PREFACE Serial No.17-017 Docket No. 50-280 Enclosure This report presents the analysis and evaluation of the physics tests that were performed to verify that the Surry Unit 1 Cycle 28 core could be operated safely, and makes an initial evaluation of the performance of the core. This report was performed in accordance with DNES-AA-N AF-NCD-5007, Rev. 3 [Ref. 17]. It is not the intent of this report to discuss the particular methods of testing or to present the detailed data taken. Standard testing techniques and methods of data analysis were used. The test data, results and evaluations; together with the detailed startup procedures, are on file at Surry Power Station. Therefore, only a cursory discussion of these items is included in this report. The analyses presented include a brief summary of each test, a comparison of the test results with design predictions, and an evaluation of the results.

The Surry Unit 1 Cycle 28 startup physics tests results and evaluation sheets are included as an appendix to provide additional information on the startup test results. Each data sheet provides the following information: 1) test identification, 2) test results, 3) acceptance criteria and whether it was met (if applicable),. 4) date and time of the test, and 5) preparer I reviewer initials. These sheets provide a compact summary of the startup test results in a consistent format. The entries for the design values were based on calculations performed by Dominion's Nuclear Engineering and Fuel Group. The acceptance criteria are based on design tolerances or applicable Technical Specifications and COLR Limits.

SECTION 1 -

INTRODUCTION AND

SUMMARY

Serial No.17-017 Docket No. 50-280 Enclosure On October 22, 2016, Unit No. 1 of Surry Power Station completed Cycle 27 and began refueling [Ref.

1 1]. During this refueling, 64 of the 157 fuel assemblies in the core were replaced with fresh Batch Sl/30 assemblies [Ref. 8]. The Surry 1 Cycle 28 (S1C28) core consists of eight sub-batches of fuel: three fresh batches (Sl/30A, Sl/30B and Sl/30C), three once-burned batches (Sl/29A, Sl/29B and Sl/29C), and two twice-burned batches (Sl/28A and Sl/28C).

SlC28 utilizes the 15x15 Upgrade (Upgrade) Fuel Design for all but eight of the fuel assemblies.

The remaining eight assemblies are Lead Test Assemblies (LTAs) of the AREVA AGORA-SA-I (AGO RA) design that are being loaded for their first cycle of irradiation [Ref. l].

Surry 1 batches 28, 29, 30A and 30B are of the Westinghouse Upgrade fuel design, which includes ZIRLO (I-spring) structural mid grids with balanced mixing vane pattern, three ZIRLO Intermediate Flow Mixing * (IFM) grids, "tube-in-tube" guide thimbles, the use of optimized ZIRLO fuel clad that improves corrosion resistance and oxidation *of the bottom portion of the fuel clad to improve debris resistance, Robust Protective Grids (RPG) and

\\

modified Debris Filter Bottom Nozzles (mDFBN). In addition, Sµrry 1 batches 29, 30A and 30B utilize the Westinghouse Integral Nozzle (WIN) top nozzle design [Ref. 8].

The fresh Upgrade fuel uses Westinghouse's Integral Fuel Burnable Absorber (IFBA) product as the burnable absorber. The IFBA design involves the application of a thin coating of ZrB2 on the fuel pellet surface during fabrication. Pellets with the IFBA coating are placed in specific symmetric patterns in each fresh assembly, typically affecting from 16 to 148 rods per assembly. The top and bottom 6 inches of the fuel pellet stack in the IFBA rods will contain pellets that have no IFBA coating, and have a hole in the center (annular). This additional void space helps accommodate the helium gas that accumulates from neutron absorption in ZrB2.

IFBA rods generate more internal gas during operation because neutron absorption in the ZrB2 coating creates helium gas in addition to the fission gas created during irradiation of the fuel.

Therefore, the initial pressure is set lower so the internal pressure early in lifetime may be lower

[Ref. SJ.

Page 6of46

Serial No.17-017 Docket No. 50-280 Enclosure Surry 1 batch 30C is of the AREVA AGORA fuel design.

The top grids of the assemblies are a High Thermal Performance (HTP) design fabricated from MS material. The mid-grids are AFA-3G vaned mixing grids, which are bimetallic grids utilizing MS strips and Inconel 718 springs. The mid-span mixing grids (MSMG) are MS vaned mixing grids placed on spans 3 through S on the assembly. The MSMG are similar to the IFM grids used in the other batches of this cycle and are located at approximately the same elevations as the IFMs. The bottom grid is an Inconel 718 HMP (High Mechanical Performance) grid. The fuel rod cladding is composed of MS material, and the guide tubes and instrument tubes are composed of Q 12 (zirconium alloy) and are of the MONOBLOC design [Ref. 1].

The AREVA AGORA LTAs utilize gadolinia (Gd203) as a burnable poison integral to the fuel. Each LTA contains 28 gadolinia rods, twelve at 12% and sixteen at 6%, with 6-inch cutback regions at the top and bottom of the fuel. The cutback regions are the same enrichment as non-gadolinia rocis.

The gadonlinia rods are subject to the S:l enrichment penalty (S%

reduction in U-23S for each weight percent of gadolinia) from the nominal enrichment.

Cycle 28 loads the secondary source assemblies (SSAs) in core locations H04 and H12 to improve Source Range Detector respons~. Each assembly consists of six source rods containing antimony and beryllium pellets encapsulated in a double layer of stainless steel cladding. There

  • are no thimble plugging devices in S1C28.. The cycle design report [Ref. 1] provides a more detailed description of the Cycle 28 core.

The SI C28 full core loading plan [Ref. 8 and Ref. I i] is shown in Figure I. I, and the beginning of cycle fuel assembly burnups [Ref. 6] are showr,i in Figure I.2. The incore moveable detector locations used for the flux map analyses [Ref. 7] are identified in Figure 1.3. Figure I.4 identifies the location and number of control rods in the Cycle 28 core [Ref. I].

According to the Startup Physics logs, the Cycle 28 core achieved initial criticality on November 10, 2016 at lS:SO [Ref. 14]. Prior to and following criticality, startup physics tests were performed as outlined in Table 1.1. This cycle used the Reactivity Measurement and Analysis System (RMAS) to perform startup physics testing. Note that RMAS v.7 [Ref. 9] was Page 7 of 46

Serial No.17-017 Docket No. 50-280 Enclosure used for S 1 C28 Startup Physics Testing. The tests performed are the same as in previous cycles.

A summary of the test results follows.

The measured drop time of each control rod was within the 2.40 second Technical Specification [Ref. 4] limit, as well as the 1.68 second 15x15 Upgrade Fuel administrative limit

[Ref. 1 O]. All control rods are located in Upgrade fuel assemblies.

Individual control rod bank worths were measured using the rod swap technique [Ref. 2].

For the purpose of this test, a bank was defined as 'fully inserted' when it was 2 steps off the bottom of the core [Ref. 13]. The sum of the individual measured control rod bank worths was within -1.9% of the design prediction. The referei{ce bank (Control Bank B) worth was within

-0.3% of its design prediction. Control rod banks with design predictions greater than 600 pcm were within -3.6% of the design predictions. For individual banks worth 600 pcm or less (only Control Bank A fits this category), the difference was within -6 pcm of the design prediction.

These results are within the design tolerances of +/-15% for individual banks worth more than 600 pcm (+/- 10% for the reference bank worth), +/- 100 pcm for individual banks. worth 600 pcm or less, and +/-10% for the sum of the individual control rod bank worths.

Measured critical boron concentrations for two control bank configurations, all rods out (ARO) and Reference Bank (B-bank) in, were within the design tolerances and the Technical Specification criterion [Ref. 4] that the overall core reactivity balance shall be within +/- 1 % ~

of the design prediction. The boron worth coefficient measurement (the differential boron worth, DBW) was within+ 1.3% of the design prediction, which is within the design tolerance of+/- 10%.

The measured isothermal temperature coefficient (ITC) for the ARO configuration was within +0.293 pcm/°F of the design prediction. This result is within the design tolerance of +/-2.0 pcml°F [Ref. 14].

The zero power physics testing-results were all within the criteria established in Reference 18 permitting the first flux map to be performed up to 50% power (versus 30% power if the criteria were not met).

Page 8 of 46

Serial No.17-017 Docket No. 50-280 Enclosure Core power distributions were within established design tolerances. The measured assembly power distributions were within +/-5.3% of the design predictions, where a 5.3%

maximum difference occurred in the 99.80% power map. The heat flux hot channel factors, F Q(Z), and enthalpy rise hot channel factors, F~, were within the limits of the COLR [Ref. 8].

All power flux maps were within the maximum incore power tilt design tolerance of 2% (QPTR

.:s 1.02).

The total RCS Flow was successfully verified as being greater than 273,000 gpm and greater than the limit in the COLR (274000 gpm), as required by Surry Technical Specifications

[Ref. 4]. The total RCS Flow at nominal conditions was measured as 289,888 gpm.

In summary, all startup physics test results were acceptable. Detailed results, specific design tolerances and acceptance criteria for each measurement are presented in the following sections of this report.

CONTROL ROD DROP TIME MEASUREMENTS The drop time of each control rod was measured at hot shutdown (HSD) with three reactor coolant pumps in operation (full flow) and with Tave greater than or equal to 530 °F per 1-NPT-RX-O 14. This verified that the time to entry of a rod into the dashpot region was less than or equfil to the maximum allowed by Technical Specification 3.12.C.1 [Ref. 4].

Surry Unit 1 Cycle 28 used the Rod Drop Measurement Instrument (RDMI) to gather and analyze the rod drop data [Ref. 12]. The methodology acquires data using the secondary RPI coil terminals (/3 & 14) on the Computer Enhanced Rod Position Indication (CERPI) racks for each rod. Data is immediately saved to a comma-separated value file.

It is noted that rods were dropped twice due to an issue with rod N-07 (SA-Bank); the first drop was for all rods except N-07 and the second drop was for only SA-Bank. Prior to the first drop, N-07 was noted ~o be on the bottom of the core due to a blown lift coil fuse. After this fuse was replaced, SA-Bank was dropped in order to obtain the drop time for N-07. For SA-Bank, the reported rod drop times for all rods, except N-07, were from the first drop as the second drop was for evaluation of N-07. For the other SA-Bank rods, it was noted that the second drop had a similar shape and time when compared to the first drop with an increased signal magnitude.

A typical rod drop trace for S 1 C28 is shown in Figure 2.1. The measured drop time for each control rod is recorded on Figure 2.2. The slowest, fastest and average drop times are summarized in Table 2.1. Figure 2.3 shows slowest, fastest, and average drop times for Surry 1 cycles 18-28. Technical Specification 3.12.C.1 [Ref. 4] specifies a maximum rod drop time to dashpot entry of 2.4 seconds for all rods. It is noted that the AREVA fuel assemblies are not loaded in rodded core locations. These test results satisfied this Technical Specification limit, as well as the 15x15 Upgrade administrative limit [Ref. 10] of 1.68 seconds. In addition, rod bounce was observed at the end of each trace demonstrating that no control rod stuck in the dashpot region. The fastest and average rod drop times did not change from S 1 C27 but the slowest rod time increased by 0.01 seconds.

CONTROL ROD BANK WORTH MEASUREMENTS Control rod bank worths were measured for the control and shutdown banks using the rod swap technique [Ref. 2]. The initial step of the rod swap method diluted the predicted most reactive control rod bank (hereafter referred to as the reference bank) into the core and measured its reactivity worth using conventional test techniques. The reactivity changes resulting from the reference bank movements were recorded continuously by the reactivity computer and were used to determine the differential and integral worth of the reference bank. For Cycle 28, Control Bank B was used as the reference bank. Surry 1 targeted a dilution rate of 1100 pcm/hr for the reference bank measurement.

During a previous startup physics testing campaign, a control rod became stuck on the bottom eventually forcing a reactor trip to fix the problem. The solution to this issue for startup physics testing was to avoid requiring control rods to be manually inserted to 0 steps. To accomplish this, an evaluation of the startup physics testing process was performed [Ref. 13],

concluding that the definition of fully inserted for control rod positions used in startup physics testing could be changed from 0 steps withdrawn to a range of 0 to 2 steps withdrawn. The S 1 C28 startup physics testing campaign used 2 steps withdrawn for all conditions requiring control rods to be manually fully inserted.

After completion of the reference bank reactivity worth measurement, the reactor coolant system temperature and boron concentration were stabilized with the reactor near critical and the reference bank near its full insertion. Initial statepoint data (core reactivity and moderator temperature) for the rod swap maneuver were next obtained with the reference bank at its fully inserted position and all other banks fully withdrawn.

Test bank swaps proceed in sequential order from the bank with the smallest worth to the bank with the largest worth. The second test bank should have a predicted worth higher than the first bank in order to ensure the first bank will be moved fully out before the second bank is fully inserted. The rod swap maneuver was performed by withdrawing the previous test bank (or reference bank for the first maneuver) several steps and then inserting the next test bank to balance the reactivity of the bank withdrawal. This sequence was repeated until the previous test Page 20 of 46

Serial No.17-017 Docket No. 50-280 Enclosure bank was fully withdrawn and the current test bank was nearly inserted. The next step was to swap the rest of the test bank in by balancing the reactivity with the withdrawal of the reference bank, until the test bank was fully inserted and the reference bank was positioned such that the core was near the initial statepoint condition. This measured critical position (MCP) of the reference bank with the test bank fully inserted was used to determine the integral reactivity worth of the test bank.

The core reactivity, moderator temperature, and differential worth of the reference bank were recorded with the reference bank at the MCP. The rod swap maneuver was repeated for all test banks. Note that after the final test bank was fully inserted, the test bank was swapped with the reference bank until the reference bank was fully inserted and the last test bank was fully withdrawn. Here the final statepoint data for the rod swap maneuver was obtained (core reactivity and moderator temperature) in order to verify the reactivity drift was within procedural limitations for the rod swap test.

A summary of the test results is provided in Table 3.1. As shown in this table and the Startup Physics Test Summary Sheets in the Appendix, the individual measured bank worths for the control and shutdown banks were within the design tolerance of +/- 10% for the reference bank, +/- 15% for test banks of worth greater than 600 pcm, and +/- 100 pcm for test banks of worth less than or equal to 600 pcm. The sum of the individual measured rod bank worths was within

-1.9% of the design prediction. This is well within the design tolerance of +/- 10% for the sum of the individual control rod bank worths.

The integral and differential reactivity worths of the reference bank (Control Bank B) are shown in Figures 3.1 and 3.2, respectively. The design predictions [Ref. 1] and the measured data are plotted together in order to illustrate their agreement. In summary, the measured rod worth values were found to be satisfactory.

BORON ENDPOINT AND WORTH MEASUREMENTS Boron Endpoint With the reactor critical. at hot zero power (HZP), reactor coolant system (RCS) boron concentrations were measured at selected rod bank configurations to enable a direct comparison of measured boron endpoints with design predictions. For each critical boron concentration measurement, the RCS conditions were stabilized with the control banks at or very near a selected endpoint position. Adjustments to the measured critical boron concentration values were made to account for off-nominal control rod position and moderator temperature, as necessary.

The results of these measurements are given in Table 4.1. As shown in this table and in the Startup Physics Test Summary Sheets included in the Appendix, the measured critical boron endpoint values were within their respective design tolerances. The ARO endpoint comparison to the predicted value met the requirements of Technical Specification 4.10.A [Ref. 4] regarding core reactivity balance. In summary, the boron endpoint results were satisfactory.

Boron Worth Coefficient The measured boron endpoint values provide stable statepoint data from which the boron worth coefficient or differential boron worth (DBW) was determined. By relating each endpoint concentration to the integrated rod worth present in the core at the time of the endpoint measurement, the value 'of the DBW over the range of boron endpoint concentr~tions was obtained.

A summary of the measured and predicted DBW is shown in Table 4.2. As indicated in this table and in the Appendix, the measured DBW was well within the design tolerance of

+/-10%. In summary, the measured boron worth coefficient was satisfactory.

Serial No.17-017 Docket No. 50-280 Enclosure SECTION 5 -TEMPERATURE COEFFICIENT MEASUREMENT The isothermal temperature coefficient (ITC) at the ARO condition is measured by controlling the RCS temperature with the steam dump valves to the condenser, establishing a constant heatup or cooldown rate by adjusting feed and letdown flow rates, and monitoring the resulting reactivity changes on the reactivity computer.

Reactivity was measured during the RCS heat up of 3.00 °F, followed by the RCS cool down of 3.04 °F. Reactivity and temperature data were taken from the reactivity computer. Using the statepoint method, the temperature coefficient was determined by dividing the change* in reactivity by the change iri RCS temperature.,

The predicted and measured ITC values are compared in Table 5.1. As can be seen from this summary and from the Startup Physics Test Summary Sheet in the Appendix, the measured isothermal temperature coefficient value was within the design tolerance of +/-2 pcm/°F. The calculated moderator temperature coefficient (MTC), which is calculated using a measured ITC of -2.325 pcm!°F, a predicted* doppler temperature coefficient (DTC) of -1.83 pcm/ °F, and a measurement uncertainty of +0.5 pcm/ °F, is 0.005 pcm/ °F. It thus satisfies the COLR criteria

[Ref. 8] that indicates MTC at HZP be less than or equal to +6.0 pcm/°F.

POWER DISTRIBUTION MEASUREMENTS The core power distributions were measured using the moveable incore detector flux mapping system. This system consists of five fission chamber detectors that traverse fuel assembly instrumentation thimbles in up to 50 core locations. Figure 1.3 shows the available locations monitored by the moveable detectors for Cycle 28 power ascension flux maps. For each traverse, the detector voltage output is continuously monitored on a recorder, and scanned for 610 discrete axial points. Full core, three-dimensional power distributions are determined from this data using a Dominion-modified version of the Combustion Engineering computer program, CEBRZ/CECOR [Ref. 3, Ref. 15]. CECOR couples the measured voltages with predetermined analytic power-to-flux ratios in order to determine the power distribution for the whole core. The CECOR GUI (Ref. 16) was used as an interface to CEBRZ and CECOR.

A list of the full-core flux maps [Ref. 7] taken during the startup test program and the measured values of the important power distribution parameters are provided in Table 6.1. A comparison of these measured values with their COLR limits is given in Table 6.2. Flux map 1 was taken at 46.30% power to verify the radial power distribution (RPD) predictions at low power and to ensure there is no evidence that supports the possibility of a core misload or dropped rod. Figure 6.1 shows the measured RPDs from this flux map. Flux maps 2 and 3 were taken at 70.04% and 99.80% power, respectively, with different control rod configurations.

These flux maps were taken to check at-power design predictions and to measure core power distributions at various operating conditions. The radial power distributions for these maps are.

given in Figures 6.2 and 6.3.

The radial power distributions for the maps given in Figures 6.1, 6.2 and 6.3 show the measured relative assembly power values deviated from the design predictions by at most +/-4.1 %

in the 46.30% power map, +/-3.0% in the 70.04% power map, and +/-5.3%.in the 99.80% power map. The maximum average quadrant power tilts for the three maps were +0.78%, +0.54% and

+0.41 %, respectively. These power tilts are within the design tolerance of2%.

Page 30 of 46

Serial No.17-017 Docket No. 50-280 Enclosure The measured Fq(z) and F~ peaking factor values for the at-power flux maps were within the limits of the COLR [Ref. 8]. Flux Maps 1, 2 and 3 were used for power range detector calibration or to confirm existing calibrations.

In conclusion, the power distribution measurement results are considered acceptable with respect to the design tolerances, the accident analysis acceptance criteria, and the COLR [Ref. 8].

It is therefore anticipated that the core will continue to operate safely throughout Cycle 28.

These flux maps were used for power range detector calibration or were used to confirm existing calibrations.

(1) FQ(Z) includes a total uncertainty of8%.

(2) F:ii includes no uncertainty.

(3) CORE TILT - defined as the average quadrant power tilt from CECOR. "Max" refers to the maximum positive core tilt (QPTR > 1.0000).

CONCLUSIONS Serial No.17-017 Docket No. 50-280 Enclosure Table 7.1 summarizes the results associated with Surry Unit 1 Cycle 28 startup physics testing program. As noted herein, all test results were acceptable and within associated design tolerances, Technical Specification limits, or COLR limits. The AREVA AGORA LTAs show no signs of anomalous behavior and are performing as expected. It is anticipated, based on the results associated with the S 1 C28 startup physics testing program, that the Surry 1 core will continue to operate safely throughout Cycle 28.
