NSUF 24-Zion: Harvested Reactor Pressure Vessel Material from Zion Unit 1

The decommissioning of the Zion Units 1 and 2 Nuclear Generating Station in Zion Illinois presented a special and timely opportunity for developing a better understanding of materials degradation and other issues associated with extending the lifetime of existing nuclear power plants (NPPs) beyond 60 years of service. In support of extended service and current operations of the US nuclear reactor fleet, ORNL, through the Department of Energy (DOE), Light Water Reactor Sustainability (LWRS) Program, coordinated and contracted with Zion Solutions, LLC, to acquire materials from Zion to evaluate potential materials degradation issues associated with extended lifetime of existing nuclear power plants.

The LWRS Program and other organizations acquired materials from the Zion Unit 1 reactor pressure vessel (RPV) containing well-characterized base metal heat B7835-1 and a section of the well-characterized WF-70 beltline weld (between the lower and the intermediate shells). The harvested material was cut into blocks for machining into mechanical test specimens and microstructural characterization samples. A portion of the A533B test specimens have been donated from the DOE LWRS Program to the NSUF Program to be listed in NFML and made available for nuclear energy research.
