Japan Crisis Not As Bad As Chernobyl
As Japanese authorities work to cool the nuclear reactors damaged by the earthquake and tsunami, it remains unclear how much radiation is being released into the environment.

As the crisis deepens at the Daiichi reactors in Fukushima, Japanese authorities are working to cool the reactors and limit the spread of radiation. The severity of the situation is both unclear and fluid, since measuring gauges at the Daiichi reactors are unreliable and radiation levels have fluctuated greatly on-site. Speaking on NBC’s Today Show, Carnegie’s James Acton describes the Fukushima reactor crisis as worse than Three Mile Island, though less disastrous than Chernobyl. During the Chernobyl catastrophe, Acton said, a significant fraction of the reactor core explosively spread into the environment. In Japan, the primary threat comes from the melting of the reactor core, exposing fuel rods to the atmosphere. The amount of radiation that will be released from such melting is unclear, Acton concluded.

It seems likely that, no matter what, the power of the U.S. nuclear arsenal will face erosion, not least in the credibility of its commitments to defend allies and the political durability of those alliances.

- President Lee Jae Myung: A Year in PowerCommentary
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.

- Taking the Pulse: Is European Diplomacy on Iran Outdated?Commentary
When the U.S.-Iran memorandum of understanding was announced, the UK, France, Germany, and Italy declared their readiness to help demine the Strait of Hormuz and lift nuclear sanctions on Tehran. But does Europe need new tools to recover a diplomatic role?

- Time for Nuclear Recycling? Prospects and Implications During a Global Nuclear Energy RenewalPaper
Nuclear recycling has emerged as a salient, cross-cutting issue, one that is heavily dependent on broader choices among reactor designs, fuel availability, economic resources, technological options, and political choices. States and nuclear industries seeking to advance recycling must devote sustained consideration now to the interplay of all these factors.
