  • U.S. to bolster missile defense to meet North Korean threat

    The United States is bolstering the country’s missile defense after a series of explicit nuclear threats from North Korea. The Pentagon will announce Monday that it is deploying fourteen additional ground-based interceptors at missile silos in Alaska and California.

  • New proposals to Iran aim to slow down Iranian nuclear “breakout”

    In two days of talks with Iranian representatives, the P5+1 powers offered Iran a new set of proposals which show a subtle shift in the powers’ position: rather than making it impossible for Iran to produce weapon-grade uranium – by shutting down the Fodro centrifuge farm and demand that Iran ship the uranium it has already enriched to 20 percent out of the country – the new proposals aim to make it more difficult, and slow, for Iran to develop weapon-grade uranium. The assumption undergirding the latest proposals is that if the process of producing weapon-grade uranium would be slowed down, it would be easier for Western intelligence services to discover it, and for military intervention to stop it, before a bomb is being produced.

  • Iran developing plutonium-based nuke capability

    While the world is focusing on Iran’s enriched-uranium nuclear weapons program, evidence has emerged to show that Iran has embarked on a project to make plutonium-based nuclear weapons. This plutonium weapon project is taking place at a facility from which IAEA inspectors have been barred for eighteen months now. Detailed satellite images show that Iran last month has activated the Arak heavy-water production plant, located 150 miles south-west of Tehran. Satellite images of the area around the Arak facility show that numerous anti-aircraft missile and artillery batteries protect the plant — more such missile batteries than are deployed around any other known nuclear site in Iran.

  • Iran installs faster centrifuges at Natanz

    Iranian officials said Wednesday that Iran has begun installing more sophisticated enrichment centrifuges at its Natanz uranium enrichment facility. Speeding up the enrichment process would shorten Iran’s “break out” period: if Iran were to inform the IAEA that it was withdrawing from the nonproliferation treaty (NPT), a step which would allow it to build nuclear bombs without violating the treaty – the time between withdrawal from the treaty and to first nuclear weapons being build will be that much shorter. This will make it that much more difficult for outside powers to intervene to stop the build-up.

  • North Korea’s conducts its third nuclear test

    North Korea early Tuesday (EST) conducted its third underground nuclear test. The South Korean Defense Ministry said its sensors indicated the nuclea test had a yield of six to seven kilotons (about half the size of the bomb dropped in Hiroshima in August 1945). In 2006 North Korea tested a nuclear device with a yield smaller than one kiloton. Its second text, in 2009, was with a yield estimated to be between two to six kilotons. The yield of the test is only one measure of North Korea’s nuclear progress. There are two other important measures: the fissile material used and the device design.

  • Israel, again, beats Syria’s air defense systems

    The Tuesday night Israeli air attacks against targets in Syria raise questions about the effectiveness of the vaunted Syrian air defense system. By extension, similar questions should be asked about the effectiveness of the Iranian air-defense system: both systems use similar technology, and both come from Russia.

  • U.S. bolsters its military capabilities in the Gulf

    The United States has bolstered its military capabilities in the Gulf by stationing six stealth F-22 Raptors at the al Dafra air base, 150 miles from Iran. The F-22 is the most advanced plane in the U.S. arsenal – and also the most expensive, at about $150 million a plane. The F-22 can carry eight smart bombs which it can simultaneously direct at four different targets on the ground – and do so at supersonic speed while evading enemy’s radar.

  • Part Three: Bechtel and the Y-12 security breach

    With an annual security budget of $150 million, the Y-12 Nuclear Complex at Oakridge, Tennessee, prided itself on its high-tech security system built to protect more than 179 tons of uranium. After Sister Megan Rice, age 82, and two confederates, both senior citizens, too — the three were armed with nothing but wire cutters and flashlights — broke into the Y-12 facility on 28 July 2012, one security guard was fired. Numerous investigations and reports, however, show that last July’s incident was but one in a series of security failures and breaches at nuclear sites under the supervision of the National Nuclear Security Administration (NNSA). In May, Sister Rice and her aging collaborators will stand trial. Bechtel, a major contractor sharing responsibility for the documented security lapses at Y-12, has just received a federal nuclear plant security contract worth more than $22 billion.

  • Thorium holds promise of safer, cleaner nuclear power

    Thorium as nuclear fuels has drawbacks, but its main advantage includes generating far less toxic residue. The majority of the mineral is used during the fission process, and it can burn existing stockpiles of plutonium and hazardous waste, saving the need to transport it and bury the waste in concrete. If thorium becomes available as a source of energy in the future, the world will rely less on coal and gas, and wind turbines will become a thing of the past. The risk of a global energy crunch will decrease considerably.

  • Airborne pods tracing nuclear bomb’s origins

    If a nuclear device were to unexpectedly detonate anywhere on Earth, the ensuing effort to find out who made the weapon probably would be led by aircraft rapidly collecting airborne radioactive particles for  analysis; relatively inexpensive UAVs, equipped with radiation sensors and specialized debris-samplers, could fly right down the throat of telltale radiation over a broad range of altitudes without exposing a human crew to hazards

  • France is the forerunner in nuclear power generation – but for how long?

    France has been held up, worldwide, as the forerunner in using nuclear fission to produce electricity; a third of the nation’s nuclear reactors, however, will need replacing in the next decade, and public opinion has shifted toward reducing reliance on nuclear power; does France have the means or desire to unplug from nuclear power?

  • Comparing boost-phase to non-boost-phase ballistic missile defense

    An expert panel set forth to provide an assessment of the feasibility, practicality, and affordability of U.S. boost-phase missile defense compared with that of the U.S. non-boost missile defense when countering short-, medium-, and intermediate-range ballistic missile threats

  • Part Two: NNSA and private contractors’ “nuclear safety culture” responsible for Y-12 security breach?

    After Sister Susan Rice, age 82, and two other senior confederates allegedly broke into the Y-12 National Security Complex at Oak Ridge, Tennessee on 28 July 28th, initial spin on the breach at this highly secured facility focused upon blaming a lone security guard;the security breach at Y-12, however, should be more accurately understood as revealing a more systemic flaw: the breach was not the fault of a single guard, but as a security failure similar to other failures in a number of facilities under the purview of the National Nuclear Security Administration (NNSA) experiencing repeated security and safety lapses

  • U.S. cuts budget for nuclear monitoring at foreign ports

    In 2003 the United States decided to install radiation detection equipment in 100 large ports around the world, and train local personnel in using the equipment, so that ship containers could be scanned for nuclear material before the ship left for the United States; so far, equipment has been deployed in forty-two ports; after GAO criticism of the quality of the scanning equipment and of lack of coordination between two similar container scanning programs, the National Nuclear Security Administration’s 2013 budget will be cut by 85 percent, and further installations will be canceled

  • Israel accused of stealing, revealing IAEA Iran-related documents

    Sources within the IAEA complained that Israel, in its zeal to expose Iran’s nuclear-weapons related activities — and, by implication, its attempt to paint the IAEA as slow and indecisive in its scrutiny of Iran’s nuclear activities – has stolen IAEA secret documents about Iran’s nuclear program and, after editing, gave them to the Associated Press
