FOR NOT CONDUCTING A TEAIM INSPECTION PER MD 8.3 PLANT - Salem, Unit 1 EVENT DATE - 5/28/04 BRIEF DESCRIPTION OF SIGNIFICANT OPERATIONAL EVENT - 1 SW26 Inoperable in Mode 3 and Higher EVAL DATE - OEVl 0/04 Deterministic Criteria
- a. Involved operations that exceeded, or were not Included in, the design bases of the facility.
Remarks: Only one train affected
- b. Involved a major deficiency in design, construction, or operation having potential generic safety implications.
Remarks: repetitive valve maintenance issues have surfaced over recent months, however, the number of failures and the low risk associated with them do not constitute a major deficiency.
- c. Led to a significant loss of integrity of the fuel, the primary coolant pressure boundary, or the primary containment boundary of a nuclear reactor. (Significant loss applies to each boundary)
Remarks: Only one train affected
- d. Led to the loss of a safety function or multiple failures in systems used to mitigate an actual event.
(An event has occurred and a safety-function or mitigation system has actually failedO Remarks: Only one train affected
- e. Involved possible adverse generic implications.
Remarks:
N/A
- f. Involved significant unexpected system interactions.
Remarks: Nothing unexpected
- g. Involved repetitive failures or events involving safety-related equipment or deficiencies in operations.
Remarks: there were a number of MOV issues during recent RFO or repetitive MOV issues in past.
- h. Involved questions or concerns pertaining to licensee operational performance.
Remarks:
N/A
- x. Involved one or more of the radiological or materials criterion provided in MD 8.3 Guidance.
