| Title | Failure to Provide an Adequate procedure to Control Essential Spray Pond Missile Hazards |
| Description | The inspectors identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion V, \"Instructions, Procedures and Drawings,\" for the failure of engineering personnel to establish adequate procedures to ensure evaluation and approval of transient missile structure hazards that have an effect on the operability of the essential spray ponds. Specifically, since January 15, 1997, civil engineering personnel failed to develop an adequate procedure to verify missile density criteria are not exceeded to ensure operability of the essential spray ponds during severe weather. This resulted in approximately 40 transient missile hazards being placed around Unit 1 spray Pond A without an approval or evaluation to ensure continued operability of the essential spray ponds. The licensee determined the spray pond was operable following a walkdown and evaluation of the missile hazards. This issue was entered into the licensee\'s corrective action program as Condition Report/Disposition Request 3224028. The finding is greater than minor because it is associated with the external factors attribute of the mitigating systems cornerstone and affects the cornerstone objective of ensuring the reliability of systems that respond to initiating events to prevent undesirable consequences. Using Manual Chapter 0609.04, \"Phase 1 Initial Screening and Characterization of Findings,\" the finding was determined to have a very low safety significance because the finding did not result in a loss of system safety function, an actual loss of safety function of a single train for greater than its technical specification allowed outage time, or screen as potentially risk-significant due to a seismic, flooding, or severe weather initiating event. This finding has a crosscutting aspect in the area of problem identification and resolution associated with the corrective action program because appropriate corrective actions were not taken to address safety issues and adverse trends in a timely manner, commensurate with their safety significance and complexity P.1(d) (Section 1R13). |
