Chemical Engineer with over 42 years of experience in nuclear reactors and materials, including a number of Senior Executive positions held at the NRC over 31-year tenure. Career at NRC encompassed all aspects of the agency’s regulatory duties including reactors and materials licensing, inspection, rulemaking, and emergency preparedness and response. Following the accident at Fukushima, led the NRC Near Term Task Force which provided recommendations to the Commission for “Enhancing Safety in the 21st Century”. Areas of expertise include:
- Organizational structure and staffing
- Reactor and materials licensing
- Emergency preparedness and response
- Inspector Qualification
- Consensus building
- Chairing and facilitating workshops
Principal Nuclear Safety Consultant providing management training and consultancies to developing countries as part of the International Nuclear Regulatory Partnership (IRDP). This has included developing and delivering training for regulatory authorities in Indonesia, Thailand, Jordan, South Africa, Kenya, Uganda, Jamaica, Honduras, Malaysia, Philippines, Romania, and other countries with emergent nuclear programs.
Mitigating Strategy submittals related to post Fukushima orders. Also participated as an expert providing advice to IAEA. Provided assistance to the USNRC in the review of the nuclear power industry’s programs on multiple occasions.
Developed guidance on how to review new reactor designs regarding mitigation strategies for loss of large areas of a nuclear plant. Reviewed and wrote the SERs for loss of large areas due to fires and explosions for the AP1000 design certification and the Vogtle 3 and 4 combined operation license application. As a member of the Executive Director of Operations special task force on Mitigation Strategies for Beyond Design Basis Terrorist Threats, developed guidance on evaluating the mitigation strategies and vulnerabilities of nuclear power plants due to aircraft impact and large explosions/fires. Reviewed and/or performed multiple PRAs including ABWR, CESSAR 80+, Millstone 1, Haddam Neck, Diablo Canyon, and Millstone 3. Performed risk-informed safety assessments of both license amendment requests and events at U.S. operating reactors. Managed the assessment of the risk associated with the SFP boiling at the Susquehanna nuclear power plant.
As a NRC PRA expert, identified plant weaknesses, which adversarial groups could potentially take advantage following the 9/11 attacks. Drafted significant portions of Safeguards Advisories and Orders issued by NRC following 9/11. Prepared and directed the development of technical bases for highly complex rulemakings. Resolved many licensing actions as Senior Project Manager for the Duane Arnold Energy Center. Provided technical and policy advice directly to the Commissioners on Diablo Canyon seismicity.
From 1976 to 1980 conducted engineering technical evaluations for various fuel cycle contracts for NRC, DOE, and EPA. Included were evaluations for heat transfer from spent nuclear fuel casks disposed in various geological media. During this period, supported DOD contract activity related to radiation protection and dose calculations from weapons testing in the 1950s.
Performed engineering technical evaluations for nuclear power plant design in areas of radioactive waste treatment and containment pressure and temperature limits.
