PREFACE This report presents the analysis and evaluation of the physics tests which were performed to verify that the North Anna Unit 1, Cycle 14 core could be operated safely, and makes an initial evaluation of the performance of the core, it is not the intent of this report to discuss the particular methods of testing or to present the detailed data taken. l 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 the North Arma 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 North Anna Unit 1, Cycle 14 startup physics tests results and evaluation sheets are included as an appendix to provide additional information on the startup test j results. Each data sheet provides the following information: 1) test identification,2) test conditions (design), 3) test conditions (actual),4) test reaults, 5) acceptance criteria, and 1

6) comments concerning the test. These sheets provide a compact summary of the startup test results in a consistent format. The design test conditions and design values (at design conditions) of the measured parameters were completed prior to the startup physics testing. The entries for the design values were based on the calculations performed by Virginia Electric and Power Company's Nuclear Analysis and Fuel Group' During the tests, the data sheets were used as guidelines both to verify that the proper test conditions were met and to facilitate the preliminary comparison between measured and predicted test results, thus enabling a quick identification of possible problems occuring during the I

tests. NE-1176 NIC14 Startup Physics Tests Report Page 5 of 57

1 E l SECTION 1 INTRODUCTION AND

SUMMARY

I On September 13,1998 Unit No. I of the North Anna Power Station shutdown for I its thirteenth 1-fueling. During this shutdown,65 of the 157 fuel assemblies in the core were replaced with 64 fresh assemblies and one once-burned assembly. The Cycle 14 core consists of 9 sub-batches of fuel: four once-burned batches, three batches from Cycle 13 (batches 15A,15B, and 15C) and one batch from Cycle 7 (batch 9B); three twice-bumed batches, two batches from Cycles 12 and 13 (batches 14A and 14B) and one batch from Cycles 4 and 13 (batch 6); and two fresh batches (batches 16A and 16B). The fresh batches are of a similar design to the Westinghouse batch 15 fuel (fresh fuel in Cycle 13) except for a reduction in the holddown spring force. I Special features of the NICl4 reload core include: second cycle of operation for the four lead test assemblies (LTAs) manufactured by Framatome Cogema Fuels (FCF), burnable poison inserts with a 127.2" axial absorber region, five reconstituted fuel assemblies, and the incorporation of vibration suppression damping assemblies (VSDAs) to prevent grid to rod fretting caused by assembly vibration. The four LTAs are of a similar design to the resident Westinghouse fuel assemblies with the following exceptions; use of different zirconium-based alloys for the fuel rod cladding and fuel assembly structural tubing, some grid dimensional differences, the use of three mid-spanI Page 6 cf 57 NE-1176 N1C14 Startup Physics Tests Report

mixing grids, a higher nominal fuel pellet density, a reconstitutable quick release top nozzle design and a fine mesh debris filter bottom nozzle, and the use of FCF's axially " floating" grid design. l 1 Cycle 14 marks the first use of a BPRA product with an active absorber length of 127.2 inches. The 127.2 inch design is similar to the 126 inch design used in Cycle 13 with the only exception being the location of the bottom of the absorber. The 127.2 inch design is located such that the bottom of the absorber is approximately 9 inches above the bottom of the active fuel length and the top of the absorber is approximately 7.8 inches below the top of the active fuel length relative to the NAIF /P+Z fuel design. The BP assembly and pellet design are the same for both products. Cycle 14, similar to Cycle 13, incorporated the burnable poison rod design made l of B4C in Alumina, which is available in various enrichments of B4C There are no ' thimble plugging devices or secondary sources inserted in NICl4. There are 24 vibration suppression damping assemblies inserted in peripherally loaded fuel assemblies to help prevent grid to rod fretting caused by assembly vibration. Reference 1 provides a more detailed description of the Cycle 14 core. I The core loading pattern and the design parameters for each sub-batch are shown in Figure 1.1. Beginning of cycle fuel assembly bumups are given in Figure 1.2 and documented in Reference 6.

I the flux map analyses are identified in Figure 1.3. Figure 1.4 identifies the location and number of burnable poison rods and VSDAs for Cycle 14, and Figure 1.5 identifies the location and n imber of control rods in the Cycle 14 core. l On October 7,1998 at 15:04, the Cycle 14 core achieved initial criticality. Prior to and following criticality, startup physics tests were perfonned as outlined in Table 1.1. A summary of the results of these tests follows: The measured drop time of each control rod was within the 2.7 second limit of Technical Specification 3.1.3.4, I Individual control rod bank worths were measured using the rod swap The sum of the individual measured control rod bank worths was within 25 technique 2.02% of the design prediction and the reference bank worth was within 1.02% of'its design prediction. The other control rod banks were within 7.17% or 29.3 pcm of the design predictions. These results are within the design tolerances of 215% for individual banks worth more than 600 pcm (210% for the rod swao reference bank worth), 2 l00 pcm for individual banks worth 600 pcm or less, and 210% for the sum of the individual L control rod bank worths. Measured critical boron concentrations for two control bank configurations were within 8 ppm of the design predictions. These results were within the design tolerances I Page 8 of 57 NE-1176 NIC14 Startup Physics Tests Report

1 and also met the Technical Specification 4.1.1.1.2 criterion that the overall core reactivity balance shall be within 1% Ak/k of the design prediction. 2 The boron worth coefficient measurement was within 5.4% of the design prediction, which is within the design tolerance of 210%. The measured isothermal temperature coefficient (lTC) for the all-rods-out (ARO) configuration was within 0.14 pcm/ F of the design prediction. This result is within the design tolerance of 23 pcm/*F. The measured ITC of -2.35 pcm/ F meets the Core Operating Limits Report (COLR) 2.1.1 criterion that the moderator temperature coefficient (MTC) be less than or equal to +6.0 pcm/ F. When the Doppler temperature coefficient and a 0.5 pcm/ F uncertainty are accounted for in the MTC limit, the MTC requirement is satisfied as long as the ITC is less than or equal to +3.76 pcm/ F. I Mode 1 (see Reference 4) core power distributions were within established design tolerances. Generally, the measuied core power distributions were within 2.1% of the design predictions. The heat flux hot channel factors. F-Q(Z), and enthalpy rise hot channel factors, F-DH(N), were within the limits of COLR Sections 2.5.1 and 2.6, I respectively. l r In summary, all startup physics test results were acceptable.

SECTION 2 CONTROL ROD DROP TIME MEASUREMENTS I The drop time of each control rod was measured at hot full-flow reactor coolant I system (RCS) conditions in order to verify that the time from initiation of the rod drop to the entry of the rod into the dashpot was less than or equal to the maximum allowed by 4 Technical Specification 3.1.3.4. The control rod drop times were measured in Mode 3 with the RCS Tavg above 500 F and all reactor coolant pumps operating. I The rod drop times were measured by withdrawing a rod bank 229 steps and then removing the moveable gripper coil fuse and stationary gripper coil fuse for the particular I rod of the bank to be dropped. This allowed the rod to drop into the core as it would during a plant trip. The stationary gripper coil voltage and the Individual Rod Position Indication (IRPI) primary coil voltage signals were recorded to determine the rod drop i time. This procedure was repeated for each control rod. I l As shown on the sample rod drop trace in Figure 2.1, *he initiation of the rod drop i is indicated by the decay of the stationary gripper coil voltage when the stationary gripper coil fuse is removed. As the rod drops. a voltage is induced in the IRPI primary coil. The magnitude of this voltage is a function of control rod velocity. As the rod enters the dashpot region of the guide tube, its velocity slows causing a voltage decrease in the IRPI NE-1176 N1Cl4 Startup Physics Tests Report Page 16 of 57 l B

coil. This voltage reaches a minimum when the rod reaches the bottom of the dashpot. Subsequent variations in the trace are caused by rod bouncing. The measured drop times for each control rod are recorded on Figure 2.2. The slowest, fastest, and average drop times are summarized in Table 2.1. Technical Specification 3.1.3.4 specifies a maximum rod drop time from loss of stationary gripper coil voltage to dashpot entry of 2.7 seconds with the RCS at hot, full flow conditions. These test results satisfied this limit. In addition, rod bounce was observed at the end of each trace which demonstrated that no control rod stuck in the dashpot region. l l l l l i NE-1176 N1C14 Startup Physics Tests Report Page 17 of 57

SECTION 3 CONTROL ROD BANK WORTH MEASUREMENTS Control rod bank worths were measured for the control and shutdown banks using 2 the rod swap technique #, 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 14, Control Bank B was used as the reference bank. After the 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 fully inserted. Initial statepoint data for the rod swap maneuver were obtained with the reference bank at its fully inserted position and all other banks fully withdrawn, recording the core reactivity and moderator temperature. From this point, a rod swap maneuver was performed by withdrawing the reference bank several steps and then inserting one of the other control rod banks (i.e., a test bank) to balance the reactivity of the reference bank withdrawal. This sequence was repeated until the test bank was fully inserted and the reference bank was positioned such that the core was just critical or near the initial statepoint condition. This measured critical position (MCP) of the reference bank with the test bank fully inserted was used to I NE-1176 N1Cl4 Startup Physics Tests Report Page 21 of 57

I determine the integral reactivity worth of the test bank. The core reactivity, moderator temperature, and the differential worth of the reference bank were recorded with the reference bank at the MCP. The rod swap maneuver then was repeated in reverse such that the reference bank again was fully inserted with the test bank fully withdrawn from the core. This rod swap process was then repeated for each of the other control and E shutdown banks. A summary of the test results is given in Table 3.1. As shown in this table and the Startup Physics Test Results and Evaluation Sheets given in the Appendix, the individual measured bank worths for the control and shutdown banks were within the design tolerance (210% for the reference bank,215% for test banks of worth greater than 600 pcm, and 2100 pcm for test banks of worth less than or equal to 600 pcm.) The sum the individual measured rod bank worths was within 2.02% of the design prediction. I This is well within the design tolerance of 210% for the sum of the individual control rod bank worths. I' 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 and the measured data are plotted together in order to illustrate their agreement. In summary, the measured rod worth values were satisfactory.

I SECTION 4 BORON ENDPOINT AND WORTH MEASUREMENTS I Boron Endpoint With the reactor critical at hot zero power, 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 l concentration measurement, the RCS conditions were r ilized with the control banks at E 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, if necessary. The results of these measurements are given in Table 4.1. As shown in this table and in the Startup Physics Test Results and Evaluation Sheets given 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 1 Specification 4.1.1.1.2 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 I relating each endpoint concentration to the integrated rod worth present in the core at the NE-1176 N1C14 Startup Physics Tests Report Page 26 of 57 3 i

time 'of the endpoint measurement, the value of the DBW over the range of boron .- endpoint concentrations 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. 1 i f 1 NE-1176 N1C14 Startup Physics Tests Report Page 27 of 57

I, SECTION 5 TEMPERATURE COEFFICIENT MEASUREMENT I The isothermal temperature coefficient (ITC) at the all-rods-out condition is measured by controlling the reactor coolant system (RCS) temperature with the steam dump valves to the condenser, establishing a constant heatup or cooldown rate, and l monitoring the resulting reactivity changes on the reactivity computer. I Reactivity was measured during the RCS cooldown of 3.7 F and RCS heatup of 3.3 F. Reactivity and temperature data were taken from the reactivity computer and strip chart recorders. Using the statepoint method, the temperature coefficient was determined by dividing the change in reactivity by the change in RCS temperature. An X-Y plotter, which plotted reactivity versus temperature, confirmed the statepoint method in calculating the measured ITC. I values are The predicted and measured isothermal temperature coefficient compared in Table 5.1. As can be seen from this summary and from the Startup Physics Test Results and Evaluation Sheet given in the Appendix, the measured isothermal temperature. coefficient value was within the design tolerance of 23 pcm/ F. The moderator temperature coefficient was determined to be -0.61 pcm/ F which met the requirements of COLR Section 2.1.1. In summary, the measured results were I satisfactory.

SECTION 6 POWER DISTRIBUTION MEASUREMENTS I The core power distributions were measured using the moveable incore detector flux mapping system. This system consists of five fission chamber detectors which traverse fuel assembly instrumentation thimbles in up to 50 core locations. Figure 1.3 l shows the available locations monitored by the moveable detectors for the ramp to full I power flux maps for Cycle 14. For each traverse, the detector voltage output is continuously monitored on a strip chart recorder, and scanned for 61 discrete axial points by the PRODAC P-250 process computer. Full core, three-dimensional power distubutions are determined from this data using a Virginia Power modified version of 3 the Combustion Engineering computer program, CECOR. CECOR couples the measured voltages with predetermined analytic power-to-flux ratios in order to determine l the power distribution for the whole core. E A list of the full-core flux maps taken during the startup test program and the i measured values of the important power distribution parameters are given in Table 6.1. A comparison of these measured values with their COLR limits is given in Table 6.2. Flux l l 5 l map 1 was taken at 29% power to verify the radial power distribution (RPD) predictions at low power. ' Figure 6.1 shows the measured RPDs from this flux map. Flux maps 2 and 3 were taken at 71% and 100% power, respectively, with different control rod I configurations. These flux maps were taken to check at-power design predictions and to NE-1176 NIC14 Startup Physics Tests Report Page 32 of 57 I

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 that the measured relative assembly power values were generally within 2.1% of the predicted values. Further, the measured F-Q(Z) and F-DH(N) peaking factor values for the at-power flux maps were within the limits of COLR Sections 2.5.1 and 2.6, respectively. Flux maps 1, 2, and 3 were also used to perform power range detector calibrations. The flux map analyses are documented in Reference 7. In conclusion, the power distribution measurement results were considered to be acceptable with respect to the design tolerances, the accident analysis acceptance criteria, and the COLR. It is therefore anticipated that the core will continue to operate safely throughout Cycle 14. i NE-1176 N1Cl4 Startup Physics Tests Report Page 33 of 57
