ENCLOSURE SEQUOYAH NUCLEAR PLANT UNIT 2 RETRIEVABLE INFORMATION FROM VALVE TAG NUMBERS SQRD-50-328/81-05 10 CFR 50.55(e)
FOURTH INTERIM REPORT Description of Deficiency Manufacturer's valve drawings which include pertinent engineering data used in piping analysis and other design calculations cannot be readily retrieved through any TVA documentation system as required by 10CFR50, Appendix B.
Proper identification of valves should be maintained by part number, serial number, or other appropriate means on the valve bodies and cross-referenced on all associated drawings and permanent records. This identification is used for the retrieval of records and is designed to prevent the use of incorrect parts and components in piping systems.
Interim Progress TVA is developing a cross-reference list on valve drawings so that information can be more readily retrieved through any TVA documentation system. This deficiency involves only the ease of information retrieval from appropriate documentation systems and will not affect power operations.
