Dear M:
. Denton:
The referenced letter provided the Callaway Unit 1 pump and valve test program and explained the similarity to that for Wolf Creek.
In dis-cussions with the NRC's Mechanical Engineering Branch, it was learned that some changes to the program were required. The attachment to this letter provides revised pump relief request no. 2 and revised valve relief requests nos.1, 6, 7, 8, and 9.
Ir. addition, a new page (128A) has been added to include four check valves in the compressed air system. These changes are applicable to both Callaway Unit 1 and Wolf Creek.
Very truly vours, 44C Nicholas A. Petrick RLS/jdk Attachment cc:

PUMP RELIEF REQUEST NO. 2 SYSTEM:
Emergency Fuel Oil System COMPONENT:
PJE01A & PJE01B CLASS:
3 FUNCTION:
To provide fuel oil to the standby diesel generators.
TEST REQUIREMENT:
Measure bearing temperature and vibration and observe lubricant level.
BASIS FOR RELIEF:
There pumps are immersable centrifugal sump pumps located in the emergency fuel oil storage tanks.
ALTERNATE TESTING:
Vibration measurements will be made on the connecting piping quarterly.

VALVE RELIEF REQUEST NO. 1 SYSTEM:
M-02AL01 COMPONENT:
V006 V009 V012 V015 CATEGORY:
C CLASS:
3 FUNCTION:
Valves open with differential pressure to provide ?!1ow paths from Essential Service Water System to Auxiliary Feedwater Pumps during a DBA.
Normally closed.
TEST REQUIREMENT:
Exercise the valves every three months.
BASIS FOR RELIEF:
The testing of these valves would result in supplying chemically contaminated water to the steam generators and/or the con-densate storage tank.
i ALTERNATE TESTING: "
Valves v.ill be cuded manually during refueling.
VALVE RELIEF REQUEST NO. 6 SYSTEM:
Accumulator Safety Injection P&ID NO:
M-02EP01 COMPONENT:
8956A through 8956D i
CATEGORY:
C CLASS:
1 FUNCTION:
Opens with differential pressure to provide flow paths from the accumulators to the reactor coolant system cold legs and the reactor vessel.
Normally closed.
TEST REQUIREMENT:
Exercise valves once every three months.
BASIS FOR RELIEF:
During normal operation, the safety injection system has insufficient head to overcome reactor coolant system pressure.
Testing during shut-down increases the probability of a cold over-pressurization event to occur and is therefore in conflict with plant safety.
ALTERNATE TESTING:
A partial stroke exercise of the valves will be performed during cool down for refueling.
A
VALV_E RELIEF REQUEST NO. 7 SYSTEM:
Containment Spcay System P&ID NO:
M-02EN01 COMPONENT:
V002 V008
_ CATEGORY:
C CLASS:
2 TUNCTION:
Opens on differential pressure to supply containment spray water to the discharge nozzles in the recirculation moce.
TEST REQUIREMENT:
Exercise valves once every three months.
BASIS FOR RELIEF:
Valves can not be stroke exercised withouti violating the integrity of penetration numbers P-13 and P-16.
ALTERNATE i
TESTING:
These valves will be cycled manually in conjunction with the system air test per Technical Specification.

VALVE RELIEF REQUEST NO. 8 SYSTEM:
Containment Spray System P&ID NO:
M-02EN01 COMPONENT:
V003 V004 V009 V010 CATEGORY:
C CLASS:
2 FUNCTION:
Opens with differential pressure to provide flow paths for the containment spray system.
normally closed.
TEST REQUIREMENT:
Exercise valves once every three months.
BASIS FOR RELIEF:
Pumps can only be tested at partial flow (per FSAR section 6.2.2.1.4).
Therefore, valves in flowpath can only be tested at partial flow.
ALTERNATE TESTING:
Partial flow test the check valves when the spray pumps are tested by recirculation flow back to the RHST.

VALVE RELIEF REQUEST NO. 9 SYSTL.,
Containment Spray System P&ID NO:
M-02EN01 COMPONENT:
V013 V017 CATEGORY:
C CLASS:
2 FUNCTION:
Opens with differential pressure to provide flowpaths for the containment spray he'ader.
Normally clo.:ed.
TEST REQUIREMENT:
Exercise valves once every three months.
BASIS FOR RELIEF:
Normal flowpath cannot be used without dis-charging containment spray water from the nozzles.
f ALTERNATE TESTING:
These valves will be partial stroke tested by air flow l
during the system air test per Technical Specification.
