Paschal Solutions, Incorporated is a woman-owned small business established in 1999.  PSI was initially established as a nuclear criticality safety (NCS) engineering consulting firm, which continues to be the primary focus of our staff.  In addition to NCS, design and analysis in the areas of heat transfer, instrumentation and control, vibration and shaft alignment, and laser physics are all part of our engineer talent base.  We have increasingly offered our clients a diverse engineering skill-set that can be applied to virtually any industrial challenge.

Philosophy

Paschal Solutions, Inc. provides world-class engineering solutions that enhance safety by continually striving to improve process efficiency.  We recognize the safest way to operate is often the simplest and most efficient way to operate.  In this way, safety becomes part of the fabric of efficient cost-effective operation, rather than being a costly obstacle.

Nuclear Criticality Safety Consulting

PSI has provided Nuclear Criticality consulting services for a wide range of clients including: 

• United States Enrichment Corporation (USEC)
• Nuclear Fuel Services (NFS)
• Babcock and Wilcox Technologies (BWXT)

We have unmatched expertise related to UF₆ and its byproducts.  PSI engineers have extensive experience with the unique challenges of the physico-chemical nature of these systems, having provided analysis of every fissile system related to the gaseous diffusion plant process.   

Our experience base also includes extensive analyses of uranyl nitrate systems and uranium metal systems.  Respected and active in the NCS community, we have the experience and flexibility to bring the right resources to bear on any NCS challenge.
 

Engineering

PSI brings a “can-do” attitude to problem solving.  In addition to NCS, we have provided engineering services in the areas of heat transfer, rotating equipment and vibration analysis, instrumentation/control, operational engineering, and laser system design control and analysis.  Our engineering experience base includes:

•     Reactor Engineering: (including typical core follow activities, refuel activities and particular experience in the area of neutron noise analysis for predictive performance)

•     Core design for commercial nuclear facilities

•     Mechanical engineering particularly related to heat transfer systems (including development of new and novel systems for cryogenic cold trapping and chemical separation)

•     Instrumentation and control (e.g. development of movable incore detection control system)

•     LabView™:  We have extensive experience in LabView™ programming for FFT noise analysis and PC-based process control.

 We have experience in:

•     molecular lasers operation and design,

•     operation of laser diode systems,

•     operation and design of electro-optic components such as modulators and Pockels cells,

•     developing precise timing and control for complex laser processes,

•     designing and building heat exchangers.
