China and MIRVed Warheads

A recent Pentagon report on Chinese Military Power reported that for the first time China has apparently begun to put multiple warheads on some of its ballistic missiles. This would mean that China can use its existing missile force to launch more nuclear warheads. This change was also reported in a New York Times article over the weekend. Read More

China’s January 2013 Missile Defense Test

Some of the best sleuthing and analysis these days is being done by the group at the Center for Nonproliferation Studies in Monterey at the Middlebury Institute of International Studies. So when Catherine Dill and Jeffrey Lewis emailed me to help fit a few pieces together I was happy to help.

They have been piecing together information about China’s Korla Missile Test Complex, which appears to be the base where China has launched interceptors for several recent missile defense tests. They are posting their analysis today at armscontrolwonk. Read More

No More Ft. Calhouns!

The nuclear accident at Fukushima, Japan in March 2011, which resulted in the meltdown of three reactors and the release of huge amounts of radiation, led to intense study of the causes of the accident and the catchphrase “No more Fukushimas!”

Last week, Dave Lochbaum released a report that looks in detail at an event that occurred around the same time but garnered much less attention and scrutiny—the shutdown of the Ft. Calhoun reactor in Nebraska for what turned out to be a two and a half year outage to make extensive repairs. Problems at the plant had been missed by inspections for years and accumulated to the point that such a long outage was needed to fix them. Read More

The NRC and the Value of Life—Revisited

In February 2011, my colleague Ed Lyman wrote a blog post and a letter to the New York Times pointing out that the Nuclear Regulatory Commission (NRC) assigns a MUCH lower value to human life when assessing the costs of accidents than other government agencies. This issue has been raised again in a recent Bloomberg article. Read More

China announced that the launch was part of a project to study space weather and that the probe carried out an experiment at high altitude. A report in China News (translation) stated that the launch reached an altitude of about 10,000 km. Read More
