In this issue brief, Yusei Nagata, an FAS Research Fellow from MEXT, Japan, analyzes U.S. experts’ opinions and concerns about Japan’s nuclear fuel recycling problem and considers what Japan can (and should) do to solve it.
In this issue brief, FAS President Dr. Charles Ferguson takes a look at options for the United States to gain back leadership via a cooperative approach. The brief analyzes what nations could be effective partners for the United States in furthering nonproliferation while providing for the continued use of peaceful nuclear energy.
全球生物安全参与计划旨在防止使用生物剂和病原体的有害使用。鉴于滥用生命科学的尝试相对较少，因此很难衡量这些计划在改善生物安全方面的有效性。要了解如何进行生物安全参与和评估，Michelle Rozo博士约翰·霍普金斯大学（Johns Hopkins University）的候选人在美国和国外采访了35多名个人（包括政府官员及其非政府伴侣），涉及当前和将来的计划，这些计划可用于创建一种凝聚力，全球卫生系统的生物安全方法。
The 2011 accident at the Fukushima Daiichi nuclear power plant was preventable. The Great East Japan earthquake and the tsunami that followed it were unprecedented events in recent history, but they were not altogether unforeseeable.
A country with few natural resources, first Japan began to develop nuclear power technologies in 1954. Nuclear energy assisted with Japanese economic development and reconstruction post World War II. However, with the fear of lethal ash and radioactive fallout and the lingering effects from the 2011 accident at Fukushima-Daiichi Nuclear Power Plant, there are many concerns related to Japanese nonproliferation, security and nuclear policy.
The international responses to Iranian and North Korean proliferation bear many similarities, particularly in the use of economic sanctions as a central tool of policy. This issue brief contains an comparative analysis of U.S. policy toward Iran and North Korea.
The issue brief takes a deeper look at the nuclear policies of the Obama administration—polices that Dr. Norris terms “radical” with regard to their vision of a nuclear weapon free world.
A modified U.S. nuclear bomb currently under design will have improved military capabilities compared with older weapons and increase the targeting capability of NATO’s nuclear arsenal. The B61-12, the product of a planned 30-year life extension and consolidation of four existing versions of the B61 into one, will be equipped with a new guidance system to increase its accuracy.
While diplomats and officials claim Iran has slowed down its nuclear drive, new analysis shows that Iran’s enrichment capacity grew during 2010.
Since February 2010, Iran has been enriching uranium to concentrations of 20 percent U-235. A stockpile of 130 kg of 20 percent enriched uranium would reduce, by more than half, Iran’s time to develop a bomb. A key unknown is whether Tehran will stop the higher enrichment and, if so, under what circumstances.
The Nuclear Non-Proliferation Treaty (NPT) has endured as the cornerstone of the non-proliferation regime and remains the only legally binding multilateral agreement on nuclear disarmament.
President Obama’s deadline to address concerns about Tehran’s nuclear program passed at the end of 2009, so the White House is moving to harsher sanctions. But the U.S. is having trouble rallying the needed international support because Iranian intentions remain ambiguous.
