Uranium enrichment by lasers.

Enrichment Tails Assays and Uranium Supply: a Dynamic Relationship

At present, utility fuel buyers order uranium, conversion, and enrichment services according to optimization criteria based on relative prices for EUP inputs. Enrichment decisions are constrained only by enrichment contract requirements that limit the tails assays nominated to a certain range without surcharges. At present, given a uranium price of $33.75/kg U as UF6, and roughly $105/SWU, the ...

Minimization of waste from uranium purification, enrichment and fuel fabrication

FOREWORD As any industry, nuclear industry generates a diverse range of waste which has to be managed in a safe manner to be acceptable to the public and the environment. The cost of waste management, the risks to the public and employees, and the detriment to the environment are dependent on the quantity and radioactive content of the waste generated. Waste minimization is a necessary activity...

A Proliferation Assessment of Third Generation Laser Uranium Enrichment Technology

Low-resolution gamma-ray measurements of uranium enrichment.

We have developed smaller, lighter hardware (MCA and shielded detectors) that has been successfully transferred to the commercial sector. We have developed software that has received limited testing, the next release should be sufficiently robust for wide release to the general public. We have had initial success with more sophisticated analysis methods. We are pursuing medium-resolution tors a...

Uranium phosphate biomineralization by fungi.

Geoactive soil fungi were investigated for phosphatase-mediated uranium precipitation during growth on an organic phosphorus source. Aspergillus niger and Paecilomyces javanicus were grown on modified Czapek-Dox medium amended with glycerol 2-phosphate (G2P) as sole P source and uranium nitrate. Both organisms showed reduced growth on uranium-containing media but were able to extensively precip...
