• Iran’s refusal to allow inspection of military sites could derail nuclear agreement

    As the five permanent members of the United Nations Security Council— the United States, Britain, France, Russia, and China — plus Germany near a deal to ease international sanctions if Iran agrees to restrictions and monitoring of its nuclear activities, diplomats say Iran’s refusal to provide inspectors access to its military bases could set back the negotiations, which have been in the works for over twenty-months. Deputy Secretary of State Antony Blinken has publicly said that U.S. officials want IAEA inspectors to be given “anywhere, anytime” access to sites where nuclear work is suspected, adding that the Obama administration will not accept a deal unless access is granted “to whatever Iranian sites are required to verify that Iran’s program is exclusively peaceful — period.”

  • U.S. to ratify two long-stalled nuclear terrorism bills

    Deep in the USA Freedom Actwhich was signed into law by President Barack Obama last week, there is a section which will let the United States complete ratification of two-long stalled treaties aimed at preventing nuclear terrorism. “Today, nearly 2,000 metric tons of weapons-usable nuclear materials remain spread across hundreds of sites around the globe — some of it poorly secured,” said former Senator Sam Nunn (D-Georgia), co-chairman of the Nuclear Threat Initiative(NTI). “We know that to get the materials needed to build a bomb, terrorists will not necessarily go where there is the most material. They will go where the material is most vulnerable.”

  • Israel conducted tests to assess the impact of dirty bombs

    Between 2010 and 2014, Israeli scientists at the Dimona nuclear reactor conducted a series of experiments, under the code name “Green Field,” to examine the consequences of a dirty-bomb explosion in Israel. The purpose of the experiments was defensive – to measure the likely effect of a dirty bomb and evaluate countermeasures. The experiments did not evaluate to offensive potential of a dirty bomb.

  • France will not sign off on a nuclear deal with Iran if military sites are off limits to inspectors

    Laurent Fabius, France’s foreign minister, said France will not accept a deal on Iran’s nuclear program if Tehran refuses to allow inspections of its military sites as part of the final agreement. Throughout the negotiations with Iran, France has taken a tougher stance toward Iran than the other negotiating countries, known as the P5 + 1 (the five permanent members of the Security Council – the United States, United Kingdom, Russia, China, and France – and Germany). “France will not accept a deal if it is not clear that inspections can be done at all Iranian installations, including military sites,” Fabius told the national assembly in Paris.

  • T. K. Jones, Pentagon official who argued U.S. could survive an all-out nuclear war, dies

    Thomas K. Jones (he preferred to be called “T. K.”), the deputy under-secretary of defense for research and engineering, strategic and theater nuclear forces, died at 82. He became famous in 1982, when, in an interview with the LA Times, he argued that if the United States had a more robust civil defense, most Americans would survive an all-out Soviet nuclear attack. “You can make very good sheltering by taking the doors off your house, digging a trench, stacking the doors about two deep over that, covering it with plastic so that rainwater or something doesn’t screw up the glue in the door, then pile dirt over it.” He added: “It’s the dirt that does it.” He concluded the interview by saying:  “Turns out with the Russian approach, if there are enough shovels to go around, everybody’s going to make it.”

  • U.S. may support nuke conference proposal challenging Israel’s nuclear program

    Israeli officials expressed concerns that the Nuclear Nonproliferation Treaty Review Conference, which ends today in New York after month-long deliberations, will approve decisions which would pose a major challenge to Israel’s unacknowledged nuclear weapons program. Arab states have already tried, in previous Review Conferences, to push for resolutions calling for making the Middle East a WMD-free zone, in effect, requiring Israel, the only nuclear-armed state in the region, to disarm. Israel’s position, supported by the United States and other countries, is that the nuclear arms issue should be dealt with as only one element of the regional security context. Until the 2010 Review Conference – these conferences meet every five years – the United States, acting on understandings reached between Richard Nixon and Golda Meir in September 1969, supported Israel’s position without much quibbling. In 2010, however, there appeared to be differences emerging between Israel’s and the U.S. approach to regional nuclear disarmament. Israel is worried that the United States, now in negotiations with Iran over the latter’s nuclear program, would support a Spanish compromise proposal which, in Israel’s view, is too close to Egypt’s original proposal which Israel finds unacceptable.

  • U.S. security would be enhanced by minimizing role of nuclear weapons: Report

    Nuclear weapons remain the most potent destructive force known to humanity. Yet, U.S. nuclear policies and doctrines remain encumbered by cold war beliefs in the potential utility of nuclear weapons, even though the United States enjoys a dominant geopolitical position in the world, underpinned by a conventional military superiority greater than any ever known before. A news report argues that U.S. security interests would be better served if the role of nuclear weapons in U.S. strategy were minimized, and the United States, in its declaratory and weapon-development policies, would make it clear that U.S. nuclear weapons would serve only to deter other countries’ use of nuclear weapons against the United States and its allies.

  • Exercise simulates home-grown terrorists, nuclear incident

    In a geopolitical environment with proliferating threats, a Defense Department whole-of-government exercise held 5-8 May provided a realistic way for federal, state, and local experts to interact in simulated situations involving mock home-grown terrorists and a nuclear incident. This year’s Nuclear Weapon Accident Incident Exercise, or NUWAIX 2015, took place on Naval Base Kitsap-Bangor located on the Kitsap Peninsula in the state of Washington. The goal of the exercise was to coordinate the efforts of federal, state, and local agencies in mitigating the consequences of an incident involving a U.S. nuclear weapon in DoD custody at a military base in the continental United States.

  • Iran deal supporters: Comparisons with 1994 North Korea deal not applicable

    Critics of the nuclear agreement between Iran and the P5+1 powers charge that the negotiations, and the impending deal, repeat the mistakes the United States made in the nuclear deal it signed with North Korea in 1994. Supporters of the administration say there is no comparison between what happened twenty years ago and now. One example: the Agreed Framework between the United States and North Korea was a 4-page general document which did not include and reference to enforcement mechanisms should North Korea decide not to comply with the agreement. The emerging agreement with Iran, on the other hand, is a 150-page document dominated by intricate technical specifications and detailed procedures for inspection and verification, followed by specific benchmarks and definitions of violations and non-compliance and the resulting penalties which would be imposed on Iran should such violations occur.

  • Risks associated with nuclear modernization programs

    In the latest issue of the Bulletin of Atomic Scientists, experts from the United States, Russia, and China present global perspectives on ambitious nuclear modernization programs that the world’s nuclear-armed countries have begun.

  • New blood test quickly determines severity of radiation injur

    A novel blood test could greatly improve triage of victims of radiation accidents by rapidly predicting who will survive, who will die, and who should receive immediate medical countermeasures. In pre-clinical trials, the test was able to reveal within twenty-four hours whether survivable doses of radiation or doses that caused severe injury to the bone marrow and other organs would eventually prove fatal. Use of such a test, the researchers said, could “facilitate timely medical intervention and improve overall survival of exposed individuals.”

  • Tests with Sandia’s Davis gun aid B61-12 life extension effort

    Three years of design, planning and preparation came down to a split second, a loud boom and an enormous splash in a successful impact test of hardware in the nose assembly of an unarmed, mock B61-12 nuclear bomb. The Sandia National Laboratories test also captured data that will allow analysts to validate computer models of the bomb, part of Sandia’s decade-long effort in the B61-12 Life Extension Program (LEP). An LEP is a way to extend the life of an aging weapon without adding new military capability. The B61-12 LEP is an $8.1 billion National Nuclear Security Administration (NNSA) program coordinated across the nation’s nuclear security enterprise.

  • Does Iran deal advance or undermine global nonproliferation efforts? Experts disagree

    The White House already points to the potential Iran deal as one of the highlights of Obama’s legacy, as it fulfills both the Obama doctrine of advancing U.S. interests through engagement with America’s adversaries and the vision of a world gradually retreating from furthering nuclear weapons ambitions. Nuclear nonproliferation experts, however, question whether an Iranian nuclear deal, as laid out in the framework agreement reached last month, advances or sets back the nonproliferation agenda and Obama’s vision of ridding the world of nuclear threat.

  • Nuclear forensics science helps thwart terrorist use of nuclear materials

    A nuclear weapon in the hands of terrorists is the stuff of nightmares, especially for U.S. agencies charged with preventing a devastating attack. When security or law enforcement agents confiscate nuclear or radiological weapons or their ingredients being smuggled domestically or internationally, they must quickly trace them back to their source. This is where the science of nuclear forensics comes in. With funding from DHS, Oregon State University has launched a new graduate emphasis in nuclear forensics in OSU’s Department of Nuclear Engineering and Radiation Health Physics.

  • Kerry tells Israelis: U.S. “guarantees” it can prevent Iran from getting the bomb

    U.S. Secretary of State John Kerry tried to assuage concerns in Israel over the nuclear deal with Iran, saying in a Sunday interview on Israel’s Channel 10 TV that “There is a lot of hysteria about this deal.” He added: “I say to every Israeli that today we have the ability to stop them if they decided to move quickly to a bomb, and I absolutely guarantee that in the future we will have the ability to know what they are doing so that we can still stop them if they decided to move to a bomb.”
