The Centralized Reliability Data Organization (CREDO): Past, present, and future
the Centralized Reliability Data Organization (CREDO) is a component-based data system and data analysis center jointly sponsored by DOE and the Power Reactor and Nuclear Fuel Development Corporation (PNC) of Japan. Efforts within CREDO are focused on reliability, availability, and maintainability (RAM) data and analyses for mechanical, electrical, and electronic components that were designed to function in liquid metal environments and their support systems. Data are currently received from a variety of sources, including DOE facilities and PNC facilities at 0-arai Engineering Center. Engineering, event, and operating data records are submitted by site staff for inclusion into the CREDO database. Engineering records provide detailed information on component design and operating parameters, abnormal or unusual occurrences are documented in the event reports, and facility operating status is provided in the operating report. Event rates on individual components or subpopulations may be calculated. In addition to data collection, CREDO staff disseminate RAM data and publish analyses of their findings. Results from two recent analyses are summarized: a journal article on large sodium circulation pumps and a paper on motor-operated globe valve performance. Funding for continued data collection has not been committed for FY1 993. A proposal to shift the CREDO database management system from a mainframe computer to a PC-based system has been supported by DOE. Under this proposal, the entire contents of the database will be distributed directly to approved members of the LMR community.
