Dear Mr. Haynes:

In accordance with Appendix A, Beaver Valley Technical Specification 6.9.1.8, Administrative Controls, Licensee Event Reports LER 82-007/0lP and LER 82-008/0lP are submitted. These occurrences were reported to Mr. R. R.

Kiemig, the NRC Region I Duty Officer, at 1700 hours0.0197 days <br />0.472 hours <br />0.00281 weeks <br />6.4685e-4 months <br /> on March 12, 1982, and to Mr. D. A. Beckman, the BVPS NRC Resident Inspector, at 1100 hours0.0127 days <br />0.306 hours <br />0.00182 weeks <br />4.1855e-4 months <br /> on March 15, 1982.

During records update of the analysis required by IE Bulletin 79-14, an overstress condition was found to exist on the "A" Steam Generator main steamline upstream of its isolation valve at monoball support H-2. The failure of this support, which has a safety factor of 3 versus a required safety factor of 4, could result in the loss of secondary coolant to the "A" Steam Generator. This condition has been analyzed in the Final Safety Analysis Report and addressed through emergency procedures.

Required modifications to bring the support to within acceptable limits will be made through Design Change Package (DCP) 305. The work will be completed prior to plant startup.

An o erstress condition has also been determined to exist on the Component Cooling Water line upstream of the "lC" Reactor Plant Component cooling water pump suction isolation valve at supports H-15 and H-16. The f ailure of these supports, which have a safety factor of 2.5 versus a required safety factor of 5.0, could result in the loss of the Component Cooling Water System.
