• Leading U.S. scientists support Iran deal

    Twenty-nine of leading U.S. scientists – among them Nobel laureates, nuclear weapons designers, and former White House and congressional science advisers – on Saturday sent a letter to President Barack Obama to express their support of the nuclear deal reached between the P5+1 powers and Iran, and to stress that in their professional assessment the deal “technically sound, stringent and innovative.” Most of the twenty-nine who signed the letter have held Q clearances, a top security clearance which grants its holders access to a special category of secret information related to the design of nuclear weapons. The scientists’ letter as describe as “without precedent” the deal’s explicit ban on Iran’s research on nuclear weapons “rather than only their manufacture,” as prescribed in the 1968 Non-Proliferation Treaty (NPT).

  • The Joint Comprehensive Plan of Action “kicks the can down the road”: How to prepare for the day when the can finally lands

    The Institute for Science and International Security has published a series of briefs analyzing different aspects of the agreement reached between the P5+1 and Iran over the latter’s nuclear program. One brief deals with what the United States and the other world powers need to do now to prepare for what may happen in Iran in ten to fifteen years when many of the limits the agreement imposes on Iran’s nuclear activities will expire. The agreement does not prohibit Iran from building a large uranium enrichment capability and even a reprocessing, or a plutonium separation, capability. The agreement essentially delays the day when Iran reestablishes a nuclear weapons capability and possibly builds nuclear weapons, that is, the agreement essentially “kicks the can down the road.” Prudent planning requires careful efforts now to prepare for the day when the can lands.

  • Inspection regime in Iran informed by lessons from Iraq experience

    Many critics of the agreement reached between the P5+1 and Iran over Iran’s nuclear program are especially concerned with the inspection regime negotiated in Geneva. The initial goal of the world powers was, in President Barack Obama’s words, an “Anywhere, anytime” inspections, but the deal finally reached saw the two sides agree to inspection procedures which fall short of that goal.

  • The science behind the deal

    The main U.S. objective of the deal with Iran is to decrease the riskiness of Iran’s civilian nuclear program to a point which (1) future nuclear weapon production would be unlikely, and (2) if Iran does cheat, it would be detected with reasonable certainty. Have the objectives been achieved in the deal signed 14 July? It is important to keep in mind that it is not reasonable for opponents of the deal to demand 100 percent certainty in verifying the agreement and it is also not necessary. A cost-benefit analysis is always done to determine what is feasible. Often this is not understood, and unreasonable demands may be placed on the verification regime.

  • NNSA should consider more than one alternatives for lithium production: GAO

    An isotope of lithium is a key component of nuclear weapons and is essential for their refurbishment. The National Nuclear Security Administration’s (NNSA) halted certain aspects of its lithium production operation — conducted at its Y-12 National Security Complex in Oak Ridge, Tennessee — in May 2013 due to the condition of the site’s 72-year old lithium production facility. Y-12 management concluded that usable lithium could run out without additional actions. In response, NNSA developed a strategy which proposed a new lithium production facility by 2025 and identified “bridging” actions needed to meet demand through 2025. GAO says that NNSA should give consideration to other alternatives for addressing the coming lithium production crunch.

  • First of three flight test for B61-12 gravity bomb completed

    The U.S. Air Force (USAF) and National Nuclear Security Administration (NNSA) completed the first development flight test of a non-nuclear B61-12 gravity bomb at Tonopah Test Range in Nevada on 1 July 2015. This test is the first of three development flight tests for the B61-12 Life Extension Program (LEP), with two additional development flight tests scheduled for later this calendar year. The B61-12 LEP refurbishes both nuclear and non-nuclear components to extend the bomb’s service life while improving its safety, security, and reliability.

  • The nuclear deal with Iran: Highlights

    The details of the Joint Comprehensive Plan of Action signed yesterday, 14 July 2015, in Vienna are complicated and mostly of technical nature, but the agreement itself is not much more than a bargain between the world’s powers and Iran: Iran agreed to accept the imposition of exceedingly strict limits on its nuclear program in exchange for a return of its frozen assets and the lifting of the crippling sanctions the United States, the EU, and the UN had imposed on it for its refusal to live within the strictures of the Nuclear Non-Proliferation Treaty (NPT), of which it is a member.

  • The military option against Iran: Not a single strike, but a sustained campaign

    The new, 30,000-pound Massive Ordnance Penetrator, or MOP, is one weapon the United would likely use if a decision is made to strike Iran’s nuclear facilities. Military analysts say that while the destruction of Iran’s nuclear infrastructure will not be easy, it can be done. They also agree that it would halt Iran’s nuclear program only temporarily, and that it would take Iran three to four years to rebuild its nuclear capacity. “A single military strike would only delay an Iranian drive for a finite period so a credible military option would have to envision a long-term campaign of repeated follow-up strikes as facilities are rebuilt or new targets identified,” says one analyst. “This is within the U.S. capability, but would require policy consistency and sustained determination across several U.S. administrations. What is crucial is not the bomb, but a multiyear campaign of vigilance and precise intelligence of new targets.”

  • Iran offered nuclear help in exchange for tighter restrictions on weapons-related technology

    The talks between the P5+1 and Iran over a nuclear deal resumed on Wednesday, and sources say that Western powers have offered Iran high-tech reactors in exchange for further curbs on those aspects of Iran’s nuclear program which would make it possible for it to “break out” of the confines of the deal and build a nuclear weapon. The Western powers promised to supply Iran with light-water nuclear reactors instead of its nearly completed heavy-water facility at Arak, which could produce enough plutonium for several bombs a year if completed as planned. One of the major goals of the P5+1 negotiators has been to reduce the Arak reactor’s plutonium output, thus blocking Iran’s plutonium path to the bomb. It offers cooperation with Iran in the fields of nuclear safety, nuclear medicine, research, nuclear waste removal, and other peaceful applications.

  • Iran stored nuclear equipment in Sudanese arms factory destroyed by Israel in October 2012: Saudi memo

    In early October 2012 Israeli planes destroyed the Yarmouk arms factory near Khartoum, Sudan’s capital – 1,300 miles from Israel. At the time, it was reported that the target of the Israeli attack were chemical munitions Iran stored at the site with the intention of delivering them to Hamas. It now appears that the October 2012 Israeli attack targeted more than chemical weapons. According to officials in the Saudi embassy in Khartoum, Iran, in early 2012, shipped advanced nuclear equipment to Sudan, and stored that equipment at the sprawling site. The Saudi embassy memo, dated February 2012 and marked as “very secret,” was leaked last week by the WikiLeaks groups along with what the group claimed were 60,000 other official Saudi communications.

  • U.S. assumptions about key elements of Iran deal unrealistically “rosy”: Critics

    Critics of the emerging nuclear deal with Iran say that there ae two major risks which are not adequately addressed in the discussions over the agreement. The first is that Iranians will cheat, and continue to move toward the bomb covertly. The second, more subtle, problem is the combination of the State Department’s habit of tardy reporting, and the nuclear infrastructure and materials Iran will be allowed to keep, which will make its “breakout” time — that is, the time it will need to build a bomb from the point of making a decision to do so — exceedingly short.

  • Multinational control of enrichment “the only realistic way” to reduce nuclear risks

    Within the next two weeks, or soon after, the United States and five world powers hope to finalize a nuclear deal with Iran to limit its nuclear activities in exchange for a relaxing of international economic and financial sanctions. What, however, happens in ten years when some of the key restrictions being discussed begin to phase out? One of the biggest concerns is Iran’s uranium enrichment program, which uses high-speed centrifuges to produce uranium enriched to a level appropriate for nuclear power reactor fuel. Enrichment plants like this can be quickly reconfigured to produce “weapon-grade” uranium. A new report suggests that “Reducing proliferation risks by ending national control over dangerous civilian nuclear activities is an important idea with a long history,” in the words of one of the report’s authors. “As civilian nuclear technology keeps spreading, multinational control may offer the only realistic way to stop the spread of nuclear weapons capability.”

  • 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.
