• Radiation from Fukushima to reach West Coast in April

    On the third anniversary of the Fukushima nuclear plant incident, scientists are reporting that low levels of radiation from the Fukushima plant will reach ocean waters along the U.S. West Coast by April 2014. The scientists say that the radiation will be at levels too low to harm humans, but they call for more monitoring, including at the federal level.

  • Innovative nuclear radiation detector reaches the market

    A handheld radiation camera developed by University of Michigan engineering researchers offers nuclear plant operators a faster way to find potentially dangerous hot spots and leaky fuel rods. The new Polaris-H detector lays a gamma-ray map over an image of a room, pinpointing radiation sources with unprecedented precision. At least four U.S. nuclear power plants are using versions of the camera, which is now available commercially through the U-M spinoff company H3D.

  • Underground recovery process at WIPP begins

    Nuclear Waste Partnership (NWP), the management and operations contractor at the Waste Isolation Pilot Plant (WIPP) for the U.S. Department of Energy (DOE), said it has initiated the first phase of an underground recovery process which will lead to the resumption of nuclear waste disposal operations at WIPP. Initial results show no airborne radioactive contamination in the underground shafts.

  • Scotland demands U.K. govt. apology over radiation leak at MoD nuke facility

    In 2012 the U.K. Ministry of Defense decided to refuel the nuclear reactor on board Britain’s oldest nuclear submarine, HMS Vanguard, after a test reactor operating at the Naval Reactor Test Establishment at Dounreay, Caithness, in Scotland was found to have a small internal leak of radiation. The test reactor had been shut down after the fault was detected, and both the independent Defense Nuclear Safety Regulator and the Scottish Environment Protection Agency (SEPA) had been informed. It now appears that SEPA did not share the information with the Scottish cabinet, or with Alex Salmond, the First Minister of Scotland. Salmond, in a scathing letter to British Prime Minister David Cameron, has demanded an apology from Camron for “disrespecting” the Scottish Parliament and the people of Scotland and for treating both in an “underhanded” manner by not sharing the information about the radiation leaks.

  • Nuclear waste kept in parking area as N.M. repository remains closed

    The federal government’s only underground nuclear waste dump, the Waste Isolation Pilot Plant (WIPP) in New Mexico, remains closed and state environmental officials have set deadlines for the Department of Energy and its contractor-operator of the site to deal with radioactive waste left above ground at the repository. Dozens of drums and containers which have been shipped from federal facilities around the country are being stored in a parking area at the plant, and inside the plant’s waste- handling building.

  • Radiation problems on San Francisco’s Treasure Island persist

    The Army Corps of Engineers created San Francisco’s Treasure Island for the 1939 Golden Gate International Exposition, with plans to turn the island into a civilian airport after the exposition. When the United States entered the Second World War in 1941, the Navy used the island for the Treasure Island Naval Station, where nuclear war training exercises were conducted. The Naval Station was decommissioned in 1993, and parts of the island were transferred to SF for civilian use. Radiation levels on the island are still high, however, and critics charge that the Navy did not do enough to clean the island while downplaying the risks of radiation that still remain.

  • Virtual lab for nuclear waste repository research

    A nuclear waste repository must seal in radioactive waste safely for one million years. Researchers currently have to study repositories and their processes in real underground laboratories, but a virtual underground laboratory will soon simplify their work.

  • Energy Department suspends work on controversial plutonium reprocessing project

    The Obama administration has decided to put on hold its plans to complete construction on a South Carolina reprocessing facility which would convert nuclear weapon-grade plutonium into reactor fuel. The suspension of work on the project is part of the fiscal 2015 budget plan the administration unveiled Tuesday. The project has been hobbled by delays and massive cost-overruns, and experts says security and safety concerns have not been adequately addressed.

  • Proposed 2015 budget cuts funding for nuclear nonproliferation programs

    The Obama administration 2015 budget proposal shows that the administration will spend less on nuclear nonproliferation initiatives in 2015 than it would in 2014. The budget of the National Nuclear Security Administration (NNSA), the agency responsible for various nuclear weapons and nuclear nonproliferation programs, will be cut by 20 percent, from the $1.9 billon Congress approved for fiscal 2014 — which in turn was a $289 million cut from fiscal 2013 levels — to $1.6 billion in 2015.

  • Employees exposed to radiation at nuclear waste disposal site

    Thirteen employees at the Waste Isolation Pilot Plant(WIPP),a nuclear waste burial site in New Mexico, have been exposed to  radioactive radiation after a leak in one of WIPP’s underground tunnels. Energy Department officials say it is too soon to determine the scope of health risks the employees will deal with. The employees inhaled plutonium and americium, both of which can irradiate the body’s internal organs with subatomic particles for a lifetime.

  • Islanders’ radiation worries 60 years after Bikini Atoll atomic test

    Sixty years ago, On 1 March 1954 the United States tested a 15-megaton hydrogen bomb – a thousand times more powerful than the bomb dropped on Hsroshima —- at Bikini Atoll, part of the Marshall Islands. The explosion vaporized one island, and exposed inhabitants on neighboring islands to radioactive fallout. The United States relocated many of the islanders and spent years – and more than $45 million – to clean up and decontaminate the islands, before allowing the relocated inhabitants to return. Many were forced to leave again, however, after they were found to be exposed to residual radiation. From 30 June 1946 to 18 August 1958, the United States conducted 67 atmospheric nuclear tests in the Marshall Islands.

  • Operator of Hanford nuclear disposal site fires scientists who voice safety concerns

    The Hanford project in Washington State is the Department of Energy’s (DoE) largest nuclear cleanup project. DoE plans to transform fifty-six million gallons of radioactive sludge, currently stored in underground tanks, into solid glass. Scientists and engineers who work at Hanford have questioned the effectiveness of the required technology, and have voiced serious concerns about safety issues. Two of those who were the most persistent in voicing their concerns about safety have been fired, and a third one has left his job voluntarily.

  • Cost of plutonium disposal facility skyrockets

    The Mixed Oxide (MOX) nuclear fuel factory at the Savannah River Site in South Carolina, being built to help dispose of cold war-era weapon-grade plutonium, would cost up to $30 billion in addition to the $4 billion spent on construction so far. The staggering cost overruns have led many to call for a new, less expensive solution. Matthew Bunn, a former Clinton White House official who helped develop the plutonium disposal program, agrees that the cost of the MOX factory is excessive. “The things we’re trying to accomplish aren’t worth that amount of money,” he said.

  • IAEA: Iran's stockpile of 20% enriched uranium shrunk under interim nuclear agreement

    The International Atomic Energy Agency (IAEA) reports in its quarterly inspections assessment that the quantity of 20 percent enriched uranium in Iran’s hands has been reduced since last November, when the world’s six powers (P5+1) and Iran have reached an interim agreement on Iran’s nuclear activities. Iran now has 354 pounds of the material — or about one-fifth less than what it had in November. With the right type of centrifuges, it is quicker to enrich uranium from 20 percent to weapon-grade 90 percent than it is to enrich uranium from 1 or 2 percent to 20 percent, so that the smaller the amount of 20 percent uranium a country has, the longer the “breakout” time — the time it would take a country to assemble a nuclear bomb once a decision to do so has been made.

  • Operations at a New Mexico nuclear waste repository suspended because of leaks

    Operations at the Waste Isolation Pilot Plant, or WIPP, a New Mexico burial site for military nuclear waste, were suspended for the fourth day, the Department of Energy said, after sensors picked up radiation leaks inside salt tunnels where the radioactive material is entombed.Officials said no radiation escaped to the surface.This is the second time this month the facility had to suspend operations. Earlier this month operations were halted after a truck caught fire in an underground tunnel.
