Toledo Edison, by letter dated March 13, 1992 (Reference Serial Number 2026), submitted an application for an amendment to the Davis-Besse Nuclear Pover-Station (DBNPS), Unit 1 Operating License Number NPF-3 Appendix A, Technical Specifications (fS), proposing changes involving TS 3.4.11, Reactor Coolant System - Reactor Coolant System Vents, and-TS 6.9.2,-Reporting Requirements - Special Reports.
The Reactor Coolant System (RCS) Loop 2 vent path became inoperable on March 1, 1992, when it was manually isolated by valve RC 44-to minimize rotential RCS leakage. To avoid an unwarranted plant shutdown in the j.
event that the inoperable RCS Loop 2 vent path could not-be returned to l-

Toledo Edison has kept the Nuclear Regulatory Commission (NRC) staff-informed (by telephone) of its ef forts to restore the affected RCS Loop 2 vent path to operable status.
On March 25, 1992, the RCS Loop 2 vent path solenoid valves RC 4610A and RC 4610B vere stroked (from the control room) to ensure a proper seating.
On March 26, 1992, a o
L containment entry was made to open upstream manual valve RC 44.
