RE: peer check, please Thanks Kenny.
Jerry, below is what we suggest you transmit to the NRC regarding Pa.
- Greg
An evaluation was performed to confirm that leakage test results based on the former Pa would still be expected to satisfy the appropriate acceptance criteria when tested at the new higher Pa. Basically, the leakage was scaled by a factor of 1.134 based on the relationship of the leakage rate to the square root of the pressure. A review of the testing results at GGNS demonstrates that substantial margin exists between the extrapolated results and the relevant acceptance criteria. All the increased leakage rates were found to comply with the current Tech Spec requirements that include margin to La. Thus, adequate margin is still available for the higher test pressure. A summary of key results from that presentation is presented below.
