Associated with each component of a Nuclear Steam Supply System are the necessary supporting documents which demonstrate compliance with applicable codes, specifications and design criteria. The documents are grouped into individual data packages, and may exceed 800 in number for a major installation. A complete review, initiated by a utility in response to federal code regulations (10 CFR 50), can involve a tremendous number of review transactions. A data management system to assist the reviewer in the tracking and resolution of discrepancy items is curently under development and use. The system uses microcomputer-based relational database management software and provides complete and flexible capabilities to process database components and attributes based on user specified criteria. The completed database is a portable system, and can be utilized on an as-needed basis after the review is completed. A discrepancy analysis is performed to identify relations between manufacturer and discrepancy occurrence, part type vs. discrepancy type, etc. These results may prove useful in subsequent reviews or application to existing QA procedures.
