Will Japan Try to Save the INF Treaty?

, China project manager and senior analyst

US President Ronald Reagan and Japanese Prime Minister Yasuhiro Nakasone meet at Camp David in 1986.

President Trump said he plans to withdraw from the Intermediate Nuclear Forces (INF) Treaty. US National Security Advisor John Bolton implied the government of Japan already agreed.

Not long after Bolton’s statement, Foreign Minister Taro Kono told reporters the Abe government needed to discuss the fate of the treaty with US officials before commenting. Six days later US Deputy Assistant Secretary of State for Arms Control Tom DiNanno and Deputy Assistant Secretary for East Asia Marc Knapper arrived in Tokyo for a three-day dialog on US extended deterrence guarantees for Japan. The fate of the INF treaty was on their agenda. What did Japanese officials tell the Trump administration? Read more >

Nuclear Reactor Fuel Safety: The Waiting Gain

, former director, Nuclear Safety Project

Nuclear power reactors spilt atoms to release energy used to generate electricity. Many of the byproducts formed when atoms split are unstable (radioactive) and release particles or gamma rays in search of stability. These radioactive emissions produce energy. Whether in the core of an operating reactor, in the core of a shutdown reactor, in the spent fuel pool after discharge from a reactor core, or in dry storage after offloading from a spent fuel pool, the energy released from nuclear reactor fuel must be removed before it damages the fuel from overheating. This commentary describes the energy levels associated with nuclear fuel in various locations at various times to illustrate the factors that affect the associated hazard levels. Read more >

No, Space-Based Missile Defense Will Not Cost Only $20 Billion. (Spoiler: That’s only the launch costs.)

, senior scientist

Space-based missile defense is a terrible idea. It is expensive and straightforwardly defeated, and it is dangerous and destabilizing. (If you haven’t watched it, please do take a look at this video and web feature UCS just produced. It helps to see these arguments visually.)

But knowledgeable people say it’s not so expensive!

At a recent event hosted by the Missile Defense Advocacy, Under Secretary of Defense for Research and Engineering Mike Griffin calculated the cost to “put up” an interceptor layer. Given how Griffin talked about it, you may be forgiven for thinking he means this is the full cost of a space-based missile defense system—rather than just the cost of launching the interceptors into space.

Fatal Accident at Arkansas Nuclear One

 Role of Regulation in Nuclear Plant Safety #11

The Fatal Accident

As described in Fission Stories #139 and illustrated in Fission Stories #181, a temporary crane removing a component weighing 525 tons on March 31, 2013, in the turbine building of the Unit 1 reactor at Arkansas Nuclear One near Russellville, AR collapsed. The dropped load struck the turbine building floor with considerable force, then rolled and fell through an opening to cause further damage on a lower floor. One worker was killed and eight others injured by the accident. Read more >
