Condensation Repression Isotope Selective Laser Activation (CRISLA)
A demonstrated US-origin laser enrichment technology that is scalable, efficient and cost competitive.
- Conceptualized and patented by pioneer and father of Laser Enrichment – Jeff Eerkens, Ph.D
- Experimentally demonstrated on several occasions (80’s and 90’s) up to LEU level
- Technology avoids many of the scaling issues of other Laser Enrichment schemes
- LIS Technologies is a USA based company, which opens additional opportunities (i.e. fuel for US Navy fleet, HALEU fuel for Small Modular Reactors (SMRs), chemical extraction of Mo-99 from MOX fuels, medical isotopes, etc.)
The Laser Enrichment Process – 3 Steps
Step 1: Preparing the UF6
Step 2: Selective Excitation
Step 3: Product Harvesting
Patented Technology
Process and Apparatus for Condensation Repression Isotope Selective Laser Activation
Key Features:
The CRISLA technology has several advantages over diffusion, centrifuge and/or other laser enrichment processes:
- Selective excitation of the 3ʋ3 vibrational mode of 235UF6
- Simplified architecture due to low absorption and shorter wavelength
- Lowest comparative enrichment costs with high efficiency
and throughput - Avoids the issues found in legacy pulsed 16µm CO2 lasers
- Flexible in feed and/or product assay, optimized for LEU or HALEU fuel
