Nuclear Regulatory Commission Document Control Desk Hashington, DC 20555 1.icense DPR-35 Docket 50-293 BESPONSE TO ERC BULLETIN 85-03. SUPPLEMENT I This letter provides our response to NRC Bulletin 85-03, Supplement 1, which requested a re-examination and possible expansion of licensees' valve testing programs to verify the torque switch settings on safety related motor operated valves (H0Vs). Since the issuance of this Bulletin supplement, the NRC by
,          letter of August 8,1988 has accepted the revised Boiling Hater Reactor Owners Grcup (BHROG) report, NEDC 31322 Supplement 1, dated July 20, 1988.
He endorse the methodology of NEDC-31322 Supplement 1 for the selection of valves and their maximum expected diffe'ential pressure. Our endorsement results in no valves being added to the 21 H0V's reported to the NRC in our original Bulletin 85-03 response of December 31, 1986. It does result in a data change for two of the original 21 valves, which is reported in this letter's attaG1 ment.          The attachment also lists two new valves which we*e added to Pilgrim as a result of plant modifications made during this outage.
Boston Edison will complete Bulletin 85-03 activities in accordance with the schedule approved by the NRC letter dated April 14, 1988.

r Attachment to NRC Bulletin 85-03. Sucolement 1 Boston Edison provided data on 21 HOVs affected by Bulletin 85-03 in our letter of December 31, 1986. He have re-tvaluatad that data based on Supplement 1 and provided a data update on the following two pages. Changes are designated by a change bar in the right hand margin.
Changes to the original list are:
: 1) MO-2301-6 Maximum Openingz1 P rose from 25 psi to 40 psi.
: 2) H0-1301 -22 Maximum Opening /l P rose from 25 psi to 38 psi.
Two new valves were added to the list to reflect their addition to Pilgrim.
The new valves are shown on the attached schematic drawing of the HPCI Steam Lines Motor Operated Valves.
They are:
: 1) H0-2301-33 Vacuum Breaker Line Isolation Valve
: 2) H0-2301-34 Vacuum Breaker Line Isolation Valve
