| Title | Failure to Ensure a Flow Path for Containment Spray Pumps |
| Description | The inspectors identified a non-cited violation of Technical Specification 5.4.1.a for failure to implement Procedure OPT-435B. This resulted in the Unit 2 Train B containment spray pumps recirculation valves being closed when they were required to be open during pump operations to support testing. The licensee entered this violation into their corrective action program. The finding is greater than minor because it could be viewed as a precursor to a significant event, in that, not implementing the prerequistes prior to performing test on other safety-related pumps could lead to significant damage. Unique features of the containment spray system design prevented damage to the pumps. The same failure to ensure a flow path for other safety-related pumps would have resulted in significant damage. The violation is associated with the Barrier Integrity cornerstone attribute of structure, system, and component reliability. Since Unit 2 was in Mode 6 on residual heat removal cooling, Appendix G of Manual Chapter 0609 applied and Checklist 4 determined this to be of very low safety significance. The cause of this violation is related to the human performance crosscutting component of Work Practices in that operations management failed to effectively communicate expectations regarding procedural requirements and operations personnel failed to follow procedures H4.b |
