- Mr. Jhmnu G.
Keppler 2-Februa$y_5,.1976 authorizcc purchases from previously unevaluated vendorn but pro-vides the guidance nocded to encure the quality of the material roccived.
The' attention given thin infraction coupled with the procedure revicw by the parties concerned should prevent recurrence.
.The following supplementn_the " Corrective Action to Avoid Recurrencc" for Infract. ion No. 5.
The apparent' incorrect _ operation of the LPCI loop select logic system was noted on September 29, 1975 following a reactor scram.
The respon'aible operating.cngineer was cognizant 'of the situation and= initiated activitics to dctormine the specific condi-tions and corrcctive action.
The action required by DAP 2-12 was to initiato a deviation repor:t and the required review to deterninc appropriate operating limits and corrective measurcs.
The deviation report was initiated on October 9, 1975, after the reactor had bocn returried to cervice.
In retroupact, it is our judgment that had the;cauce of the inccrrect functioning.of the loop select logic system been identified prior to returning the reactor to servico, the corrective' action would have.bcon required
' prior to return to cervicc. -Due to tho'dclay in preparing the do-viation report, the cause of the incorrect functioning van not known at the time of startup.
This matter hac been-thoroughly re-viewed by the responsible operating engineer and the importance of following procedures in these and similar circumstances ic* clear.
If you require any further information concerning this.
matter, please contact my offico.
Very truly yours, f 2.f R. L. Dolger Assistant Vice President 9'
