Dear Mr. Grier:
In accordance with Appendix A, Beaver Valley Technical Specifications, Licensee Event Report LER 80-075/0lP, Technical Specification 6.9.1.8, ,
Administrative Controls, is submitted. This occurrence was reported to j
- Mr. J. Hegner, the Beaver Valley Resident Inspector, at 0920 hours0.0106 days <br />0.256 hours <br />0.00152 weeks <br />3.5006e-4 months <br /> on l October 8, 1980.
Evaluation and reanalysis required by IE Bulletin 79-14 have shown that the following piping and support has less conservatism than assumed for the safety analysis and, therefore, requires remedial action. .
The overstress condition occurs at pipe support'H-43 on the reactor coolant fill header from the high head charging pumps. Loss of this line at this location would result in a loss of all three charging pumps during a seismic event. This overstress condition has been calculated for the summed loading factors of, deadweight, thermal and design basis earthquake loads.
