Mr. Short has over 30 years of experience supporting U.S. Department of Energy (DOE), Nuclear Regulatory Commission (NRC), and national/international clients in nuclear facility safety and risk analysis, nuclear facility decommissioning planning and analysis, project risk analysis and management, and used nuclear fuel and high-level radioactive waste assessment. He is a nuclear engineer by academic background, with a Master of Business Administration degree, whose career has focused on development and application of analytical methods, tools, and techniques to support project and investment decisions. Mr. Short’s current project interests include providing NRC with technical evaluations of risk-informed applications by nuclear power plant licensees, providing project risk management and analysis to the National Nuclear Security Administration (NNSA), providing technical and economic assessments of small modular nuclear reactor applications for international clients, and providing technical support to NRC on nuclear facility decommissioning funding matters. He is a registered professional engineer in the state of Washington.
