NTRODUCTION This report contains the official summary of the Startup Physics Tests performed on Turkey Point Unit 4 at the beginning of Cycle XI. The testing program was conducted in accordance with Operating Procedure 0204.3, initial Criticality After Refueling, and Operating Procedure 0204.5, Nuclear Design Check Test During' Startup Sequence After Refueling, and meets the minimum requirements of ANSI /ANS 19.6.1, Revision 0 (12-13-85), Startup Physics Tests for Pressurized Water Reactors.

Testing commenced on August 18,1986, at 0230 and was completed on August 29,1986, at 1705.

The Westinghouse Nuclear Design Unit 4 Cycle XI (WCAP-22027) is the design.

data from which deviations were measured for the purpose of verifying that acceptance criteria were met. The acceptance criteria stated are the more conservative of ANSI /ANS 19.6.1, Revision 0 or Operating Procedure 0204.5.

Additionally, Florida Power and Light Company design dato is presented for the purpose of benchmarking.

The contents of this report provide the documentation required by Technical Specification 6.9.l.a due to the addition of Hafnium Burnable Absorbers to the reoCior Core.

2.0 INITIAL CRITICALITY The approach to criticality began August 18,1986, at 0300 hours0.00347 days 0.0833 hours 4.960317e-4 weeks 1.1415e-4 months in accordance with Operating Procedure 0204.3, Initial Criticality After Refueling. Criticality was achieved August 18,1986, at 0959 hours0.0111 days 0.266 hours 0.00159 weeks 3.648995e-4 months by withdrawing control rods to 160 steps on Bank D and diluting 8,800 gail'ons of water.

Upon attaining criticality, the flux level was increased to 1 x 10-8 amps on the intermediate range to obtain critical data.

SUMMARY

OF TESTS This section provides a summary of the results of the low power physics tests in tabular form along with the Westinghouse and FPL design data. For each test, the acceptance criteria is listed at the bottom of the table. All of the tests in this section meet their acceptance criteria, except for the ARO and Reference Bank in boron endpoints. After careful reanalysis of the RCS samples, these endpoints were determined to be measured 50 to 60 ppm below the design. Although the measured values were beyond the acceptance criteria, Westinghouse determined that they presented no adverse safety implications and gave their concurrence to continue with power ascension (see Appendix 1) in accordance with ANS/ ANSI 19.6.1. Rl:2

3.1 NUCLEAR HEATING j

The point of adding Nuclear Heat was determined in accordance with Operating Procedure 0204.3, Initial Criticality After Refueling, Step 3.15 and Appendix A.

This is performed by establishing a small positive startup rate and measuring the point (flux level) at which Tav~ departs from its established, steadv value.

g Nuclear heating was measured to first occurred at:

Picoammeter N-35 N-36 4.30 x 10-7 5.05 x 10-7 5.33 x 10-7 All physics tests were conducted at or below 1.0 x 10-7 amps on the picoammeter connected to N-44 to assure Nuclear Heating did not occur.,

R1:2

3.2 REACTIVITY Vi PERIOD Reactivity Computer checkout was done in accordance with Operating Procedure 0204.3, initial Criticality Af ter Refueling, Step 8.16 and Appendix B. This checkout is performed by inserting small (<60 pcm) positive and negative reactivities using rod motion, measuring the period generated and the indicated worth, and then comparing design worths to measured worths for the given period.

3.3 BORON ENDPOINTS (PPA 4)

The Boron Endpoints noted below are determined as per Operating Procedure 0204.5, Appendix A.

A just-critical condition is established as near as practicable to the required rod configuration (i.e., ARO). The RCS boron concentration is determined and then adjusted by the ppnv worth of the reactivity (measured in pcm) by which the actual critical state deviated from the design condition.

3.4 ROD TORTH Rod worths were performed in two different manners as per Operating Procedure 0204.5, Appendices D and E.

The Reference Bank (highest predicted worth) was diluted into the core.

The boron concentration prior to and subsequent to this evolution was determined and the difference in the two borons is defined as the

. boron (Rod) worth of the Bank (Table 3.4).

Additionally, the differential and integral worth of the bank was measured and plotted.

- 3.6 TEMPERATURE COEFFICIENT The method used to determine the temperature coefficient in Operating Procedure 0204.5, Nuclear Design Check Tests During Startup Af ter Refueling, was modified to meet the requirements of the new ANSI /ANS standard.

The standard recommends that the average of the measured values from one heat-up and the corresponding cool-down be used as the actual measured value. Previously, the

~

value from each heat-up and each cool-down had been treated as separate measurements.

The values determined for this testing sequence (in pcm/0F) are:

4.0 SHUTDOWN MARGIN The Shutdown Margin was calculated prior to power escalation to verify adequate shutdown capability. For this calculation, design rod worths were reduced by 10%,

and the results show shutdown margin at BOC and EOC. The following is a summary of the results:

e-6.0 FULL POWER CRITICAL BORON MEASUREMENT The final part of the physics testing sequence is a comparison of the measured to predicted Hot Full Power, equilibrium condition boron concentration. This test is defined in the ANSI /ANS standard.

The results of this test are as follows:

TABLE 6.0.1 Predicted Measured Burn-up CB CB Difference 850 1332 ppm 1356 ppm

-24 ppm Acceptance Criteria is +50 ppm RI:2

APPENDIX 1 Westinghouse Proprietary class 2 1

August 20, 1986 Frank D Popa, x2151, 412 374-2151 Westinghouse NFO MMOB 3-05 Monroeville, Pa. 15146 MEMO TO:

Mr. R. Mende

SUBJECT:

HZP Boron Concentration We have examined the safety calculations for Turkey Point Unit 4. Cycle 11 assuming that the boron concentrations may be less than that used in the safety analysis. There are no adverse safety implications.

In some cases lower boron concentrations make the postulated accidents less severe.

In most cases there is essentially no effect. Therefore we would recommend that FPL resume the normal startup sequence and proceed to power.

In particular, there is no need to take a HZP flux map. The excellent agreement in RCC worth between measurements and predictions precludes the possibility that there are large power distribution errors. Additionally there is sufficient margin at 30% power that no safety hazard exists for even unlikely possibilities such as an enrichment error, misloaded RCC, or misloaded assembly.

We will begin examining possible causes of a misprediction of the HZP boron concentration. There is at least one explanation which we have already begun to examine which would reduce the HZP boron predictions by 30 ppm. We added 30 ppm to our HZP predictions to account for the difference between our 30 PALADON model and our 20 TURTLE model.

Perhaps we should have trusted the 3D PALADON results without adding the bias. The Turkey Point cores have many 3D features ( part length bps and part length PTS bps ) which call into question the accurry of 2D TURTLE calculations. We have, however, attempted to account for these effects in TURTLE. The question is whether or not we did it in the best way possible. The closer agreement of 3D PALA00N with measurement calls into question the details of this process.

An effect which was not modeled in our startup predictions was the decay of some of the radioactive isotopes in the burned fuel during the 6 month shutdown.

It is the isotopes with half lives in the intermediate l

range with which we are concerned. The long lived isotopes will not decay enough to matter in a 6 month shutdown. The short lived isotopes are accounted for in our standard methods. This effect is likely to be 5 to 15 ppm, also reducing the predicted BOL tlZP boron concentration. This will also be examined.

We are also pursuing any differences which we uncover between the Westinghouse models and the FPL nuclear models produced by the General Office. The FPL models gave significantly lower predictions for the HZP BOL boron concentration than did the Westinghouse models.

In conclusion, we will examine several areas to determine if there is a need to correct the predicted startup baron concentration.

c.UG.20 'S616:20 WESTINGHOUSE T1ALL CFC WIRE RCCM F.0?

Mr. R. Mende August 20, 1986 These effects may total 40 ppm or more in the direction to make the predictions and measurements closer to one another.

There are no adverse safety implications of the lower boron concentration measured. We would recomend that the normal startup procedure be followed and that the plant proceed to power as originally planned.
