Question No. 1.

! Confirm that the most limiting opening and closing requirement (pressure l . differential and/or flow rate) for all nuclear safety related motor

! operated valves will be identified before restart and will meet present design requirements.

Response to Question No. 1.

i l

Toledo Edison has identified the most limiting opening and closing require-i ments (pressure differential and/or flow rate)-for all torque seated.

nuclear safety related (NSR) motor operated valves (MOVs), attached. This includes all valves considered for confirmatory testing against their most

( limiting operational requirement.

The remaining most limiting opening and closing requirements for position seated MOVs (i.e. butterfly, dampers, etc.) is still in the preparation and review process.

This process is being performed in accordance with Nuclear Engineering Procedure NEP-092, attached. The summary list of limiting requirements developed using methodology in NEP-092, for all NSR-MOVs, will be completed prior to restart.
