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.

Section XI, ASME Boiler 5 Pressure Vessel

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

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.

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

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 tive 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.

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 impracti 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.

Test Requirement:
IWP-3210 Allowable Range of Inservice Test guantities Ba si s for Rel ief:
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,

(*-P212A)

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.
