Dear Mr. Eisenhut:

Re: Turkey Point Units 3 and 4 Docket Nos. 50-250 and 50-251 Revisions to Inservi ce Test Pro ram for Pum s and Valves Florida Power 8 Light submitted a revision to the Inservice Test ( IST) Program for Pumps and Valves for Turkey Point Units 3 and 4 in letter L-84-84 dated March 30, 1984. The effective date provided in that submittal was corrected in letter L-84-190 dated July 26, 1984.

The purpose of this submittal is to add additional components to the Pump and Valve Test Program. These components include the charging pumps, spent fuel pit cooling pumps, boric acid transfer pumps, and associated valves.

Associated with these additions are revisions to Table I, Table IV, and associated relief request basis.

We have set the effective date of implementation for the charging pumps and boric acid transfer pumps as six months from the date of this letter. The implementation date for the spent fuel pit cooling pump has been set at January 1, 1986, to allow for completion of modifications that are required to do the testing.

Should you or your staff have any questions on this information, please contact us.

Very truly yours, J. W. Williams, Jr.

High Head Safety Injection Pump No. B (P215B)

High Head Safety Injection Pump No. C (P215C)

High Head Safety Injection Pump No. D (P215D)

Test Requirement: IWP-4600 Flow Measurement Basis for Relief: Section XI, ASME Boiler 5 Pressure Vessel Code, requires measurement of flow rate using a rate or quantity meter installed in the pump test circuit.

These pumps use a fixed hydrau',ic resistance system with an orifice installed in the pump recirculation line (IWP-1400) .

Alternate Testing: Measure di fferenti al pressure (IWP-4240) across 'the pump during the quarterly pump test. The measured differenti al pressure across the pump shall then be compared to the established reference value. This provides for an indirect measure of flow rate and verifies the operational readiness of the pump (IWP-1500)

2) PUMPS:

Intake Cooling Water Pump No. *A *-P9A)

Intake Cooling Water Pump No. *B ~-P9B)

Intake Cooling Water Pump No. *C (~-P9C)

Test Requirement: IWP-4310 (Bearing Temperature Measurement)

Basis for Relief: The pump bearings for these vertical centrifugal pumps are located inside the pump housing which is submerged. The bearings are water lubricated with no provi sions for temper ature measurement.

Alternate Testing: Measurement of vibration amplitude and the other required paraneters during each pump test will provide for the detection of changes in the mechanical characteristics of the pump.

3) PUMPS:

Residual Heat Removal Pump No. *A (*-P210A)

Residual Heat Removal Pump No. *B (*-P210B)

Test Requi rement: IWP-4310 (Bearing Temperature Measurement)

'asis for-Relief: The pump bearings for these vertical centrifugal pumps are located inside the pump housing which is submerged. The bearings are water lubricated with no provi sions for temperature measurement.

Alternate Testing: Measurement of vibration amplitude and the other required paraneters during each pump test will provide for the detection of changes in the mechanical characteristics of the pump.

4) PUMPS:

Diesel Oil Transfer No. 3 ( 3-P 10)

Diesel Oil Transfer No. 4 (4-PIO)

Test Requi rement: IWP-4600 Flow Measurement Basi s for Reli ef: Section XI, ASME Boiler 8 Pressure Vessel Code; requires measurement of flow rate using a rate or quantity meter installed in the pump test circuit.

Alternate Testing: Flow r ate will be calculated, based on the change in Diesel Oil Day Tank level and measured time.

Test Requirement: IWP-4300 Temperature Measurement and IWP-3500 Duration of Tests Basi s for Relief: The Diesel Oil Transfer Pumps have no installed recirculation flow path. The Diesel Oil Day tank level control system provides for a di rect fl ow path from the Diesel Oil Storage Tank to the Day Tank. With automatic pump start on low level in the Diesel Oil Day Tank and automatic pump, stop when the high level setpoint is reached, the typical operating time for these pumps is less than 10 minutes. Therefore, operation of the Diesel Oil Transfer pumps for the 30 minute minimum run time required by IWP-3500 is impr acti c al .

Alternate Testing: The Diesel Oil Transfer Pump bearing temperature will be measured during normal pump tests.

5) PUMPS:

Charging Pump No. *A (*-P 201A)

Charging Pump No. *B ("-P201B)

Charging Pump No. *C (*-P 201C)

Boric Acid Transfer Pump No. *A (*-PZ03A)

Boric Acid'ransfer Pump No. *B (*-P203B)

Di ese1 Oi l Trans fer Pump No. 3 (3-P10)

Diesel Oil Transfer Pump No. 4 (4-P10)

Test Requirement: IWP-4240 Di fferenti al Pressure Basis for Relief: Pump suction pressure taps were not provided in the original design of these systems. Therefore, measurement of, pump suction pressure or measurement of differential pressure is impractical.

Alternate Testing: Boric Acid Transfer and Diesel Oil Transfer Pump suction pressure will be calculated, based on Tank level and the fluid elevation above the centerline of the pump.

The charging pumps ar e posi ti ve di spl acement pumps.

Therefore, pump discharge pressure and flow are more representative of pump performance than di fferenti al pressure and flow. However, charging pump suction pressure will be calcul ated, based on Volume Control Tank (VCT) level, VCT pressure, and the fluid elevation above the centerline of the charging pump.

6) PUMPS:

Boric Acid Transfer Pump No. *A (*-P203A)

Boric Acid Transfer Pump No. *8 (*-P2038)

Test Requi rement: IWP-4310 Bearing Temper ature Measurement Basis for Relief: The Boric Acid Transfer Pumps are completely enclosed with thermal insulation and heat traced to prevent precipitation of boric acid from the solution.

Therefore, bearing temperature measur ement i s impr acti c al .

Alternate Testing: Measurement of vibration anplitude and the other required paraneters during each pump test wi.ll provide for the detection of changes in the mechanical characteristics of the pumps.

7) PUMPS:

Charging Charging Pump No. *A (*-P201A)

.Pump No. *B (*-P201B)

Charging Pump No. *C (*-P201C)

Test Requirement: IWP-3210 Allowable Range of Inservice Test guantities Ba si s for Rel i e f: The nuclear safety related function of the charging pump is to provide for boration of the Reactor Coolant ,

System (RCS) to the'required shutdown margin from hot shutdown to the cold, Xenon-free shutdown condition.

This safety function can be fulfilled with a charging pump flow of 45 gpm plus flowrates to compensate for both RCP seal leak-off and RCS leakage at a nominal RCS pressure of 2235 psig.

Alternate Testing: Minimum acceptance criteria for charging pump operability shall be 45 gpm plus flowrates to compensate for both RCP seal leak-off and RCS leakage at a nominal RCS pressure of 2235 psig. If this criteria can not be met, the charging pump shall be declared inoperable and not returned to service until the corrective action requirements of Subarticle IWP-3230 (Corrective Action) are met,

8) PUMPS:

Spent Fuel Pit Cooling (*-P 212A)

Spent Fuel Pit Cooling (*-P212B)

Test Requirement: IWP-4500 Flow Measurement Basis for Relief: The original spent fuel cooling system design does not provide for flow measurement. There are no flow nozzles, flow orifices, or pressure taps for flow measurement. Therefore flow measurement i s impr actical.

The original spent fuel cooling system design was based on removal and replacement of the spent fuel pit pump when the system function could not be fulfilled. The time period associated with the removal and replacement was within the time the spent fuel cooling system could be out of service.

Alternate Testing: Continue operation of the spent fuel pit cooling system based on original system design. Design, fabricate and install a flow measurement device using either a bypass loop or the normal system flow path.

Estimated time of completion would be December 31, 1985.

Function: Prevents reverse flow from the boron addition system header to a non-operating boric acid transfer pump.

Test Requirement: IWP-3620 Basis for Relief: Testing either of these valves during plant operation would cause an addition of excess boron to the Reactor Coolant System resulting in a reactor shutdown.

Alternate Testing: These valves will be tested at cold shutdowns.
