  • Nuclear powerHopes for quicker, cheaper ways to build nuclear power plants dim

    Promises of building a more cost effective U.S. nuclear industry continue to face setbacks as alternative energy sources like natural gas become cheaper for utilities, while new models for nuclear plants face cost overruns.Nuclear reactor developers sought to build new plants using prefabricated Lego-like blocks to save time and reduce labor costs, butanalysts consider the designs for the new nuclear reactors to be difficult or impossible to build.

  • Nuclear safetyU.S. nuclear plant licensees should seek, act on nuclear plant hazards information

    A new report concludes that the overarching lesson learned from the 2011 Fukushima Daiichi nuclear accident is that nuclear plant licensees and their regulators must actively seek out and act on new information about hazards with the potential to affect the safety of nuclear plants. The committee that wrote the report examined the causes of the Japan accident and identified findings and recommendations for improving nuclear plant safety and offsite emergency responses to nuclear plant accidents in the United States.

  • Radiation risksDOE chief to visit WIPP to discuss funding for recovery efforts

    Energy Secretary Ernest Moniz will visit Carlsbad, New Mexico on 12 August to discuss funding for the Waste Isolation Pilot Plant (WIPP) recovery efforts.Traces of americium and plutonium were released from a nuclear waste drum on 14 February and were detected in the air almost a half-mile outside WIPP. On 15 May, the DOE confirmed that the damage occurred on a waste drum from Los Alamos National Laboratory.

  • Nuclear wasteFire shuts down nuclear repository, but DOE still recognizes operator for “excellent” performance

    Five days after an underground truck fire closed the Waste Isolation Pilot Plant (WIPP), the Energy Department (DOE) awarded Nuclear Waste Partnership (NWP), the operating contractor of the nuclear repository, $1.9 million for “excellent” performance during the past year.Shortly after the truck fire, WIPP was shut down because of radiation leak, Still, “No federal or contractor official has lost their job, been transferred, been moved off the WIPP contract or otherwise held accountable. No leadership has changed at the federal level. No company has lost a contract,” noted an industry observer.

  • Nuclear wasteJapan testing underground nuclear waste storage depot, despite local concerns

    Data is being collected at the Horonobe Underground Research Center, in Horonobe, Japan to determine whether the site is able to begin storing radioactive waste in conditions which could last for 100,000 years.Japanese utility systems have produced more that 17,000 tons of “spent” nuclear fuel rods from power plants which are no longer useful but are expected to remain radioactive for around several thousand years.

  • Radiation risksLos Alamos lab admits mishandling toxic waste, causing repository radiation leak

    In a letter addressed to the New Mexico Environment Department (NMED), lab officials at Los Alamos National Laboratory (LANL) have admitted to mishandling toxic waste shipped to the Waste Isolation Pilot Plant (WIPP) in Carlsbad, New Mexico, the nation’s only permanent repository for plutonium-contaminated waste from government nuclear facilities.

  • Nuclear powerAs Baby Boomers retire, nuclear industry faces manpower shortages

    Many nuclear power plants in the United States are facing an employment and training crisis as their largely Baby Boomer-generation (1946-64) workforce begins to retire. The nuclear industry is making an effort to usher in new and better-trained workers — many from university programs and former military service — to fill in the gaps created by retirement-aged engineers.

  • Nuclear safetyMaking nuclear power plants more resilient during earthquakes

    Researchers in Finland are examining current nuclear power plants’ structure to see where improvements could be made to make them more resilient during earthquakes. Finland currently is building new nuclear power plants, and within ten years, the country expects to be getting 60 percent of its electricity from nuclear plants.

  • Radiation risksUsing cosmic rays to peer inside Fukushima Daiichi reactors

    Muon radiography (also called cosmic-ray radiography) uses secondary particles generated when cosmic rays collide with upper regions of Earth’s atmosphere to create images of the objects that the particles, called muons, penetrate. The process is analogous to an X-ray image, except muons are produced naturally and do not damage the materials they contact. Los Alamos National Laboratory the other day announced an impending partnership with Toshiba Corporation to use muon tomography safely to peer inside the cores of the Fukushima Daiichi reactors and create high-resolution images of the damaged nuclear material inside without ever breaching the cores themselves. The initiative could reduce the time required to clean up the disabled complex by at least a decade and greatly reduce radiation exposure to personnel working at the plant.

  • EnergyCarbon-cutting regulations may boost prospects of nuclear power plants

    In a report issued last Thursday, Standard & Poor’s Ratings Services (S&P) predicted that new nuclear plant construction could benefit from the Environmental Protection Agency’s (EPA) recent carbon-cutting guidelines for current natural gas power plants.

  • Nuclear operationsNNSA says security at Y-12 National Security Complex has improved

    Retired Air Force lieutenant-general and now National Nuclear Security Administration(NNSA) chief Frank Klotz asserted last week that security at the Y-12 National Security Complexat Oak Ridge National Laboratory(ORNL) has improved significantly since a 28 July 2012 break-inat the plant when three aging peace activists, led by an 82-year old nun, managed to breach the facility’s supposedly impregnable perimeter security systems.

  • Nuclear wasteNRC will not require nuclear plants to transfer waste to dry cask storage

    Cooling pools on the grounds of U.S. nuclear plants, where toxic nuclear waste is stored, are near capacity, and in 2010 the plug was pulled on the Yucca Mountain centralized national nuclear waste repository, meaning that for the foreseeable future radioactive will continue to accumulate on site at the more than 100 nuclear power plants. Lawmakers called on the U.S. Nuclear Regulatory Commission (NRC) to require nuclear plants to hurry the transfer of spent fuel from the cooling pools to dry cask storage, which scientists consider much safer. The NRC, however, has decided that, at least for now, there is now reason to require nuclear plants to do so.

  • Nuclear facilitiesCritics: U.K. nuclear watchdog plagued by “indefensible” conflicts of interest

    Britain’s nuclear watchdog, the Office for Nuclear Regulation(ONR), is receiving technical advice from companies it is tasked with monitoring, leading industry insiders to accuse the watchdog of accepting advice tainted with “unbelievable” conflicts of interest. ONR’s chairman, Nick Baldwin, noted that the agency is concerned about possible conflicts of interest, but that there is a “small gene pool” of firms capable of advising ONR inspectors.

  • Nuclear facilitiesGuard fired for Y-12 breach says he was made a scapegoat for contractor’s failings

    Kirk Garland, a security guard at the Y-12 National Security Complex in Oak Ridge, Tennessee, was fired from his job two weeks after three aging peace activists, led by an 82-year old nun, managed, on 28 July 2012, to breach the facility’s supposedly impregnable perimeter security systems, then loiter, unnoticed, on the grounds of the facility, where bomb grade uranium is stored. The activists had enough time to spray-paint peace messages and Bible verses on walls, slosh the walls with human blood, and wrap one of the buildings with crime-scene tape. In an arbitration hearing, Garland argued that he was made a scapegoat for the larger failings of the then-security contractor,Wackenhut Services.

  • Nuclear wasteU.S., industry grappling with a growing nuclear waste problem

    Thirty years ago congress voted to fund the building of centralized nuclear waste repository at the Yucca Mountain site in Nevada. Four years ago to Obama administration pulled to plug on the project, and nuclear wasted has continued to accumulate on the grounds of nuclear plants – active and shuttered – around the United States. As of May 2013, the U.S. nuclear industry had 69,720 tons of toxic nuclear waste to deal with. The administration strategy calls for a short-term centralized storage facility by 2025, and a permanent national geological repository by 2048.
