155149 - A New Asme Standard: Plant Systems Design 

Abstract: 

The draft ASME Plant Systems Design standard (PSD-1) provides a new approach to design of nuclear and other plants with potential for significant hazards to the health and safety of the public, the worker, and the environment. The objectives of PSD-1 are to improve integration of health, safety, and environmental risk evaluations with design; reduce new plant design, construction, commissioning, and life cycle costs; reduce licensing and construction uncertainty; and improve operating plant availability. PSD-1 includes requirements and guidance, for design organizations to incorporate risk informed probabilistic design methodologies with traditional deterministic design methods using reliability and availability targets. It integrates systems engineering, qualitative and quantitative risk evaluations, and probabilistic design methods into traditional design processes. The risk evaluation processes integrate safety risk evaluations with production risk evaluations to increase performance over the plant life cycle. Risk evaluation processes also integrate current industry and regulatory concepts of defense-in-depth, safety significance, as well as risk-informed and performance-based design into a seamless design process. The PSD committee follows a systems engineering process and is writing the standard in a Model Based Systems Engineering tool. This paper provides an introduction and overview of the new standard that is targeted for publication in 2025.

Presenting Author Biography: Ralph S Hill III retired as a Westinghouse Electric Company, Consulting Engineer in 2014 and formed his own company, Hill Eng Solutions LLC. He has over forty-five years of technical and management experience including more than thirty-five years in planning, engineering design, construction, and modification for the nuclear power industry. In the fourteen years prior to Westinghouse, he provided strategic planning, system engineering, risk management, process evaluation, and project management consulting services to the U.S. Department of Energy in spent nuclear fuel, radioactive waste management, and nuclear materials disposition-related projects.
Ralph has been actively involved as a contributor and a leader in promulgation of ASME nuclear codes and standards for over 40 years and has been awarded the Melvin R. Green codes and Standards Medal, the Bernard F. Langer Nuclear Codes and Standards Award, the Codes and Standards Distinguished Service Award, and the grade of ASME Fellow. He is past Vice-Chair of the ASME Council on Standards and Certification, past Chair of the ASME Board on Nuclear Codes and Standards, and past Chair of the Boiler and Pressure Code, Section III, Nuclear Construction Standards Committee.
Although retired, Ralph continues his volunteer activities in support of ASME codes and standards. Currently Ralph serves as a an Ex-Officio Member of the Board on Nuclear Codes and Standards, and as both champion and Chair of the Standards Committee on Plant Systems Design.
