I have over a decade of experience consulting in the fields of nuclear criticality safety (NCS), non-destructive assay (NDA), radioactive waste management, safety and compliance reviews, audits, and reactor physics. My expertise includes nuclear criticality safety and non-destructive assay support to five challenging and complex decommissioning projects. The remediation projects have involved the exhumation, assay, treatment and packaging of large volumes of legacy buried waste materials from large-scale burial pits, linear trenches, standpipes, and bunkers. The gaseous diffusion plant D&D includes development and implementation of systematic approaches for measurement of miles of process gas piping, and the development of the Criticality Incredible strategy or demolition and subsequent burial of process buildings. My duties on these projects included regular interfacing with the regulator, including participation in the USACE incident investigation and emergency response preparedness for SLDA. I am offering my services as a nuclear safety expert witness.
