The mission of the U.S. Department of Energy (DOE), Office of Nuclear Energy is to advance nuclear power in order to meet the nation's energy, environmental, and energy security needs. Advanced high temperature reactor systems will required compact heat exchangers (CHX) for the next generation of nuclear reactors. The DOE is sponsoring research to support the development and deployment of CHXs for use in high temperature advanced reactors. The project is being executed by an Integrated Research Project (IRP) that includes university research institutes, national laboratories, manufacturers, and industry experts.
The objective is to enable the use of compact heat exchanger designs in advanced reactor service. A necessary step for achieving this objective is to ensure that the ASME Boiler and Pressure Vessel Code, Section III, Division 5 has rules for the construction of CHXs for nuclear service. However, construction rules alone are not sufficient to deploy a compact heat exchanger in an advanced reactor. A strategy for ASME Section XI, Inservice Inspection (ISI) of a heat exchanger in an operating nuclear reactor will also be required.
The purpose of this ASME Code Roadmap is to identify the research gaps impeding the development of suitable construction and inservice inspection rules for compact heat exchangers for high temperature reactor service and to provide a framework to utilize the research project results consistent with the expectations and needs of the industry and future owners.
