PREFACE This report presents the analysis and evaluation of the physics tests which were performed to verify that the North Anna Unit 1, Cycle 12 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.

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 Anna 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 12 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 conditions (design), 3) test conditions (actual), 4) test results, 5) acceptance criteria, and 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 NE-1073 NIC12 Startup Physics Tests Report Page 5 of 57

I I

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 tests.

l-INTRODUCTION AND

SUMMARY

4 i

On February 11, 1996 Unit No. 1 of the North Anna Power Station I

shutdown for its eleventh refueling. During this shutdown, 73 of the 157

-fuel assemblies in the core were replaced with 64 fresh fuel assemblies,

~ 1 once-burned fuel assembly, and 8 twice-burned fuel assemblies.

The twelfth cycle core consists of 8 sub-batches of fuel:

three once-burned batches, two from Cycle 11 (batches 13A and 13B) and one from North Anna i

Unit ' 2, Cycle 9 (batch N2/11B); three twice-burned batches, two from-Cycles 10 and 11 (batches 12A and 12B) and one from Cycles 9 and 10 (batch I

11B), and two' fresh batches (batches 14A and 14B). Batches N1/11, N1/12 and N2/11 have top and bottom grids of Inconel-718 while the inner six grids are made of Zircaloy-4. Batches N1/13 and N1/14 have top and bottom grids of Inconel-718, six inner grids made of ZIRLO (ZIRLO provides improved corrosion resistance and dimensional stability under irradiation 4

relative to Zircaloy-4 components), and one Inconel-718 protective grid ll l

placed below the fuel and above the bottom nozzle for debris resistance.

Cycle 12, similar to Cycle 11, incorporated the burnable poison rod design made of B C in Alumina, which is available in various enrichments 4

k of B C.

There are no thimble plugging devices inserted in N1C12.

Due 4

to the conversion of the core barrel by pass flow from downflow to upflow during the NIC11/NIC12 refueling outage, no baffle clips were necessary

?

In N1C12 (to help protect against baffle jetting degradation). There are 28 vibration suppression damping assemblies inserted in peripherally i

NE-1073 N1C12 Startup Physics Tests Report Page 7 of 57

g Il loaded fuel assemblies that have non-rotated Zircaloy-4 grids. Reference 1 provides a more detailed description of the Cycle 12 core.

The core loading pattern and the design parameters for each sub-batch E'

are shown in Figure 1.1.

Fuel assembly burnups are given in Figure 1.2 and documented in Reference 6.

The available incore moveable detector locations used for the flux map analyses are identified in Figure 1.3.

Figure 1.4 identifies the location and number of burnable poison rods and source assemblies for Cycle 12, and Figure 1.5 identifies the location I

and number of control rods in the Cycle 12 core.

On March 10, 1996 at 23:51, the Cycle 12 core achieved initial criticality. Following criticality, startup physics tests were performed as outlined in Table 1.1.

A summary of the results of - these tests follows:

1.

The measured drop time of each control rod was within the 2.7 second limit of Technical Specification 3.1.3.4.

l 2.

Individual control rod bank worths were measured using the rod swap technique and the results were within 2.9% of the design 2

predictions. The sum of the individual measured control rod bank worths was within 1.9% of the design prediction.

These results are within the design tolerance of 115% for individual bank worths

( 10% for the rod swap reference bank worth) and the design tolerance of 10% for the sum of the individual control rod bank worths.

Il 3.

Measured critical boron concentrations for two control bank configurations were within 6 ppm of the design predictions. These NE-1073 N1C12 Startup Physics Tests Report Ppge 8 of 57

results were within the design tolerances and also met the Technical Specification 4.1.1.1.2 criterion that the overall core reactivity balance shall be within 11% Ak/k of the design prediction.

4.

The boron worth coefficient measurement was within 0.3% of the design prediction, which is within the design tolerance of 110%.

5.

The measured isothermal temperature coefficient (ITC) for the all-rods-out (ARO) configuration was within 0.60 pcm/'F of the design prediction.

This result is within the design tolerance

(

of 13 pcm/'F.

The measured ITC of -2.60 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 +3.75 pcm/'F.

(

6.

Mode 1 (see Reference 4) core power distributions were within established design tolerances.

Generally, the measured cure power distribution was within 1.5% 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, respectively.

SECTION 2 CONTROL ROD DROP TIME MEASUREMENTS I

The drop time of each control rod was measured at hot full-flow reactor coolant 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 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.

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 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 time. This procedure was repeated for each control rod.

As shown on the sample rod drop trace in Figure 2.1, the initiation of the rod drop 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 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.

I I

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 Specificat'.on 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, red bounce was observed at the end of each trace which demonstrated that no control rod stuck in the dashpot region.

1 CONTROL ROD BANK WORTH MEASUREMENTS Control rod bank worths were measured for the control and shutdown banks using the rod swap technique ***.

The initial step of the rod swap I

method diluted the predicted most reactive control rod bank (hereaf ter 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 12, Control Bank B was usec 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 Il 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 i

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 determine NE-1073 NIC12 Startup Physics Tests Report Page 22 of 57

t J

J the integral reactivity worth of the test bank.

The core reactivity, moderator temperature, and the differential worth of the reference bank I

were recorded with the reference bank at th 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 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 (110% for the reference bank,115% for test banks of worth greater than 600 pca, and 1100 pcm for test banks of worth less than or equal to 600 pcm.) The sum i

of the individual measwed rod bank worths was within 1.9% of the design prediction. This is well within the design tolerance of 110% for the sum

)

.ot' 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 and the seasured data are plotted together in order to illustrate their agreement. In summary, the measured rod worth values were satisfactory.

SECTION 4 BORON ENDPOINT AND WORTH MEASUREMENTS 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 concentration measurement, the RCS conditions were stabilized with the control banks ac 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 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 relating each endpoint concentration to the integrated rod worth present in the core at the time of the endpoint measurement,

-NE-1073 N1C12 Startup Physics Tests Report Page 27 of 57

I the value of the DBW over the range of boron endpoint concentrations was obtained.

A plot of the boron concentration versus inserted control rod worth is shown in Figure 4.1.

As indicated in this figure and in tha Appendix, the measured DBW was -6.70 pen /ppe. This is within 0.3% of the predicted value of -6.68 pcm/ ppa and is well within the design tolerance of 10%.

In summary, the measured boron worth coefficient was satisfactory.

4 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 monitoring the resulting reactivity changes on the reactivity computer.

Reactivity was measured during the RCS cooldown of 3.4'F and RCS heatup 4

of 3.5'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 i

plotted reactivity versus temperature, confirmed the statepoint method d

in calculating the measured ITC.

The predicted and measured isothermal temperature coefficient values are 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 3 pcm/'F. The moderator temperature coefficient was determined to be -0.85 pcm/'F which met the requirements of COLR Section 2.1.1.

In summary, the measured result was satisfactory.

l SECTION 6 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 which traverse fuel assembly instrumentation thimbles in up to 50 core locations.

Figure 1.3 shows the available locations monitored by the moveable detectors for the ramp to full power flux maps for Cycle 12.

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 distributions are determined from this data using a Virginia Power modified version of the Combustion Engineering computer program, CECOR. CECOR couples the measured voltages with predetermined 8

analytic power-to-flux ratios in order to determine the power j

distribution for the whole core.

A list of the full-core flux maps taken during the startup test program and the 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 map 1 was taken at 30% 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 74% and 100% power, respectively, with dif ferent control rod configurations. These flux maps were taken to check at power design predictions and to measure core power distributions at i

various operating conditions.

The radial power distributions for these I

maps are given in Figures 6.2 and 6.3.

The radial power distributions NE-1073 N1C12 Startup Physics Tests Report Page 33 of 57

I I:

for the maps given in Figures 6.1, 6.2, and 6.3 show that the measured i1 relative assembly power values were generally within 1.57. 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 used to perform power range detector calibrations (flux maps 1 and 2 verified that the existing calibrati'n was satisfactory, thus no adjustments to the power range detector calibration were required). 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 12.
