  • DetectionNew detection technology to help combat nuclear trafficking

    According to the International Atomic Energy Agency (IAEA), the greatest danger to nuclear security comes from terrorists acquiring sufficient quantities of plutonium or highly enriched uranium (HEU) to construct a crude nuclear explosive device. The IAEA also notes that most cases of illicit nuclear trafficking have involved gram-level quantities, which can be challenging to detect with most inspection methods. Special algorithm coupled with commercial X-ray scanners allows detection of small amounts of fissile materials in luggage.

  • NukesFloating nuclear plants could ride out tsunamis

    By David L. Chandler

    When an earthquake and tsunami struck the Fukushima Daiichi nuclear plant complex in 2011, neither the quake nor the inundation caused the ensuing contamination. Rather, it was the aftereffects — specifically, the lack of cooling for the reactor cores, due to a shutdown of all power at the station — that caused most of the harm. A new design for nuclear plants built on floating platforms, modeled after those used for offshore oil drilling, could help avoid such consequences in the future. Such floating plants would be designed to be automatically cooled by the surrounding seawater in a worst-case scenario, which would indefinitely prevent any melting of fuel rods, or escape of radioactive material.

  • Nuclear securityLt. Gen. Frank Klotz (Ret) confirmed as DoE undersecretary for nuclear security, NNSA administrator

    Lieutenant General Frank G. Klotz, United States Air Force (Ret.), was confirmed by the Senate on Tuesday, 8 April 2014, as the Department of Energy’s undersecretary for nuclear security and administrator for the National Nuclear Security Administration (NNSA).

  • Nuclear powerDebate over closing NY’s Indian Point nuclear power plant intensifies

    Indian Pointnuclear power plant, just thirty miles from New York City, has presented a conundrum for environmentalists who advocate clean-air initiatives, caps on carbon emissions, and increasing investment in non-polluting renewable energy sources — but at the same time argue that nuclear power poses a safety hazard to the surrounding area and demand that Indian Point cease operations. Closing the plant would require a long-term energy strategy to replace the 2,000 megawatts the plant currently produces.

  • Nuclear weaponNew consortium dedicated to developing nuclear arms control verification technologies

    A consortium of thirteen universities and eight national laboratories, led by the University of Michigan and including the Los Alamos National Laboratory as a partner, has been awarded a $25 million grant by the NNSA. The consortium is dedicated to the research and development (R&D) of nuclear arms control verification technologies, including nuclear safeguards effectiveness.

  • Plutonium processingAlternative strategy for uranium processing at Oak Ridge

    A group of twenty-five experts referred to as the Red Team, assigned to review alternatives to the Uranium Processing Facility (UPF) at Oak Ridge National Laboratory, have reached a “strong consensus” on what could be an alternative strategy, but will spend the next two weeks polishing their work before presenting it to National Nuclear Security Administration (NNSA). Red Team was instructed to design a way to move uranium processing from Building 9212, Y-12’s Second World War-era center for processing highly enriched uranium, by 2025 and at under $6.5 billion.

  • Plutonium processingNew group formed to monitor Savannah River Site, nuclear waste issues in SE U.S.

    Savannah River Site Watch (SRS Watch), a new public-interest watchdog group, was launched last week in what it said was a response to the need for increased monitoring of the nuclear projects carried out by the U.S. Department of Energy (DOE). The group says it has been formed to focus on an array of nuclear projects now underway at Savannah River Site (SRS), the sprawling 310-square mile complex located near Aiken, South Carolina.

  • Nuclear wasteLos Alamos National Lab resumes transuranic waste shipments

    The waste was received at Waste Control Specialists in Andrews, Texas, where it will be temporarily staged until it can be shipped to the Waste Isolation Pilot Plant (WIPP) near Carlsbad, New Mexico for final disposal. WIPP has been closed since mid-February as a result of radiation leaks in underground storage tunnels. The shipments keep LANL on track to complete 3,706 Campaign on schedule. The campaign aims to remove 3,706 cubic meters of nuclear waste from LANL by 30 June 2014.

  • Nuclear safeguardsNew center will work to improve methods to detect, prevent the spread of nuclear weapons

    The National Nuclear Security Administration (NNSA) has awarded the University of Michigan $25 million to establish the Center for Verification Technology. A team from thirteen universities will work with eight national labs to analyze nuclear nonproliferation efforts, improve technologies for monitoring weapons-grade materials and detecting secret weapon tests, and train the next generation of nonproliferation experts.

  • Dirty bombPossibility of “dirty bombs” a major terrorism threat

    The International Atomic Energy Agency (IAEA) has warned that there were 140 cases of missing or unauthorized nuclear and radioactive material in 2013 — a pressing reminder that the possibility of possession of nuclear materials by terrorist organizations is both real and current.

  • Nuclear hazardsNew drone-based system improves safety of dealing with nuclear hazards

    Hazardous nuclear events have the potential to cause widespread damage to individuals and the environment. Getting close enough to these incidents to accurately assess the problem can be extremely dangerous. Following the incident at the Fukushima power plant in Japan in 2011, for example, helicopter pilots assessing the site were exposed to significant amounts of radiation. Researchers have developed a new system for remote and accurate assessment of dangerous nuclear accident sites.

  • Nuclear wasteObscure element shows promise for nuclear waste storage

    One of the least known elements of the periodic table, californium, may hold the key to the safe and effective long-term storage of nuclear waste, according to new research. The researchers have demonstrated that californium (Cf) has an “amazing” ability to bond and separate other materials, as well as being extremely resistant to radiation damage.

  • Radiation detection New infrared technique remotely to detect dangerous materials

    Researchers say that infrared technology holds the potential to spot from afar whether a site is being used to make nuclear weapons. They developed a model which precisely characterizes the material in each pixel of an image taken from a long-wave infrared camera. The U.S. National Nuclear Security Administration (NNSA) funded the project. The government’s long-term goal for infrared technology is remotely to detect the exact materials, chemicals and gases coming and going from factories or other sites suspected of illegal nuclear production.

  • Radiation risksRadiation damage to Chernobyl’s ecosystems helps spread radioactivity

    Radiological damage to microbes near the site of the Chernobyl disaster has slowed the decomposition of fallen leaves and other plant matter in the area, according to a new study. The resulting buildup of dry, loose detritus is a wildfire hazard that poses the threat of spreading radioactivity from the Chernobyl area.

  • Plutonium processingS.C. politicians want decision to halt work on Savannah River plutonium plant reversed

    Three Republican lawmakers from South Carolina — Senator Lindsey Graham and Representatives Tim Scott and Joe Wilson have – have asked South Carolina governor Nikki Haley to “explore any legal avenues” to prevent the mixed-oxide fuel (MOX) project at the Savannah River Sitefrom shutting down. The administration has decided to put the project on hold after repeated delays and cost overruns averaging 60 percent over the original estimates.
