5.0 STATION RADIOACTIVE EFFLUENT RELEASES AND SOLID RADIOACTIVE WASTE Date on radioactive effluents for the first six (6) months of 1975 are herewith reported in the form given in Appendix A of U.S.A.E.C. Safety Guide 21, dated December 29, 1971. Liquid concentrations were measured at their source prior to discharge to determine total activities released. Percent of technical specification limit for activity relea*sed is based on the limits specified in 10CFR20, Appendix B, for unrestricted areas and takes into.account the nuclides present, excluding tritium, and are calculated using data averaged over the actual time of discharge only and hence do not take credit for dilution water flow available at those times when releases were not being made. Halogen and particulate concentrations were measured by con-tinuous samples of all discharges near their points of release. Gas-eous concentrations were measured at the source prior to discharge to determine total activities released. Percent of applicable limit for airborne releases are based on the limits specified in 10CFR20, Appendix B. 5.0-1

10.3 CHANGES IN *FACILITY DESIGN The following changes were implemented during this reporting period: Design Change Unit

1. DC 73 Replace Valve Trim and Eliminate Snubbers 1 Description - This change modified the valve trim on valves PCV-CN-101 (201) in order to prevent damage to the condensate pump seal water line pressure regulators when starting up the condensate system.

Summary of Safety Evaluation

a. The probability of occurrence or the consequences of an accident or malfunction of equipment important to safety previously evaluated in the Safety Analysis Report is not increased. This equipment is not speci-fically addressed in the Safety Analysis Report.
b. The possibility for an accident or malfunction of a different type than any evaluated previously in the Safety Analysis Report is not created. This modifica-tion did not affect the safety of the unit.
c. The. margin of safety as defined in the basis for any t.echnical specification is not reduced. This valve is not the basis of any Technical Specification.

Conclusion - This.design change does not constitute an un-reviewed safety question or change the basis of any Technical Specification. 10.3-1

Design Change Unit

2. DC 73 Auxiliary Boiler Trouble Annunciator 1 Interlock Description - This change is part of a continuing effort to disable alarming annunciators when they are not needed Annunciator "Auxiliary Boiler A (B) Trouble" was inter-locked with the Program Control Switch so that the alarm does not occur when the boiler is shutdown.

Summary of Safety Evaluation

a. The probability of occurrence or the consequences of an accident or malfunction of equipment impor-tant to safety previously evaluated in the Safety Analysis Report is not increased. The Auxiliary Boilers are not safety related.
b. The possibility for an accident or malfunction of a different type than any evaluated previously in the Safety Analysis Report is not created. The operation of the auxiliary steam system is not affected.
c. The margin of safety as defined in the basis for any technical specification is not reduced. The auxiliary boilers are not the basis for any Techn-ical Specification.

Conclusion - This design change does not constitute an unreviewed safety question or change the basis of any Technical Specification. 10.3-2

Design Change Unit

3. DC 73-127 - Containment Escape Hatch 1 Description - The existing 18" diameter manway locking device was modified to prevent inadvertent opening. A locking pin and plate assembly, a pressure equalizing assembly and an instruction plate were installed.

Summary of Safety Evaluation

a. The probability of occurrence or the consequences of an accident or malfunction of equipment impor-tant to safety previously evaluated in the Safety Analysis Report is not increased. The manway lock-ing device is not evaluated in the Safety Analysis Report.

b, The possibility of an accident or malfunction of a different type than any evaluated previously in the Safety Analysis Report is not created. The manway operation was not affected. The locking device was improved without disturbing manway integrity.

c. The margin of safety as defined in the basis for any technical specification is not reduced. The manway locking device is not the basis for any Technical Specification. Additionally, the man-way leakage was not affected.

Conclusion - This design change does not constitute an unreviewed safety question or change the basis of any e Technical Specification.

10. 3-3

Design Change Unit

4. DC-74 Containment Instrument Air - Redundant 1 Piping Description - The modification consists of installing four (4) check valves - two (2) in the discharge lines of the compressors and two (2) in the inlet lines of the receivers. In the event that one compressor de-velops a leak to atmosphere, the discharge line check valves prevent the other compressor from discharging through this leak instead of into the receivers. The check valves in the receiver inlet lines, in conjunc-tion with the discharge line check valves, protect system pressure in the event of a receiver leak to atmosphere.

Summary of Safety Evaluation

a. The probability of occurrenc_e or the consquences of an accident or malfunction of equipment impor-tant to safety previously evaluated in the Safety Analysis Report is not increased. The modification improved performance of the system.
b. The possibility for an accident or malfunction of a different type than any evaluated previo~sly in the Safety Analysis Report is not created. The design of the system was improved by this change.

Normal operation of this system is unaffected by this modification.

c. The margin of safety as defined in the basis for any technical specification is not reduced. The
10. 3-4

containment instrument air compressors are not contained in the basis of any Technical Speci-fication. Conclusion - This design change does not constitute an unreviewed safety question or change the basis of any Technical Specification. 10.3.-5

Design Change Unit

5. DC-74 Add Bypass Line Around Strainers 1 (2)- 2 SW-S-6.

Section I INTRODUCTION AND

SUMMARY

On September 26, 1975 after almost eight months of commercial operation, Surry 1 completed CycJe 2. Since initial criticality of Cycle 2 on January 30,1975 the reactor core has produced over 40 x 106 MBTU(6,915 Megawatt days per metric ton of contained uranium) which has resulted in the generation of some 4.3 x 10 8 kwhr of electrical energy. The purpose of this report is to present an analysis of the core performance for routine operation during Cycle 2. Non-routine operation was covered in the Surry 1 - Cycle 2 startup physics test report(l) and, therefore, will not be included here. Routine core follow involves the analysis of four principal performance indicators. These are burnup distribution, reactivity depletion, power distribution, and primary coolant activity. The core burnup distribution is followed to verify both burnup symmetry and proper batch burnup sharing, thereby ensuring that the fuel held over for the riext cycle will be compatible with the new fuel inserted. Reactivity depletion is monitored to: detect the existence of any abnormal reactivity behavior, determine if the core is depleting as designed, and indicate at what burnup level refueling will be required. Core power distribution follow includes the monitoring of nuclear hot channel factors to verify that they are within the Technical Specifications limits thereby ensuring that adequate margins to linear power density and critical heat flux thermal limits are maintained. Lastly, as part of normal core follow, the primary coolant activity is monitored to assess the integrity of the fuel. In addition to the above, the effects of fuel densification were monitored. Although not normally part of routine core follow, this phenonmenon is treated here because of its impact on core performance. (l)Lippard,_ D.W., and Keck, S.P., Surry Unit 1 Startup Physics Test Report - Cycle 2, VEP~FRD-11, Richmond, Virginia, July, 1975. 1

Each of the four performance indicators, as well as the status of observed fuel densification effects, is discussed in detail for the Surry 1 2 Cycle 2 core in the body of this report. ( ) The results are summarized below:

1. Burnup Follow - The burnup tilt (deviation from quadrant symmetry) on the core is less than+ 0.6% with the burnup accumulation in each batch deviating from design prediction by less than 3%.
2. Reactivity Depletion Follow - The critical boron concentration, used to monitor reactivity depletion, has consistently been within+/-_ 0.5% IK/K of the design,prediction which is well within the+/-_ 1% IK../K margin allowed by the Technical Specifications.
3. Power Distribution Follow - Incore flux maps taken each month indicate that the radial power distributions were generally within+ 5% of the design predictions with all hot channel factors meeting the Technical Specifica-tions limits.
4. Primary Coolant Activity Follow - The iodine-131 activity level in the primary coolant at the end of Cycle 2 is on the order of 10-l µ Ci/ml which indicates there are approximately 15 to 20 fuel defects in the core, This gives the unit a fuel integrity factor which is >99.95%.
5. Fuel Densification Status - There are eight confirmed and eight suspected assembly locations with power spikes due to pellet gap formation.

However, all power spikes are small, that is, less than 2% in magnitude, (2) See Appendix A for definition of terms used in this report. 2

Section 2 CORE PERFORMANCE ANALYSIS 2.1 Burnup Follow The burnup history for the Surry Unit 1. Cycle 2 core is graphically depicted in Figure 2.1.1. A chronology of the associated operating power level is given in Figure 2.1.2. Cycle 2 burnup for the Surry 1 core was 6915 MWD/MTU. As shown in Figure 2.1.3, the average Surry 1 load factor for Cycle 2 was 85% when referenced to rated thermal power (2441 mw(t)). The burnup sharing on a batch basis is monitored to verify that the core is operating as designed and to enable accurate end-of-cycle batch burnup predictions to be made for use in reload fuel design studies. As seen in Figures 2.1.4 and 2.1.5, the batch burnup sharing for Surry 1 followed design predictions very closely with each batch deviating approximately 3% from design; this is considered excellent agreement. Radial burnup maps distribute the gross core burnup among the various fuel assemblies and thereby allow a more detailed burnup distribution analysis. The TOTE computer code (see Appendix B) was used to calculate these assemblywise burnups. Figure 2.1.6 is a radial burnup map in which the assemblywise burnup accumulation of the core as of September 26, 1975 (end of Cycle 2) is given. For comparison purposes, the predicted values are also given. As can be seen from this figure, the accumulated fuel assembly burnups are generally within+ 4% of the predicted values. In addition, deviation from quadrant symmetry in the core, as indicated by the burnup tilt factors, is less than+/- 0.6%. Therefore, synunetric burnup in conjunction with good agreement between actual and predicted assemblywise burnups and batch burnup sharing indicate that the Cycle 2 core depleted as designed. 2.2 Reactivity Depletion Follow The primary coolant critical boron concentration is monitored for the 3

purposes of following core reactivity and flagging any anomalous reactivity behavior. The FOLLOW computer code (see Appendix C) was used to normalize "actual" critical boron concentration to design conditions taking into considera-tion off-normal rod positions, xenon and samarium concentrations, moderator* temperatures, and power levels. The normalized critical boron concentration versus burnup curve for the Surry 1 Cycle 2 core is shown in Figure 2.2.1. It can be seen that the measured data compare within +/-40 ppm of the design prediction. This corresponds to within +/- 0. 44 I::, K/K, which is well within the +/- 1% /J. K/K criteria for reactivity anomalies set forth in Section 4.10 of the Technical Specifications. In conclusion, the trend indicated by the critical boron concentration verifies that the Cycle 2 core depleted as expected without any reactivity anomalies. 2.3 Power Distribution Follow Analysis of core power distribution data on a routine basis is necessary to verify that the hot channel factors are within the Technical Specifications limits and to ensure that the reactor is operating without any abnormal conditions which could cause an "uneven" burnup distribution. Three-dimensional core power distributions were determined from movable detector flux map measurements using the INCORE computer program (see Appendix D). A summary of all flux maps taken since completion of startup physics testing for Surry 1 Cycle 2 is given in Table 2.3.1. Power distribution maps were generally taken at monthly intervals with additional maps taken as needed. Radial (X-Y) core power distributions for a representative series of incore flux maps are given in Figures 2.3.1 through 2.3.3. Figure 2.3.1 shows a power distribution map that was taken early in cycle life. Figure 2.3.2 shows a power distribution map that was taken near mid-cycle burnup. Figure 2.3.3 shows a , map that was taken late in Cycle 2 life. All of the radial power distributions sp.own were taken under equilibrium operating conditions with the Unit operating 4

at approximately 90% to 100% power. In each case, the measured fuel assembly powers are generally within 5% of the predicted values, which is considered good agree_ment. In addition, as indicated by the INCORE tilt factors, the power

.distributions are essentially symmetric for all cases.

Another important aspect of core power distribution follow is the monitoring of nuclear hot channel factors. Verification that these factors are within Technical Specification limits ensures that linear power density and critical heat flux limits will not be violated, thereby providing adequate thermal margins and maintaining fuel cladding integrity. The Technical Specification Limit on the axially dependent heat flux hot channel factor, F~(Z), changed once during the operation of Cycle 2. F~(Z) T is defined as FQ X K(Z), where K(Z) is given in Figure 2.3.4. Prior to the accep-tance of our second revised ECCS analysis on June 16, 1975, the limit on F~(Z) was 2.32 X K(Z). As seen from Figure 2.3.8, the current limit on F~(Z) is 2.10 X K(Z). Throughout the cycle, the Surry 1 core maintained an F~(Z) (with and without T densification penalties) of at least 6% less than the applicable FQ(Z) Technical Specification limit. The axially dependent heat flux hot channel factors for a representative series of maps are given in Figures 2.3.5 through 2.3.7. T Peak linear power density, which is determined directly from FQ' is given in Figure 2.3.9. This is the limiting parameter from a loss-of-coolant accident-ECCS standpoint since it directly relates to the stored thermal energy ' in the core. As shown in Figure 2.3.9 the Surry 1 Cycle 2 core has maintained a peak linear power density of at least 13% below the allowable limit. A radial hot channel factor routinely followed is ~NH, the enthalpy* rise hot channel factor. The Technical Specifications limit for this parameter is set such that the critical heat flux (DNB) limit will not be violated. Figure 2.3.10 shows that at least a 4% margin to this limit has been maintained. 5

e Another radial hot channel factor routinely monitored is F xy

                                                                               , the horizontal plane peaking factor. This peaking factor is a ratio of the peak to average power in a given horizontal plane. It is related to, but is not identical to, FfiNH which is the ratio of the integral of power along the rod with the highest integrated power to that of the average rod.      As shown in Figure 2.3.11, the measured Fxy peaking factors, evaluated at core mid-plane, are as much as 1.5%

higher than the nominal design prediction. However, this is well w:i,.thin the design uncertainty of 8%. (3) The technical specifications require that target delta flux values be determined monthly. Operational delta flux limits are then established about this target value; and by maintaining a relatively constant delta flux, adverse axial power shapes are avoided. A plot of delta flux versus burnup and several corresponding core average axial power distributions for a representative series of maps are given in Figures 2.3.12 through 2.3.15. As can be seen from these figures, d*elta flux values and the corresponding axial power distributions have remained relatively constant throughout Cycle 2. Consequently as seen in Figure 2. 3.16, the core average axial peaking factor- (Fz) has also remained relatively constant at approximately 1.15 throughout the cycle. This is consistent with design predictions which indicate that F would remain between 1.1 and 1.2 2 throughout Cycle 2. In conclusion, the Surry 1 Cycle 2 core performed very satisfactorily, with power distribution analyses verifying that design predictions were accurate and that the hot channel factors met their Technical Specifications limits.

~ 2.4 Primary Coolant Activity Follow Activity levels of iodine 131 and 133 are important in core performance follow analyses because they are used as indicators of defective fuel. These two isotopes leak into the primary *coolant system through a breach in the fuel cladding. 1-131 activity is directly correlatable to the number of cladding defects; the ratio of 1-131 to 1-133 is used to determine the type of fuel failure which has occurred in the reactor core. Use of the ratio for this determination is feasible because 1-133 has a short half-life (approximately 24 hours) compared to that of 1-131 (approximately eight days) so that for pinhole defects where the diffusion time through the defect is on the order of days, the 1-133 decays out leaving 1-131 dominant in activity thereby causing the ratio to be 0.5 or more. In the case of large leaks, uranium particles in the coolant, and/or "tramp"( 4 ) uranium, where there is no diffusion time, the 1-131/1-133 ratio will generally be less than 0.1. Figure 2.4.1 shows the 1-131 activity history for the Surry 1 Cycle 2 core with the FSAR value for one fuel defect( 5 ) (which is equivalent to one defective rod) and five defects (an equivalent to five defective rods) delineated for comparison purposes. The data shows considerable scatter but the trend indicates that on the order of ten to twenty defective fuel rods exist in the core. As shown in Figure 2.4.2, the 1-131/1-133 ratio data points fall well above 0.5, thus indicating that the defective rods most likely have pinhold defects. Small quantities of fuel defects are common in operating reactors, and in fact, the reactor systems are normally designed to operate with up to approximately 1% failed fuel present. With ten to twenty defects present, Surry 1 (4) "Tramp" uranium consists of small particles of uranium which adhere to the outside surface of the fuel during the manufacturing process. (5) This is derived from FSAR Table 9.1-5 where cladding defects in 1% of the fuel rods gives an 1-131 primary coolant activity concentration of 1.68 µ.Ci/cc

       @ 560°F. Samples are analyzed at room temperature; hence, this value is 2.35 HCi/cc when a density correction is made.

had a Cycle 2 core fuel integrity factor of> 99. 95% which is better than most operating reactors and is considered acceptable. 2.5 Fuel Densification Status Table 2.5.1 gives the assembly locations, along with assembly related data in which densification-induced power spikes have been observed. The total number of suspected and confirmed( 6 ) power spikes has increased since the last report; however, the magnitudes of all power spikes are still very small, the largest being 1.3% for Assembly E-11. It has been noticed that the power spike locations do not generally change from one map to the next although in a few instances confirmed power spikes have disappeared, apparently due to the settling of the fuel column. Figures 1 th~ough 16 of Appendix E are the latest Surry 1 Cycle 2 strip-chart traces for all confirmed and suspected fuel assemblies with densifi-cation indµced fuel pellet gaps. Note that in nearly all cases the power spike is located above the midplane and usually is in the top one-third of the fuel, which is where gap formation of notable size is most likely to occur. Unfortunately, the width of the power spike is not a direct indication of gap width since the detector is. running down the center of the assembly and "sees" a composite effect of many fuel pins. In conclusion, while the number of the densification induced power spikes has increased since the last report, the magnitude of the power spikes has remained relatively low. (6) A confirmed power spike is one which has been observed in two *or more recent maps. A suspected power spike is one which has been observed only in the most recent map. 8

Section 3 CONCLUSIONS The Surry 1 core has completed Cycle 2. Throughout this cycle, all core performance indicators compared closely to design predictions and all Technical Specifications limits were met by significant margins. No abnormalities in reactivity, power distribution, or burnup accumulation were detected. In addition, the excellent mechanical integrity of the core has not changed perceptibly throughout Cycle 2, as indicated by the radioiodine analysis. Lastly, fuel densification effects in terms of detected fuel pellet gap formation has been shown to be less than originally anticipated. 36

Appendix A DEFINITION OF TERMS ACTIVITY - Number of nuclear disintegrations per unit time taking place in a radioact~ve nuclide. Usually expressed in terms of

              µCi (3.7 x 10 disintegrations per second).

AXIALLY DEPENDENT HEAT FLUX HOT CHANNEL FACTOR -FQ(Z)- The maximum local heat flux on the surface of a fuel rod at a core elevation Z divided by the average fuel rod heat flux. AXIAL OFFSET - The percent difference between the fraction of total core power produced in the upper half of the core and that produced in the lower half of the core. BATCH - A group of assemblies which are inserted into the reactor at the same time. All of the assemblies in a batch may or may not have the same nuclear characteristics or be discharged at the same time. (See REGION) BORON (Soluble) - A strong neutron absorber which is dissolved in the reactor coolant and used for reactivity control. The boron concentration in the coolant is expressed in terms of parts per million water (ppm). BURNUP - The quantity of energy produced per unit weight of fuel. It is a measure of fuel consumption and typically has units of

  • megawatt-days per metric ton of initially contained uranium (MWD/MTU).

CRITICAL - Condition in which the neutron chain reaction in a reactor is just self-sustaining. CRITICAL BORON CONCENTRATION - The concentration of soluble boron in the coolant at which the reactor is just critical. CRITICAL HEAT FLUX (DNB) - The point of transition between nucleate boil-ing and film boiling at the coolant-clad interface. Beyond this critical heat flux point, a vapor blanket forms on the cladding surface and acts as an insulator, thereby resulting in abnormally high clad temperatures. DENSIFICATION - A recently discovered phenomenon in which the UCQ fuel pellets shrink both radially and axially as a result of neutron irradiation. DENSIFICATION-INDUCED GAPS - When a colunm of UOz pellets in a fuel rod shrinks due to densification, gaps may be formed in the pellet column. FISSION PRODUCTS - Residual nuclei which are generated during the fission process and which retain nearly all of the energy formed in the process.

FLUX (NEUTRON) - A measure of the intensity of neutrons, i.e., the number of neutrons passing through one square centimeter in one second. FLUX MAP - A three-dimensional representation of the flux distribution throughout the core. It is obtained from measurements made with the movable detector system. (See MOVABLE DETECTOR) HALF-LIFE - Period of time in which a radioactive element decays to half its original concentration. IODINE-131; IODINE-133 - Fission products which, because of their radio-active and chemical properties, can be used to determine fuel clad defects. LINEAR POWER DENSITY - Power generated per unit length of fuel rod. This parameter is a measure of the central temperature of the fuel rod and stored heat. Usually expressed in units of Kw/ft. LOAD FACTOR - The ratio of the actual reactor energy generated over a period of time to the potential energy which could have been generated by the reactor over that same period of time. MOVABLE DET°ECTOR - A traversing incore fission chamber which generates a voltage signal proportional to the flux level the chamber "sees". Five such detectors are moved at one time through the core to monitor the flux distribution. A total of *so locations are traversed to generate a complete flux map of the core (See FLUX MAP) NODE - The core is divided into 60 equally spaced axial segments by the movable detector monitoring system. Nodal representation is then used by the INCORE program in deriving the power distributions. POWER DENSITY - Power generated per unit volume in* the core. Usually expressed in units of Kw/Liter. POWER SPIKE - A local increase in power due to densification-induced gaps in the pellet stack. RADIAL POWER MAP - An X-Y distribution of power on an assembly basis, normalized to the average assembly power. J, REACTIVITY - In a nuclear reactor, a measure of the departure from a just critical condition. Usually expressed in units of pcm (10-5 ~K/K), it is normal to refer to a pcm quantity of reactivity associated with some component of the reactor ...,~ since removing that component will change the reactivity of the reactor by that amount.

RE;GION - A group of assemblies which have essentially the same nuclear design characteristics and are inserted into the reactor at the same time. (See BATCH) TECHNICAL SPECIFICATIONS - The document setting forth mandatory operational and surveillance requirements for a nuclear facility. It is issued by the NRC as part of the operating license. TILT - A deviation fr~m perfect symmetry. Usually used with respect to radial burnup or power distributions and relates each quadrant to the average of all four quadrants. XENON - A gaseous fission product which has a very strong neutron absorption capability. Unless controlled, the xenon concentration can shift up and down the axial axis of the core, thereby causing axial power transients. 8 K/K - Mathematical expression for reactivity, where "K" is the ratio of the number of neutrons present in a reactor in any one neutron generation to that in the immediately preceding generation. (See REACTIVITY)

Appendix B TOTE PROGRAM DESCRIPTION e TOTE is an isotopic and burnup follow computer program written by the Westinghouse Electric Corporation to accurately keep track of the iso-topic content of the fuel and the accumulated fuel burnup. It is presently operational on the Virginia Electric and Power Company's IBM-370 computer system. In the analysis_of in-core flux maps the INCORE code punches out burnup rate information for every fuel region. These regions normally include each fuel assembly (and fueled follower) and about one hundred indi-vidual fuel rods of interest. The burnup rate is given as the megawatt-hours generated in a given fuel region per 1000 megawatt-hours generated by the core. The total for each fuel region is given as well as the value for each of four axial segments of approximately equal length. In addition, the core average axial power distribution is punched out. The TOTE user inputs: (a) the core energy (megawatt-hours) associated with each of the above burnup rate decks; (b) cards describing each fuel region (including MTU, corresponding INCORE source number, previous burnup, isotopic depletion type, etc.); (c) tables of the change in isotopics (U-235, U, Pu, etc., up to ten constituents) with burnup; and, (d) the burnup rate decks from INCORE. Printed output includes a listing of the input; core, cycle and fuel region burnup; fuel assembly isotopics; the energy weighted core average axial power distribution; and the initial and current uranium concentrations for each fuel batch and the core. Isotopic concentrations of the fuel assemblies are obtained by a quadratic interpolation of the data which is contained as part of the input isotopic table sets. Punched output consists of Item (b) above for subsequent TOTE runs.

Appendix c. FOLLOW PROGRAM DESCRIPTION FOLLOW is a data analysis computer program written by Westinghouse Electric Corporation to process reactor operation data and calculate critical boron concentrations for the reactor operating under nominal conditions. It is presently operational on the Virginia Electric and Power Company's IBM-370 computer system. The FOLLOW Code describes the nearly linear relationship between available core reactivity and cycle burnup. It is most convenient to use boron as a measure of core reactivity with off nominal* corrections being made for power level, xenon and samarium concentrations, coolant temperature, and control rod position in terms of their boron worth. These corrections are made as can be seen from this equation: off nominal corrected or measured reactivity correction nominal boron concentration boron concentration t due to rod group 1 position off nominal off nominal

      +   reactivity correction      +       reactivity correction due to rod group                     due to moderator 2 position                           temperature off nominal                            off nominal    ]
      +   reactivity correction      +       reactivity correction due to power                         due to xenon and samarium behavior Options are chosen so as to satisfy the above equation in ways appropriate to the condition of the reactor and its method of operation.

The boric acid concentration in the primary loops of operating PWR's is typically measured *one to three times per day. After proper normalization, this data is plotted against cycle burnup and forms the '~oron depletion curve."

  • Nominal conditions generally mean hot full power equilibritllll conditions with control rods out of the core.
  • Since this curve is well behaved and nearly linear from beginning to end of the cycle, it can provide the following information:
1) Detection of abnormal (unexpected) behavior in core reactivity. The power station Technical Specifications require boron follow for this purpose.
2) Extrapolation to end-of-cycle life for scheduling refueling, or determina-tion of end-of-life for contractual purposes.
3) Rate of loss of reactivity with burnup for confirmation of design para-meters.
4) Indication of the need for updating reactivity coefficients needed for plant operation.
5) Best estimate of beginning of cycle, hot-full-power criticality under equilibrium conditions *
 *Appendix D INCORE PROGRAM DESCRIPTION INCORE is a data analysis computer program written by the Westinghouse Electric Corporation to process information obtained by in-core instrumentation.

It is presently operational on the Virginia Electric and Power Company's IBM-370 computer system. In the reduction of in-core flux and temperature measurements the INCORE code performs the following:

1. Reads input consisting of (a) a description of the amount and type of data to be read in (such as nu~ber of flux traces and thermocouple readings, etc.); (b) a description of the reactor during the measure-ments (such as power level, inlet and outlet temperature,.etc.);

(c) the actual data and information relevant to it (such as the flux thimbles that were used, neutron cross sections of the movable detectors, etc.); (d) analytical information (such as calculated thimble fluxes,calculated fuel assembly power, etc.); and (e) specification of options as to what thimbles will be employed in local power predictions, what calculations are to be done, etc.

2. Corrects raw pointwise flux measurements for leakage current, changes in power level between measurements, relative detector sensitivities, etc. j to determine the pointwise reaction rate in the flux thimbles.
3. Compares the measured reaction rates with their design values and rejects data if they differ from expected values by more than an input rejection criteria. An error analysis is performed for subsequent determination of the uncertainty to attach to calculated peaking factors.

- .~*

4. Computes the relative power produced by each fuel assembly, and in e each fuel rod chosen for attention. Local relative power is computed as:

j r t Local Power* eaction Rate i] Reaction Rate in Flux Thimble X Flux Thimble*

  • Measured Analytical Average of Numerator for All Fuel in Core Local absolute power or heat flux is then computed by multiplying the above quantity by the average specific power or heat flux in the core determined from the measured total core power at the time the data were taken. A weighted average of data from nearby thimbles can be used in determining local relative power.
5. Calculates the relative quadrant powers and the core average axial power distribution in the core. The expected and measured power peaking factors are compared for each power generating region.
6. Outputs the twenty highest values of F!H and~ in descending order with an identifying number so that hot spot locations in the core can be determined.
7. Calculates the local heat flux hot channel factor as a function of core height and compares the values to the Technical Specification limit.
8. Calculates the rate at which burnup is being accumulated for four r

J axial regions for each fueled area.

9. Corrects thermocouple data for calibration, and converts them to local enthalpy. Relative local enthalpy rise is then.calculated e using the vessel inlet and outlet temperatures and the core bypass

flow. The local enthalpy rise measured by thermoco~ples is compared with that predicted from flux measurements using relative local flow rates.

10. Calculates the margin to departure from nucleate boiling (DNB) using*

the W-3 correlation for selected channels.

11. Lists the plant input data, the analytical parameters used, and the major calculated values.

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 1 Cycle 3 reload 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 data, 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 analysis presented includes a brief summary of each test, a comparison of the test results with design predictions, and an evaluation of the results. V

Section 1 INTRODUCTION AND

SUMMARY

On September 26, 1975, Unit No. 1 of the Surry Power Station was shut down for its second refueling. During this refueling, 81 of the 157 fuel assemblies in the core were replaced with 65 once-burned assemblies from Cycle 1 and 16 fresh fuel assemblies. The third cycle core consists of six regions of fuel: two once-burned regions from Cycle 1 (Regions 1 and 3), three once-burned regions that are carried over from Cycle 2 (Regions 4A, 4B, and 4C), and one fresh region (Region 5). The design parameters for each region and the actual core loading pattern are shown in Figure 1-1. Note that as part of Region 4A there are two 17xl7 rod array assemblies. These have been inserted for demonstration purposes. On December 6, 1975 at 0258, initial criticality was achieved on the third cycle core. Following criticality, startup physics tests were performed as outlined in Table 1-1. A summary of the results of these tests follows:

1. Total control rod bank worth for rod banks C and D was measured to be within 2% of the design predictions performed by Westinghouse. This is well within the 10%

accuracy range normally associated with such design predictions.

2. Isothermal temperature coefficients over the range of normal operating control rod bank insertion were all within 2.5 PCM/°F of the design prediction values. (NOTE: PCM=

10-5 ~p)

3. The boron worth coefficient was measured to be within 8% of the design prediction value.

4. Critical boron concentrations for the basic control bank configurations indicated a reactivity difference of approximately 0.25% ~K/K (maximum) from prediction which is well within the error band normally associated with this design prediction comparison.
5. Core power distributions for various HZP and at-power conditions were found to be generally within 3 to 6% of the predicted power distributions and, in all cases, were considered satisfactory. Furthermore, all hot channel factors were found to be within Technical Specifications limits.

Section 2 CONTROL ROD BANK WORTH MEASUREMENT Differential and integral control bank worths were obtained by maintaining the reactor approximately critical through boron/RCCA exchanges. Following the establishment of a constant boron dilution/boration rate, the controlling RCCA bank was periodically inserted/withdrawn in order to provide reactivity compensation for the changing RCS boron concentration. The reactivity changes resulting from the control bank movements were recorded on a continuous basis by the reactivity computer (see Appendix A). The differential reactivity worth was defined as the ratio of the change in reactivity to the corresponding change in bank position about an average bank poS'ition, and the integral worth was obtained by summing the individual reactivity changes between measurement endpoints. A summary of the results for these tests is given in Table 2-1. Table 2-1 includes a comparison of measured data to Vepco as well as to the Westinghouse design predictions. As shown by this table, the measured values of the rod worth were within 8.4% of the design prediction values. A 10% uncertainty is normally associated with rod worth predictions. Integral and differential reactivity worths for individual rod banks are shown in Figures 2-1 through Figure 2-4. The measured data is plotted with. the Westinghouse design predictions in order to illustrate the agreement between them. The rod worth measurements are quite exact in defining the shapes of the individual differential rod worth curves, as illustrated by the distinct depressions occurring at the assembly grid locations. 2.1

Integral and differential worth for control banks C and D operating e in the overlap mode are shown in Figures 2-5 and 2-6, respectively. Again, the measured data is plotted with the Westinghouse design predictions in order to illustrate the agreement between them. In conclusion, rod worth measurements compare favorably with design predictions and are within the 10% accuracy range normally associated with such measurements. 2.2

Section 3 -* TEMPERATURE COEFFICIENT MEASUREMENTS As part of the low power physics testing program, the reactivity effect of the temperature of the reactor coolant was determined by measuring the isothermal temperature coefficient of the reactor. This was accomplished by controlling the RCS heat losses/gains through the use of the steam dump valves to the condenser in order to establish a uniform cooldown/heatup rate and then monitoring the resulting reactivity changes on the reactivity com-puter. These measurements were performed at very low power levels in order to minimize the effects of nuclear heating (Doppler feedback). The moderator (coolant) and fuel were approximately at the same temperature (-547°F) during this measurement. Finally, to eliminate the boron reactivity effect of out-flow from the pressurizer, the pressurizer level was maintained constant or slightly increasing during the measurement. The isothermal moderator temperature coefficient measurements were performed at various control rod configurations. For each rod configuration, measurements were performed during an RCS cooldown and heatup ramp during which the RCS temperature varied between 3 and 4°F. Reactivity was determined using the reac,tivity computer and was plotted against RCS temperature on an X-Y recorder. The temperature coefficient was then determined from the slope of the plotted line. The predicted and measured isothermal temperature coefficients are summarized in Table 3-1. As can be seen from Table 3-1, all measured temper-ature coefficients were more positive than their respective predicted values 0 by a maximum difference of 2.47 PCM/ F. Typical data sets for each control rod configuration at which measurements were made are plotted in Figures 3-1 through 3-5. 3.1

As predicted, a positive tsothermal temperature coefficient, and, consequently, a positive moderator temperature coefficient* were measured with the r¢actor at hot zero power with all of the control rods withdrawn. Jhis was due to the high initial boron concentrations. However, because the Surry Power Station Technical Specifications (T.S. 3.1.E.1) currently do not allow operation of either unit with a positive moderator coefficient (except during physics testing), it was necessary to develop from the measured temperature coefficient values a rod withdrawal limit curve that would pre-clude the operation of Surry Unit 1 with a positive moderator coefficient. This operating limit curve, together with supporting calculations, are given in Appendix B.

Section 4 BORON WORTH AND ENDPOINT MEASUREMENTS

         .Reactor coolant system boron measurements were made during low.

power physics tests to determine boron reactivity worth and concentration endpoints at basic control rod configurations. BORON WORTH Concurrent with the control bank reactivity measurements, samples of RCS water were obtained for boron analysis. These samples were obtained with a high degree of frequency (15 minute intervals) during the dilution and boration phases of the measurement program in order to provide adequate statistics for the determination of the differential boron worth. Relevant data logged during this measurement were the control bank position (and hence integrated reactivity) as a function of time, and RCS boron concentration as a function of time. With these data, one can construct a plot of boron concentration as a function of integrated reactivity; the slope of which is the value of the differential boron worth. The result of these measurements is shown in Figure 4-1. As indi-cated in this figure, the boron worth coefficient of reactivity was measured to be 11.0 PCM/PPM. The measured boron coefficient is within 8% of the Westinghouse and Vepco design prediction value of 10.2 PCM/PPM, which is acceptable. BORON ENDPOINTS Critical boron concentration "endpoint" measurements were made 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, and the base just critical boron concentration 4.1

was determined. To this value a slight adjustment for rod position was made to obtain a critical boron endpoint at the exact desired control bank config-uration. The results of these measurements are given in Table 4-1. As shown in this table, the critical boron concentrations agree closely with the Westinghouse predicted values. The results indicate a reactivity difference of less than 0.25% 8K/K, which is well within the+/- 0.5% 8K/K error band normally associated with such analytical predictions. Vepco predicted values for critical boron concentrations are also included in Table 4-1, and as with the Westinghouse predictions, there is close agreement with the measured end-points. In all cases, the reactivity difference between Vepco predictions and measured endpoints is less than 0.15% 8K/K, which is well within the+/- 0.5% 8K/K error band normally associated with such analytical predictions. 4.2

Section 5 POWER DISTRIBUTION MEASUREMENTS The core power distributions for Surry 1 are measured through the use of the incore movable detector flux mapping system. This system consists of five fis$ion detectors which can traverse fuel assembly instrumentation thimbles in 50 core locations. (Should one detector fail, the remaining four are still capable of traversing all fifty thimble locations through the use of the emergency mode.) For each traverse, the detector output is continuously monitored on a strip chart recorder and, if desired, the detector output can also be scanned for 61 discrete axial points by the PRODAC process computer. Full core, three-dimensional power distributions are then determined using the Westinghouse computer program, INCORE. INCORE couples the experimental flux map measurements with predetermined analytic power-to-flux ratios to determine the power distribution for the whole core (see Appendix C). A list of all the flux maps taken during the test program, along with a summary of the important power distribution parameters for each map, are given in Table 5-1. Radial (X-Y) core power distributions for the flux maps that were taken to verify proper core loading and design predictions and to measure core power distributions at various operating conditions are given in Figures 5-la through 5-9b. (Figures with the subscript "a" are radial power distributions calculated using Westinghouse developed analytical power to flux ratios and compared to Westinghouse predicted radial power distribu-tions, while figures with the subscript "b" are radial power distributions calculated using Vepco developed analytical power to flux ratios and compared to Vepco predicted radial power distributions.) Flux maps 1 and 2 were taken at 3% and 25% power levels, respectively. These maps serve as base case design check maps taken to verify that the core 5.1

was loaded properly. Figures 5-la and band 5-2a and b show the resulting radial power distributions of these flux maps. As seen in Figures 5-la and 5-2a, the measured assembly powers are generally within 4% of the Westinghouse predicted values. This difference is typical of such maps and is considered acceptable. Comparisons with Vepco predictions are shown in Figures 5-lb and 5-2b. As seen in these figures, the measured distributions also compared favorably .with the design predictions. It is, therefore, concluded that the Surry 1, Cycle 3 core was loaded properly. Flux maps 3 through 9 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 typical operating conditions. These maps also provided incore/excore calibration data for the nuclear instrumentation system and base data for manual axial power distribution surveillance (T.S.3.12). The radial power distributions for these maps are given in Figures 5-3a through 5-9b. As seen in these figures, the measured assembly powers for all maps compared well, generally within 6%, with both the Vepco and Westinghouse design predictions. Therefore, it is concluded that the design predictions are adequate for typical operating conditions. Finally, the results of the flux maps that were taken during startup physics testing are compared to Power Distribution Limits as given in Section 3.12...:B of the Surry Technical Specifications. Table 5-2 summarizes this com-praison, and as shown by this table, the Technical Specification Limits were met in every case. In conclusion, all measurements were close to cl.esign predictions and within Technical Specifications limits; it is therefore anticipated that the core will continue to operate safely throughout Cycle 3; 5.2

Appendix A REACTIVITY COMPUTER Reactivity worth measurements were made using a reactivity computer, which is an a~alog computer specially developed to provide an on-line *solution to the point kinetics equations. The input signal to the reactivity computer is provided by the plant power range ion chambers. During zero-power measurements, one of the four available long ion chambers is taken out of normal service and its signal is used to drive the reactivity computer. Signals from the top and bottom sections of the detector are summed, and the resultant signal is converted to a voltage by a picoammeter for input to the reactivity computer. At zero power, the normal plant isolation amplifiers do not supply sufficient signal strength to be usable by the reactivity computer. Therefore, a plant channel must be taken out of service so that the current output can be converted to voltage and amplified for use by the reactivity computer. At power, the voltage output of the isolated amplifiers of both sections of the four plant channels are averaged and fed directly to the reactivity computer. The objective of this detector arrangement is to eliminate any axial effects which are often observed when a single short ion chamber is used to drive the reactivity computer. During power measurements, radial as well as axial effects are important; especially during single-rod reactivity measure-ments. Hence, the top and bottom sections of all four plant channels are used as input to the computer. This provides a signal that is radially, as well as axially averaged. A.l

Appendix B MODERATOR COEFFICIENT ROD WITHDRAWAL LIMITS Prior to startup of Surry Unit 1, Cycle 3, the occurrence of a positive moderator temperature coefficient of reactivity for the Surry 1, Cycle 3 reload core had been predicted at certain HZP conditions by the design calculations.* The startup physics testing program verified the exis-tence of this. positive moderator coefficient at HZP ARO and Bank D-in condi-J tions. Because the Surry Power Stations Technical Specifications (T.S.3.1.E.1) currently prohibit the operation of the plant with a positive moderator coefficient during normal operation, it was necessary to develop a set of operating restrictions in terms of rod withdrawal limits as a function of RCS boron concentration which would insure that Surry 1 would be operated with a negative moderator temperature coefficient. The rod withdrawal limit curves were developed by using the measured HZP temperature coefficient data obtained during the startup physics test program. A 0% power base limit curve was first developed using equation 1 with an additional 0.5 PCM/°F c-45 ppm) added to the measured data to insure conservatism in the calculations.

(Table 1 summarizes the data used to develop the HZP base limit curve.) Then, several at-power conditions were developed relative to the 0% power "base" limit curve. These additional power level curves (25%, 50%, 75%, and 100%) were obtained by applying the change in boron concentration due to negative reactivity effects (power defect) to the base 0% power level condition. T.hese boron changes were taken from the Westinghouse Nuclear Design Report (WCAP-8619) at the points where the moderator coefficients were 0 0.0 PCM/ F. Table 2 summarizes this information and also includes the rela-tive 0% power level points. The final moderator coefficient rod withdrawal limit curve is given in Figure 1.

Appendix C INCORE PROGRAM DESCRIPTION INCORE is a data analysis computer program written by the Westingho~se Electric Corporation to process information obtained by in-core instrumentation. It is presently operational on the Virginia Electric and Power Company's IBM-370 computer syste~. In the reduction of in-core flux and temperature measurements the INCORE code performs the following:

1. Reads input consisting of (a) a description of the amount and type of data to be read in (such,as number of flux traces and thermocouple readings, etc.); (b) a description of the reactor during the measure-ments (such as power level, inlet and outlet temperature, etc.);

(c) the actual data and information relevant to it (such as the flux thimbles that were used, neutron cross sections of the movable detectors, etc.); (d) analytical information (such as calculated thimble fluxes,calculated fuel assembly power, etc.); and (e) specification of options as to what thimbles will be employed in local power predictions, what calculations are to be done, etc.

2. Corrects raw pointwise flux measurements for leakage current, changes in power level between measu.rements, relative detector sensitivities, etc., to determine the pointwise reaction rate in the flux thimbles.
3. Compares the measured reaction rates with their design values and rejects data if they differ from expected values by more than an input rejection criteria. An error analysis is performed for subsequent determination of the uncertainty to attach to calculated peaking factors.

C.l

4. Computes the relative power produced by each fuel assembly, and in e each fuel rod chosen for attention. Local relative power is computed as:

Local Power j _ reaction Rate i] Flux Thimble Measured X rReaction Rate in Flux Thimble Analytical Average of Numerator for All Fuel in Core Local absolute power or heat flux is then computed by multiplying the,above quantity by the average specific power or heat flux in the core determined from the measured total core power at the time the data were taken. A weighted average of data from nearby thimbles can be used in determining local relative power.

5. Calculates the relative quadrant powers and the core average axial power distribution in the core. The expected and measured power peaking factors are compared for each power generating region.
6. Outputs the twenty highest values of ~Hand~ in descending order with an identifying number so that hot spot locations in the core can be determined.
7. Calculates the local heat flux hot channel factor as a function of core height and compares the values to the Technical Specification limit.
8. Calculates the rate at which burnup is being accumulated for four axial regions for each fueled area.
9. Corrects thermocouple data for calibration, and converts them to
    ~ocal enthalpy. Relative local enthalpy rise is then calculated using the vessel inlet and outlet temperatures and the core bypass C.2

flow. The local enthalpy rise measured by thermocouples is compared with that predicted from flux measurements using relative local flow rates.

10. Calculates the margin to departure from nucleate boiling (DNB) using the W-3 correlation for selected channels.
11. Lists the plant input data, the analytical parameters used, and the major calculated values.

Abnormal Occurrence Report AO-Sl-75-14 was written. SEPTEMBER a) PT-6 Control Rod Assembly Partial Movement, 9-11-75. The RPI for rod F-8 was found to be out of alignment. The 10.7-2

RPI was subsequently re-calibrated in response to e b) MR-Sl-5040. PT-13 Main Steam Safety Valve Setpoint, 9-27-75 SV-MS-104A, 101B, 103B and 104C did not lift at the correct setpoint pressure. The setpoints were adjusted and the deviation was reported in AO-Sl-75-22. c) PT-17.5 Containment Subsurface Drainage, 9-06-75. Automatic operation of the subsurface drainage system could not be verified since the fill line to the sump was inoperable. MR-Sl-4994 was written to correct this problem. d) PT-18.2 Safety Injection System Test, 9-28-75. Safety Injection master relay, SlA-A failed to latch in while testing Train A. The relay was mechanically adjusted and testing Train B, the control room exhaust fan did not trip and the inlet damper did not close when required. It was found that relay 3-VS-103A was stuck in the energized position. The spring tension of the relay was adjusted and the deviation was reported in AO-Sl-75-20. e) PT-22.3A Diesel Generator No. 1 Monthly Test, 9-03-75 The No. 1 diesel overheated during testing. It was found that the air louver controlled malfunctioned, not allowing the actuator to open the dampers. A new controller was ordered and the louvers blocked open. f) PT-27 Heat Tracing System, 9-20-75. Replacement of defective heat tape caused the actual current readings to differ from the expected current readings on several circuits. Test to be revised. 10.7-3

g) PT-29.1 Turbine Inlet Valve Test, 9-1-75. The No. 1 right reheat and intercept valves did not close when tested. MR-Sl-4814 was issued. h) PT-34 Electrical Penetration Leakage Test. 9-04 The nitrogen pressure was low on penetration B-17. The penetration was recharged.* 9-11 The nitrogen pressure was low on penetration D-2. The penetration was recharged. 9-18 The nitrogen pressure was low on penetrations E-16 and E-17. The penetrations were recharged. i) PT-36 Instrument Surveillance, 9-25-75. It was found that "B" /'-,T protection channel ,was drifting low due to steam spraying on the RTD's. The unit was shutdown for repairs. j) PT-8.5A - Consequence Limiting Safeguards Functional Test, 9-28-75. It was discovered that the inside and outside recirculation spray* pumps did not start at the designed time delay after initiation of CLS Hi-Hi. The deviation was determined to be within the limits of the safety analysis. k) PT-38.7 Chemistry Sampling - Ventilation Vent, 9-29-75. The sample on the vent showed the Iodine-131 activity exceeded 4% of the MPC while purging the No. 1 containment. The deviations will be reported in accordance with T.S.6.6.B.3. OCTOBER a) PT-26.1 Radiation Monitoring Equipment Check, 10-1-75. Meter pegged high. The detector was replaced and calibrated during the refueling outage. MR-Sl-5129 was issued. 10.7-4

b) PT-27 Heat Tracing System, 10-20-75. Circuit 13A on panels 8 & 9 had a low amperage reading. The heat tape was repaired and tested satisfactorily. MR-Sl-5563 was issued. c) PT-32.1 - HEPA and Charcoal Filter Tests, 10-15-75. Auxiliary building filter bank, l-VS-FL-3B did not meet the acceptance criteria for iodine removal efficie*ncy of 99%. All charcoal absorbers were replaced to l-VS-FL-3B and will be re-tested. d) PT-34 Electrical Penetration Leakage Test. On the dates indicated below, the following penetrations indicated a loss of pressure. In each case, the penetrations were re-charged to the correct pressure. 10-02-75 D-2, E-16 10-09-75 E-17 10-16-75 D-4, B-18 10-23-75 B-17 10-30-75 B-18, D-17, E-16, A-1 NOVEMBER a) PT-2.lA Reactor Coolant Wide Range Temperature, 11-30-75. Channel III hot leg temperature low level amplifier, TM-1-433, was out of calibration. The amplifier was replaced and recalibrated. b) PT-16.4 Containment Isolation Valve Leakage, 11-29-75. The total as found leakage was much greater than the accept-ance criteria. Several valves were repaired in order to reduce the leakage rate to an acceptable level. MOV-RS-155A & Band MOV-1860A & B required extensive working. 10.7-5

The results are detailed in a sununary technical report to the NRC. c) PT-23.1 Station Batteries, 11-30-75.

10.8 PERIODIC CONTAINMENT LEAKAGE RATE TESTS Type A, B, and C containment leak rate tests were conducted during the refueling outage commencing September 26, 1975. A containment leak rate test report containing a summary analysis and interpretation of the results of the Type A, B, and C tests was submitted to the Commission. Therefore, only a brief description of the test results are presented in this report.

a. Type "A" Testing A periodic Type "A" containment integrated leak rate test was performed during the period from October 9, 1975 to October 12, 1975.

The test yielded unsatisfactory results. The measured leakage rate was greater than the Technical Specification limit of 0.1 weight percent per 24 hours at the design basis accident pressure. The leak rate was determined to be 0.5881% by weight per 24 hours from

     *a least-squares fit analysis of 24 hourly calculations of mass (lb.)

of air in the containment. The 95% confidence factor was determined

  • to be+ 0.0219%/24 hr., giving an overall result of: L == 0.5881
      +/- 0.0219%  wt./24 hr.

During the performance of the test, major leakage was discovered from the primary to the secondary system outside the containment through leaking tubes in "A" steam generator. In addition, several containment isolation valves were leaking excessively. Local leakage tests were subsequently conducted to measure leakage re-ductions, achieved by repairs of individual leaks. The measured

      .leakage reductions were then applied to reduce the containment's
      .overall measured leakage rate to an acceptable limit. Details are contained in the summary report submitted to the Commission.

10.8-1

b. Type "B" Testing Type "B" tests were conducted following the Type A test to detect local leaks and to measure leakage across each pressure containing containment penetration. The results of the tests are listed below.
1) PT-16.2 - Containment Penetration = 20.7 SCFH Local Leakage, 11-27-75
2) PT-16.5 - Personnel Air Lock = 0 SCFH Leak Test, 11-29-75
3) PT-16.6 - Equipment Hatch 0 SCFH L~ak Test, 11-28-75
4) ST Steam Generator "A" = 1232 SCFH Tube Leakage, 10-23-75 Following the leakage measurement, the leaking tubes in "A" steam generator were plugged to reduce the leakage rate to zero.
c. Type "C" Testing Type "C" tests were conducted following the Type "A" test to measure containment isolation valve leakage rates. Several valves were repaired in order to reduce the leakage rate to ac-ceptable levels. Leakage rates were measured both before and after maintenance in order to determine the amount of leakage reduction. The total measured air leakage rate through contain-ment isolation valves before and after repairs is listed below.

Total leakage - Type "C" tests=> 1454 SCFH (PT-16.4 - Before Repairs) Total leakage - Type "C" tests= 140.7 SCFH (PT-16.4 - After Repairs) The acceptance criteria for Type "B" and "C" tests is that the combined leakage rate of all penetrations and valves be less 'than 0.60 of the maximum allowable leakage rate of 0.1 weight

%/24 hr. or 165 SCFH.
10. 8-2

Totaling the leakage measured after repairs for Type "B and "C" tests:

  .* Measured Leakage        =   20.7 SCFH (Type "B" tests)

Measured Leakage = 140.7 SCFH (Type "C" tests) Total (After repairs) = 161.4 SCFH Since the total measured leakage after repairs for Type "B" and "C" tests is less than 165 SCFH, the leakage rate has been reduced to acceptable limits.

SUMMARY

Surry Unit 2 has completed six months of Cycle 2 operation. Since Cycle 2 initial criticality on June 14, 1975, the reactor core has produced some 35 x 10 6 MBTU (6,090 Megawatt days per metric ton of contained uranium) which has resulted in the generation of over 3.2 x 10 9 kwhr of electrical energy. The purpose of this report is to present an analysis of the core performance for routine operation during Cycle 2. Non-routine operation was covered in the Surry 2-Cycle 2 startup physics test report 1 and, therefore, will not be included here. Routine core follow involves the analysis of four principal perfor-mance indicators. These are burnup distribution, reactivity depletion, power distribution, and primary coolant activity. The core burnup distribution is followed to verify both burnup symmetry and proper.batch burnup sharing, thereby ensuring that the fuel held over for the next cycle will be compatible with the new fuel inserted. Reactivity depletion is monitored to: detect the existence of any abnormal reactivity behavior, determine if the core is deplet-ing as designed, and indicate at what burnup level refueling will be required. Core power distribution follow includes the monitoring of nuclear hot channel factors to verify that they are within the limits of the Technical Specifica-tions, thereby ensuring that adequate margins to linear power density and critical heat flux thermal limits are maintained. Lastly, as part of normal core follow, the primary coolant activity is monitored to assess the integrity of the fuel. In addition to the above, the effects of fuel densification were monitored. Although not normally part of routine core follow, this phenomenon is treated here because of its impact on core performance. e 1Lippard, D, W., and Keck, S.

Each of the four performance indicators, as well as the status of observed fuel densification effects, is discussed in detail for the Surry Unit 2 Cycle 2 core in the body of this report 2

  • The results are summarized below:
1. Burnup Follow - The burnup tilt (deviation from quadrant symmetry) on the core is less than+/- 0.2% with the burnup accumulation in each batch generally within 3% of design prediction.
2. Reactivity Depletion Follow - The critical boron concen-tration, used to monitor reactivity depletion, has consis-tently been within+/- 0.4% ~K/K of the design prediction which is well within the+/- 1% ~K/K margin allowed by Section 4.10 of the Technical Specifications.
3. Power Distribution Follow - Incore flux maps taken each month indicate that the radial power distribution was generally within+/- 4% of the design prediction with all hot channel factors meeting the Technical Specifications limits.
4. Primary Coolant Activity Follow - The iodine-131 activity level in the primary coolant is approximately 2.0 x 10- 2
                µCi/ml, which indicates that there are approximately three to five defects in the fuel. This corresponds to approxi-mately a 99.99% fuel integrity factor.
5.
  • Fuel Densification Status - There is only one confirmed assembly location with a power spike due to pellet gap formation; this spike is very small, that is;less than 1%

in magnitude. 2 see Appendix A for definition of terms used in this report. 2

Section 2 CORE PERFORMANCE ANALYSIS 2.1 Burnup Follow The burnup history for the Surry Unit 2 Cycle 2 core is graphically depicted in Figure 2.1.1. To date, the core has accumulated a burnup of 6,090 MWD/MTU. As shown in Figure 2.1.2, the average Surry 2-Cycle 2 load factor has been 88% when referenced to rated thermal power (2441 MW(t)). Radial (X-Y) burnup distribution maps show how the core burnup is shared among the various fuel assemblies, and thereby allow a detailed burnup distribution analysis. The TOTE computer code (see Appendix B) is used to calculate these assemblywise burnups. Figure 2.1.3 is a radial burnup distri-bution map in which the assemblywise burnup accumulation of the core as of December 31, 1975, is given. For comparison purposes, the design values are also given. As can be seen from this figure, the accumulated assembly burnups are generally within+/- 3% of the predicted values . . In addition, deviation from quadrant symmetry in the core, as indicated by the burnup tilt factors, is less than+/- 0.2%. As shown in Figure 2.1.4, the various assemblies are grouped together into batches according to their nuclear characteristics and residence time in the reactor. The burnup sharing on a batch basis. is monitored to verify that the core is operating as designed and to enable accurate end-of-cycle batch burnup predictions to be made for use in reload fuel design studies. As seen in Figure 2.1.5, the batch burnup sharing for Surry Unit 2-Cycle 2 is following design predictions very closely with each batch deviating less than 3% from design; this is considered excellent agreement. Therefore, symmetric bm:nup in conjunction with: .good. a;gree~ent between actual and predicted assemblywise burnups and batch burnup sharing indicate that the Cycle 2 core is depleting as designed. 3

2.2 Reactivity Depletion Follow T.he I;>rimary coolant critical boron concentration is monitored for the purposes of following core reactivity and flagging any anomalous reactivity behavior. The FOLLOW computer code (see Appendix C) is used to normalize "actual" critical boron concentration to design conditions taking into consider-ation actual control rod positions, xenon and samarium concentrations, moder-ator temperatures, and power levels. The normalized critical boron concentra-tion versus burnup curve for the Surry Unit 2 Cycle 2 core is shown in Figure 2.2.1. It can be seen that the measured data compare within +/- 30 to 35 ppm of the design prediction. This corresponds to within+/- 0.4% ~K/K which is well within the+/- 1% ~K/K criteria for reactivity anomalies set forth in Section 4.10 of the Technical Specifications. In conclusion, the trend indicated by the critical boron concentra-tion verifies that the Cycle 2 core is depleting as expected with no reactivity anomalies. 2.3 Power Distribution Follow Analysis of incore flux map data on a routine basis is necessary to verify that the hot channel factors are within their Technical Specifications limits and to ensure that the reactor is operating with no abnormal conditions which could cause an "uneven" burnup distribution. Three dimensional core power distributions are determined by analyzing the data from movable detector flux map measurements using the INCORE computer program (see Appendix D). A summary of all flux maps taken since completion of the startup physics tests for Surry Unit 2 Cycle 2 is given in Table 2.3.1. Incore flux maps are gener-ally taken monthly with additional maps taken as needed. Radial (X-Y) core power distributions for a representative series of incore flux maps are given in Figures 2.3.1 through 2.3.3. All of the radial maps shown were taken under near equilibrium operating conditions with the Unit 4

operating*at approximately full power. In each case, the measured relative assembly powers are generally within 4% of the predicted values, which is considered good agreement. In addition, as indicated by the INCORE tilt factors, the power distributions are essentially symmetric for all cases. An important aspect of core power distribution follow is the moni-toring of nuclear hot channel factors. Verification that these factors are within Technical Specifications limits ensures that linear power density and critical (DNB) heat flux limits will not be violated, thereby providing adequate thermal margins and maintaining fuel cladding integrity. The current Technical Specifications limits on the axially dependent T heat flux hot channel factor, FQ(Z), is 2.10 x K(Z), where K(Z) is given in Figure 2.3.4. The axially dependent heat flux hot channel factor for a representative series of flux maps is given in Figures 2.3.5 through 2~3.7. For all maps taken thus far in Cycle 2, the F~(Z) measured values are within the Technical Specifications limit. A summary of the maximum values of all heat flux hot channel factors measured thus far in Cycle 2 is given in Figure 2.3.8. Peak linear power density, which is determined directly from maximum F~ is given in Figure 2.3.9. This is an important parameter from a loss-of-* coolant accident-ECCS standpoint since it directly relates to the stored thermal energy .in the core. The Surry Unit 2 Cycle 2 core has maintained a peak linear power density of at least 8% below the nominal allowable limit. N A radial hot channel factor routinely followed is F~H' the enthalpy rise hot channel factor, which is the ratio of the integral of power along the rod with the highest integrated power to that of the average rod. The Technical Specifications limit for this parameter is set such that the critical heat flux (DNB) limit will not be violated. Figure 2.3.10 shows that all measured values were within the Technical Specifications limit. 5

Another radial hot channel factor routinely monitored is F , the xy horizontal plane peaking factor. This peaking factor is a ratio of the peak to average power in a given horizontal plane. It is related to, but is not

              . N identical to, F~H*      As shown in Figure 2.3.11, the measured F       peaking factors, xy evaluated at core*midplane, deviate from the nominal design prediction, by less than 2%, which is well within the design uncertainty of 8%.         The model used to generate the analytic factors that are used to reduce the incore flux map data was changed at 4,500 MWD/MTU burnup.        This model change resulted in a reduction in the values of F       .

xy The Technical Specifications require that target delta flux 3 values be determined monthly. Operational delta flux limits are then established about this target value, and by maintaining a relatively constant delta flux, adverse axial power shapes due to xenon redistribution are avoided. The plot of delta flux versus burnup given in Figure 2.3.12 shows the delta flux shifting from approximately +4% at the beginning of the cycle to approximately 0% at 1,900 MWD/MTU where it remains relatively constant throughout Cycle 2. The shift can also be observed in the corresponding core average axial power distributions for a representative series of maps given in Figures 2.3.13 through 2.3.15. In Map S2-2-6 (Figure 2.3.13) taken at 170 MWD/MTU, the axial power distribution peaks slightly toward the top of the core with a peaking factor of 1.22. In Map S2-2-12 (Figure 2.3.14) taken at 2,790 MWD/MTU and .Map S2-2-17 (Figure 2.3.15) taken at 5,650 MWD/MTU, the axial power distribu-tion has flattened slightly as expected with axial peaking factors of 1.14 and 1.11, respectively. The gradual decrease and leveling off of F can be seen z 3Delta Flux Pt - Pb

more clearly in a plot of F versus burnup given in Figure 2.3.16. This plot z agrees well with design predictions which indicate that Fz decreases from 1.19 to 1.13 throughout the cycle. In conclusion, the Surry 2 Cycle 2 core performed very satisfactorily with power distribution analyses verifying that design predictions are accurate and that hot channel factors are meeting Technical Specification limits. 2.4 Primary Coolant Activity Follow Activity levels of iodine-131 and 133 in the primary coolant are important iri core performance follow analyses because they are used as indi-cators of defective fuel. These two isotopes can leak into.the primary coolant system through a breach in the cladding. I-131 activity is directly correla-table to the *number of cladding defects; the ratio of I-131 to I-133 is used to determine the type of fuel failure which has occurred in the reactor core. Use of the ratio for this determination is feasible because 1-133 has a short half-life (approximately 24 hours) compared to that of I-131 (approximately eight days) so that for pinhole defects where the diffusion time through the defect is on the order of days, the I-133 decays out leaving I-131 dominant in activity, thereby causing the ratio to be 0.5 or more. In the case of large leaks, uranium particles in.the coolant, and/or "tramp" 4 uranium, where the diffusion mechanism is negligible, the I-131/I-133 ratio will generally be less than 0.1. Figure 2.4.1 shows the I-131 activity history for the Surry Unit 2 Cycle 2 core with the FSAR value for various defect levels 5 (one defect is equivalent to one defective rod} delineated for comparison purposes. The data t+"Tramp" uranium consists of small. particles of uranium which adhere to the outside surface of the fuel during the manufacturing process. .e 5 This is derived from FSAR Table 9.1-5 where cladding defects in 1% of the fuel rods gives an 1~131 primary coolant activity concentration of 1.68 µCi/ cc@ 560 0 F. Samples are analyzed at room temperature; hence, this value is 2.35 µCi/cc when a density correction is made. 7

show considerable scatter, but the trend indicates that approximately three to five defective fuel rods exist in the core, indicating that Surry Unit 2-Cycle 2 has a fuel integrity factor of -99.99%. This is substantially below the Technical Specifications limit of 1% failed fuel which is equivalent to approximately 320 defects. As shown in Figure 2.4.2, the I-131/1-133 ratio data points fall in the mid-range, thus giving no indication as to the type of defect. 2.5 Fuel Densification Status Throughout Cycle 1 the densification induced power spikes were primarily observed in Region 1 fuel; this fuel was removed from the core during the Cycle 1-2 refueling. The effects of fuel densification in Surry 2 Cycle 2 have been insignificant with only one observable power spike present. This confirmed 6 power spike is in core location F-6, a region 3 fuel assembly, and is extremely small, that is less than 1% in magnitude. The latest strip chart trace for F-6 is given in Figure 2.5.1. 6A confirmed power spike is one which has been observed in two or more recent flux maps. A suspected power spike is one which has been observed generally only in the most recent map. 8

61 1 BOTTOM CORE POSITION (NODES) TOP 34

CONCLUSIONS The Surry Unit 2-Cycle 2 core has operated for over half of its normal cycle with all performance indicators comparing closely to design predictions and all Technical Specifications limits being met. No abnormali-ties in core.reactivity, power distributions or burnup accumulation have been detected. Radioiodine analyses for Cycle 2 indicates that several fuel defects have occurred; however, the number of defects is small and the integrity of the core remains quite acceptable. As anticipated, fuel densification power spikes have been insignificant during Cycle 2. 35

Appendix A DEFINITION OF TERMS ACTIVITY - Number of nuclear disiritegrations ~er unit time taking place in a radioactive nuclide. Usually expressed in terms of 4

          µCi (3.7 x 10 disintegrations per second).

AXIALLY DEPENDENT HEAT FLUX HOT CHANNEL FACTOR -FQ(Z)- The maximum local heat flux on the surface of a fuel rod at a core elevation Z divided by the average fuel rod heat flux. AXIAL OFFSET - The percent difference between the fraction of total core power produced in the upper half of the core and that produced in the lower half of the core. BATCH - A group of assemblies which are inserted into the reactor at the same time. All of the assemblies in a batch may or may not have the same nuclear characteristics or be discharged at the same time. (See REGION) BORON (Soluble) - A strong neutron absorber which is dissolved in the reactor coolant and used for reactivity control. The boron concentration in the coolant is expressed in terms of parts per million water (ppm). BURNUP - The quantity of energy produced per unit weight of fueL It is a measure of fuel consumption and typically has units of megawatt-days per metric ton of initially contained uranium (MWD/MTU). CRITICAL - Condition in which the neutron chain reaction in a reactor is just self-sustaining. CRITICAL BORON CONCENTRATION - The concentration of soluble boron in the coolant at which the reactor is just critical. CRITICAL HEAT FLUX (DNB) - The point of transition between nucleate boil-ing and film boiling at the coolant-clad interface. Beyond this critical heat flux point, a vapor blanket forms on the cladding surface and acts as an insulator, thereby resulting in abnormally high clad temperatures. DENSIFICATION - A recently discovered phenomenon in which the UQz fuel pellets shrink both radially and axially as a result of neutron irradiation. DENSIFICATION-INDUCED GAPS - When a column of UOz pellets in a fuel rod shrinks due to densification, gaps may be formed in the pellet column. FISSION PRODUCTS - Residual nuclei which are generated during the fission process and which retain nearly all of the energy formed in the process.

FLUX (NEUTRON) - A measure of the intensity of neutrons, i.e., the number of neutrons passing through one square centimeter in one second. FLUX MAP - A three-dimensional representation of the flux distribution throughout the core. It is obtained from measurements made with the movable detector system. (See MOVABLE DETECTOR) HALF-LIFE - Period of time in which a radioactive element decays to half its original concentration. IODINE-131; IODINE-133 - Fission products which, because of their radio-active and chemical properties, can be used to determine fuel clad defects. LINEAR POWER DENSITY - Power generated per unit length of fuel rod. This parameter is a measure of the central temperature of the fuel rod and stored heat. Usually expressed in units of Kw/ft. LOAD FACTOR - The ratio of the actual reactor energy generated over a period of time to the *potential energy which could have been generated by the reactor over that same period of time. MOVABLE DETECTOR - A traversing incore fission chamber which generates a voltage signal proportional to the flux level the chamber "sees". Five such detectors are moved at one time through the core to monitor the flux distribution. A total of 50 locations are -traversed to generate a complete flux map of the core (See FLUX MAP) NODE - The core is divided into 60 equally spaced axial segments by the movable detector monitoring system. Nodal representation is then used by the INCORE program in deriving the power distribut_ions. POWER DENSITY - Power generated per unit volume in the core. Usually expressed in units of Kw/Liter. POWER SPIKE - A local increase in power due to densification-induced gaps in the pellet stack. RADIAL POWER MAP - An X-Y distribution of power on an assembly basis, normalized to the average assembly power. REACTIVITY - In a nuclear reactor, a measure of the departure from a just critical condition. Usually expressed in units of pcm (10-5 ~K/K), it is normal to refer to a pcm quantity of reactivity associated with some component of the reactor since removing that component will change the reactivity of the reactor by that amount.

REGION ...: A group of assemblies which have essentially the same nuclear design characteristics and are inserted into the reactor at the same time. (See BATCH) TECHNICAL SPECIFICATIONS - The document setting forth mandatory operational and surveillance requirements for a nuclear facility. It is issued by the NRC as part of the operating license. TILT - A deviation from perfect symmetry. Usually used with respect to radial burnup or power distributions and relates each

            *quadrant to the average of all four quadrants.

XENON - A gaseous fission product which has a very strong neutron absorption capability. Unless controlled, the xenon concentration can shift up and down the axial axis of the core, thereby causing axial power transients. t:, K/K - Mathematical expression for reactivity, where "K" is the ratio of the number of neutrons present in a reactor in any one neutron generation to that in the immediately preceding generation. (See REACTIVITY)

Appendix B TOTE PROGRAM DESCRIPTION TOTE is an isotopic and burnup follow computer program written by the Westinghouse Electric Corporation to accurately keep track of the iso-topic content of the fuel and the accumulated fuel burnup. It is presently operational on the Virginia Electric and Power Company's IBM-370 computer system. In the analysis of in-core flux maps the INCORE code punches out burnup rate information for every fuel region. These regions normally include each fuel assembly (and fueled follower) and about one hundred indi-vidual fuel rods of interest. The burnup rate is given as the megawatt-hours generated in a given fuel region per 1000 megawatt-hours generated by - the core. The total for each fuel region is given as well as the value for each of four axial segments of approximately equal length. In addition, the core average axial power distribution is punched out. The TOTE user inputs: .(a) the core energy (megawatt-hours) associated with each of the above burnup rate decks; (b) cards describing each fuel region (including MTU, corresponding INCORE source number, previous burnup, isotopic depletion type, etc.); (c) tables of the change in isotopics (U-235, U, Pu, etc., up to ten constituents) with burnup; and, (d) the burnup rate decks from INCORE. Printed output includes a listing of the input; core, cycle and fuel region burnup; fuel assembly isotopics; the energy weighted core average.axial power distribution; and the initial and current uranium concentrations for each fuel batch and the core. Isotopic concentrations of the fuel assemblies are obtained by a quadratic interpolation of the data which is contained as part of the input isotopic table sets. Punched output c6nsists of Item (b) above for subsequent TOTE runs.

Appenctix.c FOLLOW PROGRAM DESCRIPTION FOLLOW is a data analysis computer program written by Westinghouse Electric Corporation to process reactor operation data and calculate critical boron concentrations for the reactor operating under nominal conditions. It is presently operational on the Virginia Electric and Power Company's IBM-370 computer system. The FOLLOW Code describes the nearly linear relationship between available core reactivity and cycle burnup. It is most convenient to use boron as a measure of core reactivity with off nominal* corrections being made for power level, xenon and samarium concentrations, coolant temperature, and control rod position in terms of their boron worth. These corrections are made as can be seen from this equation: off nominal corrected or measured reactivity correction nominal boron= boron due to rod group concentration concentration [ 1 position off nominal off nominal

      +     reactivity correction     +        reactivity correction due to rod group                    due to moderator 2 position                          temperature
      +

off nominal reactivity correction + off nominal reactivity correction J due to power due to xenon and samarium behavior Options are chosen so as to satisfy the above equation in ways appropriate to the condition of the reactor and its method of operation. The boric acid concentration in the primary loops of operating PWR's is typically measured one to three times per day. After proper normalization, this data is plotted against cycle burnup and forms the "boron depletion curve."

  • Nominal conditions generally mean hot full power equilibrium conditions with control rods out of the core.

Since this curve is well behaved and nearly linear from beginning to end of the cycle, it can provide the following information:

1) Detection of abnormal (unexpected) behavior in core reactivity. The power station Technical Specifications require boron follow for this purpose.
2) Extrapolation to end-of-cycle life for scheduling refueling, or determina-tion of end-of-life for contractual purposes.
3) Rate of.loss of reactivity with burnup for confirmation of design para-meters.
4) Indication of the need for updating reactivity coefficients needed for plant operation.
5) Best estimate of beginning of cycle, hot-full-power criticality under equilibrium conditions.

Appendix D INCORE PROGRAM DESCRIPTION INCORE is a data analysis computer program written by the Westinghouse Electric Corporation to process information obtained by in-core instrumentation. It is presently operational on the Virginia Electric and Power Company's IBM-370 computer system. In the reduction of in-core flux and temperature measurements the INCORE code performs the following:

1. Reads input consisting of (a) a description of the amount and type of data to be read in (such as number of flux traces and thermocouple readings, etc.); (b) a description of the reactor during the measure-ments (such as power level, inlet and outlet temperature, etc.);

(c) the actual data and information relevant to it (such as the flux thimbles that were used, neutron cross sections of the movable detectors, etc.); (d) analytical information (such as calculated thimble fluxes,calculated fuel assembly power, etc.); and (e) specification of options as to what thimbles will be employed in local power predictions, what calculations are to be done, etc.

2. Corrects raw pointwise flux measurements for leakage current, changes in power level between measurements, relative detector sensitivities, etc., to determine the pointwise reaction rate in the flux thimbles.
3. Compares the measured reaction rates with their design values and rejects data if they differ from expected values by more than an input rejection criteria. An error analysis is performed for subsequent determination of the uncertainty to attach to calculated peaking factors.
4. Computes the relative power produced by each fuel assembly, and in each fuel rod chosen for attention. Local relative power is computed as:

j r Local Power eaction Rate i j Flux Thimble Measured X rReaction Rate in Flux Thimble Analytical Average of Numerator for All Fuel in Core Local absolute power or heat flux is then computed by multiplying the above quantity by the average specific power or heat flux in the core determined from the measured total core power at the time the data were taken. A weighted average of data from nearby thimbles can be used in determining local relative power.

5. Calculates the relative quadrant powers and the core average axial power distribution in the core. The expected and measured power peaking factors are compared for each power generating region.
6. Outputs the twenty highest values of F~H and F~ in descending order with an identifying number so that hot spot locations in the core can be determined.
7. Calculates the local heat flux hot channel factor as a function of core height and compares the values to the Technical Specification limit.
8. Calculates the rate at which burnup is being accumulated for four axial regions for each fueled area.
9. Corrects thermocouple data for calibration, and converts them to local enthalpy. Relative local enthalpy rise is then calculated using the vessel inlet and outlet temperatures and the core bypass

flow. The local enthalpy rise measured by thermocouples is compared with that predicted from flux measurements using relative local flow rates_.

10. Calculates the margin to departure from nucleate boiling (DNB) using the W-3 correlation for selected channels.
11. Lists the plant input data, the analytical parameters used, and the major calculated values.

MR-S2-4620 was issued. f) PT-34 Electrical Penetration Leakage Test, 9-3-75. The nitrogen pressure was low on penetration A-18~ The penetration was recharged to the correct pressure. g) PT-36 Instrument Surveillance 9-06-75 - The RPI for rod H-14 was out of alignment and required re-calibration. 9-17-75 - The RPI's for rods E-5 and F-12 were out of alignment and required re-calibration. OCTOBER a) PT-2.1 Overpower - Overtemperature Protection, 10-2-75. The output of TM-2-422E drifted low causing the output of 11.7-3

the overtemperature setpoint summator to read high approximately 1% in the unconservative direction. Technical Specification settings were not violated. Delta flux function generator, NM-2-432C, drifted out of spec in the conservative direction. The module was replaced and recalibrated. b) PT-2.1 Overpower - Overtemperature Protection, 10-30-75. The output of delta flux function generator, NM-2-432C, drifted high causing the overtemperature setpoint to be low which is conservative. The module was replaced and recalibrated. c) PT-5.1 Analog Rod Position Instrumentation, 10-23-75. The rod bottom bistable for rod K-6 was out of alignment and could not be adjusted. The bistable was replaced and recalibrated. d) PT-15 Steam Generator Auxiliary Feedwater System, 10-4-75. Steam inlet valve, MOV-MS-202, would not open electrically. A deviation report was submitted and MR-S2-4693 was issued. e) PT-17.2 - Inside Recirculation Spray Pumps. This test was not completed as scheduled. The unit was shutdown on the last day of the grace period, 10-9-75, then started up prior to completion of the test. The test was completed on 10-14-75 and a deviation report was written. f) PT-26.1 - Radiation Monitoring Equipment Check, 10-1-75. RM-RMS-262 was out of service during the month. The detector will be repaired at cold shutdown. g) PT-34 Electrical Penetration Leakage Test. On the dates listed below, the following penetrations 11.7-4

indicated a loss of pressure. In each case, the penetrations were recharged to the correct pressure. 10-01-75 A-18 10-08-75 D-9, D-2, D-1 10-29-75 B-1, A-18 NOVEMBER a) PT-5.1 Analog Rod Position Instrumentation 17-75. The rod bottom bistable for rod D-10 tripped low at 10 steps. The bistable was reset to trip at 20 steps. b) PT-26.1 Radiation Monitoring Equipment Check. The manipulator crane radiation monitor, RM-RMS-262, was'out of service during the month. The detector will be repaired at cold shutdown. c) PT-29.1 Turbine Inlet Valve Test, 11-30-75.

In each case the penetrations were recharged to the correct pressure. 11-05-75 B-1, A-15, A-18 11-26-75 D-2, D-9, A-15, E-16 DECEMBER a) PT-1.4 - NIS Trip Channel Test at Power, 12-2-75. The output from log amplifier, NM-201, was low and could not be properly adjusted. The defective module was replaced and recalibrated. The low amplifier output

11. 7-5

caused the indicated power te be low and thus altered the intermediate range hi flux rod stop and reactor trip setpoints. No start-ups were conducted since the last test, however, therefore this protection is required. b) PT-2.10 - Feedwater Flow, 12-10-75. Multiplier/Divider, FM-2-476, was replaced and recali-brated due to excess noise. c) PT-18.5 - Hi Head Safety Injection and Flushing of Stainless Steel Piping, 12-7-75.
