5 Page 1 of 1 CHANGES TO CALLAWAY NUCLEAR PLANT INSERVICE TESTING PROGRAM Item 1:
Change: Delete Relief Request AL-2 Basis for Change:
It has been determined that a quarterly mechanical exercise of the valves while monitoring the required opening torque is a sufficient test to prove operability. This I
is clearly stated in ASME Section XI IWV-3522.
1 Item 2:
Change: Revise Relief Request AE-1 to allow the option of representative disassembly or seat leak testing valves AE-V-120,121,122,123 as an alternate testing method.
l Bauts for Change:
Seat leakage tests are being developed to test these valves.
Disassembly should remain as an option in the event that seat leak testing is deemed infeasible.
Item 3:
Change: Add EJ-5 to Relief Request column for valve EJ-HV-8840.
Basis for Change:
Relief Request designator was inadvertently omitted during the last program revision.
3 Item 4:
Change: Revise Relief Request Pol to increase the discharge pressure gage tolerance from ! 5 psig to i 10 psig.
Basis for Change: The gage manufacturer lists a higher i
minimum tolerance level than the 2 5 psig limit stated in Relief Request P01.
The new t 10 psig tolerance is consistent with the manufacturer specifications and still meets the 2% accuracy limit specified by i
ASME Section XI Table IWP-4110-1.
Item 5:
Change: Delete valves EM-HV-8870A,B and EM-HV-8883 from Inservice Testing Program.
Basis for Change: These valves were inadvertently added to the program in the last revision; these valves are not required to be tested.
Item 6:
Change: Add Relief Request EM-7 to program.
Basis for Change:
Relief Request EM-7 was inadvertently omitted at the. previous revision.
