4 ATTACHMENT Response to Generic Letter 89-13 Service Water System Problems Affectina Safety-Related Equipment Recommended Action To Be Taken by Addressees:
t The NRC requests-that licensees and applicants perform the following or equally effective actions to ensure that their service water systems are in compliance and will be maintained in compliance with 10 CFR Part 50, Appendix A, General Design Criteria 44, 45, and 46 and Appendix B,Section XI.
If.a licensee or applicant chooses a
- course of action different from the recommendations below, the
- licensee or applicant should document and retain in appropriate plant records a justification that the heat removal requirements of the service water system are satisfied by use of the alternative program.
Resoonse:
The Beaver Valley Power Station Unit 1 and 2 service water systems are in compliance and will be maintained in compliance with 10 CFR 50, Appendix A, General Design Criteria 44, 45 and 46 and Appendix B,Section XI as discussed in the BVPS Unit 1 and 2 Final Safety Analysis Reports and associated Safety Evaluation Reports issued by the NRC.
Assurance that the service water systems meet the minimum requirements of the above is provided in the responses to the following recommendations.
Action I.
For open-cycle service water systems, implement and maintain an ongoing program of surveillance and control techniques to significantly reduce the incidence of flow blockage problems as a-result of biofouling.
A program acceptable to the NRC is described in " Recommended Program to Resolve Generic Issue 51"_(Enclosure 1).
It should be noted that Enclosure 1 is provided as guidance for an acceptable program.
An equally effective program to preclude biofouling would also be acceptable.
Initial activities should be completed before plant startup following the first refueling outage
- beginning 9 months or more after the date of this letter.
All activities should be documented and all relevant documentation should be retained in appropriate plant records.

Recommended Procram to Resolve Generic Issue 51 This enclosure describes a program acceptable to the NRC for meeting the objectives of the requested Action I in the proposed generic letter.
Both Action I and this enclosure are based upon the recommendations described in " Technical Findings Document for Generic Issue 51:
Improving the Reliability of Open-cycle Service-Water Systems," NUREG/CR-5210, August 1988, and "Value/ Impact Analysis for Generic Issue 51:
Improving-the Reliability of Open-Cycle Service-Water Syntems," NUREG/CR-5234, February 1989.
The NRC has concluded that Generic Issue 51 will be resolved when licensees and applicants implement either the recommended surveillance and control program addressed in this enclosure or an equally effective alternative course of action to satisfy the heat removal requirements of the service water-system.
Water Source Surveillance Control Tyne Techniaues Techniaues Marinc or' Estuarine A
B and C (brackish) or Freshwater with clams Freshwater without clams A and D B and C
Response
Beaver Valley Power Station has a freshwater (river) source and has identified clams as being in the water source.
Therefore, Surveillance Technique A and Control Techniques B and C are addressed as follows:
Surveillance Techniaue A:
The intake structure should be visually inspected, once per refueling cycle, for macroscopic biological fouling organisms (for example, blue mussels at marine plants, American oysters at estuarine plants, and Asiatic clams at freshwater plants), sediment, and corrosion.
Inspections should be performed either by scuba divers or by dewatering the intake structure or by other comparable methods.
Any fouling accumulations should be removed.
- w t
ATTACHMENT 1
Response to Generic Letter 89-13 ResDonse A:
[
The intake structure is inspected twice per year (spring and fall) for Asiatic clams.and sediment.
Inspections are performed either by divers, or by dewatering.
Fouling accumulations (clams, sediment) are' removed.
Control Technicue B:
The service-water system should be continuously (for example, during
{
spawning) chlorinated (or equally effectively treated with another biocide) whenever the potential for a macroscopic biological fouling species exists (for example, blue mussels at marine plants, American oysters-at estuarine plants, and Asiatic clams at freshwater plants).
Chlorination or equally effective treatment is included for
~
freshwater plants without clams because it can help prevent microbiologically influenced corrosion.
However, the chlorination (or equally effective) treatment need not be as stringent for plants where the-potential for macroscopic biological fouling species does not exist compared to those plants where it does.
Precautions should be taken to obey Federal, State, and local environmental regulations regarding the use of biocides.
Response B:
The service water' system is presently chlorinated 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> per day in compliance with the BVPS NPDES Permit.
At the present time, this program is considered an equally effective treatment to continuous chlorination.
However, the program is being monitored and, if required, appropriate changes will be made to assure that the performance of the service water system will not be reduced.
Control Techniaue C:
Redundant and infrequently used cooling loops should be flushed and flow tested periodically at the maximum design flow to ensure that they are not fouled or clogged.
Other components in the service water system should be tested on,a regular schedule to ensure that they are not fouled or clogged.
Service water cooling loops should be filled with chlorinated or equivalently treated water before layup.
Systems that use raw service water as a source, such as some
. fire protection systems, should also be chlorinated or equally effectively treated.before layup to help prevent microbiologically influenced corrosion.
Precautions should be taken to obey Federal, 4
State, and local environmental regulations regarding the use of blocides.
V Paga 4 ATTACHMENT Response to Generic Letter 89-13 Resnonse C :
Redundant and infrequently used cooling loops are presently flushed and flow tested periodically at the design flow rate.
Procedures will be revised and testing scheduled on a regular basis to ensure that the other components in the service water system are not fouled or clogged.
Service water cooling loops will either be drained (dry-layup) or treated with chlorine or equivalently treated water before layup (wet-layup).
The BVPS Fire Protection System (FPS) uses raw service water as a source.
We are evaluating the addition of chlorine or equally effectively treated water before layup.
This evaluation will consider the materials compatibility of the biocide, effects on equipment protected by water suppression systems and HPDES restrictions.
The above activities described in the responses to Action I will be completed before plant startup following the next refueling outage for each unit.
All activities will be documented and all relevant documentation will be retained in appropriate plant records.
Action II Conduct a test program to verify the heat transfer capability of all safety-related heat exchangers cooled by service water.
The total test program should consist of an initial test program and a periodic rotest program.
Both the initial test program and the periodic retest program should include heat exchangers connected to or cooled by one or more open-cycle systems as defined above.
operating experience and studies indicate that closed-cycle service water systems, such as component cooling water systems, have the potential for significant fouling as a consequence of aging-related in-leakage and erosion or corrosion.
The need for testing of closed-cycle system heat exchangers has not been considered necessary because of the assumed high quality of existing chemistry control programs.
If the adequacy of these chemistry control programs cannot be confirmed over the total operating history of the plant or if during the conduct of the total testing program any unexplained downward trend in heat exchanger performance is identified that cannot be remedied by maintenance of an open-cycle system, it may be necessary to selectively extend the test program and the routine inspection and I
maintenance program addressed in Action III, below, to the attached closed-cycle systems.

t Pr.g3 5 ATTACHMENT Response to Generic Letter 89-13 A program acceptable to the NRC for heat exchanger testing is described in " Program for Testing Heat Transfer Capability" (Enclosure 2).
It should be noted that Enclosure 2 is provided as 4
guidance for an acceptable program.
An equally effective program to ensure satisfaction of the heat removal requirements of the service water system would also be acceptable.
Testing should be done with necessary and sufficient instrumentation, though the instrumentation need not be permanently installed.
The relevant temperatures should be verified to be within design limits, i
If similar or equivalent tests have not been performed during the past year, the initial tests should be completed before plant startup following the first refueling outage beginning 9 months or more after the date of this letter, j
As a part of the initial test program, a licensee or applicant may I
decide to take corrective action before testing.
Tests should be performed for the heat exchangers after the corrective actions are-taken to establish baseline data for future monitoring of heat exchanger performance.
In the periodic retest program, a licensee or applicant should determine after three tests the best frequency for testing to provide assurance that the equipment will perform the intended safety functions during the intervals between tests.
Therefore, in the periodic retest program, to assist that determination, tests should be performed for the heat exchangers before any corrective actions are taken.
As in the initial test program, tests should be repeated after any corrective actions are j
taken to establish baseline data for future monitoring of heat exchanger performance.
An example of an alternative action that would be acceptable to the NRC is frequent regular maintenance of a heat exchanger in lieu or testing for degraded performance of the heat exchanger.
This alternative might apply to small heat exchangers, such as lube oil coolers or pump bearing coolers or readily serviceable heat exchangers located in low radiation areas of the facility.
In implementing the continuing program for periodic retesting of safety-related heat exchangers cooled by service water in open-cycle systems, the initial frequency of testing should be at least once cach fuel cycle, but after three tests, licensees and applicants should determine the best frequency for testing to provide assurance that the equipment will perform the intended safety functions during the intervals between tests and meet the requirements of GDC 44, 45, and 46.
The minimum final testing frequency should be once every 5 years.
A summary of the program should be documented, including the schedule for tests, and all relevant documentation should be retained in appropriate plant records.

This program will include an initial test program and a periodic retest program for the heat exchangers cooled by the open-cycle service water system.
The need for testing the closed-cycle system heat exchangers is not considered necessary at the present time because of the high quality of existing chemistry control programs.
However, if during the conduct of the total testing program, a downward trend in heat exchanger performance is identified that cannot be remedied by maintenance of the open-cycle system, the test program and inspection and maintenance program will be selectively extended to the closed-cycle system as discussed in the Action III response.
Testing will be performed with both portable and permanently installed instrumentation.
This instrumentation will be sufficient (within the limits of piping size, and equipment location) to ensure that test results are accurate and are capable of being repeated.
The relevant temperatures will be verified to be within design limits.
If similar or equivalent tests have not been performed within the past fuel cycle, the initial tests will be completed before plant c'ertup following that unit's next outage.
If necessar, ce rective action will be taken before testing in order
.ll establish baseline data for future monitoring of that the tesa w
heat exchanger performance.
In the periodic retest program, three tests, at least one each fuel cycle, will be used to establish the best frequency for testing.
This frequency will provide assurance that the equipment will perform its intended safety function during the interval between tests, and meet the requirements of GDC 44, 45 and 46.
The minimum final testing frequency will be once every 5 years or on a comparable time period tied to refueling outage cycles.
To assist in this determination, tests will be performed, where possible, before any corrective action is taken.
Tests will then be repeated after corrective actions to reestablish baseline data for future monitoring of the heat exchanger performance.
A summary of the program will be documented and will be retained in appropriate plant records.
Alternatively, to the above test program, regular maintenance of selected heat exchangers in lieu of testing for degraded performance is planned for selected heat exchangers.
The attached Tables 1 and 2 delineate the BVPS Units 1 and 2 heat exchangers and the type of tests and/or maintenance that are scheduled to be performed.

ATTACHMENT Response to Generic Letter 89-13 ENCLOSURE 2 PROGRAM FOR TESTING HEAT TRANSFER CAPABILITY This enclosure describes a program acceptable to the NPC for meeting the objectives of the requested Action YI in the proposed generic letter.
Both Action II and this enclosure are based in part on
" Operating Experience Feedback Report - Service Water System Failures and Degradations," NUREG-1275, Volume 3, November 1988 and " Technical Findings Document for Generic Issue 51 Improving the Reliability of Open Cycle Service Water Systems," NUREG/CR-5210, August 1988.
This enclosure reflects continuing operational problema, inspection reports, and industry standards (" Operation and Maintenance of Nuclear Power Plants," ASME/ ANSI OM-1987, Part 2.)
The NRC requests licensees and applicants to implement either the steps addressed in this enclosure or an equally effective alternative course of action to satisfy the heat removal requirements of the service water system.
Both the initial test program and the periodic retest program should include all safety-related heat exchangers connected to or cooled by one or more open-cycle service water systems.
A closed-cycle system is defined as a part of the service water system that is not subject to significant sources of contamination, one in wnich water chemistry is controlled, and one in which heat is not directly rejected to a heat sink.
(The scope of closed cooling water systems is discussed in the industrial standard, " Operation and Maintenance of Nuclear Power Plants," ASME/ ANSI OM-1987, Part 2.)
If during the conduct of the total testing program any unexplained downward trend in heat exchanger performance is identified that cannot be remedied by maintenance of an open-cycle system, it may be necessary to selectively extend the test program to the attached closed-cycle system.
Testing should be done with necessary and sufficient instrumentation, though the instrumentation need not be permanently installed.
As a part of the initial tests program, a licensee or applicant may decide to take corrective action before testing.
Tests should be performed for the heat exchangers after the corrective actions are taken to estabidsh baseline data for future monitoring of heat exchanger performar.ce.
In the periodic rotest program, a licensee or applicant should determine after three tests the best frequency for testing to provide assurance that the equipment will perform the intended safety functions during the intervals between tests.
Therefore, in the periodic retest program, to assist that determination, tests should be repeated after any corrective actions are taken to eetablish baseline data for future monitoring of heat exchanger performance.

For All Heat Exchangers Monitor and record cooling water flow and inlet and outlet temperatures for all affected heat exchangers during the modes of operation in which cooling water is flowing through the heat exchanger.
For each measurement, verify that the cooling water temperatures and flows are within design limits for the conditions of the measurement.
The test results from periodic testing should be trended to ensure that flow blocPage or excessive fouling accumulation does not exist.
Response
Cooling water flow, inlet and outlet pressures and temperatures, where possible, will be monitored and recorded for all affected heat exchangers in the test program.
These meanurements will be made during modes of operation in which cooling water is flowing through the heat exchanger.
The above cooling water flows, pressures and temperatures will be verified to be within the design limits for the i
conditions of the measurement.
The test results will be trended to i
ensure that flow blockage or excessive fouling does not exist.
II. In addition to the considerations for all heat exchangers in Item I, for water-to-water heat exchangers A.
Perform functional testing with the heat exchanger operating, if practical, at its design heat removal rate to verify its capabilities.
Temperature and flow compensation should be made in the calculations to adjust the results to the design conditions.
Trend the results, as explained above, to monitor degradation.
An example of this type of heat exchanger would be that used to cool a diesel generator.
Engine jacket water flow and temperature and service water flow and temparature could be monitored and trended during the diesel generator surveillance testing.

- Response to Generic Letter 89-13 Action III.
Ensure by establishing a routine inspection and maintenance progran for open-cycle service water system piping and components that corrosion, erosion, protective coating failure, silting, and biofouling cannot degrade the performance of the safety-related systems supplied by service water.
The maintenance program should have at least the following purposes:
A.
To remove excessive accumulations of biofouling agents, corrosion products, and silt; B.
To repair defective protective coatings and corroded service watersystempipingandcomponentsthatcouldadverselyaffect performance of the.r intended safety functions.
This program should be established before plant startup following the first refueling outage beginning 9 months after the date of this letter.
A description of the program and the results of these maintenance inspections should be documented.
All relevant documentation should be retained in appropriate plant records.
Response
A routine inspection and maintenance program for open-cycle service water system piping and components is in effect at BVPS.
This program is being reviewed to ensure that corrosion, erosion,
. protective coating failure, silting and biofouling will not degrade the performance of the safety-related systems supplied by service water.
The maintenance program contains, at the least, the following:
A.
Removal of excessive accumulations of biofouling agents, corrosion products and silt.
B.
Repair of defective protective coatings (if any) and corroded piping and components that could adversely affect performance.
These programs for Action III will be reviewed and revised as required prior to plant startup following the next refueling outage.
A description of the programs and results of inspections will be documented and will be retained in appropriate plant records.
. Action IV.
Confirm that the service water system will perform its intended function in accordance with the licensing basis for the plant.
Reconstitution of the design basis of the system is not intended.
This confirmation should include a review of the ability to perform required-safety functions in the event of failure of a single active component.

W
\\
Pcg3 12 ATTACHMENT Response to Generic Letter 89-13 the appropriate licensing basis documentation, this confirmation should include recent (within the past 2 years) system walkdown inspections.
This confirmation should be completed before plant startup following the first refueling outage beginning 9 months or more after the date of this letter.
Results should be documented and retained in appropriate plant records.
t
Response
Confirmation that the service water system will perform its intended function in accordance with the licensing basis (FSAR, Tech Specs, etc.) will be performed by single failure analyses, system walkdowns or design basis reviews.
To ensure that the as-built system is in accordance with appropriate documentation, system walkdowns were performed for BVPS-1 in 1989 and for BVPS-2 during construction turnover to operations in 1987.
These walkdowns satisfactorily address the 2-year system walkdown inspections.
Confirmation of the design basis reviews will be completed before startup following each unit's next refueling outage.
Results will be documented and will be retained in appropriate plant records.
l Action V Confirm that maintenance practices, operating and emergency procedures, and training that involve the service water system are adequate to ensure that safety-related equipment cooled by the service water system will function as intended and that operators of this equipment will perform effectively.
This confirmation should include recent (within the past 2 years) reviews of practices, procedures, and training modules.
The intent of this action is to reduce human errors in the operation, repair, and maintenance of the service water system.
This confirmation should be completed before plant startup following the first refueling outage beginning 9 months l
or more after the date of this letter.
Results should be documented and retained in appropriate plant records.
Resnonse Maintenance practices, operating and emergency procedures and training modules that involve the service water system are i
periodically reviewed and updated as required to ensure that i
l safety-related equipment cooled by the service water system will function as intended and that operators of this equipment will perform effectively.
Since reviews of practices, procedures and training modules are already in effect, additional confirmation is not required.
These reviews already take into consideration the reduction of human error (training module revisions) and its effect on the operation, repair and maintenance of the service water system.
In addition, Safety System Functional Evaluations and Probabilistic Risk Assessments are being performed to further ensure that equipment will function as intended.
These reviews are retained l
in appropriate plant records.
