,500 such assemblies in the pool. Over the course of two days, the company said it expects to remove 22 assemblies, with the entire operation scheduled to run for more than a year. “At 3:18 p.m., we started to pull up the first fuel assembly with a crane,” a company spokesman said Monday. The huge crane, with a remote-controlled grabber, is being lowered into the pool and then hooked onto the assemblies, placing them inside a fully immersed cask. The 91-ton cask will then be hauled from the pool to be loaded onto a trailer and taken to a different storage pool about 100 ers away. [link to www.japantoday.com] . |

While the process of removing fuel rod assemblies from the spent fuel pool of the No. 4 reactor unit is a milestone toward the decommissioning of Tokyo Electric Power Co.'s Fukushima plant, the work will require careful attention to prevent another radiation leak. "This work is an important step in the decommissioning process that will be carried out over the next 30 to 40 years. We will conduct this work safely and steadily," TEPCO President Naomi Hirose said in a statement. [link to english.kyodonews.jp] Pictures at link. . |
Anonymous Coward User ID: 48719786 Sweden 11/18/2013 12:52 PM Report Abusive Post Report Copyright Violation | TEPCO's ability in doubt as Fukushima plant decommissioning starts Tokyo Electric Power Co. on Monday moved into the actual decommissioning process of the crippled Fukushima Daiichi nuclear power plant, even as doubts swirled over its ability to carry on with the crisis cleanup operations for decades to come. The commencement of the fuel removal from a pool at the damaged No. 4 reactor building was probably one of the few bright pieces of news heard recently from the plant, which has been plagued with frequent radioactive water leaks and other troubles over the past year. But the defueling mission poses another challenge to the utility, with its success or failure expected to affect the following process of retrieving fuel also from the pools of the Nos. 1 to 3 units as well as the melted fuel inside them.

After completing trials using dummy fuel, Tepco reported that preparations for the removal of the first actual assembly began at 9.50am today. A fuel transport container was moved from a temporary storage location on the fifth floor of unit 4's reactor building to the fuel storage pool using the main crane. By 12.30pm, this container had been lowered into the pool ready to accept the initial fuel assembly. The smaller refuelling crane was started up at 3.18pm, marking the start of the fuel removal process. At 3.25pm the transfer of the first fuel assembly from the storage racks into the container began and was completed within two minutes. Three further fuel assemblies had been placed in the container by 6.45pm. Tepco said that it expects to complete the removal of the first 22 unused fuel assemblies within the next two days.

At 0955 (PST), on 11/17/2013 it was discovered that the CMS-SR-13 sample valves would not align to allow monitoring the drywell. The redundant sample rack, CMS-SR-14 is already out of service due to an issue with the sample pump, which is currently awaiting replacement parts. The capability to monitor the drywell for H2 and O2 remotely is non-existent if an emergency situation were to arise because of these two issues. The only method currently available to sample the drywall for H2 and O2 is manually via chemistry procedures. This method would be unavailable in accident conditions because the sample point isolation valves isolate on an accident signal (F or A). Even if the sample points were not isolated, the Chemist would be unable to draw a sample safely during an accident due to radiation levels in the Reactor Building and/or H2 and O2 levels in containment.
