PREFACE

The .purpose of this report is to present the analysis and evaluation

of the physics tests which were performed to verify that the Surry 2, Cycle 5

core could be operated safely, and to make an initial evaluation of the expected

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

test 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 Surry Power Station. Therefore, only a cursory discussion of these items

is included in this report. The analyses presented includes a brief summary of

each test, a comparison of the test results with design predictions, and an

evaluation of the results.

The Surry 2, Cycle 5 Startup Physics Tests Results and Evaluation

Sheets have been 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 of the measured parameters

were completed prior to startup physics testing. The entries for the design

values were based oµ calculations performed by Vepco's Nuclear Fuel Engineering

1 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 compari-

son between measured and predicted test results, thus enabling a quick identi-

fication of possible problems occurring during the tests. The appendix to this

report contains the final completed and approved version of the Startup Physics

Tests Results and Evaluation Sheets.

INTRODUCTION AND SUMMARY

On February 4, 1979, Unit No. 2 of the Surry Power Station was shut-

down for its fourth refueling and a steam generator replacement outage. During

this shutdown, 64 of the 157 fuel assemblies in the core were replaced with

fresh fuel assemblies. The second cycle core consists of six batches of fuel:

two once-burned batches from Cycle 4 (Batches 6Al and 6B), one tw:,ice-buined

batch that is carried over from Cycles 3 and 4 (Batch 5A), one~thrice-burned

batch that is carried over from Cycles 2, 3 and 4 (Batch 4B2), and two fresh

batches (Batches 7A and 7B). The core loading pattern and the design parameters

for each batch are shown in Figure 1.1. The core location of each fuel assembly

is identified in Figure 1.2 together with the incore instrumentation locations.

Figure 1.3 identifies the location and number of burnable poison rods in the

Cycle 5 core. Figure 1.4 identifies the location and number of control rods in

the Cycle 5 core.

On August 14, 1980, at 1208, the fifth cycle 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. ~e drop time of each control rod was confirmed to be within

the 1.8 second limit of the Technical Specifications.2

2. The reactor coolant system flow rate was confirmed to be greater

than the minimum limit specified in the Final Safety Analysis

Report. 3

3. Individual control rod bank worths for all control rod banks were

measured using the rod swap technique4 and were .. ·found ·to be. within

13. 2% of thia design predictions. The sum of. the individual c0ntrol .rod ·

bank worths was measured to be.within 3.8% of the design prediction.

1


These results are within the design tolerance of +15% for indi-

vidual 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.

4. Critical boron concentrations for two control bank configurations

were measured to be within 43 ppm of the design predictions.

These results are within the design tolerances and also met the

accident analysis acceptance criterion.

5. The boron worth coefficient was measured to be within 5.9% of

the design prediction, which is within the design tolerance of

+10% and met the accident analysis acceptance criterion.

6. Isothermal temperature coefficients for two control bank config-

urations were measured to be within 0.6 pcm/°F of the design

predictions. These results are within the design tolerance of

+3 pcm/ 8 F and also met the accident analysis acceptance criterion.

7. Core power distributions for various HZP and at-power conditions

were generally within 6% of the predicted power distributions.

For all maps, the hot channel factors were measured to be within

the limits of the Technical Specifications. Generally, all

measurement parameters met their respective design value tolerances.

All measurement parameters met their respective accident analysis

acceptance criteria.

In summ~ry, all startup physics test results were acceptable.

Detailed results, .together with specific design tolerances and acceptance

criteria for each measurement,· are presented in the appropriate sections of

this report.

CONTROL ROD DROP TIME MEASUREMENTS

The drop time of each control rod was measured at cold and at hot RCS'

conditions in order to confirm satisfactory operation and to verify that the

rod drop times were less than the maximum allowed by the Technical Specifica-

tions. The hot control rod drop time measurements were run with the RCS at hot,

full flow conditions (~547°F, ~2235 psig) and are described below.

The rod drop time measurements were performed by first withdrawing a

rod bank to its fully withdrawn position, and then removing the movable gripper

coil fuse and stationary gripper coil fuse for the test rod. This allows the

rod to drop into the core as it would in a normal plant trip. The data recorded

during this test are, the stationary gripper coil voltage, the LVDT (Linear

Variable Differential Transformer) primary coil voltage and a 60Hz timing trace which

are recorded via a visicorder. The rod drop time to the dashpot entry and to the

bottom of the dashpot are determined from this data. Figure 2.1 provides an

example of the data that is recorded during a rod drop time measurement.

As shown 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. A voltage is then induced in the LVDT primary coil as the

I I

rod drops. The magnitude of this voltage is a function of the rod velocity.

When the rod enters the dashpot section of its guide tube, the velocity slows

causing a·voltage decrease in the LVDT coil. The LVDT voltage then reaches a

minimum as the rod reaches the bottom of the dashpot. Subsequent variations in

~ the trace are caused by the rod bouncing. This procedure was repeated for each

I I I

control rod.

8


The measured drop times for each control ro·d: are recorded ·on Figure 2. 2.

The slowest, fastest and average drop times are summarized in Table 2.1.

Technical Specification 3.12.C.1 specifies a maximum rod drop time from loss of

stationary gripper coil voltage to dashpot entry of 1.8 seconds with the RCS at

hot, full flow conditions. All test results met this limit.

REACTOR COOL.ANT SYSTEM FLOW MEASUREMENT

The reactor coolant flow rate is measured in order to verify that the

minimum flow rate requirement is satisfied. The RCS flow rate is determined

using the calorimetric measurement technique. Precision calorimetric data

I (i.e., feedwater temperature, feedwater flow, and steam pressure) are obtained in order to accurately determine the secondary-side heat rate. The primary-side

I I I I I I I I I I I I I

enthalpy rise is determined from the RCS pressure and the temperature increase

associated with each RCS loop. The flow for each RCS loop is determined by

establishing a primary-side to secondary-side heat balance. Steam generator

blowdown heat loss, system heat losses, and the power produced by the reactor

coolant pumps are taken into account in the heat balance. A reactor coolant

flow measurement was performed at 100% power. This data was analyzed using

5 the RXFLOW computer code. A sunnnary of the results for this test is given in

Table 3.1. As shown by this table, the test results demonstrated that the RCS

flow limit was met.

CONTROL ROD BANK WORTH MEASUREMENTS

Control rod bank worth measurements were obtained for all control and

shutdown banks using the rod swap technique. The first step in the rod swap

procedure was to dilute the most reactive control rod bank (hereafter referred

to as the reference bank) into the core and measure its reactivity worth using

conventional test techniques. The reactivity changes resulting from the

6 reference bank movements were recorded continuously by the reactivity computer

and were used to determine the differential and integral worth of the reference

bank (Control Bank B). At the completion of the reference bank reactivity worth

measurement, the reactor coolant system temperature and boron concentration were

stabilized such that the reactor was critical with the reference bank near full

insertion. Initial statepoint data for the rod swap maneuver were obtained by

moving the reference bank to its fully inserted position and recording the core

reactivity and moderator temperature. At this point, a rod swap maneuver was

performed by withdrawing the reference bank while one of the other control rod

banks (i.e., a test bank) was inserted. The core was kept nominally critical

throughout this rod swap and the maneuver was continued until the test bank was

fully inserted and the reference bank was at the position at which the core was

just critical. This measured critical position (MCP) of the reference bank

with the test bank fully inserted is the major parameter of interest and was

used to determine the integral reactivity worth of the test bank. Statepoint

data (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 was then performed in reverse order such that the reference bank

once again was near full insertion and the test bank was once again fully withdrawn

from the core. The rod swap process was then repeated for all of the other control

rod banks (control and shutdown).

I I I I

A summary of the results for these tests is given in Table 4.1. As

shown by this table and the Startup Physics Test Results and Evaluation Sheets

given in the Appendix, the individual measured bank worths for all of the

control and shutdown banks were within the design tolerance (+10% for the

I reference bank and +15%. for the test banks). The sum of the individual control

I I

rod bank worths was measured to be within 3.8% 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 worth of the reference bank

~ (Control Bank B) are shown in Figures 4.1 and 4.2, respectively. The design

BORON ENDPOINT AND WORTH MEASUREMENTS

Boron Endpoint

With the reactor critical at hot zero power, reactor coolant system

boron concentrations were measured at selected rod bank configurations to

enable a direct comparison of measured boron endpoints with design predictions.

For each measurement, the RCS conditions were stabilized with the control bank

at or very near a selected endpoint position. The critical boron concentra-

tion was then measured. If necessary, an adjustment to the measured critical

boron concentration value was made to account for off-nominal core conditions,

i.e., for rod position and moderator temperature.

The results of these measurements are given in Table 5.1. As shown

in this table and in the Startup Physics Test Results and Evaluation Sheets

given in the Appendix, all measured critical boron endpoint values were within

their respective design tolerances. All measured values met the accident

analysis acceptance criterion. In summary, all results were satisfactory.

Boron Worth Coefficient

The measured boron endpoint values provide stable statepoint data

from which the boron worth coefficient was determined. A plot of the boron

concentration as a function of integrated reactivity can be constructed by

relating each boron endpoint concentration to the integrated rod worth present

in the core at the time of the endpoint measurement. The value of the

boron worth coefficient, over the range of boron endpoint concentrations, is

obtained directly from this plot.

The boron worth plot is shown in Figure 5.1. As indicated in

this figure and in the Appendix, the boron worth coefficient of reactivity

was measured to be -9.11 pcm/ppm. The measured boron worth coefficient is

within 5.9% of the predicted value of -8.60 pcm/ppm and is well within the

20

I ~ design tolerance of +10%. The measurement result also met the accident analysis

acceptance criterion. In summary, this result was satisfactory.

TEMPERATURE COEFFICIENT MEASUREMENTS

The isothermal temperature coefficient measurements were accomplished

by controlling the RCS heat gains/losses with the steam dump valves to the

condenser, establishing a constant and uniform heatup/cooldown rate, and then

monitoring the resulting reactivity changes on the reactivity computer. These

measurements were performed at very low power levels in order to minimize the

effects of non-uniform nuclear heating, thus, the moderator and fuel were

approximately at the same temperature (between 543-549 °F) during these measure-

ments. To eliminate the boron reactivity effect of outflow from the pressurizer,

the pressurizer level was maintained constant or slightly increasing during these

measurements.

Isothermal temperature coefficient measurements were performed at

various control rod configurations. For each rod configuration, reactivity

measurem.ents were taken during both RCS heatup and cooldown ramps during which

the RCS temperature varied approximately 6°F. Reactivity was determined using

the reactivity computer and was plotted against the RCS temperature on an x-y

recorder. The temperature coefficient was then determined from the slope qf the

plotted lines. The x-y recorder plots of reactivity change vs. RCS temperature

for each measurement are shown in Figures 6.1 and 6.2.

The predicted and measured isothermal temperature coefficient values

are compared in Table 6.1. As can be seen from this summary and from the

Startup Physics Test Results and Evaluation Sheets given in the Appendix, all

measured isothermal temperature coefficient values were within the design tolerance

of +3 pcm/°F and met the accident analysis acceptance criterion. In summary,

all measured results were satisfactory.

POWER DISTRIBUTION MEASUREMENTS

The core power distributions were measured using the incore movable

detector flux mapping system. This system consists of five fission detectors

which traverse fuel assembly instrumentation thimbles in 50 core locations

(see Figure 1.2). For each traverse, the detector output is continuously

monitored on a strip chart recorder. The output is also scanned for 61 discrete

axial points by the PRODAC P-250 process computer. Full core, three-dimensional

power distributions are then determined by analyzing this data using the Westing-

7 house computer program, INCORE. INCORE couples the measured flux map data

with predetermined analytic power-to-flux ratios in order to determine the power

distribution for the whole core.

A list of all the flux maps taken during the test program together

with a list of the measured values of the important power distribution parame-

ters is given in Table 7.1. The measured power distribution parameter values

are compared with their Technical Specifications limits in Table 7.2. Flux

Maps 1 and 2 were taken at zero power. These flux maps serve as base case

design checks. Figures 7.1 and 7.2 show the resulting radial power distributions

associated with these flux maps. The results of Flux Map 1 indicated a quadrant

power tilt ratio of slightly greater than 2%. However, during this map, the

flux level was low and there was a significant amount of flux drift. It is

believed that this contributed to the high tilt indication. Subsequent flux

map results confirmed that the quadrant power tilt ratio was less than 2%.

Flux Maps 4 through 13 were taken over a wide range of power levels and control

rod configurations. These flux maps were taken to check the at-power design

predictions and to measure core power distributions at various operating

conditions. These maps also provide incore/excore calibration data for the

28


nuclear instrumentation system. The radial power distributions for these maps

are given in Figures 7.3 through 7.10. These figures show that the measured

relative assembly power values are generally within 6% of the predicted values.

In conclusion, all power distribution measurement results were

considered to be acceptalbe with respect to the design tolerances, the accident

analysis acceptance criteria and the Technical Specification limits. It is

therefore anticipated that the core will continue to operate safely throughout

Cycle 5.
