A Glimpse of the SILEX Uranium Enrichment Process
A relatively new technology for enriching uranium known as “Separation of Isotopes by Laser Excitation” or SILEX is described in some fresh detail in a recent Los Alamos paper (pdf).
SILEX, developed in 1992 by Australian scientists, is the rarest of birds in U.S. classification policy: It is privately generated information that is nevertheless classified by the U.S. government.
Ordinarily, information must be owned or controlled by the government in order to be eligible for classification in the first place. But under the peculiar terms of the Atomic Energy Act, the government may impose classification on “all” information concerning nuclear weapons and related matters that has not been previously declassified.
Since the new SILEX technology has never been declassified, it is ipso facto classified, despite the fact that it was generated by private (and foreign) researchers. It is the only known case in which the Atomic Energy Act has been used in this constitutionally questionable manner. (See Secrecy News, 06/26/01).
Unclassified details of the SILEX process, which uses pulsed lasers to selectively excite uranium hexafluoride molecules containing uranium-235, are presented in “Enrichment Separative Capacity for SILEX” by John L. Lyman, Los Alamos National Laboratory, LA-UR-05-3786 (thanks to WT).
The public rarely sees the quiet, often messy work that goes into creating, passing, and implementing a major piece of legislation like the CHIPS and Science Act.
If this proposed rule were enacted it would have deleterious effects on government workers in general and federal researchers and scientists, specifically.
When we introduce “at-will” employment to government employees, we also introduce the potential for environments where people are more concerned about self-preservation than service to others.
There is no better time to re-invigorate America’s innovation edge by investing in R&D to create and capture “industries of the future,” re-shoring capital and expertise, and working closely with allies to expand our capabilities while safeguarding those technologies that are critical to our security.
