D ck2t No. 50-346 License No. NPF-3 Serial No. 1-637 Attachment Action Item a.
For motor-operated valves in the high pressure coolant injection / core spray and emergency feedwater systems (RCIC for BWRs) that are required to be tested for operational readiness in accordance with 10 CFR 50.55a(g), develop and implement a program to ensure that valve operator switches are selected, set and maintained properly. This should include the following components:
a.
Review and document the design basis for the operation of each valve. This documentation should include the maximum differential pressure expected during both opening and closing the valve for both normal and abnormal events to the extent that these valve operations and events are included in the existing, approved design basis, (i.e., the design basis documented in pertinent licensee submittals such as FSAR analyses and fully-approved operating and emergency procedures, etc). When determining the maximum differential pressure, those single equipment failures and inadvertent equipment operations (such as inadvertent valve closures or openings) that are within the plant design basis should be assumed.
Response to Action Item a.
The attached " Table of Results - IEB-85-03(a)" provides the results of Toledo Edison's review of the design basis for the operation of each valve in the requested systems. This design review was performed in accordance with Nuclear Engineering Procedure NEP-092, Establish D/P Limits and Tests for Motor Operated Valves (attached to item d.).
The maximum differential pressure during both opening and closing of each valve was determined consistent with the design basis events documented in the USAR analyses and the Davis-Besse Nuclear Power Station normal and emergency operating procedures, i.

Attachment-Action Item b.
Using the results from item a.,
establish the correct switch settings.
This shall include a-program to review and revise, as necessary, the methods for selecting and setting all switches (i.e., torque, torque
-bypass. position limit, overload) for each valve operation (opening and closing).
If the licensee determines that a valve is inoperable, the licensee shall
.also make an appropriate justification for continued operation in accordance with the applicable technical specification.
Response to Action Item b.
Action item b. requires that the results of item a. be used to establish the correct switch settings including a program to review and revise, as necessary, the methods for selecting and setting all switches for each valve operation-(opening and closing).
Toledo Edison's program to establish, review and revise the settings for valve operator switches (torque, torque bypass, position limit) includes
~
the results of item a.,'and is covered by Nuclear Engineering Procedure NEP-091, Motor-Operated Valve Data Evaluation (attached to item d.).
This program will be completed prior to Restart.
I
q Dockst No. 50-346 License No. NPF-3 Serial No. 1-637 Attachment Action Item c.
Individual valve settings shall be changed, as appropriate, to those established in item b.
Whether the valve setting is changed or
-not, the valve will be demonstrated to be operable by testing the valve at the maximum differential pressure determined in item a with the exception that testing motor-operated valves under conditions simulating a break in the line containing the valve is not required. Otherwise, justification should be provided for any cases where testing with the maximum differential pressure cannot practicably be performed. This justification should include the alternative to maximum differential pressure testing which will be used to verify the correct settings.
Each valve shall be stroke tested, to'the extent practical, to verify that the settings defined in item b have been properly implemented even if testing with differential pressure cannot be performed.
Response to Item c.
Action item c. requires that individual valve settings shall be changed, as appropriate, to those established in item b.; and, further that the valves either be tested at the maximum differential pressure determined in action item a. or justification be provided why testing cannot practicably be performed. Additionally, each valve shall be stroke tested to the extent practical.
Toledo Edison's program to implement change to valve switch settings is contained in Davis-Besse Maintenance Procedure MP-1410.32 Testing of Motor-Operated Valves Using MOVATS (attached to item d.).
This procedure requires each valve to be stroke tested to verify proper valve and operator operation. Our program to demonstrate valve operability is based on M0 VATS testing of all nuclear safety related valves followed by confirmatory testing of a representative sample of valves at their maximum differential pressure. Not all valves will be differential pressure tested.
Nuclear Engineering Procedure NEP-092 provides the program used to select the representative sample of valves to be tested to confirm the adequacy of corrective maintenance procedures. This procedure evaluates the practicability of specific valve differential pressure testing. This methodology has been reviewed with the NRC Staff and submitted in our letter to Mr. Denton, Docket No.80-346, Serial No. 1258 dated April 10, 1986. This program will be completed prior to plant Restart.
1 D:ck2t No. 50-346 License No. NPF-3 Serial No. 1-637 Attachment Action Item d.
Prepare or revise procedures to ensure that correct switch settings are determined and maintained throughout the life of the plant. Ensure that applicable industry recommendations are considered in the preparation of these procedures.
Response to Item d.
Toledo Edison's procedures to ensure correct switch settings are determined and maintained are already in place and consist of the following:

As you will note in the attached MOV evaluation reports, we have coded or classified each co m at as follows:
Code 1 - Strongly recommend that the condition noted be corrected immediately in order to assure continued reliable functioning of the valve.
Code 2 - At the next shutdown, the condition noted should be investigated and perhaps corrected at that tima if possible.

3.
Test conditions for the representative sample of test valves (Exhibit VI).
2.0 SCOPE This procedure applies to all Limitorque Motor Operated Valves types SMB and SMC, and shall be performed on MOVs listed in Exhibit I.
3.0 RESPONSIBILITY The Nuclear Engineering Group Director is responsible for the preparation, and use of this procedure by engineers who have received the following training:
1.
Principles of operation of Limitorque Operators.
2.
