17 Vermont Yankee PIs / Findings (CY 2007)
- All Green Performance Indicators
- 7 Green / Severity Level - IV inspection findings
18 NRC Inspection Findings Vermont Yankee
- Error made by electrical maintenance department technicians resulted in the need for a reactor power reduction
- Inadequate design control associated with condensate storage tank vortex analysis
- Failure to follow procedure resulted in an unplanned emergency diesel generator shutdown and unavailability
19 NRC Inspection Findings Vermont Yankee
- Failure to establish minimum thread engagement for a packing gland stud resulted in unplanned unavailability of a service water pump
- Contract radiation protection technician allowed an operator to enter a locked high radiation area without first performing a survey of the area
20 NRC Inspection Findings Vermont Yankee
- Reactor scram during troubleshooting due to inadequate preventive maintenance on a main turbine stop valve
- Inadequate inspection program resulted in the partial collapse of a non-safety related cooling tower cell
21 NRC Annual Assessment Summary Vermont Yankee
