“…In recent years there have been numerous independent efforts within the DOE national laboratories to gather and analyze sodium component reliability data, but these efforts have had limited success without access to CREDO-I. An Idaho National Laboratory (INL) paper reviewed the various sources, including published CREDO documents, to bound failure rates for liquid metal cooling system components [18] but did not have access to engineering records. An effort at Pacific Northwest National Laboratory (PNNL) sought to locate the FFTF CREDO input forms in order to recreate a portion of the database for use in developing a time-dependent reliability evaluation methodology [19], but PNNL was not able to recover enough information to create a database.…”

This report was written as part of a United States Department of Energy (DOE), Office of Nuclear Energy, Advanced Reactor Technologies program funded project to recreate the capabilities of the legacy Centralized Reliability Database Organization (CREDO) database. The CREDO database provided a record of component design and performance documentation across various systems that used sodium as a working fluid. Regaining this capability will allow the DOE complex and the domestic sodium reactor industry to better understand how previous systems were designed and built for use in improving the design and operations of future loops. The contents of this report include: overview of the current state of domestic sodium reliability databases; summary of the ongoing effort to improve, understand, and process the CREDO information; summary of the initial efforts to develop a unified sodium reliability database called the Sodium System Component Reliability Database (NaSCoRD); and explain both how potential users can access the domestic sodium reliability databases and the type of information that can be accessed from these databases. and the sodium reactor engineering support of Andrew Clark (8851) and Natalie Gordon (8853). A special thank you is extended to Dusty Brooks (8853), Vincent Mousseau (8852), Charles Andraka (8823), and Timothy Wheeler (8851) for their technical review of this report. The authors would also like to thank David Grabaskas and Matthew Bucknor from Argonne National Laboratory for their help in locating documents associated with the original CREDO database. Additionally, the responsive and helpful team at OSTI, specifically Brownyn Bunch, have assisted greatly in the knowledge management and preservation aspects of this project. v vi UOR Unusual Occurrence Report
