CALLA 1VAY PLANT DOCKET NUMBER 50-483 CALLAWAY PLANT INSERVICE TESTING PROGRAM UPDATE This letter supercedes "ULRNC-3602" dated June 16, 1997, which transmitted Revision 18 of the Callaway Plant Inservice Testing Program. This letter corrects distribution and minor typographical errors. Please dispose of the previous letter.
IST Program updates have been made via Revisions 15a,16, and 17 which are included in Revision 18. In accordance with 10CFR50.55a(f) and the guidance provided in NUREG 1482 ' Guidelines for Inservice Testing At Nuclear Power Plants," this revision is being provided to reflect major changes to the IST Program. Attachment 1 is a brief description of the changes, and Attachment 2 provides a complete copy of Revision 18 of the IST Program.
Ifyou have any questions concerning this submittal, please contact us. /

l "O/C" to *C" available for the TD AFP. In the event of a SGTR . l these valves must be closed to stop offsite release paths. As these are manual isolation valves without remote position indication there are no testing requirements in the open (passive) position. Thus.
the safety function column for these valves has been j changed to "C"(active position). Verification that these valves can be closed will continue to be done during refueling outages as stated in Refueling Justification AB-03.
BGV0135 Changed the SFTY POS column This component has been determined to have an from "C" to "O/C" Added active safety function in the partial open position in "PS/RF" to the TEST PERF/FREQ order for it to relieve pressure between column.

In the normally closed position DEF JUST column. this valve serves a passive function for containment isolation. Per Tabic I of OM 10 this valve requires valve seat leak rate testing (Category A passive valve test per paragraph 4.2.2) and exercise testing (Category C active check valve per OM 10 paragraph 4.3.2). Refueling Justification BG-02 l was revised to test the open function of this valve on a extended test frequency. Since this valve does not have remote position indication it does not require i position indication testing per OM-10 paragraph l 4.1.
