Alex Glaser and Scott Kemp (above) gave a talk on Gas Centrifuges and the future of nonproliferation at Tsinghua University, with Li Bin as host.
The talk was cool, but the diagram of the centrifuge is HOT, supplanting the very excellent diagram that Jandos Rothstein created for the Bulletin of Atomic Scientists.
Li Bin and Alex Glaser are both involved with the International Panel on Fissile Materials, which just released the IPFM Global Fissile Material Report 2006.
