Description
Current design basis calculations indicate … Current design basis calculations indicate the high pressure safety injection (HPSI) pumps could potentially operate in a run-out condition under certain worst case design basis conditions. The calculated flow is beyond the pump curves. The HPSI pumps could operate in a run-out condition for an extended period following a design basis accident. The pump vendor indicates that long term operation in this condition could not be supported due to accelerated wear of pump internal components. This represents a reportable unanalyzed condition.</br>The NRC Resident Inspector has been notified. NRC Resident Inspector has been notified.  +
