1.1 Attached is a copy of Operations Department Procedure ODP-ZZ-00015, " Reactor Trip Review," as i
requested by the Staff.
This program will be fully implemented by October 1, 1984.
I 1.2 This item is complete per the Staff.
2.1 Procedures to effect the development of the Callaway Q-List and ensure our interface with Westinghouse have been issued.
These programs will be fully implemented by December 31, 1984.
2.2 Our interface with other vendors will follow the recommendations of the associated NUTAC report,
" Vendor Equipment Technical Information Program,"
issued in March 1984.
This program will be fully implemented by September 1985.
1 3.1/3.2 As discussed with the Staff, administrative procedures to ensure post-maintenance testing and incorporation of test guidance were in place prior to the development of the affected maintenance procedures.
It is our position that, due to the vintage of Callaway, an additional review to provide this reassurance would be redundant to our normal procedure development process and is not justified.
Technical Specification changes will be handled via the normal ~ license amendment process.
The implementation date for this item is the same as the date of this submittal.
i 4.1 Modified Undervoltage Trip Attachments for the bypass breakers will be installed by October 1, 1984.
4.2.1 Preventive Maintenance Procedure MPE-SB-OS001 covers the inspection, cleaning, and lubrication of reactor trip switchgear during each refueling outage.
This procedure covers the following salient points:
I.
Switchgear 1.
Inspect for discoloration, overheating, or weakened insulation.
2.
Verify wiring connections, mounting brackets, and linkage.
3.
Perform megger tests of buses.
4.
Clean switchgear with vacuum and lint-free rags.
5.
Clean buses and contacts with Stoddard's solvent (or Westinghouse 455812CA).
i. !
II.
Breakers i
I l.
Inspect for contact clearances.
i 2.
Clean breakers with lint-free rags.
3.
Clean contacts with Stoddard's solvent (or Westinghouse 155812CA).
4.
Lubricate breakers per Instruction Manual with Dow Corning Molykote C-40.
The interval-between lubrications will not exceed 500 breaker operations as per the i
Instruction Manual.
5.
Perform megger tests of breakers.
6.
Perform mechanical test by manually tripping breakers.
7.
Subsequent to the above, an electrical test of the breaker is performed to verify proper operation.
j The Westinghouse Owner's Group compilation of maintenance information for the reactor trip i
switchgear is expected by July 1984.
This information will be incorporated, as appropriate, in i
j a fully implemented program by December 31, 1984.
4.2.2 The details of our trending program for reactor trip switchgear will be provided concurrent with its implementation date of December-31, 1984.
4.2.3/4.2.4 The results of the life cycle testing program and replacement interval information are expected by December 1984.
These results will be incorporated into our preventive maintenance program prior to i
startup following the first refueling outage.
4.3 This item is complete per the Staf f.
