• Iran’s nukesIran officially begins unlimited production of enriched uranium, heavy water

    Iran has officially ended its compliance with several commitments under the 2015 nuclear accord, an informed official in the country’s atomic energy body told local media channels on Wednesday.

  • Iran’s nukesIran suspending some nuclear deal commitments

    Iranian President Hassan Rouhani announced Wednesday his country will suspend its compliance with prohibitions on stockpiles of enriched uranium and heavy water that were imposed as part of the 2015 international agreement on its nuclear program.

  • Nuclear proliferationSecond edition of Nuclear Nonproliferation Textbook

    Brookhaven Lab has updated and published the second edition of the Nuclear Nonproliferation Textbook, originally published in 2013. The new release describes important changes that have since been implemented in the International Atomic Energy Agency’s (IAEA) safeguards system for the peaceful use of nuclear energy and documents the IAEA’s verification role in Iran that began in 2015.

  • North Korea’s nukesU.S. should reject partial North Korean “concessions”: Experts

    The failure to reach an agreement at last week’s Hanoi meeting between President Donald Trump and the North Korean leader Kim Jong-un in Hanoi is but the latest indication that the differences between the United States and North Korea over the latter’s nuclear weapons capability are deep and complex.

  • Nuclear safetyBetter monitoring of nuclear power plants, nuclear proliferation

    The United Kingdom is investing nearly £10 million (about $12.7 million) in a joint project with the United States to harness existing particle physics research techniques to remotely monitor nuclear reactors. Expected to be operational in 2024, the Advanced Instrumentation Testbed (AIT) project’s 6,500-ton detector will measure the harmless subatomic particles called antineutrinos that are emitted by an existing nuclear power plant 25 kilometers, or about 15.5 miles, away.

  • Iran’s nukesBritain’s MI6 chief visited Israel to discuss Iran’s nuclear threat

    The chief of Britain’s MI6 intelligence service recently visited Israel to discuss the threat posed by Iran’s nuclear program. Israeli intelligence believes that Iran is “making preparations” to develop nuclear weapons without blatantly violating the 2015 deal. However, the Islamic Republic has not yet made the political decision to break out, according to the Israeli assessment.

  • Iran’s nukesWeapons experts: Archives show that Iran was likely developing nuclear warheads

    Documents in the Iranian nuclear archive captured by Israel last year show that Iran built an underground facility, which was likely used for the development of nuclear warheads, a paper published Friday by the Institute for Science and International Security charged.

  • Iran’s nukesWeapons experts: Iranian nuclear archive shows that Iran lied about uranium mine

    Nuclear weapons experts, who have reviewed the Iranian nuclear archive that Israel recovered from a Tehran warehouse, concluded that Iran lied that a uranium mine was under control of its civilian atomic energy agency.

  • Nuclear wasteU.S. must start from scratch with a new nuclear waste strategy: Experts

    The U.S. government has worked for decades and spent tens of billions of dollars in search of a permanent resting place for the nation’s nuclear waste. Some 80,000 tons of highly radioactive spent fuel from commercial nuclear power plants and millions of gallons of high-level nuclear waste from defense programs are stored in pools, dry casks and large tanks at more than seventy-five sites throughout the country. “No single group, institution or governmental organization is incentivized to find a solution,” says one expert.

  • Nuclear wasteWhat should we do with nuclear waste?

    The failure to develop a strategy for permanent storage and disposal of this fuel costs Americans billions of dollars a year and jeopardizes the future of nuclear power as a carbon-free source of energy, according to nuclear security expert Rodney C. Ewing. He recommends a new not for profit independent corporation that’s owned and supported by the utilities that operate nuclear power plants. The new organization would deal only with spent fuel from commercial reactors. Defense waste is an entirely different issue and should, at this time, remain the responsibility of the federal government.

  • Iran’s nukesWeapons experts: Satellite images confirm Netanyahu’s claims about Iran’s nuclear warehouse

    Satellite images obtained over the summer confirm charges made by Israeli Prime Minister Benjamin Netanyahu in September that Iran had a secret nuclear warehouse in Tehran, a team of weapons inspectors wrote in a paper.

  • Iran’s nukesIran planned to build five 10-Kt bombs by 2003: Nuclear experts

    The Institute for Science and International Security published a paper Tuesday containing new details about Iran’s nuclear weapons program and demanding that the International Atomic Energy Agency ensure that Iran’s nuclear weapons program is “ended in an irretrievable permanent manner.” According to the report, Iranian documents show that Iran had specific plans to build five 10-kiloton nuclear devices by 2003. The plans from the archive show that Iran’s planning for these weapons was very detailed, including expected costs and a timetable.

  • Nuclear forensicsLevitating particles could lift nuclear detective work

    Laser-based ‘optical tweezers’ could levitate uranium and plutonium particles, thus allowing the measurement of nuclear recoil during radioactive decay. This technique, proposed by scientists at Los Alamos National Laboratory, provides a new method for conducting the radioactive particle analysis essential to nuclear forensics.

  • Iran’s nukesNuclear experts: Archive shows that Iran had “advanced capabilities” to produce nukes

    The documents in an archive seized by Israel show that Iran had “more advanced capabilities to make nuclear weapons themselves,” according to a paper being prepared by an anti-proliferation think tank, experts say. Foreign Policy, which saw an early draft of the paper being produced by the Institute for Science and International Security, reported that the information contained in the archive “demonstrates that Washington and the IAEA were constantly underestimating how close Tehran was to a bomb.”

  • Iran’s nukesNuclear experts: Documents show Iran’s weapons work was more advanced than previously known

    The documents recovered by Israeli intelligence from Iran’s hidden nuclear archive show “that Iran conducted far more high explosive tests at the site than previously understood,” according to a paper published on Tuesday by the Institute for Science and International Security.
