| Title | Mode Change Under Technical Specification 3.0.4.b Without Required Risk Management Actions |
| Description | On November 18, 2009, the inspectors identified a noncited violation of Technical Specification 3.0.4.b for ascension from Mode 4 to Mode 3 without establishing required risk management actions. Wolf Creek used technical specification Limiting Condition for Operation 3.0.4.b to permit mode ascension after performance of a risk assessment and identification of risk management actions to maintain safety in the next mode. The turbine-driven auxiliary feedwater pump was inoperable per Technical Specification 3.7.5. As a risk management action, protected train signs would be placed on the doors to the motor-driven auxiliary feedwater Pump A and B room doors. A walkdown conducted by the inspector on the morning of November 18, 2009, found that the protected train signs on the motor-driven auxiliary feedwater pump rooms were not in place. Also, a maintenance crew was performing radiography in the motor-driven auxiliary feedwater pump Room B. The motor-driven auxiliary feedwater Pumps A and B were also made inoperable (at separate times) later on the morning of November 18, 2009. The licensee entered this issue in their corrective action program as Condition Report 21926. Mode ascension under Technical Specification LCO 3.0.4.b without establishing required risk management actions is a performance deficiency. The finding was more than minor because it was associated with the configuration control and alignment attribute of the Mitigating Systems Cornerstone and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The configuration control issues not only included the work being completed on the turbine-driven auxiliary feedwater pump, but also included containment isolation valve testing and radiography that was performed on the motor-driven auxiliary feedwater pumps which was not included in the risk assessment. The inspector used Inspection Manual Chapter 0609.04, to determine that the finding was of very-low safety significance (Green) because it did not result in a loss of system safety function; did not exceed allowable technical specification outage time; and was not a seismic, flooding, or severe weather concern. Additionally, the cause of the finding has a human performance crosscutting aspect in the area associated with decision making. Specifically, Wolf Creek used a risk assessment form and an informal mode change form to communicate between departments the requirement for risk management actions. The two forms were in conflict and the personnel who implemented the risk management actions were not informed H.1(c) (Section 1R13) |
