SHNPP FSAR Page 1 of 16 TMI APPENDIX I. Introduction This Appendix describes the compliance by the Shearon Harris Nuclear Power Plant with NUREG-0737, "Clarification of TMI Action Plan Requirements" issued by the NRC on October 31, 1980. Item numbers contained within this Appendix correspond to the item numbers of NUREG-0737. The information contained within this Appendix is in addition to and beyond the information contained in other sections of this FSAR. Where information between this Appendix and other sections of the FSAR is in conflict, this Appendix takes precedence.

This Appendix only addresses compliance with NUREG-0737 requirements. This, however, is only one portion of Carolina Power & Light Company's response to the accident at Three Mile Island Unit 2. Immediately following the accident, CP&L commissioned a Corporate Investigative Team (CIT) to review the design and operation of its operating plants and the SHNPP with regard to the accident and to make recommendations to management concerning modifications and improvements in design, operations, and training. In addition to the NRC mandated requirements, management has reviewed those recommendations made by CIT and they are being evaluated for incorporation into the SHNPP design, planned operations, and training. Additionally, CP&L has been very active in industry groups formed to respond to the accident including two NSSS owners' groups. The information obtained from these groups is continuously provided to those responsible for the design of the plant, the planned operations of the plant, and the training of plant personnel. Finally, as CP&L has implemented plant modifications and modified operations and training at its operating plants in response to the TMI accident, the experience and information obtained has been and is continuing to be provided to the SHNPP organization for incorporation into the design and operation of SHNPP. Carolina Power & Light's response to the accident at TMI is an ongoing process which will continue to implement lessons learned from the accident in the future as they are obtained.

II. Response to NUREG-0737, "Clarification of TMI Action Plan Requirements" Carolina Power & Light Company's response to NUREG-0737, "Clarification of TMI Action Plan Requirements" is contained in the following paragraphs.

SHIFT TECHNICAL ADVISOR (I.A.1.1)

SHNPP complies with the requirements of this item. The Shift Engineer fulfills the requirements of the Shift Technical Advisor.

SHIFT SUPERVISOR RESPONSIBILITIES (I.A.1.2)

SHNPP complies with the requirements of this item. The Superintendent -Shift Operations fills the position described by NRC as Shift Supervisor. The required directions, descriptions, training programs, and procedures will be in place prior to receiving an Operating License.

SHIFT MANNING (I.A.1.3)

SHNPP will comply with the requirements of this item. The minimum shift crew composition in Section 6 of the Technical Specifications will be revised to be consistent with the interim guidelines. Administrative procedures establishing overtime restrictions consistent with the guidance of Generic Letter 82-02 will be implemented prior to receipt of an Operating License.

SHNPP FSAR Page 2 of 16 TMI APPENDIX IMMEDIATE UPGRADING OF REACTOR OPERATOR AND SENIOR REACTOR OPERATOR TRAINING AND QUALIFICATIONS (ITEM I.A.2.1)

The requirement for an applicant for a senior reactor operator license to have been a licensed reactor operator for one year does not apply to cold license candidates. As noted in the NRR letter (3/28/80), pre-critical applicants will be required to meet unique qualifications designated to accommodate the fact that their facility has not yet been in operation. SHNPP will fully comply with the requirements of this item after cold licensing is complete.

ADMINISTRATION OF TRAINING PROGRAMS (ITEM I.A.2.3)

SHNPP complies with the requirements of this item (see FSAR Sections 1.8 and 13.2).

REVISE SCOPE AND CRITERIA FOR LICENSING EXAMINATIONS - SIMULATOR EXAMS (ITEM 3) (ITEM I.A.3.1)

SHNPP will comply with the requirements of this item by using the Harris simulator to give the simulator examinations. For cold license candidates the simulator operating examination will be given depending on installation and availability of the plant referenced simulator.

EVALUATION OF ORGANIZATION AND MANAGEMENT (I.B.1.2)

The Onsite Independent Safety Engineering Group (ISEG) functions are no longer performed by a dedicated group at the site. The functions of the dedicated ISEG are no longer required to be maintained, as these functions are redundant to established functions and processes performed by existing organizations. These functions are described in FSAR section 17.3.4.1.4.

SHORT-TERM ACCIDENT AND PROCEDURE REVIEW (I.C.1)

The Westinghouse Owners' Group, of which CP&L is a member, has developed and submitted to the NRC the required Emergency Response Procedure Guidelines. Following NRC approval of these guidelines, CP&L will make all necessary procedure revisions at SHNPP prior to fuel loading.

SHIFT AND RELIEF TURNOVER PROCEDURES (I.C.2)

SHNPP complies with the requirements of this item (see Section 13.5.1.3a(6)).

SHIFT SUPERVISOR RESPONSIBILITY (I.C.3)

SHNPP complies with the requirements of this item. The Superintendent -Shift Operations fills the position described by NRC as Shift Supervisor. The required directions, descriptions, training programs, and procedures will be in place prior to receiving an Operating License.

CONTROL ROOM ACCESS (I.C.4)

SHNPP complies with the requirement of this item (see Section 13.5.1.3a(7)).

SHNPP FSAR Page 3 of 16 TMI APPENDIX FEEDBACK OF OPERATING EXPERIENCE (I.C.5)

An organization for the review and feedback of operational experience is in existence in the CP&L structure. Formal procedures for the dissemination and review of operational experience feedback information by the plant and corporate staffs are in place.

VERIFY CORRECT PERFORMANCE OF OPERATING ACTIVITIES (I.C.6)

SHNPP will be in compliance with the guidelines of I.C.6 before the issuance of an Operating License. Plant procedures will be in effect which specify the control of plant systems and the requirements to remove or return systems to service. Appropriate requirements for the use of a second qualified person will be included along with criteria for what constitutes a "qualified" person.

NSSS VENDOR REVIEW OF PROCEDURES (I.C.7)

SHNPP will comply with this item and commit to a review of low power and power ascension procedures related to the NSSS by Westinghouse personnel as discussed in NUREG-0737.

These reviews will be performed by onsite Westinghouse personnel if they have the necessary expertise, otherwise, they will be reviewed by appropriate offsite Westinghouse personnel.

CP&L considers this course of action to meet the intent of NUREG-0737.

The requirement for NSSS vendor review of Emergency Operating Procedures (EOP) is satisfied by Westinghouse's participation in the development of Westinghouse Owners' Group Emergency Response Guidelines (ERG). SHNPP EOP are based on Revision 1 of the ERG with only minor plant specific modifications. Due to the extensive Westinghouse review of the ERG, CP&L does not intend to submit the SHNPP EOP to Westinghouse for additional review.

PILOT MONITORING OF SELECTED EMERGENCY PROCEDURES FOR NTOLs (I.C.8)

CP&L will carefully consider the feedback developed from this NRC review of procedures and will incorporate any new requirements or other findings which appear appropriate to the SHNPP Emergency Procedures.

CONTROL-ROOM DESIGN REVIEWS (I.D.1)

A Control Room design review for SHNPP was conducted by the Essex Corporation from April 1980 to January 1981.

As a result of this review, the Main Control Board was redesigned and equipment relocated.

Further, for design features which could not be evaluated or measured due to the then present stage of construction, Essex developed human engineering specifications. These specifications will be used as applicable to assure a well-engineered Control Room from the human factors engineering point of view.

CP&L considers this item complete.

PLANT SAFETY PARAMETER DISPLAY CONSOLE (I.D.2)

At SHNPP a top level display derived from plant parameters and indicative of the plant safety status will be displayed.

SHNPP FSAR Page 4 of 16 TMI APPENDIX The display and data format (presentation) will be in conformance with human-factors criteria.

By using redundant instrument comparisons, checks for reasonability limits and normal operational limits, inferential checks to compare with other variables that are functionally related and by checking for detectable signal failures, all scanned variables will be quality tagged to indicate out-of-scan, open, out-of-sensor range, questionable status or substitute (entered) value.

By using reliable components, system design and redundant direct instrument channels on the main control board, essential indications will be available during normal and abnormal plant operating conditions.

Instrument channels, scan rates, processing methods and data displays will be chosen or designed to display pertinent information during both steady state and transient plant operation.

Signal processing (transforms), will be available along with sufficient display processing to allow all information to be displayed in the most suitable form. Instantaneous values, averages, summations, rates, and trends of any parameter or group of parameters may be chosen and displayed. Also, alarms and automatic display can be initiated based on instantaneous values or rates crossing setpoints or limits.

Interfaces between the SPDS system and safety systems will have isolation that meets all the required category IE requirements. The isolation will ensure the integrity of the safety systems.

Further, where the SPDS interfaces with non-safety systems, the isolation and the SPDS design will be such that the SPDS is not degraded beyond the loss of signals from the failed non-safety system, i.e., the degradation will be limited to loss of information from the failed non-safety system.

Qualification programs will be included in the specification, design, implementation, test, installation and operation to demonstrate the SPDS's conformance to the design criteria.

Staffing No one other than the normal control room operating staff will be required for operations of the SPDS.

Display Consideration Instrument channels, scan rates, procession rates and display devices will be chosen to give information response equivalent to conventional dedicated control room instruments. The system will respond to transient and accident sequences.

Both the top level display and the supplemental displays will be designed to independently or jointly display the status of the plant. The displays will at all times be sufficient to display plant status to the control room staff.

Information will be displayed on a single primary display in a form that meets human-factors guidelines. The format(s) will be suitable for all plant operating modes.

Process signals available to the system (SPDS, TSC or EOF) will be available for display on secondary display(s) in a number of designated formats. The secondary information will be

SHNPP FSAR Page 5 of 16 TMI APPENDIX readily available to the RO, SROs, or STA to aid in the analysis of any event, to assist in terminating a possible event or to assist in mitigating the consequences of an actual event.

The basis for selecting the minimum data set for the primary display will be documented in the final system design.

The SPDS will access all available signals and will display information related to:

Reactivity control Reactor core cooling and heat removal from primary steam Reactor coolant system integrity Radioactivity control Containment integrity Secondary displays will be available and system design will provide for automatic (event initiated) or manual (demand) control of the initiation or format of displays.

The system shall be designed to be modular in both hardware and software to allow for future modifications or additions. The system will be designed to be field expandable and testable to minimize any impact on system operation or integrity resulting from required modification or additions.

Design Criteria Sensors, signal conditioners, and isolation devices shall be chosen from or designed to meet Class 1E requirements for all signals shared with or used by safety systems. The quality of all added devices (isolation, etc.) will be such that the quality of the signals to the SPDS will not be degraded.

Processing equipment, displays and related equipment will be high quality industrial grade equipment suitable for the application and the environment in which it will operate.

Controls, displays and related procedures will be designed to meet human-factors guidelines.

The system will be designed to function during and following an earthquake and still supply the essential data to the SPDS.

The function of the SPDS does not warrant seismic qualification because of the low probability of a seismic event concurrent with the need for the SPDS function, given the availability of seismically qualified displays for key safety parameters in the control room. Further, a separate additional concentrated display is not required as a backup for a nonseismic SPDS and is conceptually contrary to good human engineering practices.

Qualified indicators are available and with proper training of the operators, they are adequate for controlling the plant under all conditions.

The requirement to install separate additional seismic displays compounds the human factors problem and is also in conflict with sound operating practice which encourages that the operator use normal operating displays during accidents. This use of existing displays is most desirable

SHNPP FSAR Page 6 of 16 TMI APPENDIX since the operator will always get information to perform critical and normal operating functions from the same location. The SPDS, by definition is intended o concentrate a minimum set of plant parameters to aid the operator in the rapid detection of abnormal operating events.

However, it is reasonable to use the normal qualified displays as a backup for this purpose.

TRAINING DURING LOW -POWER TESTING (I.G.1)

SHNPP is in compliance with this item. Our commitment to training during special low power testing is made in section 13.2.1.1.2H of the FSAR, Amendment 23.

REACTOR COOLANT SYSTEM VENTS (II.B.1)

For information on the RCS vent system refer to FSAR Section 5.4.12.5.

PLANT SHIELDING (II.B.2)

SHNPP compliance with this item is outlined in the FSAR Sections 12.2.1.12, 12.3.2.16, and 3.11.

POST ACCIDENT SAMPLING (II.B.3)

SHNPP compliance with this item is outlined in FSAR Section 6.2.5 and 9.3.2.

TRAINING FOR MITIGATING CORE DAMAGE (ITEM 11.B.4)

SHNPP will comply with the requirements of this item.

PERFORMANCE TESTING OF BWR AND PWR RELIEF AND SAFETY VALVES (II.D.1)

Carolina Power & Light Company is a participant in EPRI's PWR Safety and Relief Valve Testing Program. Test results have been submitted to the NRC by EPRI. Carolina Power &

Light Company considers the program to be responsive to the requirements presented in NUREG-0578, Item 2.1.2, as clarified by NUREG-0660 and NUREG-0737, Item II.D.1.

Valves tested under the EPRI Program included actual valves (relief, safety, and block) from the SHNPP. Test conditions used were reflective of applicable operating/transient conditions of the SHNPP. Thus, these test results are directly applicable to SHNPP.

SHNPP will submit an analysis of the effect of as-built relief and safety valve discharge piping on valve operability by February 1984.

RELIEF AND SAFETY VALVE POSITION INDICATION (II.D.3)

The code safety relief valve positions will be directly derived from environmentally and seismically qualified reed type limit switches mounted on the valve top works and powered from a vital instrument bus. The position can be displayed on the Emergency Response Facility Information System (ERFIS) display located on the main control board. The ERFIS display will indicate the status as shut/not shut by graphic and/or English text displays. In addition, strap on resistance temperature detectors are provided upstream of the SRVs within the water section of each loop seal as a backup to indicate if there is valve seat leakage which is indicative of the

SHNPP FSAR Page 7 of 16 TMI APPENDIX valve not being fully shut. Both methods of detection are alarmed on the annunciator on the main control board.

The power operated relief valves utilize valve stem limit switches for position indication which is monitored by the use of indicative lights on their associated control modules. These limit switches are both seismically and environmentally qualified. The ERFIS display can indicate the status as open/not open by graphic or English text displays. In addition, a strap on resistance temperature detector is provided downstream in a common header as a back up to indicate valve seat leakage from any of the three PORV's. All methods of detection are alarmed on the annunciator on the control board.

AUXILIARY FEEDWATER SYSTEM EVALUATION (II.E.1.1)

The AFW System Safety Evaluation is addressed in FSAR Section 10.4.9.3.

AUXILIARY FEEDWATER SYSTEM AUTOMATIC INITIATION AND FLOW INDICATION (II.E.1.2)

SHNPP compliance with this item is described in FSAR Sections 7.2.2, 7.3.1, 7.3.2, and 7.5.

Compliance with IEEE-279-1971 is detailed in FSAR Section 7.3.2.2.

EMERGENCY POWER FOR PRESSURIZER HEATERS (II.E.3.1)

SHNPP compliance with this item is outlined in FSAR Section 8.3.1.2.35.

DEDICATED HYDROGEN PENETRATIONS (II.E.4.1)

This item does not apply to SHNPP since qualified redundant in-containment thermal recombiners are provided. Refer to FSAR Section 6.2.5.

CONTAINMENT ISOLATION DEPENDABILITY (II.E.4.2)

SHNPP compliance with this item is outlined in FSAR Section 6.2.4, 7.3.1.1, and 7.3.1.3.2.

ACCIDENT MONITORING INSTRUMENTATION (II.F.1)

Necessary procedures required for this item will be prepared prior to fuel load at SHNPP.

SHNPP compliance with the parts of this item concerning the Noble Gas Monitor, the Iodine and Particulate Monitor, and the Containment High Range Radiation Monitor is outlined in FSAR Sections 11.5.2 and 12.3.4 SHNPP compliance with the parts of this item concerning the Containment Pressure Monitor, the Containment Water Level Monitor and the Containment Hydrogen Monitor is outlined below.

Containment Pressure Monitoring - Continuous indication of containment pressure is provided in the control room. Redundant indicators whose inputs are derived from signals used in the Engineering Safety Feature Actuation System are provided on the main control board for a range of 0 to 55 psig. Another set of redundant indicators which monitor the effectiveness of the Containment Vacuum Relief System are provided on the auxiliary equipment panel having a range of +/-5 inches of water column. Additionally, transmitters are provided with a range of -5 psig to 135 psig for containment pressure which will display on the SPDS display located on the main control board. See FSAR Section 6.2.1.1.2 for additional detail.

SHNPP FSAR Page 8 of 16 TMI APPENDIX Containment Water Level Monitoring - Continuous monitoring of containment water level will be provided in the control room and displayed upon demand on the SPDS display located on the main control board. Redundant instrumentation channels are provided to measure a narrow level range from the bottom of the containment sump (Elev 207')

to the top of the sump (Elev 211'). Redundant wide range instrumentation channels are provided to measure water level from the bottom of the containment (Elev 211') to the elevation (Elev 228') equivalent to a 600,000 gallon capacity. Additionally, level transmitters are provided in each of the containment spray pump portions of the containment recirculation sumps with indication in the main control room. The containment recirculation sump besides being displayed on the SPDS, is also displayed on an indicator located on the main control board.

The range covered by the sump transmitters is from near the bottom of the sump (Elev 216' 3")

to the top of the sump (Elev 221' 3") which is sufficient to monitor the minimum water level for the containment spray pump NPSH requirements. See FSAR Section 6.2.1.1.2 for additional detail.

Containment Hydrogen Monitoring - Continuous indication of hydrogen concentration in the containment atmosphere is provided on the hydrogen analyzer remote control panel located adjacent to control room but within the overall control room complex environmentally controlled envelope. There are two redundant hydrogen analyzers with associated control panels which, therefore, provides redundant indication channels. In addition, the hydrogen concentrations will be displayed upon demand on the SPDS. See FSAR Section 6.2.5.2.3 for additional detail.

INSTRUMENTATION FOR DETECTION OF INADEQUATE CORE COOLING (II.F.2)

SHNPP will utilize procedures which provide adequate guidance to facilitate the operator's recognition of inadequate core cooling using instrumentation that will be available when the plant begins operations.

The Westinghouse Owners' Group, of which the Carolina Power & Light Company is a member, has performed analyses to study the effects of inadequate core cooling. These analyses were provided to the NRC "Bulletins and Orders Task Force" for review on October 31, 1979. As part of the submittal made by the Owners' Group, "Instruction to Restore Core Cooling During a Small LOCA" was included. This instruction provides the basis for procedure changes and operator training required to recognize the existence of inadequate core cooling and restore core cooling based on existing instrumentation. The SHNPP will incorporate the key considerations of this instruction into the procedure concerning incidents involving reactor coolant system depressurization and will provide training to the operators in this area. The key considerations which will be incorporated include: indications which are available to identify inadequate core cooling (subcooling monitoring, incore thermocouples, abnormal steam generator pressure, core differential temperature, and source or intermediate range nuclear instrumentation), methods to restore core cooling, and methods to eliminate a non-condensible gas bubble from the reactor vessel.

SHNPP will provide indication of the subcooling margin in the control room. Specific details of the system will be provided in a later amendment. Carolina Power & Light Company has evaluated and is continuing to evaluate the effectiveness of various instrumentation systems with which to detect and indicate inadequate core cooling through a display. Except for the subcooling monitoring described previously, no additional instrumentation has been identified which provides an unambiguous indication of inadequate core cooling or core uncovery.

SHNPP FSAR Page 9 of 16 TMI APPENDIX Carolina Power & Light Company has done extensive investigation of reactor vessel level instrumentation. The designs presently available are neither reliable nor unambiguous.

However, CP&L is continuing to work with potential vendors in an attempt to solve these drawbacks. As additional information becomes available CP&L will inform the NRC.

POWER SUPPLIES FOR PRESSURIZER RELIEF VALVES, BLOCK VALVES, AND LEVEL INDICATORS (II.G.1)

SHNPP compliance with this letter is outlined in FSAR Section 8.3.1.2.35.

IE BULLETINS - REVIEW ESF VALVES (II.K.1.5)

SHNPP procedures will address the positioning of ESF valves and will establish methods of demonstrating on a regular basis that these valves are in their proper position. These procedures will be completed and have been reviewed by the NRC staff prior to fuel load.

OPERABILITY STATUS (II.K.1.10)

Carolina Power & Light Company will review and modify, as necessary, SHNPP procedures for removing safety-related systems from service (and restoring to service) to assure operability status is known.

Procedures will govern the pre-maintenance and post-maintenance safety-related system status. Typically, to remove safety-related equipment from service, two operations documents may be initiated: 1) the Operations Work Procedure (OWP), or 2) the Equipment Inoperable Record (EIR).

An OWP is used in conjunction with an EIR when a specific lineup must be performed due to the component inoperability (such as tripping bistables or isolating containment ventilation), or if a tracking mechanism is needed to verify all compensatory actions are completed within the required times. It may also be used instead of initiating an EIR if all actions and time limits are listed. Double verification lineups are provided on the OWP for maintenance and normal positions if required.

An EIR logs equipment out of service and lists any time limitations that apply. EIRs and OWPs are reviewed at shift turnover to verify time limitations have been met.

Either the OWP or the EIR will list testing required on redundant equipment prior to and during maintenance and testing required to restore operability.

TRIP PER LOW-LEVEL BISTABLE (II.K.1.17)

SHNPP is a facility that does not use pressurizer water level coincident with pressurizer pressure for automatic initiation of safety injection. However, SHNPP does comply with the requirements intent by initiating safety injection upon a low pressurizer pressure signal. The details are described in FSAR Section 7.3.1.1 and Figure 7.3.1.1, Sheet 2 of 7.

THERMAL MECHANICAL REPORT (II.K.2.13)

This item required a detailed analysis of the thermal-mechanical conditions in the reactor vessel during recovery from small breaks with an extended loss of all feedwater. Westinghouse in

SHNPP FSAR Page 10 of 16 TMI APPENDIX support of the Westinghouse Owners' Group has performed the analysis for generic Westinghouse plant groupings to address this issue. The report on this analysis WCAP-10019, "Summary Report on Reactor Vessel Integrity for Westinghouse Operating Plants," was submitted to the NRC in December, 1981. This item is complete.

VOIDING IN RCS (II.K.2.17)

Westinghouse (in support of the Westinghouse Owners Group has performed a study which addresses the potential for void formation in Westinghouse designed nuclear steam supply systems during natural circulation cooldown/depressurization transients. This study has been submitted to the NRC by the Westinghouse Owners Group (letter 06-57, dated 4-20-81) and is applicable to SHNPP.

In addition, the Westinghouse Owners Group has developed a natural circulation cooldown guideline that takes the results of the study into account so as to preclude void formation in the upper head region during natural circulation cooldown/depressurization transients, and specifies those conditions under which upper head voiding may occur. These Westinghouse Owners Group generic guidelines have been submitted to the NRC (letter 06-64, dated 11-30-81). The generic guidance developed by the Westinghouse Owners Group (augmented as appropriate with plant specific consideration) will be utilized in the implementation of SHNPP plant specific operating procedures.

BENCHMARK ANALYSIS - SEQUENTIAL AFW FLOW (II.K.2.19)

Subsequent to the issuance of NUREG-0737, the NRC completed a generic review on this subject and concluded that the concerns expressed in Item II.K.2.19 are not applicable to NSSSs with inverted U-tube steam generators such as those designed by Westinghouse.

Therefore, this item is not applicable to SHNPP and no further action is necessary.

AUTOMATIC PORV ISOLATION (II.K.3.1)

Based on the results of the Westinghouse Report, WCAP-9804, dated February 1981, Carolina Power & Light Company (CP&L) believes that no modifications at SHNPP are necessary.

Carolina Power & Light Company considers this item complete.

REPORT ON PORV FAILURES (II.K.3.2)

The Westinghouse Owners' Group, of which Carolina Power & Light Company (CP&L) is a member, submitted WCAP-9804, "Probalistic Analysis and Operational Data in Response to NUREG-0737 Item II.K.3.2 for Westinghouse NSSS Plants" on March 13, 1981. WCAP-9804 summarizes the Westinghouse PWR owners' collective operational experience for pressurizer PORV and safety valves, and using this data in conjunction with industry-generic probabilistic data estimates the probability of a small-break LOCA caused by a stuck open PORV. With the submission of WCAP-9804 CP&L considers this item complete for SHNPP.

REPORT ON SAFETY AND RELIEF VALVE FAILURES AND CHALLENGES (II.K.3.3)

At SHNPP, any failure of a relief or safety valve will be reported to NRC in accordance with plant LER procedures.

SHNPP FSAR Page 11 of 16 TMI APPENDIX AUTOMATIC TRIP OF REACTOR COOLANT PUMPS (II.K.3.5)

Westinghouse (in support of the Westinghouse Owners Group) has performed an analysis of delayed reactor coolant pump trip during small-break LOCAs. This analysis is documented in WCAP-9584, dated August 1979. In addition, Westinghouse (again in support of the Westinghouse Owners Group) has performed test predictions of LOFT Experiments L3-1 and L3-6. The results of these predictions are documented in the following Owners Group letters to the NRC: 06-49, dated 3-3-81; 06-50, dated 3-23-82; 06-60, dated 6-15-81. Based on: 1) the Westinghouse analysis, 2) the excellent prediction of the LOFT Experiment L3-6 results using the Westinghouse analytical model, and 3) Westinghouse simulator data related to operator response time, the Westinghouse and CP&L position is that automatic reactor coolant pump trip is not necessary since sufficient time is available for manual tripping of the pumps.

Our understanding of the schedule for final resolution of this issue is:

a) Once the NRC formally approves the Westinghouse model, a 3-month study period will ensue during which the Westinghouse Owners Group will attempt to demonstrate compliance with some NRC acceptance criteria for manual RCP trip. The NRC acceptance criteria will accompany their formal approval of the Westinghouse models.

b) If, at the end of the 3-month period, the Westinghouse Owners Group cannot show compliance with the acceptance criteria, the NRC will formally notify utilities that they must submit an automatic RCP trip design.

EVALUATION OF PORV OPENING PROBABILITY (II.K.3.7)

This item is not applicable to SHNPP.

PID CONTROLLER (II.K.3.9)

The SHNPP Proportional Integral Derivative Controller has the derivative action setting set to zero, thereby eliminating it from consideration. No modifications are required for this item.

CP&L considers this item complete.

APPLICANT'S PROPOSE ANTICIPATORY TRIP AT HIGH POWER (II.K.3.10)

No modification to the standard anticipatory trip has been proposed. This item is not applicable to SHNPP.

JUSTIFY USE OF CERTAIN PORV'S (II.K.3.11)

This item is not applicable to SHNPP.

CONFIRM ANTICIPATORY TRIP (II.K.3.12)

SHNPP compliance with this item is outlined in FSAR Section 7.2.1.

FINAL RECOMMENDATIONS, B & O TASK FORCE - ECCS OUTAGES (II.K.3.17)

In the first five years following issuance of an operating license for SHNPP, Unit 1, CP&L will collect the following data on ECC systems and components:

SHNPP FSAR Page 12 of 16 TMI APPENDIX a) Outage dates and duration of outages.

b) Cause of each outage.

c) ECC systems or components involved in the outage.

d) If applicable, corrective actions required.

Test and maintenance outages will be included in the data collection. A report of the data collected will be submitted to the NRC within one year of the end of the five-year period.

EFFECT OF LOSS OF AC POWER ON PUMP SEALS (II.K.3.25)

This item requires that the consequences of a loss of RCP seal cooling due to a loss of AC power (defined as loss of offsite power) for at least 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> be demonstrated.

During normal operation, seal injection flow from the chemical and volume control system is provided to cool the RCP seals and the component cooling water system provides flow to the thermal barrier heat exchanger to limit the heat transfer from the reactor coolant to the RCP internals. In the event of loss of offsite power the RCP motor is de-energized and both of these cooling supplies are terminated; however, the diesel generators are automatically started and either seal injection flow or component cooling water to the thermal barrier heat exchanger is automatically restored within seconds. Either of these cooling supplies is adequate to provide seal cooling and prevent seal failure due to loss of seal cooling during a loss of offsite power for at least 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />.

In the event of a loss of onsite AC power (due to a fire) which causes a loss of seal cooling, the Alternate Seal Injection System will automatically actuate after a time delay and restore seal cooling within 3 minutes of initial loss of seal cooling flow.

Based on this CP&L believes no modifications at SHNPP are necessary in response to item.

CP&L considers this item as complete.

REVISED SB LOCA METHODS TO SHOW COMPLIANCE WITH 10CFR50, APPENDIX K (II.K.3.30)

The Siemens SB LOCA evaluation model was used to analyze the SB LOCA as summarized in Section 15.6.5. The model consists of the following:

1) XN-NF-82-49(A), Revision 1, "Exxon Nuclear Company Evaluation Model - EXEM PWR Small Break Model," June 1986.
2) XN-NF-82-49(P)(A), Revision 1, Supplement 1 and Correspondence, "Exxon Nuclear Company Evaluation Model - EXEM PWR Small Break Model," December 1994.
3) XN-NF-81-58(A), Revision 2, and Supplements 1 through 4, "RODEX 2 Fuel Rod Thermal - Mechanical Response Evaluation Model," Revision 2 and Supplements 1 and 2 dated March 1984, Revision 2, Supplements 3 and 4 dated June 1990.

SHNPP FSAR Page 13 of 16 TMI APPENDIX PLANT SPECIFIC CALCULATIONS TO SHOW COMPLIANCE WITH 10CFR50.46 (II.K.3.31)

The discussion and results of the small break LOCA analysis using the Siemens SB LOCA evaluation model has been incorporated in FSAR Section 15.6.5.

In accordance with the NRC Generic Letter 83-35 (November 2, 1983) this analysis demonstrates compliance with 10CFR50.46.

EMERGENCY PREPAREDNESS, SHORT TERM (III.A.1.1)

Refer to the SHNPP Emergency Plan. The pre-licensing exercise for SHNPP is scheduled for the fall of 1984. Meteorological data collection for emergencies is described in Section 3, SHNPP Emergency Plan.

UPGRADE EMERGENCY SUPPORT FACILITIES (III.A.1.2)

PRIMARY COOLANT OUTSIDE CONTAINMENT (III.D.1.1)

A program designed to reduce leakage from systems outside Containment that would contain highly radioactive fluids during a serious transient or accident will be implemented. This program will be initiated during the preoperational test phase. The program will be performed per approved procedures by qualified personnel.

The program is designed to detect leakage to RAB atmosphere from systems which would be used to bring the plant to a safe shutdown following a serious transient or accident.

a) Systems Included in the Leak Reduction Program A review of the plant design has resulted in the following systems being included in the leak reduction program.

1) Residual Heat Removal System
2) Safety Injection System, except boron injection recirculation subsystem
3) Containment Spray System, except spray additive subsystem and RWST
4) Chemical & Volume Control System
a. Letdown Subsystem
b. Boron Recycle Hold-Up Tanks (RHT)
c. Charging Pumps
5) Post-Accident Sample System
6) Post-Accident RAB Ventilation System

SHNPP FSAR Page 14 of 16 TMI APPENDIX

7) Valve Leakoff Equipment Drain System
8) Gaseous Waste Processing System
9) Seal Water Return System
10) Demineralizer in the Chemical and Volume Control System
11) The portion of the Filter Backwash System that services the A and B RCP Seal Injection Filters
12) The Post-Accident Hydrogen Monitoring System b) System Excluded from the Leak Reduction Program The following systems have been excluded from the leak reduction program because they will not be used to mitigate the consequences of an accident:
1) Chemical and Volume Control
a. Boron Thermal Regeneration System
b. Boric Acid Transfer System
2) Filter Backwash System
3) Fuel Pool Cooling and Cleanup System
4) Radioactive Waste Disposal Systems
5) Process Sampling System c) Explanation for Exclusion of Systems from Leak Reduction Program
1) Chemical and Volume Control
a. The Boron Thermal Regeneration System (BTRS) will not be tested for the following reasons:
1) The BTRS will not be used in a post-accident situation.
2) The BTRS has no functional design characteristics which can be used for post-accident mitigation.
3) The BTRS was not included in the list of systems requiring testing by NUREG 0737.
b. The Boric Acid Transfer System will not be used, because boration will be provided by adding borated water from the Refueling Water Storage Tank while letting down to the Recycle Holdup Tank.

SHNPP FSAR Page 15 of 16 TMI APPENDIX

c. The only component within the Boron Recycle System that may be used post-accident is the Recycle Holdup Tank (RHT). This will allow a letdown path to be established for reactor coolant in order to provide the volume reduction required to permit boration. The feed pumps and feed filters will not be required post-accident, because total letdown for boration would be adequately held by the 84,000 gallon RHT during the post-accident phase. Treatment of the effluent in the RHT will not occur until the recovery phase, well after the post-accident phase. Actions at that time can be thoroughly planned and deliberate. Therefore, although the RHT will be included in the leak reduction program, the balance of the system need not be.
2) Filter Backwash System The filter backwash system is designed to collect materials back flushed from the filters within systems such as the chemical and volume control system. Filters which are part of systems included in the leak reduction program will be included in the boundary subject to the leak reduction program. Such filters are not in service during safety injection or recirculation and can be manually bypassed in the event the pressure drop becomes too great or during flushing operations.

The back flushing portions of the system are operated manually and the back flushing alignment exists for only short periods of time. Backflushing is not likely to occur following an accident since it would only tend to spread contamination.

Therefore, CP&L concludes that this system does not need to be included in the leak reduction program.

None of these systems are required by NUREG 0737 Item III.D.1.1 to be included in the leak reduction program, and CP&L believes that no significant benefit would be derived from their inclusion.

3) Fuel Pool Cooling and Cleanup System The SER stated that the Fuel Pool Cooling and Cleanup system should be leak tested to minimize leakage that might occur during a serious transient or accident (i.e. fuel handling accident). The Fuel Pool Cooling and Cleanup System is used to maintain water quality in the fuel pools and as such can reduce the contamination present in the fuel pools. However, the fuel pools do not have a significant inventory of radioactive material following a fuel handling accident since all noble gases are assumed to escape from the pool surface. This postulated accident, even when conservatively analyzed contributes only .02 microcuries of iodine per gram to the activity of the water. CP&L does not consider this to represent a highly contaminated system, especially within the context of TMI Item III.D.1.1.

We concluded that this system need not be included in the leak reduction program.

4) Radioactive Waste Disposal
5) Process Sampling System

SHNPP FSAR Page 16 of 16 TMI APPENDIX The Process Sampling System is not used for post-accident sampling. In accordance with NUREG-0737, Item II.B.3, a separate Post-Accident Sampling System (PASS) is used. A description of the PASS is found in FSAR Section 9.3.2.2.3. The PASS will be leak tested as provided in our commitment for testing.

Carolina Power & Light Company has evaluated potential leak paths as discussed in NRC letter regarding the North Anna incident dated October 17, 1979. Design changes will be implemented, if need is identified, prior to fuel load to eliminate the open paths to the atmosphere as discussed in the letter.

The leak reduction program employs visual inspections of the mechanical joints and seals of the system to detect leakage and measurement of observed leakage. These inspections will be conducted with the system pressurized to normal operating pressure using the system fluid as a test medium. The observed leakage will be documented and compared against the acceptance criteria. Corrective action will be taken as appropriate, but in all cases will be to reduce leakage to as-low-as-practical levels. Testing of gaseous systems will include helium leak detection or equivalent testing methods. The initial leak test submittal will be made two months prior to fuel load.

After commercial operation a program of preventative maintenance to reduce leakage to as-low-as-practical levels will be established and implemented. The program will include periodic leak tests at each refueling cycle interval or less.

INPLANT IODINE RADIATION MONITORING (III.D.3.3)

CP&L Response to NRC Position and Clarification The Shearon Harris Nuclear Power Plant will comply with the requirement to accurately detect the presence of iodine in regions of interest following an accident in the following manner.

The SHNPP will have the capability to analyze for airborne iodine in a counting laboratory which has a low background, low contamination and will be ventilated with clean air. This capability includes the ability to analyze effluent charcoal samples. If the counting laboratory background and contamination levels exceed established limits, the counting facilities of the Harris Energy and Environmental Center and other CP&L nuclear facilities will be utilized.

CONTROL ROOM HABITABILITY (III.D.3.4)

SHNPP compliance with this item is outlined in FSAR Section 6.4 as augmented by FSAR Section 9.4.1.
