• Preventing nuclear terrorism

    Nuclear terrorism remains a real and urgent threat. Despite an array of mechanisms established to combat this threat, several serious problems persist, requiring relentless attention and actions by the United States, Russia, and other responsible nations. These problems include continuing nuclear security vulnerabilities in a number of countries and the continued incidents of illicit trafficking in nuclear materials, radioactive sources, and the various components.

  • Iran indicates willingness to rethink nuclear program in exchange for sanction relief

    As part of a series of steps designed to present post-election Iran as more pragmatic, President Hassan Rouhani and his advisers indicated they would be willing to consider curbs on Iran’s nuclear program in exchange for relief from the crippling economic sanctions imposed on Iran. Some Western experts say that all these steps are more than mere cosmetic changes, while skeptics note that Obama has reached out to Iran before, with no results. Veterans of past nuclear negotiations with Iran also noted that it is likely that Rouhani’s team may not yet fully understand the kinds of concessions that the Islamic republic would be required to make to have the most painful economic sanctions lifted.

  • Fukushima radioactive plume to reach U.S. next year

    The radioactive ocean plume from the 2011 Fukushima nuclear plant disaster will reach the shores of the United States within three years from the date of the incident, but is likely to be harmless, according to a new study. While atmospheric radiation was detected on the U.S. west coast within days of the incident, the radioactive particles in the ocean plume take considerably longer to travel the same distance.

  • 3D Earth model accurately pinpoints source of earthquakes, explosions

    During the cold war, U.S. and international monitoring agencies could spot nuclear tests and focused on measuring their sizes. Today, they are looking around the globe to pinpoint much smaller explosives tests. Researchers are working on developing a 3-D model of the Earth’s mantle and crust called SALSA3D. The purpose of this model is to assist the U.S. Air Force and the international Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) in Vienna, Austria, more accurately locate all types of explosions.

  • Detecting radioactive material smuggled in containers

    Nearly 90 percent of imported and exported goods travel the globe in shipping containers. Roughly 500 million containers travel the sea each year. A Sandia National Laboratories team completed acceptance testing on an enormous mobile scanner — the Mobile Radiation Detection and Identification System (MRDIS) — which makes smuggling radiological materials in containers more difficult.

  • U.S. nuclear facilities vulnerable to terrorist attack: study

    Some U.S. nuclear facilities are inadequately protected against theft of weapons-grade materials and sabotage by terrorists. Terrorist attacks on vulnerable nuclear facilities could trigger a meltdown or lead to a diversion of bomb-grade uranium. The danger is far from hypothetical since the 9/11 hijackers are known to have considered flying a passenger jet into a U.S. nuclear reactor before they settled on the World Trade Center as their main terror target.

  • Nuclear academics, professionals meet for 6th annual ATR NSUF Users Week

    The sixth annual Advanced Test Reactor National Scientific User Facility (ATR NSUF) Users Week was held 10-14 June at University Place, the satellite campus for Idaho State University and University of Idaho in Idaho Falls. This nuclear research-themed week was the user facility’s opportunity to update the user community on nuclear energy issues and tools, conduct a research forum where users can come and present their research, run specialized workshops, and build collaboration among academic, industry and government institutions.

  • Top-secret super-secure vault declassified

    Down a remote canyon near Los Alamos National Laboratory lies a facility known as the Tunnel Vault. Once one of the most secret and secure locations in the United States, it is the original post-Second World War nuclear stockpile storage area. Built between 1948 and 1949, the facility has a formidable security perimeter, a hardened guard tower — complete with gun ports and bulletproof glass — and a series of gates and doors that lead to a 230-foot long concrete tunnel that goes straight into the canyon wall.

  • Specialized gas detection helps prevent nuclear weapons proliferation

    Researchers aim to design a system capable of sensing, from among the loud signals of a lot of gases, the weak signals from specific gases which are signs of nuclear weapons proliferation. The researchers believe their gas correlation technique will prove ideal for a simple, inexpensive sensor to monitor those few illusive gases. This could change how the nation thinks about monitoring the spread of nuclear weapons. Instead of single-point measurements taken with expensive sensors deployed after someone suspects a problem, 24/7 continuous monitoring could find leaks early.

  • Highly portable X-ray imaging system developed

    Los Alamos National Laboratory and Tribogenics have developed the MiniMAX (Miniature, Mobile, Agile, X-ray) camera to provide real-time inspection of sealed containers and facilities.MiniMAX is an alternative to the large, expensive, and fixed facilities presently required for security inspections using X-ray imaging. The complete MiniMAX portable radiography system weighs less than five pounds.

  • Chechen Islamic terrorists threaten February 2014 Winter Olympics in Sochi, Russia

    Doku Umarov, a leading Chechen Islamic rebel, on Wednesday issued a call to Islamist militants throughout the North Caucasus to begin and plan for attacks to disrupt the February 2014 Winter Olympics which will be held in the Black Sea resort of Sochi. Security experts say that securing the games would be a daunting task.

  • U.K. nuclear disaster exercise reveals worrisome lapses in emergency response

    Up to six times a year, U.K. nuclear weapons are transported in heavily guarded convoys between production facilities in Aldermaston and Burghfield in Berkshire, where the nuclear bombs are manufactured, and the Royal Naval Armaments Depot at Coulport on Loch Long in Argyll. The trips are required because scientists must regularly examine the 200 Trident missile warheads in order to make sure they are operationally reliable and properly maintained. Every three years, the U.K. Ministry of Defense (MoD) conducts a drill aiming to test how various agencies respond to an accident involving the convoy carrying the nuclear warheads. An internal report on the last drill notes many problems in the response to the simulated accident, including five-hour wait for weapons experts, confusion over radiation monitoring, and ambulance crews refusing to take contamination victims to hospitals.

  • Laser-driven neutrons to detect nuclear smuggling

    Researchers have successfully demonstrated for the first time that laser-generated neutrons can be enlisted as a useful tool in the war on terror, as Los Alamos shows first nuclear material detection by single short-pulse-laser-driven neutron source.

  • Health impact of Chernobyl accident overestimated: study

    The impact of the Chernobyl nuclear accident has been seriously overestimated, while unfounded statements presented as scientific facts have been used to strangle the nuclear industry, according to Russian researchers.

  • Reducing the volume of nuclear waste

    The nuclear industry seeks to minimize the volume of nuclear waste by extracting the radioactive elements from spent fuel.This relies on exploiting differences in the chemical bonding of uranium. Scientists have found that in some circumstances the bonding may be surprisingly similar, an important discovery which is going to be important in the amelioration of nuclear waste clean-up and devising new atom-efficient catalytic cycles.
