Nuclear Regulatory Commission Attention: Document Control Desk Washington, D. C. 20555 Subjec.t: Catawba Nuclear Station, Units 1 and 2 Docket Nos. 50-413 and 50-414 IWV Program Revision Request
Dear Sir:
Please find enclosed Revision 13 to the Catawba Unit 1 and Revision 4 to the Catawba Unit 2 Ptanp and Valve Inservice Testing Program (IWV).
This change will revise a note on page II-B-3 concerning the commencement of testing during Cold Shutdowns which exceed 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.
Per the request contained in the introduction to the Staff's SER for Catawba's IWV Program (dated Jant:ary 8,1987), this revision is being provided for your review and approval prior to its implementation.
This request involves an application for approval of a revision to the IWV program, as such, pursuant to 10 CFR 170.21, a check for $150. is enclosed.
Any questions or comments may be directed to Mr. Roger Ouellette at (704)373-7530.
Very truly yours,

Z - Exercise valve (partial stroke) for operability every 3 months during power operation and exercise valve (full stroke) for operability during cold shutdown (mode 5).
CZ-Exercise check valve (partial stroke) toward the position required to fulfill its function during operation and exercise valve (full stroke) toward the position required to fulfill its function during cold shutdown (mode 5).
RR-Refer to Relief Request For Test Frequency.
BV-Pressure boundary valve leak rate test.**
- NOTE:
The following condition applies for all testing performed during cold shutdown:
For cold shutdowns less than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, valve testing does not have to be performed. However, for cold shutdowns expected to exceed 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, valve testing will commence as soon as possible, but no later than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> after reaching cold shutdown. Valve testing will proceed in a normal manner until.
all testing is complete or the plant is ready to return to I
power. A completion of all valve testing is not a prerequisite to return to power. Any testing not completed by the end of one cold shutdown will be performed during subsequent cold shutdowns, starting from the last test performed at the previous cold shutdown. For pressurizer PORV's only (INC32B, INC34A, INC36B), testing will be performed each cold shutdown prior to return to power, not to exceed once every 3 months.
l
- NOTE:
All leak rste tests are performed in accordance with 10 CFR 50, Appendix J, Type C lesk rate procedure with the exception of Pressure boundary valves, whose test is a differential pressure test with water as a medium. Test frequency will be in accordance with Tech Spec Surveillance Requirement 4.4.6.2.2.
