Reactor Vessel Integrity Database Version 2.0.1

On this page:


The Reactor Vessel Integrity Database (RVID) was a DOS-based application developed using FoxPro ™ software. The database was enhanced, and was released as Version 2 (RVID 2), a Windows 3.1 native application based on Microsoft Access 2.0 ™. The database is now available in Microsoft Excel TM format.

The RVID 2 summarizes the properties of reactor vessel beltline materials for each operating U.S. commercial nuclear power plant. For plants that are not operating, existing data has been maintained (i.e., no existing data for non-operating plants has been deleted). The RVID was designed and developed to reflect the current status of reactor pressure vessel integrity, and the data and information are consolidated in a convenient and accessible manner. Some of the data categories are inputs of docketed information; other data categories are computed values, which are not necessarily docketed. The programming logic used for calculations in the RVID 2 follows the methodology in Regulatory Guide 1.99, Revision 2. The data and information provided by licensees' in their responses to the staff's Generic Letter (GL) 92-01, Revision 1 close-out letters, and in response to GL 92-01, Revision 1, Supplement 1, are included in Version 2 of the RVID. This database includes updates from June 1999 - July 2000.

Consistent with our Open Government Plan, the NRC has issued a high-value dataset (with accompanying data dictionary) to expand the public’s knowledge about the agency’s oversight of operating reactor facilities, as it relates to embrittlement of reactor pressure vessel materials. Irradiation embrittlement is a phenomenon that occurs as a consequence of reactor operation when neutrons from the nuclear fuel irradiate the thick steel plates and welds used to construct the vessel. This irradiation embrittles the steel, making it less tough and, therefore, less capable of maintaining structural integrity in the presence of flaws that may exist following fabrication. (For additional detail, see the Fact Sheet on Reactor Pressure Vessel Issues.) The NRC obtains information on irradiation embrittlement from surveillance capsule reports obtained through the Reactor Vessel Material Surveillance Program conducted under Appendix H to Title 10, Part 50, of the Code of Federal Regulations (10 CFR Part 50). Information from these surveillance capsule reports is summarized in the RVID 2, along with information from other sources.

Available in open format (Microsoft Excel), this Reactor Materials Embrittlement Dataset provides access to information on surveillance capsule reports, which include reactor materials embrittlement data from the Nation’s fleet of operating nuclear power reactors. Specifically, this dataset lists each plant name and reactor type, designer, and manufacturer. It also states the plant’s license term, the date on which the operating license will expire, and whether the plant was licensed to operate as of January 1, 2011. In addition, the dataset provides the PDF filename for the plant’s surveillance capsule report, along with the report date and identification of the specific surveillance capsule. The related Data Dictionary explains each field in the dataset and provides instructions for accessing the surveillance capsule reports.
