Radiation Concerns Near Fukushima

As power is being restored to the Fukushima nuclear reactors, which were severely damaged by Japan's recent earthquake and tsunami, crucial questions remain about whether the cooling system will be functional and the likelihood of further radiation leaks.

Nuclear Policy

The Nuclear Policy Program aims to reduce the risk of nuclear war. Our experts diagnose acute risks stemming from technical and geopolitical developments, generate pragmatic solutions, and use our global network to advance risk-reduction policies. Our work covers deterrence, disarmament, arms control, nonproliferation, and nuclear energy.

While conditions have substantially improved at Fukushima’s Daiichi reactors, which were damaged by Japan’s recent earthquake and tsunami, crucial questions and dangers persist. As power is being restored to the nuclear reactors, it remains unclear if the cooling pumps, needed to prevent overheating in the reactor cores, have become unusable. Some have begun arguing that it is time to entomb the reactors in concrete to prevent further radiation leaks, effectively abandoning the reactors, but in an interview with CBS’ Early Show, Carnegie’s James Acton argued that there is still time to stabilize and finish the cooling process. The dangers at the Fukushima plants are serious, but have receded, Acton said, although there is the potential for further degradation of nuclear materials. In particular, reactor unit three has been emitting smoke inexplicably, which is causing increasing concern. Nonetheless, Acton expressed cautious optimistic about progress at the reactor site.

    China’s Energy Security Doesn’t Run Through Hormuz but Through the Electrification of Everything

    Across Asia, China is better positioned to withstand energy shocks from the fallout of the Iran war. Its abundant coal capacity can ensure stability in the near term. Yet at the same time, the country’s energy transition away from coal will make it even less vulnerable during the next shock.

    Japan’s Security Policy Is Still Caught Between the Alliance and Domestic Reality

    Japan’s response to U.S. pressure over Hormuz highlights a broader dilemma: How to preserve the alliance while remaining bound by legal limits, public opinion, and an Asia-centered security agenda. Tokyo gained diplomatic space through an alliance-embracing strategy, but only under conditions that may not endure.
