Dear Mr. Grier:

In accordance with Appendix A, Beaver Valley Technical Specifications, Licensee Event Report LER 81-047/01P, Technical Specification 6.9.1.8.1,

~

Administrative Controls, is submitted. This oc'c'urrence was reported on the NRC Hotline phone and to Mr. D. A Beckman, the Beaver Valley NRC Resident Inspector, at 0140 hours0.00162 days <br />0.0389 hours <br />2.314815e-4 weeks <br />5.327e-5 months <br /> on June 6, 1981.

At approximately 0100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> on June 6, 1981, during his normal plant tour, the pri=ary auxiliary building operator found the emergency cooling water supply valve to the high head safety injection pumps unlocked and closed. The operator i=m:diately informed the Control Room and then opened the valve. At 0115 hours0.00133 days <br />0.0319 hours <br />1.901455e-4 weeks <br />4.37575e-5 months <br />, the Nuclear Shift Foreman verified the valve cpen and installed a new chain and lock. The valve in question had been verified to be correctly positioned on the 1600-2'00 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> shift. The Nuclear Shift Supervisor immediately secured all access to vitsi areas. A verification of all locked and sealed Engineered Safety Feature (ESF) equipment was begun and satisfactorily ecmpleted at 0300 hours0.00347 days <br />0.0833 hours <br />4.960317e-4 weeks <br />1.1415e-4 months <br />.

The safety implications due to the closure of this valve would have resulted in a loss of high head safety injeccion capability through that flow path. The alternate hi;ch pressure injection flou path would have required manual operator action to allev the system to c?mplete its intended function. Low pressure safety injection was available at all times.

Very truly yours,

h ${ W J. A. Werling (
