3.0 UNIT DESCRIPTION Surry Unit Two is a Pressurized Water Reactor rated at 2441 MWth. Two similar units (Units 1 and 2) are located at the site in Surry County, Virginia, p The containment structure is a steel-lined, reinforced-concrete cylinder with a hemispherical dome and a reinforced-concrete foundation mat. Containment 4

volume is 1.8 x 10 6 ft 3 . Containment design pressure is 45 psig which is sufficient to withstand the f

internal pressure from a design-basis accident (DBA).

i It has been calculated that the peak accident pressure and temperature from a DBA are 44.2 psig and 2850 F respectively.

SUMMARY

xs 4.1 TYPE A TEST The CILRT that was performed on Surry Unit Two was satisfactorily completed on November 20, 1986. The final Upper Confidence Limit (UCL) leakage results, including the required penalties, was .063838 wt%/ day.

This value is well below the acceptable limit of .075 wt%/ day and clearly demonstrates that the integrity of the containment has met the criteria in Paragraph III . A. 5. (b) . (2 ) of Reference 1.1.

Containment pressurization began at 2335 hours0.027 days 0.649 hours 0.00386 weeks 8.884675e-4 months on November 17, 1986. Pressurization continued until 0905 hours0.0105 days 0.251 hours 0.0015 weeks 3.443525e-4 months on November 18, 1986. Prior to the start of pressurization, Penetration 70, MOV-RS-256B, was blanked off due to excessive seat leakage on the valve.

() It was decided that the valve would be worked after the Type A test since the amount of time required to repair the valve would delay the start of the Type A test. The post-repair Type C test minimum pathway leakage results for that penetration were added to the final Type A test results. The valve had an As-Left leakage of 3.7 SCFH. A minimum pathway leakage of .000261 wt%/ day was added to the final UCL leakage results. l During the course of the stabilization period, walkdowns were performed on various areas to identify any possible leakage paths. Four vented penetrations c

(T) 4.1 TYPE A TEST (CONT) in the Auxiliary Building were identified as leaking past their open leakage monitoring connections (LMC).

The total leakage for these penetrations was quantified as 6.93 SCFH.

Also during the stabjAization period, a change in CC temperature occurred at approximately 1905 hours0.022 days 0.529 hours 0.00315 weeks 7.248525e-4 months on November 18, 1986, causing a spike in containment mass, dewpoint temperature and containment average temperature. It was later determined that this change in CC temperature was caused by an additional heat load being placed on the CC system. Containment conditions started to restabilize at 2055 hours0.0238 days 0.571 hours 0.0034 weeks 7.819275e-4 months on November 18, 1986. At 0500 hours0.00579 days 0.139 hours 8.267196e-4 weeks 1.9025e-4 months on November 19, 1986, containment was declared stabilized. The stabilization conditions of Attachment 7.13 in Reference 1.3 were satisfied.

,~m N-During the course of the Type A test, containment leakage averaged approximately -11 lbm/hr for the first nine hours of the test. The rate of change in mass then decreased and became relatively stable for the next 23 hours2.662037e-4 days 0.00639 hours 3.80291e-5 weeks 8.7515e-6 months , averaging approximately -3.96 lbm/hr.

This trend in mass can be seen on Figure 7.1. During the performance of the Type A test, walkdowns were periodically performed to identify any problem areas.

No significant discrepancies were noted during these walkdowns. i

() 4.1 TYPE A TEST (CONT)

Actual containment leakage, see Attachment 7.1, was

.062 wt%/ day at the beginning of the test and was .029 wt%/ day at the end of the test. This variance resulted in the confidence limit being higher than normal. The Type A test was extended for 32 hours3.703704e-4 days 0.00889 hours 5.291005e-5 weeks 1.2176e-5 months to allow the confidence limit to continue a slow but steady decrease to within acceptable limits.

A major contribution to the extended test duration was the use of instantaneous data (containment pressure, dewpoint temperature and average temperature) from the P250 computer instead of the ten minute averaged values which were used on previous CILRTs. The instantaneous values had more scatter than we had normally seen with the averaged values. If the program that utilized averaged values was used, the Type A test

() could have been satisfactorily completed in approximately 20 hours2.314815e-4 days 0.00556 hours 3.306878e-5 weeks 7.61e-6 months using the same UCL leakage as in I

the instantaneous test results (See Attachment 7.2).

l The Type A test was satisfactorily completed at 1300 hours0.015 days 0.361 hours 0.00215 weeks 4.9465e-4 months on November 20, 1986 with a UCL leakage of

.063451 wt%/ day. With the Type C test penalties added to the test results, the final leakage was .063838 wt%/ day.

The superimposed verification test was started at 1330 hours0.0154 days 0.369 hours 0.0022 weeks 5.06065e-4 months on November 20, 1986 with a leakage of i approximately 5.00 SCFM being registered on the flow meter. The stabilization period for the verification test ended at 1535 hours0.0178 days 0.426 hours 0.00254 weeks 5.840675e-4 months . At that time, leakage rate

calculations were started.

2.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months of the verification test remained relatively stable, see Figure 7.3.

l 5.4

() 6.0 TEST DESCRIPTION 6.1 EQUIPMENT USED The containment was pressurized utilizing a temporary air pressurization rig which tied into containment ventilation ductwork. The rig consisted of 8 diesel driven oil-free air compressors, 2 aftercoolers and 1 air dryer. The rig was capable of supplying up to 10,000 SCFM to containment during the pressurization phase. Cooling water for the aftercoolers and air dryer was supplied by the station's Chilled CC system.

The rig was satisfactorily checked out prior to pressurization in accordance with Attachment 7.7 of Reference 1.3.

Containment temperature was monitored throughout the Type A test by the use of 22 permanently mounted RTDs

() whose output is fed to the P250 computers. The normal span of these RTDs(0-750 F) was changed for the test by utilizing a temporary resistance bridge that was installed on the P250 computer. The span was narrowed l to 55-105 F to allow for greater sensitivity in recording containment temperature.

Station calibration procedure 2-TCAL-664 was performed on the RTDs input signal to the plants P250 computers.

A decade box was temporarily installed on the P250 l computer which simulated the resistance reading for each RTD inside containment. The computer was then checked to ensure that the program output for each RTD was obtained when the resistance was varied. A one point check of the RTDs using a standard traceable to NBS was performed prior to the Type A test using l l 6.1 C)

i s

f"%

\] 6.1 EQUIPMENT USED(CONT) station procedure PT-16.3D. This check ensures that the reading from the P250 computer corresponds to the actual RTD temperature by the RTD. If the deviation between the actual RTD temperature and the temperature of the standard is greater then +1.0 F, the entire calibration curve for the RTD is shifted to correspond to the temperature of the standard.

Containment dewpoint temperature was monitored by 5 Ondyne moisture analyzer probes located throughout containment. Readout devices with a tie in to the P250 computers were located in the electrical penetration area. The Ondyne analyzers use the principle whereby the temperature of a detecting surface on the probe is cooled by a thermoelectric device to the point where condensation forms. When the condensation is detected, w

1 cooling is controlled to hold the surface at the condensation temperature and then the surface temperature is measured using a platinum RTD. This surface temperature is the dewpoint temperature of the air next to the probe.

The moisture analyzers were calibrated within six months of the Type A test by the vendor and their accuracy was certified as being traceable to NBS. An additional w

one point check was performed for each analyzer using ctation procedure PT-16.3D.

Containment pressure was monitored by the use of two Mensor Quartz manometers. These manometers tie into the Containment Leakage Monitoring (LM) system through LMCs on the 13' level of the Auxiliary Building. The 6.2

6.1 EQUIPMENT USED(CONT) signal from these manometers is fed into the P250 computers. The manometers were calibrated within six months of the Type A test by the original manufacturer with the accuracy being certified as being traceable to NBS.

A Hastings linear mass flowmeter was used to monitor i

flow for the superimposed verification test which proceeded the Type A test. The flowmeter measures flow without any corrections being needed for pressure and temperature. Flow is displayed and totalized at j the flowmeter which is installed in the LM system on i the 13' level of the Auxiliary Building. The LM piping then ties into the Service Air (SA) piping penetration which is vented inside containment. The flowmeters accuracy was certified as being traceable to NBS by

() the original manufacturer within six months of the Type A test.

Attachment 6.1 lists pertinent information for the instrumentation that was used during the Type A test.

6.2 CILRT PROGRAM - P250 COMPUTER The ILRT program on the P250 computer gathers and logs the required data during the Type A test. The data is printed out in log format which is then input into the ILRT analysis program on the IBM-PC.

The ILRT program on the P250 computer consists of three sub-programs. These programs are run on both units P250 computers during the Type A test. The program on 6.3 0

{n) 6.2 CILRT PROGRAM - P250 COMPUTER (CONT)

Unit One's computer would be used as a backup if Unit Two's computer fails. The three programs are MANOS, ILRTDAT2 and ILRTPRT2. A brief description of each program follows.

The MANOS program is used to convert the BCD output of the quartz manometers into floating point numbers.

MANOS program reads six BCD digits for each quartz manometer via a direct channel read and converts these BCD signals into floating point values which are placed in calculated points UO962 and U0963 of the P250 computer. Each quartz manometer is scanned on a two second frequency.

The ILRTDAT2 program uses the 22 containment RTD readings, 5 moisture analyzer readings and 2 pressure

() readings to apply the appropriate weighting factors and to perform sensor validity checks. These values are obtained from the P250 Average and Integrate (A&I) program which calculates a simple average for each of the twenty-nine sensors by summing the instantaneous readings taken during a ten minute period and dividing the totals by the number of readings taken. The RTDs' and moisture analyzers are scanned every 20 seconds by the A&I program.

The ILRTDAT2 program also performs sensor checks by checking the difference between the ten minute averages of sensors within the same zone against a maximum limit. When the maximum limit is exceeded, the program notifies the operator via an error message printed out '

on the alarm typewriter to check the zone. If a sensor 6.4 Qj

(j 6.2 CILRT PROGRAM - P250 COMPUTER (CONT) has malfunctioned, the operator can direct the program to stop scanning the faulty sensor and to reassign the failed sensors weight factor to the remaining sensors in its zone.

The ILRTPRT2 program generates a formatted log of the ILRT data that is gathered by the ILRTDAT2 program.

The program is bid every ten minutes by the ILRTDAT2 program or manually via the operators console.

Additional changes were made to the P250 ILRT program prior to the Type A test as requested by the NRC inspector. This involved modifying the program such that instantaneous data was printed out every ten minutes along with the average data as was done in previous Type A tests.

(D LJ 6.3 CILRT PROGRAM - PC COMPUTER The Type A test program on the PC computer is used to calculate and plot the change in mass of containment versus time. Input data for the program is obtained from the plant process computer (P250) data collection program. The variables which are manually input into the PC program are time, containment pressure, dewpoint temperature and containment temperature.

The variables are stored in a data file when input into the program. The user then has the option of performing various subroutines which enable the user to calculate results, list data set members, input additional data set members, modify existing data set members and to delete data set members which are not needed.

6.3 CILRT PROGRAM - PC COMPUTER (CONT)

In the calculation mode, the user has the option of performing either mass point, total time or point-to-point analysis. Total time was the only method used for this test since it is the only method accepted by the NRC at this time.

The total time method of analysis calculates containment mass for each data set that is input into the PC program. Mass is calculated using the ideal gas law equation as listed below:

3, (P-Pv) (Vc) (144)

RT Where: M= Containment mass Lbm

() P= Containment pressure Psia Pv= Containment vapor pressure Psia Vc= Containment free volume ft 3 R=53.35ft-lbf/lbm- R T= Containment average temperature R 144= Conversion constant 6.6 O

(

6.3 CILRT PROGRAM - PC COMPUTER (CONT)

The measured leakage rate is then calculated for each data set by subtracting the final mass from the initial mass, dividing by the time interval and then dividing by the initial mass. The leakage rate is expressed as the fraction of containment mass lost for 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months and is listed below:

Measured Leakage Rate (wt%/ day)=( ) / (Ti-To) (-2400)

Mo Where: Mi= Final mass at time Ti Mo= Initial mass at time To Ti= Final time To= Initial time The sign convention for this equation is such that a

() negative value indicates leakage into containment and a positive value indicates leakage out of containment.

The method of least squares is then utilized to find the best fitting straight line through the measured leakage rate values. The estimated leakage rate at some specific time (t) is then expressed as a function of the form:

Li = A + Bti Where: Li= Estimated leakage rate (wt%/ day)

A= Intercept of the measured leakage rate line B= Slope of the measures leakage rate line ti= Specific time chosen 6.7

l 6.3 CILRT PROGRAM - PC COMPUTER (CONT)

Confidence limits are then determined for each estimated leakage rate value based on a confidence coefficient of 95%. This will ensure that the probability that the value of the estimated leakage falls within the true value of estimated leakage 95% of the time. The confidence limit is calculated using a Students T Distribution. The sum of the 95% confidence limit and estimated leakage is equal to the Upper Confidence Limit (UCL) .

The output from the program will then print out the time, mass measured leakage, estimated leakage, confidence limit and the Upper Confidence Limit for each data set.

The Type A test was satisfactorily completed after 32 hours3.703704e-4 days 0.00889 hours 5.291005e-5 weeks 1.2176e-5 months at 1300 hours0.015 days 0.361 hours 0.00215 weeks 4.9465e-4 months on November 20, 1986. Total time i

method was used to analyze the data to ensure that containment integrity met the requirements of 10 CFR 50 Appendix J. Figures 7.1 and 7.'o show the trends of containment mass and UCL leakage during the Type A test. Attachment 7.6 lists the final Type A test results with the various penalties being added to the results.

' Attachment 7.1 and 7.2 list the Total Time Type A test i results for instantaneous and ten minute averaged data from the plant process computer (P250). Prior to the

("' start of the Type A test, the NRC inspector stated that it was his interpretation that Paragraph III.A.3.(c) of 10 CFR 50 Appendix J called for instantaneous raw data to be used in the leakage rate calculations. During previous Type A tests, ten minute averaged data was used in the analysis. The program would scan raw data for a ten minute time period and then at the end of the ten minute time period would average these values and then print out a ten minute averaged value. These ten minute averaged values were then input into the ILRT program.

. The plant process computer (P250) ILRT program was modified such that the instantaneous values of time, containment pressure, dewpoint temperature and 7.1 4

(J 7.1 TYPE A TEST (CONT) containment temperature were printed out along with the average values. During the performance of the Type A test, both instantaneous and average data were used to calculate Type A test results for comparison purposes.

A concern was raised by the NRC inspector about the integrity of the data used to calculate the Type A test results. The nature of the P250 computer program is such that the raw data used to calculate instantaneous values is not available for review. The values are internally stored on a disk in the computer and cannot be retrieved. The NRC inspector wished to verify that the P250 program was applying the weight factors properly in its calculations, but since the raw data was not available, he was unable to do this. The raw s data was printed out on the P250 computer using its

_) trend block function every five minutes during the Type A test. The printing of these values, however, did not coincide with the printout of the instantaneous values from the P250 Type A program since both programs are not interrelated. It was due to this time difference that the values of raw data from the trend blocks could not be correlated to the printout of the instantaneous values.

To verify the integrity of the P250 program, hourly raw data was selected from the P250 trend blocks following the Type A test. The values were for the 32 hour3.703704e-4 days 0.00889 hours 5.291005e-5 weeks 1.2176e-5 months time 4

period that the Type A test was performed. These values are shown on Attachment 7.3. Using these values and the weight factors in Attachment 6.1, the average I

( 7.1 TYPE A TEST (CONT) containment pressure, dewpoint temperature and average temperature were calculated for each time segment.

These values were then input into the mainframe ILRT computer program to calculate the Total Time UCL leakage. Attachment 7.4 lists the results of these calculations. As can be seen by comparing the UCL leakage results of Attachment 7.1 and 7.4, the final raw data Total Time test results were even less than the final instantaneous Total Time test results. This proves beyond a reasonable doubt that the P250 ILRT program is correctly applying the weight factors.

An additional item was brought up by the NRC inspector involving the lineup of valve penetrations during the Type A test. His concern is that all valves which are listed in Surry Technical Specifications Table 3.8 and

() are required to be Type C tested must be vented and drained otherwise a penalty must be taken and added to the final Type A test results.

Penetrations 24, 46, 50, 56A, 63, 64, 66-71 and 92 were

, noted by the inspector as not being properly vented and drained or having the required penalty added to the Type A test results. From this list, Penetrations 24, 50 and 92 were indeed not vented and drained but the required penalties were added to the final test results and Penetration 70 was blanked off during the Type A test and the required penalty was added to the final test results(See Attachment 7.6).

(._) 7.1 TYPE A TEST (CONT)

The remaining penetrations from the inspectors list were not vented and drained because these systems would be used during and after a design basis accident.

Surry Technical Specification 4.4.A specifies that Type A testing will be performed in accordance with 10CFR50 Appendix J. Paragraph III.A.1.(d) of Appendix J states that systems that are normally filled with water and operating under post-accident conditions need not ba vented, however their containment isolation valves must be Type C tested.

Attachment 7.7 lists the containment penetrations by number for Surry Unit Two and their status during the Type A test. It is Virginia Powers position that the penetrations listed on Attachment 7.7 and identified by a Status of (5) meet the criteria in the above

() paragraph. These penetrations would be operating following a design basis accident.

The penetrations shown on Attachment 7.8 list the As-Left Type C leakages for each penetration for which the NRC inspector contends was improperly lined up. If the leakage penalties from this attachment were added to the final Type A test results(See Attachment 7.6),

the total leakage would still be well below the acceptable limit of .075 wt%/ day.

7.2 SUPERIMPOSED VERIFICATION TEST The supplemental verification test was satisfactorily performed using Attachment 7.17 of Reference 1.3.

Figure 7.3 shows a plot of leakage versus time for the

( 7.4

i I

() 7.2 SUPERIMPOSED VERIFICATION TEST (CONT) verification test. Included on the plot are the upper and lower limits for the verification test results.

The equation used to ensure that the verification test was acceptable was:

( Lam + Lo . 25La) < Lc < (Lam + Lo + .25La)

Where: Lam = Type A calculated leakage Lo= Superimposed leakage rate on containment Lc= Leakage during verification test (computer)

La= Maximum allowable leakage Attachment 7.5 has a listing of the final computer printout results for the verification test.

Substituting actual test results, the above equation

() turns out to be:

(.029254 + .1 .025) < .122879 < (.029254 +.1 +.025)

.104254 < .122879 < .154254 As shown above, Lc easily falls within the limits of the equation.

8.0 LOCAL LEAK RATE TESTS Type B and C tests were performed on containment penetrations prior to the Type A test. The As-Found and As-Left test results for these penetrations are shown in Attachment 8.1. The attachment also gives a description of any repairs if they were performed.

Also included in the attachment are Type B and C test results for tests that were performed since the last CILRT in June 1985.

The As-Found leakage prior to repairs being performed for Type B and C tests totaled >1331.89 SCFH.

Repairs / replacements were initiated to reduce the As-Found leakage since that value exceeded the stations

.6 La value of 180 SCFH. A majority of the leakage can be attributed to five penetrations.

~

Three penetrations had valves which had leakages greater than 300 SCFH. Penetration 38, which is the containment sump drain line, had an As-Found leakage of greater than 300 SCFH for both the inside and outside containment trip valves (TV-DA-200A, B) . A corrective action plan was initiated a few years ago for this penetration as a result of continuing leakage problems with the penetration. The plan included increased testing whereby the penetration would be Type C tested at each cold shutdown. Also a design change was initiated to replace these valves with a better design.

The valves were replaced this outage with ball valves since it was determined that their design was more suitable for this application.

Penetration 46, which is thE- Loop Fill Header (FCV-2160), and Penetration 63(2-CS-24),

Containment Spray penetration each had a leakage of l greater than 300 SCFH. The loop fill header is pressurized on the Auxiliary Building side of the valve by the charging pumps which also act as the high head safety injection pumps during an accident. The Containment Spray valve, 2-CS-24, is a check valve inside containment with two motor operated valves (MOVs) outside containment. The As-Found leakage for the two MOVs was 0.0 SCFH, therefore the maximum leakage that could have passed through the penstration using the minimum pathway leakage criteria was 0.0 SCFH.

Penetration 28(TV-2204), which is on the Letdown line, is a trip valve located outside contpinment. The As-Found leakage for this valve was 169.34 SCFH.

Inside containment on this penetration is three hand control valves (HCVs) in parallel which had an As-Found leakage of 18.66 SCFH. Therefore if the minimum pathway criteria is used, the maximum leakage through the penetration would be 18.66 SCFH.

Penetration 71, which is the Recirculation Spray line, had an As-Found leakage of 89 SCFH for outside containment MOV-RS-256A. This high leakage is attributed to the expansion joint inside containment which had holes in it. When the makeup Type C test was 8.2 a

The results of an As-Left test of the MOV after repairs to the expansion joint were 6.9 SCFH.

The As-Left leakage for Type B and C penetrations following repairs / replacements was 88.82 SCFH(.3 La).

l 9.0 AS-FOUND TYPE A TEST ANALYSIS An As-Found analysis has been performed on the Type A test to determine the leakage savings. The purpose is to try and determine what the actual Type A test leakage rate would be if the Type A test had been performed at the beginning of the outage prior to Type B and C testing.

The As-Found analysis is performed using the following criteria:

1) The leakage savings was calculated for each l

'. penetration that was repaired and/or I

replaced.

2) Minimum pathway leakage is the lowest leakage of the inside or outside valve grouping for the penetration in question.

3) If there were no repairs or replacements, a zero leakage savings is assessed to the penetration.

i 4) If the post-repair minimum leakage is greater

) than pre-repair minimum pathway leakage, a

, leakage savings of zero is assigned to the l penetration.

i

5) The leakage savings is the difference between j the pre-repair minimum pathway and post-repair minimum pathway leakages.

6) The not leakage savings (wt%/ day) is added to l the final Type A test results.

I 9.1 l

i 1

' 9.0 AS-FOUND TYPE A TEST ANALYSIS (CONT)

Two different As-Found analysis were performed as suggested by the NRC inspector witnessing the test. In i.

j the first analysis, which is shown on Attachment 9.1,

containment isolation valves that were repaired / replaced are listed in the table. A leakage savings value of zero SCFH has been assigned to the

penetrations that the station has deemed non-liable.

) These penetrations are identified by a notation next to the Leakage Savings value with a justification on the accompanying page of the Attachment.

These justifications take credit for the fact that these safety-related systems are operating during post-accident conditions. Their operation prevents outleakage when the containment isolation valves are r~g leaking. In addition, surveillance tests are performed l on these systems to ensure that any external leakage from packing, flanges and other mechanical joints is i less than the allowable limit specified in Technical Specifications. Taking the AS-FOUND analysis into account, the final Type A test leakage would be .0728 wt%/ day. This value is less than the acceptable limit i of .075 wt%/ day, therefore Surry Unit 2 ILRT is I

considered a successful test.

The second analysis, which is on Attachment 9.2, lists containment isolation valves that were j repaired / replaced without taking into account the operation of the safety-related penetrations.

AS-FOUND TYPE A TEST ANALYSIS NOTES:

1) This line is from the charging pump header and is used to supply the loops. The charging pumps are used as the high head safety injection pumps. The chemical and volume control system valves, piping, and components have been designed to permit essentially zero leakage. Periodic surveillance is performed to verify leakage is within specifications.

Reference Surry UFSAR Section 6.2.3.10, External Recirculation Loop Leakage.

2) The containment sump trip valves, TV-DA-200A and B, were replaced this outage with valves whose design is better than the existing valves. The old valves were globe valves while the new valves are ball type valves with a hard seating surface.

The replacement of these valves is the final step of the stations corrective action plan which was initiated in 1984 to improve the reliability of the penetration. The plan

/ consisted of increased Type C testing whereby the valves would be tested at each cold shutdown condition and valves that had excessive leakage would be repaired. At the same time, an analysis was initiated to find a more reliable valve design. This analysis resulted in the ball type valve being selected.

The As-Found leakage for both TV-DA-200A and B exceeded 300 SCFH, which is the stations La value. It has been determined that this high leakage value is attributed to the decontamination of the containment prior to the testing of the valves. A significant amount of debris is washed into the sump during the decontamination effort and is then pumped out of the containment sump through TV-DA-200A and B. The containment sump valves are both open when the sump pumps are operating, but close when the sump pumps shut off. When the valves close, debris in the line gets caught in the valve causing damage to their seating surface.

This damage to the seating surdace is why both valves exhibited high leakage during the As-Found Type C tests.

() Page 2 of 4

q

'd NOTESfCONT):

A look at the Type C leakage history for these valves since the last refueling in 1985 shows that neither valve had an As-Found leakage above 50 SCFH. During these tests which were performed at cold shutdown, the extensive decontamination that is performed during refueling is not performed.

In an effort to further improve the reliability of this penetration, the opening and closing sequence of the sump valves has been modified.

Now when the containment sump pump shuts off, the isolation valves will remain open. This reduces the chances of debris getting caught in the valves seating surface and reduces the amount of cycling that occurs during power operations. The valves still retain their safety related function by receiving a close signal on a Safety Injection.

3) This line is from the charging pump header and is used to fill the loops. The charging pumps are used as the high head safety injection pumps. The chemical and volume control system

(,_' valves, piping, and components have been x

designed to permit essentially zero leakage.

Periodic surveillance is performed to verify leakage is within specifications. Reference Surry UFSAR Section 6.2.3.10, External l Recirculation Loop Leakage. l

4) This line is from the low head safety injection pump header and is used to supply the loops. I The safety injection system valves, piping, and l components have been designed to permit l essentially zero leakage. Periodic surveillance is performed to verify leakage is within specification. Reference Surry UFSAR Section 6.2.3.10, External Recirculation Loop Leakage.

5) This line is from the containment spray pump discharge. The containment spray system is designed to operate after the DBA LOCA to depressurize the containment to subatmospheric pressure. The containment spray system valves, piping, and components have been designed to permit essentially zero leakage. Periodic surveillance is performed to verify leakage to within specifications.

operate after the DBA LOCA to depressurize the containment to subatmospheric pressure. The sumps' lines are filled with water and would i

prevent outleakage either through operation and/or water seal. Periodic surveillance is performed to verify leakage is within specifications. Reference Surry UFSAR Section 6.3.1.4.

This is the sump suction line to the low head 7) safety injection pump. The sumps' lines are filled with water and would prevent outleakage either through operation and/or a water seal.
