The changes (4 pages) attached to this letter comprise a revision to our December 7, 1979 submittal incorporating additions and clarifications to the program and a relief request.
Your review of the attachments and the program as revised and approval of the relief requests identified by the revised program are requested.

IWP TESTING Pumps provided with emergency power sources are required to be tested. This includes pumps powered by the emergency diesel generator, the two core spray pumps and the electric fire pump, and the self-powered diesel fire pump.
Tests to be performed on the'se pumps are as follows:
1.
Core Spray Pumps - The pumps will be tested once each reactor shutdown for refueling. See request for reli;f.
2.
Electric Fire Pump - The electric fire pump will be tested each reactor shutdown (but not more frequently than monthly).
3.
Diesel Fire Pump - This pump will be tested each reactor shutdown (but not more frequently than monthly).
The parameters to be measured during these tests are tabulated below.
Rotative Inlet Flow Bearing Pump Name Speed Pressure AP Rate Vibration Temperature Core Spray R
R R
NA*
R bbi Electric Fire ES ES ES NA*
ES NM Diesel Fire ES ES ES NA*
ES NM ES - Every shutdown (but not more frequently than monthly).
Y - Yearly.
R - Once/ Refueling.
NM - No measurement possible - just monitor vibration.
This is b'ecause the core spray, electric and diesel fire pump bearings are cooled nnd lubricated by the water being pumped.
Due to water temperature variations and bearing inaccessibility, there is no method that will establish a meaningful bearing reference temperature. Thus, no measurement will be taken.
- Per IWP3100, differential pressure will be used to establish pump acceptability.
NOTE: The acceptable ranges of parameters will be as required in Table IWP-3100-2.

RELIEF REQUEST BASIS System:
Core Spray System l
Valve:
M07072 Category:
B Class:
2 i
Function:
To provide a third path of fire water to the containment.
Test Requirement:
Exercise quarterly.
Basis for Relief:
Exercising this valve will introduce fire water into the j
inhibited water of the core spray pump piping. Exercising during each shutdown will minimize the amount of fire water that enters the core spray pump piping.
Alternate Testing: Each reactor shutdown but not more frequently than monthly.
