PUMP IST PROGRAM II.1 INTRODUCTION This section presents the program for inservice testing (IST) of safety-related pumps at Unit 2 of the Farley Nuclear Plant, in compliance with the l
requirements of 10 CFR 50.55a.
This program has been prepared to the I
requirements of the American Society of Mechanical Engineers (ASME) Boller and Pressure Vessel Code,Section XI, Subsection IVP, 1983 Edition with Addenda through Summer 1983, for ASME Class 1, 2, and 3 pumps which are provided with an emergency power source and perform a specific function in shutting down the reactor or mitigating the consequences of an accident.
II.2 PUMP IST PROGRAM CONCEPT to this section addressesSection XI testing requirements for all ASME Class 1, 2, and 3 pumps provided with an emergency power source, and which are required to perform a specific function in shutting dovn the reactor or mitigating the consequences of an accident. Test requirements determined to be impractical for a large number of pumps have been addressed in Section I under General Relief Requests for Pumps.
In addition to those general relief requests, this section includes requests for relief from Code requirements found to be impractical for specific pumps.
Each relief request provides justification for deviation from the Section XI specified test and proposes appropriate alternate testing.
II.3 CODE CASES Code Case N-472 listed in Regulatory Guide 1.147 Revision 8 vill be used by i
Alabama Power Company for pump vibration testing.

Service Water Pump:
P001A-A, P001B-A, P001C-AB, POO1D-B, P001E-B Class:
3 Function:
Provide cooling water to safety-related equipment.
Test Requirement:
Table IWP-4110-1 requires that flow rate instrument accuracy be +2 percent of full-scale.
Basis for Relief:
In order to obtain the 1.1 percent i
accuracy for the installed annubar flow I
elements, they must be installed with at lease 3 to 4 pipe diameters downstream and 6 pipe diameters upstream.
Due to system pipe configuration, the downstream installation is in compliance but the upstream installation is a half-pipe diameter short.
The annubars are certified for a 0.1 percent repeatability.
Repeatability is a more i
important consideration in monitoring l
for pump flow degradation.
All flow measuring instrumentation associated with the annubars is in compliance with the requirements of Table IWP-4110-1.
Alternate Testing:
The installed annubar flow elements will be used to measure pump test flow rate to the requirements of Table IWP-3110-2.

These_ reactor vessel head-vent valves are Target Rock solenoid operated _ valves._.The. valve position indicators are-located in the solenoid coil circuit-and do not provide a positive means for valve position verification or-valve stroke
- timing.
In order to verify that the valves
- exercise open and reclose, it is-necessary to
~
establish flow through the vent lines.-
Flow cannot be established through the vent lines except at refueling or' cold shutdown when proper plant-conditions for testing can:be established.
To insure that_a stuck open valve would not.cause an_ uncontrollable. rapid depressurization it is necessary that RCS pressure be less-than_50 psig.-
-Alternate testing:
These valves-will be-full-stroke _ exercised-and<
the head vent flow path verified operable at refueling or at least:every 18 months as required
- by Plant Technical Specifications.
In addition, these-valves-willibe_ exercised at~ cold shutdown if.RCS pressure is less than 50 psig.

FNP-2-H-067 RELIEF REQUEST 02P19-RV-2 System:
Instrument Air Val,ve:
QV004 Category:
AC Class:
2 Function:
Backup nitrogen supply to pressuriter PORVs.
ASME Section XI Quarterly Test Requirements:
Verify forward flow operability quarterly or at cold shutdown (IVV-3521).
Basis for Relief:
There are no system design provisions for verification of forward flow operability and testing vill require isolation and venting of the instrument air header.
Instrument air supplies a number of components inside containment whict' are necessary for normal operation.
Testing during normal operation would deprive these components of their normal air supply, and since the system has no reserve air storage capacity, could result in operating transients and a possible forced plant shutdown.
Alternate Testing:
This valve vill be forward-flov verified at refueling when instrument air can be isolated without causing loss of instruments and components necessary for plant operations.
