A Different Time

After the Soviet Union broke up in 1991, the directors of the nuclear weapons laboratories on both sides quickly got together to work on securing nuclear weapons and the materials they are made from. They were supported by their governments. NATO helped. The cooperation was a marvelous thing to see and to experience. I had a small part in dealing with leftover Soviet nuclear problems.

In 1998, I traveled to Estonia to help deal with a former Soviet uranium-processing plant. I’ve written up my experience. Siegfried Hecker, the director of the Los Alamos National Laboratory and a primary mover in the lab-to-lab cooperation, has collected the experiences of many participants in a two-volume set, Doomed to Cooperate. He has also set up a website for more information, which is where my story appears.

Check it out. The top photos are mine, of one part of the site in 1998 and in 2011.

Tunnel Collapse at Hanford

A tunnel collapsed in the 200 Area of Washington State’s Hanford Reservation. The 200 Area is where fuel elements from Hanford’s reactors were processed to recover the plutonium that went into American nuclear weapons. I was not aware of an underground rail system there. The system is probably in the 200 area only because the reactors are much too far away to make an underground system possible. Read More

How I Learned To Love Climate Modeling

I’m annoyed by the New York Times hire of Bret Stephens, more annoyed by the defense that Times editors are mounting on Twitter. I’m annoyed that this has to be said again, but here we are, as Times editors tell us that any criticism is merely trying to silence a conservative voice. My objections have nothing to do with Stephens’s political views, except that it is clear that those views drive his views of climate change.

I was once a climate skeptic, with a great deal more basis than Stephens’s sense that life is uncertain and therefore we should eat dessert first. My skepticism arose BECAUSE I knew something about the climate models. Read More

Iodine-131 Over Europe: Probably Medical

In early January, slightly elevated levels of iodine-131 were observed over northern and western Europe. The levels were measured during a temperature inversion, along with elevated levels of naturally occurring radioisotopes.

This, along with the deployment of an American WC-135 aircraft to the Mildenhall Royal Air Force Base in the UK, has led to speculation that the Russians have carried out a nuclear test. This is highly unlikely for several reasons. Read More
