Pivotal Moment in Japan?

Much remains unknown as Japan attempts to cool the nuclear reactors and spent fuel rods at its damaged Fukushima nuclear plant, including whether restoring electricity to the cooling systems will help prevent the crisis from growing.

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.

KATIE COURIC, CBS: James Acton with the Carnegie Endowment for International Peace is a physicist and an expert on nuclear safety. James, Japanese officials acknowledged what U.S. officials said yesterday, those spent fuel rods, more than 11,000 of them in rapidly evaporating pools are the real danger. Why initially were there two different assessments of the situation?

JAMES ACTON, Carnegie Endowment for International Peace: In many ways I think there probably still are two different assessments of the situation. There`s no question that the evaporating fuel pools is serious. Without all of that water as shielding, this site is going to become much more heavily irradiated and consequently harder to move around and work it. But I think there`s a genuine disagreement here over the chances that without the cooling effect of water these fuel rods could ignite. And there`s a disagreement over how risky that is compared to the consequences of a meltdown.

COURIC: Are helicopters and water hoses really the best solution to this crisis?

ACTON: Probably yes is the answer to that one. We’re far beyond the playbook on this. There`s no manual, there`s no emergency equipment, to deal with this kind of extreme situation. So right now the Japanese government are being forced to improvise.

COURIC: If the power comes on, will that solve the problem?

ACTON: I don`t know, but this is going to be a pivotal moment when the power comes on because if the cooling systems in the reactors and fuel ponds are basically sound and then the power comes on, then that -- We might look at that moment as the beginning of the end of this crisis. If, however, the cooling systems are damaged and the power comes on, they might not function correctly and this crisis could continue.

COURIC: James Acton of the Carnegie Endowment. Thank you.

ACTON: Thank you, Katie.

    Demystifying the Nuclear Threshold

    The nuclear weapons threshold is increasingly important for proliferation strategy and policy. Policymakers should better understand the implications of the threshold phenomenon in the current international security environment and plausible strategies to deal with the growing challenge that it presents.

    President Lee Jae Myung: A Year in Power

    President Lee marked his first year in office after one of the most tumultuous periods in South Korean politics. Though Lee has enjoyed a high approval rating, a large majority in the National Assembly, and foreign policy victories, Lee and his party’s political fortunes depend on generating economic growth, learning the right lessons from the recent local elections, and managing contentious factional strife within his political base.
