Vermont Yankee PIs / Findings (CY 2007)

  • All Green Performance Indicators
  • 7 Green / Severity Level - IV inspection findings 17

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

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 19

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 20
