0 INTRODUCTION PURPOSE The purpose of this study was to verify that the effects of any high energy line break (HELB) on any nonsafety-related control systems in Nine Mile Point - Unit 2 (NMP2) do not result in an event more severe than the events analyzed in Chapter 15 of the NMP2 Final Safety Analysis Report (FSAR). This study responds to concerns expressed in the NMP2 Safety .Evaluation Report Section 7.7.2.2 and to NMP2 FSAR Question F421.43.

1.2 SCOPE OF STUDY The scope of this HELB analysis was restricted to HELBs and their impact on those components of nonsafety-related control systems which could initiate a reactor transient. A list of such compo-nents was developed based on the system elimination criteria pre-sented in Section 2.1 and the component elimination criteria identified in Section 2.2 of this report. HELB zones containing both control systems components of interest and HELB locations were defined using the appropriate Equipment Qualification Environmental Design Criteria (EQEDC) zone maps as a guide, as described in Section 2.4 of this report. Each HELB zone was analyzed, the results summarized, and final conclusions and recommendations are presented in Section 4.0.

SUMMARY

A systematic study has been conducted to determine the conse-quences of postulated HELBs and their effects on nonsafety-related control system components located in the affected zone.

The detailed analysis (Appendix D) describes each of the postu-lated HELB events and their limiting effects on the reactor pa-rameters. The detailed analysis ip Appendix D is summarized in Section 4.0. With the exception of the loss of feedwater heating exacerbated by a turbine trip, the effects of the postulated HELB/control systems failure events are less severe than the Unacceptable Results for Incidents of Moderate Frequency - Antic-ipated Operational Transients presented in FSAR Chapter 15.

Those events caused . by break of reactor coolant pressure boundary (RCPB) piping are bounded by the limiting fault events described in Chapter 15, It is concluded that safe reactor shut-down is ensured for all events postulated herein, and the con-sequences of these events do not result in any significant risk to the health and safety of the public.

2.0 METHODOLOGY The following criteria and assumptions were used to develop the scope of work for the subject HELB analysis:

0143-12177-HC3

1. Identify all nonsafety control systems and components which could impact the critical reactor parameters (e.g., water level, pressure, critical power ratio).

2. Identify high energy lines and their. postulated break loca-tions and evaluate consequences.

3. Identify the plant zones which. contain both HELB locations and control system components determined in Item 1 above.

4.. Postulate pipe breaks in each of the zones defined, deter-mine which control system components are affected, and ana-lyze the consequences of failure of the control system components.

5. Combine the effects of the HELB with potential, simultaneous malfunctions of control system components in the postulated HELB zone and determine the effects on the critical reactor parameters.

6. Verify that the effects on critical reactor parameters are enveloped by the analyses in Chapter 15 of the FSAR.

7. Identify any postulated events that are beyond Chapter 15 analyses and recommend correct'ive actions.

2.1 SYSTEM ELIMINATION All nonsafety-related control grade systems which may affect the critical reactor parameters have been included in the HELB analy-sis, and the following elimination criteria were applied to ex-clude some of the systems from further analysis.

Elimi-nation Criteria Basis Nl Nonelectrical systems, i.e, mechanical and struc-tural systems comprised only of structural steel, piping, tanks, cranes, and similar equipment.

N2 Instrumentation systems with no direct or indirect controlling function, such as the annunciator sys-tem. Instrumentation and dedicated inputs to the process computer, as well as the computer itself, are excluded.

N3 Control systems that interface or interact with the reactor operating system but have no direct or indi-rect effect on reactor parameters, such as ventila-tion systems.

0143-12177"HC3 2

N4 Control systems that do not interact or interface with reactor operation or reactor parameters either directly or indirectly, such as communications, lighting, etc.

N5 Systems which are used only during startup, shutdown or refueling mode.

N6 Electrical systems and components involved in power distribution or transformation the loss of which will not impact the reactor parameters or safety system performance.

N7 All safety-related systems or safety-related por-tions of control systems.

A list of all systems with the elimination criteria identified is included in Appendix A.

2.2 COMPONENT ELIMINATION Instruments and components for those systems which are eliminated under system elimination criteria are excluded from the list of plant components.

The following elimination criteria are applied to the remaining components to arrive at the final list of components considered in the detailed HELB analysis. The appropriate system piping and instrumentation diagrams and elementary diagrams have been used to aid in this elimination.

Mechanical components (e.g., structural steel, tanks, pipes, valves) are not considered control systems components sub-ject to failure. However, instrument taps and tubing for components of interest, which may be physically "located on mechanical components, are, included.

2. Instruments and other dedicated inputs to the process com-puter are eliminated.

3. Components that provide only position status information and do not perform any control function are eliminated. This includes position switches on air- and motor-operated valves which are not interlocked with other equipment.

4. Components that provide only indication and/or inputs for alarms or recording devices are eliminated.

In general, initiating type control components, such as elements, switches, transmitters, controllers, and converters, are included in the detailed HELB analysis, along with their related taps and process tubing. Motor control centers (MCC) in the affected zones were considered as components subject to failure and were 0143"12177"HC3

reviewed for MCC-mounted control components or power supply to components of interest. No nonsafety grade control system compo-nent in this analysis is mounted in or powered directly. from an MCC, and MCCs were, therefore, eliminated.

A list of components which have been considered for analysis based on the above criteria and their control functions are in-cluded in Appendix B.

2.3 HIGH ENERGY PIPE CRITERIA The criteria for determining high energy lines used in the study were based on criteria established in Section 3.6 of the NMP2 FSAR. High energy piping is defined as those fluid systems that during normal plant conditions, either are in operation or are maintained pressurized under conditions where either 'or both of the following are met:

1. Maximum operating temperature exceeds 2004F

2. Maximum operating pressure exceeds 275 psig Those high energy lines that operate above these limits for less than 2 percent of the time and are, required to perform their in-tended function are classified as moderate .energy lines and, therefore, are excluded from the scope of this study. Piping whose diameter is 1-in. NPS or smaller is also excluded.

A list of all the high energy lines considered for this analysis is included in Appendix C.

2.4 ZONE DETERMINATION For the purpose of this analysis, the EQEDC zone map was used for

,identifying normal operating environmental zones. These EgEDC zones wire subdivided into HELB zones which are open areas bound-ed by walls, ceiling, floors, etc. Each HELB zone is uniquely identified. Certain HELB zones extend between elevations because some floor elevations consist of open grating or a hoist opening

~

'he is common to all the floors.

turbine enclosure is divided into discrete zones with unique identification. A HELB event in a small cubicle can conceivably blow out the door and the pressure/temperature transient may fail all nonsafety grade instruments in the adjoining larger volume zone. However, a pipe break in a large-volume zone will not impact its neighboring cubicled zone because the larger volume and more outlets associated with it provide easier alternate paths of energy dissipations. 'These considerations have been factored into this analysis by combining the following zones:

26. Zones S and AE combined for a break in AE

27. Zones AF and AE combined for a break in AE

28. Zones S and AF combined for a break in AF Zone Y does not contain high energy lines and is not affected by high enexgy line breaks in other zones. Therefore, this zone is not analyzed.

Zone maps are provided in Figures 1 through 6 at the end of the report.

The sacrificial approach used throughout the analysis assumed that any HELB within a defined zone would impact all control system components in the zone. Because of the large area covered by Zone D, the potential impact of a line break was further analyzed to verify if a break at one end of the turbine building can realistically fail nonsafety grade components located at the other end with intervening barriers, such as pipes, tray supports, turbine casing, etc. It: was determined that in the condenser (Zone B) and heater bay areas (Zones F, G, and H), a pipe break may affect the components in only a confined portion of an "architecturally" defined zone. While the distance between the postulated high energy line break and. control components pre-cludes the possibility of. physical damage to components due to direct pipe whip and jet impingement, the bays allow for the adverse environment associated with the break to spread through-out the condenser or heater bay,. minimizing the environmental effects.

0143-12177-HC3

Therefore, even though no air/steam/water boundary exists in the condenser and heater bay areas, the above consideration has been used in the analysis of Zone D and the sacrificial approach ap-plied within the confines of the zone determined above.

For the reactor building/secondary containment, a list of the nonsafety components which affect the reactor parameters was made. The locations of the components were then checked', to de-termine whether these components are affected by any HELB event in their vicinity, and the consequence of their failure was analyzed.

Reactor core isolation cooling (ICS) (steam side), reactor water cleanup (WCS), and control rod drive (RDS) system piping are the only sources 'of HELB events in the secondary containment, which are capable'f producing 'emperature transients resulting in failure of all nonsafety grade instruments in the zones identi-fied in the EQEDC report. A review'f the relevant drawings iden<<

tified seven zones to be considered for analysih.

These zones have been treated as one zone for purposes of analy-sis. This was done because all zones in the secondary contain-ment communicate with each other for environmental purposes.

While the high energy lines do not pass through zones containing nonsafety-related control devices, a break in these lines may cause adverse environmental conditions in those zones which do contain nonsafety-related control devices.

All areas of the radwaste, diesel generator, normal switchgear,

,standby gas, screenwell, and control buildings were eliminated from analysis because the systems in these areas do not affect reactor parameters. Although. the switchgear room east (Zone AE) contains high energy lines, an analysis of the electrical system equipment in this zone indicated that there are no adverse effects on reactor parameters resulting from a HELB in this zone. The auxiliary boiler building has been eliminated because it contains auxiliary steam system components, and a HELB failure can lead to a single system failure only which cannot affect reactor parameters.

2.5 PIPE BREAK LOCATION AND EFFECTS 2Q.1 Pipe Break Location The high energy pipes identified in Appendix C are assumed to break at all locations where control systems components of inter-est (as defined in Section 2.2) are physically located in the same zone as the high energy piping, unless piping runs subject to high stress have been specifically identified and analyzed as a result of the studies in FSAR Section 3.6. Piping evaluated by means of previous HEIB studies (see FSAR Section 3.6) is consid-ered to break as defined in those studies. Only one pipe break is postulated to occur at any time and only during normal plant conditions. As part of the detailed analysis described in 0143-12177"HC3

Appendix D, the worst case combination of a specific HELB and consequential control systems failures is examined for the reac-tor in the limiting condition for that postulated'vent.

2.5.2 Pipe Break Effects Pipe breaks and consequential control system failures are evalu-ated considering the effects of adverse environment, pipe whip, and jet impingement on the control system components.

l. Environmental Effects The effects associated with any adverse environment (in-creasing humidity, temperature, pressure, radiation) are enveloped by employing the sacrificial approach. The sacrificial approach assumes that any HELB within the de-fined zone would adversely impact all control systems corn" ponents in the zone. Using this approach, environmental effects are enveloped in the detailed analysis presented in Appendix D.

The turbine generator electrohydraulic system (TMB) is a high pressure, low temperature system with a limited volume of EH liquid maintained at" high. pressure by a small capacity pump. It is inconceivable that a pipe break in this system will incapacitate all nonsafety grade instruments in the zones of TMB system pipe routing, and an exception to the sacrificial approach in this case is considered justified.

Direct jet impingement or direct pipe whip are considered as the only causes of failure for those nonsafety grade instru-ments that are within such bounds.

Instrument air supply. line failure due to a HELB may cause the controlled component to fail in the designated safe position and, since the worst failure mode has been con-sidered in the analysis, air tubing failure is inherently enveloped by this study.

2. Pipe Whip Considerations Movement of a . circumferentially broken pipe is assumed to occur in the direction of the jet reaction while the pipe hinges at the nearest rigid support, anchor, or penetration, producing an arc of motion. The pipe is allowed to move in an arc with a radius from the break to the hinge point, and motion is assumed to be limited by pipes of equal or greater diameter or reinforced concrete walls, floors, or columns.

The whipping pipe is assumed capable of incapacitating any control systems components within the arc of motion. The sacrificial approach envelops these pipe whip considera-tions.

0143-12177-HC3

3. Jet Impingement Considerations Jet impingement is considered for both circumferential and longitudinal breaks. The basic approach assumed is that the jet from a postulated break is sufficient to fail all impacted components within the jet cone of influence~> except in those areas where major structures provide natural barriers. The sacrificial approach used in this analysis envelops these jet impingement considerations.

2.6 PLANT WALKDOWN Plant walkdown was conducted in two phases.

Zone maps for the reactor building, turbine building, and auxiliary bays were used during a plant walkdown to accurately define appropriate zones, giving due consideration to wall heights, location and types of doors, wall openings, etc. It was assumed that the locations of the high energy lines, control components and their associated taps and tubing are correctly represented in the referenced drawings. The results of this walkdown were incorporated in Revision 0 of this study.

A subsequent plant walkdown was conducted in Phase 2 to verify the location of control systems components and assess the proxim-ity of the components and associated taps and tubing to the high energy lines. The appropriate architectural, piping, and instru-ment location drawings were used for this purpose.

termined that some control components are located in zones dif-It was de-ferent from those assumed previously. Impulse and signal lines of certain components have been routed through a zone other than where the components of interest are located. Appendix D identi-fies such components by noting that they have been analyzed for the failure mode resulting from a break in process tubing only.

It was also established that HELB in the, turbine electro-hydraulic system will not incapacitate any additional nonsafety grade control components of .interest beyond those already in-cluded in this analysis.

All changes resulting from this walkdown have been reflected in Revision 1 of this report, and the changed areas are identified by a revision bar in the right-hand margin.

Instrument air supply line failure due to a HELB may render the controlled component to fail in the designated safe position and, since the worst failure mode has been considered i;n the analysis, air tubing failure is inherently enveloped by this study.

2.7 HELB ZONE ANALYSIS The detailed analysis was performed on a zone basis. The follow-ing description is representative of the analysis performed for each HELB zone. Appendix D, which presents the details of the analysis for each zone, follows this format.

0143-12177-HC3

.0 High Energy Systems Under each zone, the line for each system is listed based on its function. Each high energy line was reviewed to deter-mine the effects of a piping failure upon its own system.

This is done for each high energy line or group of lines having the same function independently, since only a single pipe break is postulated as the initiating event. The ef-fect of the break itself on reactor parameters was examined.

Due consideration has been given to interactions between adjacent zones as explained in Section 2.4.

2. Control Systems A list was made of all control system components within the zone .on a system basis. Where control components were grouped together, they have similar system failure effects.

The failure mode(s) of each component or group of components and the effects of their failure were reviewed. The worst possible mode as a result of single or group of components failure has been identified in the analysis. Where the worst.-mode is not readily discernible, all failure modes and their consequences have been analyzed.

3. Combined Effects The postulated piping failure for each HELB in the zone was examined in combination with the resulting worst case fail-ures of control system components in the zone to determine whether any combination of possible failures could exacer-bate the postulated HELB. The sacrificial approach was used, and the worst case combined HELB and possible conse-quential control system failures were defined and analyzed.

The consequences of these events were compared to the acci-dent and transient analyses presented in FSAR. Chapter 15, which include discussions of a single additional active com-ponent failure to ensure that they are bounded by existing FSAR Chapter 15 analyses.

3.0 DISCUSSION OF ANALYSIS The following conditions can occur individually or in combination as described under Combined Effects in Appendix D.

Turbine trip due to a loss of condenser vacuum.

2. Turbine trip due to high vibration.

3 ~ Turbine trip due to a high water level in the moisture separator.

4. Loss of feedwater flow due to a gradual loss of condensate inventory.

0143-12177-HC3

5. Complete loss of feedwater.

6. Loss of one or more reactor feed pumps.

7. Partial loss of feedwater heating.

8. Loss of RCIC pump.

9. Loss of one RCS pump.

10. Feedwater controller failure - Maximum demand.

Combination of hypothesized conditions.

Each of these conditions is analyzed below to determine the over-all consequences on reactor parameters.

I

l. A loss of main condenser vacuum could result either from a break in a high energy line leading to the condenser or steam jet air ejector or from a break in one'f the turbine sealing steam supply lines, allowing air leakage at the low-pressure turbine shaft seals. A loss of sealing steam would produce a much more gradual loss of condenser vacuum than would a break in a line from the condenser. Both con-ditions would lead to a turbine trip situation, which is bounded by Chapter 15.2.5 of the FSAR.

2-.- A turbine trip due to high vibration as a result of water induction could also lead to a "turbine trip with bypass" situation, since the bypass would not be affected and would operate as required.

3~ A turbine trip could occur as a result of a high level sig-nal from the moisture separator. This could occur either as a result of an actual high level or from a malfunctioning of the moisture separator high level switches. This would also result in a tu'rbine trip with bypass situation.

4. A loss of feedwater flow could result when a gradual loss of condensate occurs. Any high energy steam or water line break which could result in a loss of condensate at a rate which would exceed the maximum available condensate makeup is assumed to result in a gradual reduction in condensate inventory. The low hotwell level could ultimately trip feedwater pumps on low suction pressure.

5. A complete loss of feedwater would result when one of the main condensate or feedwater lines is assumed to rupture.

The feedwater pumps would no longer be able to feed the re-actor vessel, which would quickly lead to a reactor scram on low water level. This loss of feedwater flow transient is bounded by Section 15.6.6 of the FSAR."

0143-12177 "HC3 10

6. A loss of one reactor feedwater pump would result in a plant runback to no less than 68 percent of reactor rated load.

The remaining pump will not be started automatically; however, it is expected that it will be started manually to allow the plant to resume full load.

7. A partial loss of feedwater heating could occur when:

a. Steam extraction lines to heater are broken

b. Drain lines are ruptured

c. Heater controls are adversely affected

d. Feedwater/condensate is bypassed around heater, or

e. A heater string (train) is isolated.

The largest postulated reduction in feedwater temperature assumes the loss of the third through sixth feedwater heaters of one train and the partial loss'f fifth and sixth point heaters and second. and third point drain coolers of the other trains. A decrease in feedwater temperature of less than 1004F results in no adverse effect on reactor parameters. This event is bounded by Section 15.1.1 of the I FSAR.

8. Loss of reactor core isolation cooling pump can result from a break in the RCIC steam piping, but the break is auto-matically isolated by resultant high ambient temperature sensors, which are not postulated to fail (QA Category I).

9. Tripping a single reactor recirculation pump due to a fail-ure of instrumentation requires no safeguard or protection system operation as analyzed in FSAR Section 15.3.

10. Failure of feedwater control system could occur as a result of either feedwater flow transmitter failing the controller in maximum demand or feedwater flow valves failing in full open position. This event will lead to a high reactor vessel level causing reactor scram, turbine trip, and main feedwater pump trip. Failure of feedwater controller in maximum demand event is bounded by Section 15.1.2 of the FSAR.

The worst hypothesized combination of the above conditions can occur from a pipe break within the turbine building, which may simultaneously cause a partial loss of feedwater heating (condition 7) and a turbine trip (condition 1 or 2) if the appropriate controls are disabled, leading to improp-er valve positioning.

0143"12177-HC3

The reduction in feedwater inlet temperature causes a gradu-al rise in reactor power and, depending upon the specific timing of the event, the turbine trip may occur at a reactor power elevated between the operating value and the trip lev-el. It has been concluded that the occurrence of this event is highly unlikely. This conclusion is based in part on consideration of the probability that a combination of the following worst case conditions occurs concurrently:

a. The worst case pipe segment breaks on the most impor-tant line.

b. Pipe whip or jet impingement can strike all targets in an area and cause failures in worst case modes.

c. Breaks occur at worst case locations.

d. Both turbine trip and reactor high power>>level trip occur at appropriate (i.e., worst case) times.

Should the unlikely worst case combined sequence occur, the reactor may experience for a short time a change in critical power ratio (CPR), which is not covered under existing FSAR Chapter 15 analyses for the Unacceptable Results for Inci-dents of Moderate Frequency - Anticipated Operational Transients. However, the effects of this accident event, even considering a single active component failure in a mitigating safety system, pose no threat to the unacceptable results for Limiting Faults - Design Basis (Postulated)

Accidents presented in the FSAR Chapter 15.

All other combinations of the first ten conditions result in effects which are bounded by previously reported tran-sient conditions as analyzed in FSAR Chapter 15 and noted in Appendix D. It is concluded that the hypothesized HELB, with resulting effects on control systems, poses no signifi-cant risk to the health and safety of the public. There-fore, no further accident analysis or any design modifica-tion is necessary.

4' CONCLUSIONS AND RECOMMENDATIONS The detailed analysis of Appendix D presents a thorough dis-cussion of the analysis performed for those zones of the Turbine Building, Reactor Building, and Auxiliary Bay which required evaluation under the criteria set forth in Section 2.0. The sacrificial approach, as outlined in Section 2.7, with the exception noted in Section 2.5.2, has been strictly applied, and conservative assumptions have been made to all analyses of system failure. No credit has been taken for operator action in any event beyond those already assumed in the existing FSAR Chapter 15 analyses.

0143-12177-HC3 12

The worst case combined effects of the postulated HELB and conse-quential control systems failures have been examined and detailed in the Combined Effects section of Appendix D for each zone or related zones. In many cases, the postulated HELB is not exacer-bated by any combination of control systems failures in the zones. In some cases, control system component failures had in-significant effect on the controlled system and no further analy-sis was made. The applicable bounding FSAR Chapter 15 event has been referenced in the Combined Effects section of Appendix D for each zone where appropriate. These FSAR sections include the discussion of the effects of a single additional active component failure in a mitigating safety system and conclude that the combined consequence of failure is bounded by the existing analysis as described in Section 3.0 of this report entitled Discussion of Analysis.

Failure Effect These devices provide CRD cooling water flow control.

Potential effects of failure include loss of instrument air pressure and closure of valves 2RDS-FV6A (C12-F002A),

2RDS-FV6B (C12-F002B) leading to an increase in CRD tem-perature and potential rod block.

3) 2RDS-FV6A (C12-F002A)) 2RDS-FV6B (C12-F002B)

Failure Effect Failure of these valves to the closed position would re-sult in loss of instrument air and loss of cooling water flow leading to an increase in CRD temperature and poten-tial rod block. Failure of these valves such that they remain open is of no consequence.

4) 2RDS-PCV101 (C12-F003), 2RDS-SOVX7A and 2RDS-SOVY7A (C12-F007A), 2RDS-SOVX7B and 2RDS-SOVY7B (C12-F007B),

Failure Effect Recirculati.on pump thermal shock interlock. Worse case failure would result in transfer to low frequency MG set.

2) 2RCS+PT84B (B35-N050B)

Failure Effect High drywell pressure. Worse case failure would inhibit motion of recirculation flow control valve. No effect at full power.

3. Combined Effect A break in any of the reactor core isolation cooling (RCIC) high energy lines in this zone will result in a loss of steam to reactor core isolation cooling turbine. This pipe break will result in closure of containment isolation valves for the ICS turbine steam supply due to high area ambient temperatures.

This will cause loss of RCIC pump trip bounded by FSAR Section 15.3.1 analyses.

Failure of CCP system (RBCLCW) control components has no sig-nificant effect since this system is not required to operate during emergency or faulted plant condition. However, during this condition, a portion of the system provides a Cat I pres-sure boundary for backup cooling from the service water system to cool the SFC heat exchangers, RHR pump seal coolers, and recirculation pump seal coolers.

Failure of the condensate makeup/drawoff control component (2CNS-PCV132) to maintain condensate water pressure of 100 psig to spent fuel pool cooli4g and cleanup, radioactive liquid waste, and high pressure decontamination has no significant effect.

Failure of the instrument air system control components will cause loss of air supply to recharge ADS accumulator tanks.

Since these tanks are isolated and contain sufficient volume to operate the ADS system when required, no significant effect will result.

Failure of the control rod drive system control components will lead to the following:

1) Loss of instrument air pressure (no significant effect)

2) A reactor scram 0390-12177-HC3 D-RXB-6

Failure of feedwater control system control components will result in feedwater controller failure in maximum demand.

Increased feedwater flow to reactor will result in reactor high water level scram. This event is bounded by FSAR 15.1.2.

Failure of recirculation system control components will result in transfer of recirculation pump to low speed. This event is less severe ~n described in FSAR Section 15.3.

b. A break in the reactor water cleanup high energy line in this zone will cause loss of reactor water cleanup return line to feedwater system. This event is bounded by FSAR Section 15.6.6. Failure of control components in this zone is described in Item 3.a.

The significant conse-quences of such a failure have been integrated into the analysis by referring to the appropriate "Failure Effect" from the above listed zone(s) in the "Combined Effect" section of this zone.

a. Condenser Air Removal (ARC 5-1) 2ARC-LS111 Failure Effect Failure of the above level switch will cause the air removal recovery tank 2ARC-TKI isolation valve 2ARC-SOVlll to the main condenser to open. This vill cause the tank to drain its con-densate to the. main condenser and expose the tank to the main stack which will result in a gradual loss of condenser vacuum.

b. Auxilia Steam (ASS 3-9) 1)- 2ASS-PIC125 0393A"12177-HC3 D-AA-3

Failure Effect Failure of this device may 'cause main steam pressure con-trol valve for off-gas, 2ASS-PV125, to close resulting in loss of heating steam for off-gas preheater, 20FG-ElA and 20FG-ElB. This will reduce performance in the off-gas recombiners, 20FG-RBNRlA and 20FG-RBNR1B. Auxiliary steam is the backup supply for this system.

2) 2ASS-PIC140 Failure Effect of this dev'ice may cause auxiliary steam pressure o'ailure control valve, 2ASS-PV140, to close resulting in loss of heating steam for off-gas preheaters, 20FG-EIA and 20FG-E1B. This will reduce performance in the off-gas recombiners, 20FG-RBNRlA and 20FG-RBNR1B. Main steam is the normal supply for this system.

If these devices fail such that shutdown of the vacuum pumps due to high radiation is prevented and vacuum pump inlet and outlet valves are maintained open, inadvertent release of off-gas to the main stack wili result.

6) 20FG-AOV103 20FG-SOV103 Failure Effect Failure of the above air>>operated stack isolation valve in the closed position will affect the capability of the off-gas system to operate properly, resulting in eventual loss of condenser vacuum.

Failure of the stack isolation valve in the open position may inadvertently release radioactive off-gas to the main stack.

7) 20FG-I/P71A 20FG-PT71A 20FG"PIC71A 20FG-SOV14A 20FG-I/P71B 20FG"PT71B 20FG-PIC71B 20FG-SOV14B 0393A"12177"HC3 D-AA-5

20FG-SOV70A 20FG-SOV70B Failure Effect If failure of these devices causes auxiliary steam supply inlet valves to close, a loss of auxiliary steam supply to the associated off-gas preheater will result. This may affect off-gas catalytic recombiner efficiency.

2. The following is the list of nonsafety-related control components that are affected by a high energy line break on any of the lines listed in Item 1. The consequence of failure of each control compo-nent is analyzed. Refer to Appendix B for function of individual components.

Additionally, a high energy line break .in this zone will also result in failure of control components in Zones D and AB. The significant consequences of such a failure have been integrated into the analy-sis by referring to the appropriate Failure Effect from the above listed 'zones in the Combined Effect section of this zone.

a. Condensate Demineralizer (CND, 4-7) 2CND-FV294

" -" -Failure Effect Failure of condensate system recycle outlet valve 2CND-FV294 in open position will bypass a portion of demineralized condensate to main condenser, resulting in additional inventory to main

'ondenser. Condensate hotwell level is maintained by level control valve 2CNS-LV103 and LV105. Therefore, failure of 2CND-FV294 has no significant effect.

b. Condensate (CNM, 4-1) 2CNM-TV121 Failure Effect If temperature valve 2CNM-TV121 fails closed, high turbine hood temperature can result, which can trip turbine.

e. Hot Reheat S stem (HRS, 3"3)

1) 2HRS-PS 107 Failure Effect'ailure of the above pressure switch will cause inadver-tent closure of moisture separator reheaters 2MSS-ElA, B, main steam supply valves 2MSS-AOV92A) B, which can result in reduction of hot reheat steam temperature to low-pressure turbine.

Failure of this instrument will also cause inadvertent opening of moisture separator drain receiver tanks 2DSM-TK4A, B drain valves 2DSM-LV78A, B to the main con-denser which will r'esult in partial loss of feedwater heating in the 4th point heaters 2CNM-E4A, B, C.

2) 2HRS-PS108 Failure Effect Failure of the above pressure switch will fail the valves 2DSR-AOV82A, B in the open position,'alves 2DSR-AOV83A, B in the close position, and 2DSR-LV68A, B in the open posi-tion, which will result in a partial loss of feedwater heating in the 6th point heaters 2FMS-E6A) B, C.

3) 2HRS-CIV1, 2HRS-CIV2, 2HRS-CIV3) 2HRS-CIV4) 2HRS-CIV5, 2HRS-CIV6 Failure Effect Failure of any or all of the above control valves in the close position will result in partial or total loss of hot reheat steam to the low-pressure turbines, 2TMS-T2A, B, C.

This will cause a turbine trip.

Failure .E ffect Failure of the above pressure switches (one out of three X and one out of three Y) may cause inadvertent turbine trip. Also, failure of these instruments may prevent tur-bine trip during low condenser vacuum. This event will not pose any serious threat to the reactor because Category I condenser vacuum transmitter 2CNM-"PT46A) B, C, D) will signal the main steam isolation valves to close and the reactor to scram.

2) 2TMA-TS3A) 2TMA-TS3B, 2TMS-T3C Failure Effect Failure of any or all of the above temperature switches such that turbine exhaust hood temperature high-high is indicated will result in turbine trip.

Failure of all of the above temperature switches to indi-cate turbine exhaust hood high-high temperature would pre-vent turbine trip and possibly cause high turbine vibration and trip.

Since this pump is used only during low turbine RPM or startup condition, failure will. not impact normal operation of the plant.

k. Turbine Generator Exhaust Hood S ra (TMS, 16-9) 2TMS"TT101, 2TMS-TT102, 2TMS-TY103 Failure Effect Failure of the above temperature transmitter may cause inadver-tent closure of exhaust hood condensate temperature control valve 2CNM-TV121, causing high exhaust hood temperature which can cause high turbine vibration at low load or startup condi-tions. During normal plant operation (higher loads), no ad-verse effect occurs whether the temperature control valve is closed or opened.

3. Combined Effect

a. A break in any of the condenser air removal high energy lines in this zone will result in a loss of main condenser vacuum.

0115-12177"HC3 D-A"18

This event is bounded by FSAR Section 15.2.5 analyses. As a result of the high energy line break in this zone, control components in this zone or zone AB or zone D may fail, result-ing in any or all of the following events:

1) Turbine trip in Zone A and Zone D, an event bounded by FSAR Section 15.2.3 analyses.

2) Loss of main condenser vacuum in Zone A, Zone AB, and Zone D, an event bounded by FSAR Section 15.2.5 analyses.

3) Toss of feedwater heating in 4th and 6th point heaters in Zone A, and 5th and 6th point heaters and second and third point heater drain coolers and in only one of three forth point heaters in Zone D, an event bounded by FSAR Sec-tion 15.1.1 analyses.

4) Ioss of feedwater flow (Zone D), an event bounded by FSAR Section 15.2.7 analyses.

5) Feedwater controller failure - maximum demand (Zone D), an event bounded by FSAR Section 15.1.2 analyses.

If the turbine trip occurs at a reactor power level ele-vated from initial operating value due to the loss of

-feedwater heating, the reactor may experience a change in critical power ratio greater than that described in the unacceptable results of incidents of moderate frequency anticipated operational transients of FSAR Chapter 15.

See Section 3.0 for further discussion.

b. A break in any of the auxiliary steam high energy lines in this zone will result in a loss of main condenser vacuum. This event is bounded by FSAR Section 15.2.5 analyses. The failure of control components in this zone or Zones AB or D is de-scribed in Item 3.a.

C ~ 1) A break in the auxiliary condensate high energy line (Item 1.C.1) results in loss of condensate to the third point heaters.

e ~2' break in the condeasate makeup and drawoff high energy lines in this zone (Item l.e.2) will result in loss of control rod drive cooling water supply and loss of operator ability to coa-trol rods manually. Loss of rod drive cooling water will re-sult in no immediate significant effects; over the long term, some deterioration of control rod mechanism seals may occur.

If the reactor is ih automatic control, loss of ability to man-ually move control rods will have no immediate effect. Ulti-mately, other effects which change reactivity will drive the automatic control system out of raage and the reactor will ex-perieace slowly decreasiag or increasiag reactor temperature aad steam pressure, depending on other reactivity changes oc-curriag. If the reactor is in manual control, no compensation for reactivity changes will be available from the automatic control system. Ia the absence of aay other effects, loss of control rod drive supply water will be annunciated and due to the long-term nature of the effects of this event, sufficient time will be available for the operator to initiate a manual reactor scram.

If valves fail closed, feedwater pump minimum recirculation requirement may not be met, causing feedwater pump degradation at low feedwater flow levels.

h. Feedwater (FWS 6-1)

1) 2FWS-HVXI13) 2FWS-HVY113, 2FWS-SOVX113) 2FWS-SOVY113 I

I adk Failure Effect:

~s Vt If the low energy cleanup valves fail open during normal plant operation, no effect 'will result unless 2FWS-MOV112 fails open due to failure of pressure switch 2FWS-PS112 or 2FWS-PS113 and inadvertent operator action to open the MOV112 from the main control room. This will divert feed-water flow to the main condenser and not to the reactor.

2) 2FWS"HVX111, 2FWS-HVY111) 2FWS-HVZ]11 Failure Effect:

If the above valves open during normal plant operation, no effect will result unless 2FWS-MOV110 is inadvertently open. 2FWS-MOV110 is manually controlled from the main control room, and if this valve is inadvertently opened then a significant 'feedwater flow will be diverted to main condenser and not to the reactor.

1) 2HDL-LT2A, 2HDL-LT2B, 2HDL-LT2C 0131"12177-HC3 D-C-20

Failure Effect:

If the above instrumentation fails the normal drain. valves 2HDL-LV2A, 2HDL-LV2B, and 2HDL"LV2C in the open position, then a partial loss of second point low pressure feedwater heating will result.

2) 2HDL-LS22A) 2HDL-LS22B) 2HDL"LS22C ) 2HDL"LT22A )

2HDL-LT22B, 2HDL-LT22C Failure Effect:

If the above instrumentation fails the emergency level control valves 2HDL-LV22A, 2HDL-LV22B, and 2HDL-LV22C in the open position, second point low pressure feedwater heating from heaters 2CNM-E2A, 2CNM-E2B, and 2CNM-E2C will be reduced or lost due to the draining of the drain re-ceiver tanks 2HDL-TK2A, TK2B and TK2C to the condenser.

If any or all of the above valves fail closed, second po'int low pressure feedwater heating may also be reduced or lost, due to the backup of water from the tanks to the heaters.

3) 2HDL LS7A) 2HDL LS7B ) 2HDL LS7C ) 2HDL LS8A) 2HDL LS8B )

2HDL-LS8C Failure Effect:

If the above level switches fail such that high level in the first and second point heaters is not sensed, a high level condition in the first and second point feedwater heaters will result. This can eventually cause water in-duction into the low-pressure turbines, leading to turbine vibration and turbine trip.,

If the level switches fail such that two or more of the associated low-pressure feedwater strings are isolated and the associated heater drain pumps stop, a total loss of feedwater to the reactor may occur as a result.

If only one of the low-pressure feedwater heater strings is isolated, the other two strings will pick up the flow.

If this valve fails close, main steam supply to moisture separator reheater 2MSS-E1B will be shut off. This wi:ll cause poor quality reheat steam to the low pressure tur-bines, which may lead to turbine vibrations and trip.

k. Turbine Generator Gland Seal and Exhaust (TME 16-1) 2TME-AOV121, 2TME-SOV121, 2TME"PV122 Failure Effect:

If either of these valves fail close, then the main steam back-up supply to the turbine generator gland seal and exhaust sys-tem will be lost. Normal supply is from the clean steam reboilers 2TME-E1A or 2TME-EIB. 'If this supply is lost, con-denser vacuum will eventually be lost.

2. The following is the list of nonsafety-related control components that are affected by a high energy line break on any of the lines listed in Item 1. The consequence of failure of each control compo-nent is analyzed. Refer to Appendix B for the function of individu-.

al components.

a~ Condenser Air Removal (ARC 5-1)

1) 2ARC FS8A ) 2ARC FS8B ) 2ARC SOV1 8A j 2ARC SOV 1 8B Failure Effect Failure of these devices will affect the operation of the condenser air removal pumps or may affect the supply of water to the condenser air removal pump discharge separa-tor tanks. Since the air removal pumps are in service during plant startup only, this event has no significant effect during normal plant operation when air ejectors are in service.

2) 2ARC-AOV105, 2ARC"SOV105 Failure Effect This valve is required to remove air and noncondensable gases during startup. Therefore, failure of this valve in either position 'will not pose any significant effect.

0116-12177-HC3 D-D"14

b. Auxilia Steam (ASS 3-9) 2ASS-AOV147) 2ASS-SOV147) 2ASS-PC107, 2ASS"PC139 Failure Effect If the above pressure 'controllers cause either or both of the pressure control valves (2ASS-PV107 or 2ASS-PV139) to fail close, then the main steam supply to the condenser air removal system may be reduced or lost. If the auxil-iary steam inlet valve to steam jet air ejectors 2ASS-AOV147 also fails close, then the condenser air re-moval backup system is lost. Loss of condenser vacuum will result.

2) 2ASS-PV140, 2ASS-SOV138 Failure Effect If either valve from the auxiliary steam system backup supply fails close, the main steam normal supply pressure control valve 2ASS-PV125, in a different zone (N) from the main steam supply to the preheaters 20FG-E1A and 20FG-E1B, will continue to supply the offgas preheaters.

If both valves fail open, increasing the pressure to the offgas preheaters and therefore increasing the flow to the condenser, the offgas temperature to . the recombiners 20FG-RBNRlA and 20FG-RBNR1B will be elevated.

C~ Turbine Plant Co onent Coolin Water (CCS 9-7) 2CCS-AOV105, 2CCS-SOV105, 2CCS-LS105 Failure Effect If the valve 2CCS-AOV105 fails in closed position at low level in the surge and makeup tank 2CCS-TK1, closed loop cooling water pumps 2CCS-P1A, B, C may trip on low suction pressure causing possible loss of closed loop cooling wa-ter in turbine building which may ultimately cause run-back/trip of turbine or loss of coolant in generator winding.

2) 2CCS-I/P32A, 2CCS-TV32A) 2CCS"I/P32B, 2CCS"TV32B Failure Effect Failure of exciter cooler temperature control valve 2CCS-TV32A and 2CCS-TV32B in closed position will result in exciter alternator cooler high temperature. This will require some operator action.

0116"12177"HC3 D-D-15

3) 2CCS-I/P109, 2CCS-TV109 Failure Effect Failure of hydrogen cooler temperature modulating valve 2CCS-TV109 in closed position will result in loss of cool-ing water to generator hydrogen coolers. This will result in increased generator stator winding temperature. Higher stator winding temperature will result in turbine runback.

4) 2CCS-PS102, 2CCS-PS17A, 2CCS-PS17B, 2CCS"PS17C Failure Effect If any of the above instruments fail, closed loop cooling water pumps 2CCS-P1A, 2CCS-P1B, or 2CCS-P1C may fail to start or fail to trip or may start or trip inadvertently.

If the above reduces the number of turbine building closed loop cooling water pumps in service, a reduction or loss of closed loop cooling will occur. If the above fails to trip the respective pump, then after a period of time the pump or pumps could be damaged and 'cause a reduction or loss of closed loop cooling.

5) 2CCS-I/P104, 2CCS-TV104 Failure Effect If the bypass portion of 2CCS-TV104 fails open bypassing turbine plant component cooling water heat exchangers, this results in higher component cooling water temperature.

6) 2CCS"TV15A) 2CCS-TV15B, 2TMB-TIClA, 2TMB-TIC1B Failure Effect If these valves fail close, cooling to the turbine electrohydraulic fluid control system will be lost. This will have no significant short-term impact.

d. Condensate Demineralizer (CND 4-7) 2CND"AOV333 Failure Effect Failure of 2CND-AOV333 in open or close position', has no signif-icant effect.

0116"12177-HC3 D-D-16

e. Condensate (CNM 4-1) 2CNM-I/P137 Failure Effect Failure of startup bypass valve 2CNM-LV137 in open or close position will have no affect on feedwater pumps.

2) 2CNM-FT114, 2CNM-I/P114 Failure Effect If the failure of the transmitter 2CNM-FT114 leads to the failure of the valve 2CNM-FV114 to open position, reduc-tion of condensate/feedwater flow will result.

3) 2CNM-AOV109, 2CNM-SOV109A, 2CNM-SOV109B.

.Failure Effect If these devices fail, some condensate flow may bypass the condensate polisher. This has no significant short-term effect. If 2CNM-AOV109 is prevented from opening follow-ing turbine trip, however, the requirement for 115 percent feedwater flow to the reactor following turbine trip can-not be met, and initiation of the reactor core isolation cooling system will occur on low reactor ,water level.

4) 2CNM-PS73A, 2CNM-PS73B, 2CNM-PS73C, 2CNM-PS74A, 2CNM PS74B ) 2CNM PS74C ) 2CNM FT68A ) 2CNM FT68B ) 2CNM FT68C Failure Effect Failure of the above instruments will cause the reactor feed pumps to trip, resulting to a total loss of reactor feedwater.

5) 2CNM-PS39A) 2CNM-PS39B, 2CNM"PS39C, 2CNM-PS42A, 2CNM-PS42B, 2CNM"PS42C Failure Effect Failure of any or all of the above instruments during the normal operation will cause the selected standby conden-sate pump to fail to start and also will cause the operat-ing condensate booster pumps to trip resulting in a total loss of reactor feedwater.

6) 2CNM FT38A ) 2CNM I/P38A j 2CNM I/P38B ) 2CNM I/P38C ')

2CNM-FT38B, 2CNM-FT38C 0116-12177 "HC3 D-D-17

Failure Effect If the above instrumentation fails and causes any or all of the condensate booster pump recirculation valves 2CNM-FV38A, 2CNM-FV38B, and 2CNM-FV38C to open, then con-densate flow will be decreased.

If the above instrumentation fails any or all of the con<<

densate 'booster pump 'recirculation valves close, then the booster pumps may become subject to a lack of flow and be damaged if the condensate demand diminishes.

Condensate Booster P Lube Oil S stem (CNO 4-10) 2CNO-PS1A, 2CNO-PS1B, 2CNO-PSIC, 2CNO-PS2A) 2CNO-PS2B, 2CNO-PS2C) 2CNO-PS9A, 2CNO-PS9B, 2CNO-PS9C Failure Effect Failure of the above condensate booster pump pressure switches may cause a trip of the running condensate booster pumps or associated electric lube oil pumps, and/or may block automatic start of the standby condensate booster pump. This will result in partial or total loss of feedwater flow to the reactor.

g~ Condensate Makeu /Drawoff (CNS 4-3)

1) 2CNS-LV103 Failure Effect Failure of the valve 2CNS-LV103 in closed position will result in reduced condensate inventory from normal conden-sate makeup system to the main condenser.

2) . 2CNS-LIC103, 2CNS-LIC105 ) 2CNS-LSL103 Failure Effect If the failure of the above instruments drives the valves 2CNS-LV103 and 2CNS-AOV304 in closed position and 2CNS-JV105 in open position, condensate inventory in the condenser will be affected, which may cause reduction in feedwater in the reactor.

h. Moisture Se arator Vents and Drains (DSM 32-7)

1) 2DSM I/PX75A ) 2DSM I/PY75A ) 2DSM I/PZ75A ) 2DSM I/PX75B )

2DSM-I/PY75B, 2DSM-I/PZ75B 0116-12177-HC3 D-D-18

Failure Effect If the instrumentation fails any or all valves 2DSM-LVX75A) 2DSM"LVY75A) 2DSM-LVZ75A) 2DSM"LVX75B, 2DSM-LVY75B, or 2DSM-LVZ75B in closed position, partial loss of feedwater heating at fourth pointer will result.

2) 2DSM-I/P78B) 2DSM-LT78B Failure Effect If 2DSM"LT78B fails 2DSM-LV78B in open position, conden-sate from 2DSM-TK4B will drain from 2DSM-TK4B to main con-denser, causing partial loss of feedwater heating at fourth point heater 2CNM-E4A, E4B, or E4C.

3) 2DSM-I/P78A, 2DSM-LT78A Failure Effect Same as above item 2) except for A valves and tank.

4) 2DSM-LT75B Failure Effect If this transmitter fails causing closure of control valves 2DSM-LVX75B, 2DSM-LVY75B, and 2DSM-LVZ75B which supply heating to the fourth point feedwater heaters 2CNM-E4A, 2CNM-E4B, and 2CNM-E4C from moisture separator drain receiver 2CNM-TK4B, partial loss of fourth point feedwater heating will result.

5) 2DSM-LT75A Failure Effect Same as above item 4) except for A loop.

6) 2DSM-LS70A, 2DSM-LS70B Failure Effect If the above level switches fail in such a direction as to signal false high level in the moisture separator reheaters, a turbine trip will result.

If the level switches fail such that a high level in the moisture separator reheater is not detected, water induc-tion into the high pressure turbine may result. This may cause excessive turbine vibration leading to turbine trip.

i. Moisture Se arator Reheater Vents and Drains (DSR 32-6) 2DSR-I/PX65A, 2DSR-I/PY65A, 2DSR-I/PZ65A) 2DSR-I/PX65B) 2DSR-I/PY65B) 2DSR-I/PZ65B Failure Effect If the instrumentation fails any or all valves, 2DSR-LVX65A, 2DSR-LVY65A, 2DSR-LVZ65A, 2DSR-LVX65B, 2DSR-LVY65B, or 2DSR-LVZ65B in closed position partial loss of feedwater heating at sixth point heater results.

2) 2DSR-PT78A, 2DSR-PT78B Failure Effect If these instruments fail and cause scavenging steam valve 2DSR"MOV68A (2DSR-MOV68B) to fail in the close position, then sixth point feedwater heating will be reduced.

3) 2DSR-I/P68A) 2DSR-I/P68B, 2DSR-LT68A, 2DSR-LT68B Failure Effect If this instrumentation causes failure of 2DSR-LV68A (2DSR-LV68B) in the open position, condensate from 2DSR-TK6A (2DSR-TK6B) will drain to the main condenser, resulting in partial loss of heating at sixth point heat-ers 2FWS-E6A, 2FWS-E6B, and 2FWS-E6C.

4) 2DSR-LT65A, 2DSR-LT65B Failure Effect Failure of these devices which cause closure of control valves 2DSR-LVX65A (2DSR-LVX65B), and 2DSR-LVY65A (2DSR-LVY65B) which supply heating to the sixth point feedwater heaters 2FWS-E6A, 2FWS-E6B, 2FWS-E6C from mois-ture separator reheater drain receiver tank 2DSR-TK6A (2DSR-TK6B), will result in reduction of sixth point feed-water heating.

Extraction Steam (ESS, 3-4) 2ESS-PS110) 2ESS-PS115 Failure Effect Failure of these instruments will fail control valve 2ESS-STV105 either open or close. This will affect the backup steam supply to building heating intermediate heat exchangers 2HVH-E1A and 2HVH-ElB. No significant impact on the system will occur.

0116-12177-HC3 D-D-20

2) 2ESS-PS112, 2ESS-PS116 Failure Effect 0 Inadvertent cause failure of 2ESS-PS1i2 and/or 2ESS-PS116 may failure of 2ESS-STV104 in closed position which will stop extraction steam to clean steam reboilers. Clean steam reboiler has alternate sources of steam available from main steam or auxiliary steam. In the event both main steam isolation valve 2ASS-STV112 and auxiliary steam supply. valve 2ASS-PV146 are closed, turbine generator gland sealing steam would be lost. This may result in gradual loss of condenser vacuum.

k. FDW P and Drive Lube Oil (FWL 7-3) 2FWL-PS1A, 2FWL-PS1B, 2FWL-PS1C, 2FWL-PS2A, 2FWL-PS2B, 2FWL-PS2C Failure Effect Instrumentation failure may cause either inadvertent feedwater pump trip or failure to trip feedwater pump on extreme low lube oil pressure.

1. FDW Seal and Leakoff (FQP 6-4) 2FWP-PCV5A) 2FWP"PDIC5A) 2FWP-PDK5A) 2FWP"PDTSA, 2FWP"PCV5B, I

2FWP PD C5B ) 2FWP PDKSB ) 2FWP PDTSB ) 2FWP PCV5C ) I 2FWP PD CSC )

2FWP-PDK5C) 2FWP-PDTSC, 2FWP-PS5A, 2FWP-PS5C Failure Effect Failure of the above instrument will cause loss of reactor feedwater pumps bearing seal water. This event has no signifi-

'cant effect.

m. FDW P Recirculation (FWR 6-3) 2FWR-I/P2A, 2FWR-I/P2B, 2FWR-I/P2C Failure Effect Failure of these instruments causes recirculation valve 2FWR-FV2A, B, C to open, thus reducing the feedwater flow to the reactor.

If failure of these instruments causes the recirculation valve 2FWR-FV2A, B, C to close, feedwater pump minimum recirculation requirement may not be met.

0116-12177-HC3 D"D"21

n. Feedwater (FWS 6-1) 2FWS-I/PX113, 2FWS-I/PY113, 2FWS-PS112, 2FWS"PS113 Failure Effect Failure of the above instrumentation can cause low energy cleanup valves 2FWS-HVX113 and 2FWS-HVY113 to open. Fail-ure of 2FWS-HVX113 or 2FWS-HVY113 in open position has no effect during normal plant operation unless 2FWS-MOV112 fails open due to failure of pressure switch 2FWS-PS112 or 2FWS-PS113 and inadvertent operator action to open 2FWS>>MOV112 from main control room. This will divert feedwater flow to the main condenser and not to the reactor.

2) 2FWS-I/PX111, 2FWS-I/PY111, 2FWS-I/PZ111 Failure Effect If the above instruments cause high energy feedwater cycle cleanup control valves 2FWS-HVXlll, 2FWS-HVY111, and 2FWS-HVZlll to open during normal plant operation, no ef-fect will result unless the 2FWS-MOV110 in zone C is inad-vertently open. If the MOV which is manually controlled from the main control is open, then a significant amount of feedwater flow will be diverted to the condenser and not to the reactor.

3) 2FWS"HV105, 2FWS-SOV105 Failure Effect If this instrument fails in the open position, insignifi-cant amount of feedwater to the reactor vessel will 'be diverted to the condenser. This valve is on 3/4 in. line.

4) 2FWS LVlOA) 2FWS LV10B) 2FWS LV10C ) 2FWS FT1A) 2FWS FTlB Failure Effect If these valves fail open, in the worst, case 'a reactor vessel high level will result, causing reactor scram, tur-bine trip, and main feedwater pump trip. If one or. more of these valves fail closed, a decrease in reactor. water level may occur. Recirculation pump runback will occur at level 4, and a reactor scram and turbine trip will occur if reactor vessel level 3 is reached. Similar sequence will occur upon failure of the above flow transmitters which provide signals to the feedwater level control system.

0116-12177'-HC3 D-D"22

5) 2FWS-LV55A Failure Effect This valve is normally closed. If the valve were to open there would be no effect since the feedwater control system would close 2FWS-LVlOA (C33-FOOlA) to maintain proper flow.

0 Generator Stator Coolin Water (GMC 16-8) 2GMC-TVIOI, 2GMC-PDC102 Failure Effect Failure of the temperature control valve may cause the stator cooling water to bypass the coolers resulting in higher inlet/outlet stator coolant temperature which could result in reduction of generator output.

If the valve 2GMC-PDV102 fails in closed position causing total loss of generator coolant, turbine runback/trip will occur.

2) 2GMC-FS140, 2GMC-FV127, 2GMC-FV128, 2GMC-PDV102) 2GMC-PNL141, 'GMC-PS103, 2GMC"PS105) 2GMC"PS139) 2GMC-PS6A, 2GMC-PS6B) 2GMC-SOV130, 2GMC-TIC101, 2GMC"TS109 Failure Effect Failure of the above devices may result in the loss of the generator stator cooling water system. This will result in turbine runback and may result in turbine trip if gen-erator armature current is not reduced after 3.5 minutes.

P ~ Generator H dro en and CO (GMH 16-7) 2GMH-AOV162) 2GMH-SOV162) 2GMH-PS174 Failure Effect If this valve fails open, the generator hydrogen supply will be vented to atmosphere and eventually generator hy-drogen pressure and cooling will be lost reducing genera-tor output.

2) 2GMH AOV1 19 ) 2GMH SOV1 19 ) 2GMH PCV1 1 1 ) 2GMH PV1 17 2GMH-PT117 0116-12177"HC3 D-D-23

Failure Effect If either valve fails close, the generator hydrogen supply will not be available for replenishing generator hydrogen pressure lost through control of these valves. However, the operator can bypass these valves manually.

3) 2GMH"SOU173 Failure Effect This valve is normally deenergized (closed) and is ener-gized manually by operator only when the generator'as analyzer is in standby. Failure of this valve in the, open position would result in a very small loss of hydrogen sample gas to atmosphere within the makeup capability of the hydrogen storage system. Therefore, failure has no effect.

Generator Leads Coolin (GML 16-10) 2GML-FS1A) 2GML-FS1B Failure Effect If these instruments fail indicating low air flow after a time delay, the generator leads cooling fans 2GML-FN1A, -FN1B will be stopped causing"a loss of. generator lead cooling.

Generator Seal Oil GMO 16-6)

1) 2GMO-PS102 Failure Effect If this pressure switch should fail, such that it did not sense main seal oil pressure low and did not start the emergency seal oil pump 2GMO-P2, the emergency seal oil pump would not start.

Main Steam (MSS 3-1)

1) 2MSS-PT103 Failure Effect Failure of this pressure transmitter can result in the opening of numerous main and auxiliary startup drain lines to the main condenser. This will cause bypassing of steam to the main condenser during normal operation, but will have no significant effect on reactor parameters.

2) 2MSS-PT104

.Failure Effect Failure of this device may result in the opening of main steam line startup drain valves 2MSS-AOV85A through D.

The resulting bypassed steam to the main condenser will have no significant effect on reactor parameters. Also, failure of this device may prevent condensate demineraliz-er bypass valve 2CNM-AOV109 from opening following 'turbine trip.. In this event, the requirement for 115 percent feedwater flow to the reactor following turbine trip can-not be met, and initiation of the reactor core isolation cooling system will occur on low reactor water level. If turbine trip does not occur, partial .loss of condensate polishing will occur. This has no significant effect.

1) 2TMB-PS130 Failure Effect Failure of this device which causes opening of 2MSS-MOV21A, 2MSS-MOV21B, 2MSS-MOV21C, and 2MSS-MOV21C results in bypassing an insignificant amount of main steam to the main condenser through a 2-inch line.

Failure of this device may also cause misoperation of 2DSR-AOV82A) 2DSR-AOV82B) 2DSR-AOV83A) 2DSR"AOV83B, 2DSR"AOV84A, 2DSR-AOV84B, 2DTM-AOV105) 2DTM-AOV166, 2MSS-AOV191, 2MSS-AOV194, 2MSS-AOV203, 2MSS-AOV205, and/or 2MSS-AOV209 which'esults in an insignificant impact.

3. Combined Effect a ~ A break in the condenser air removal high energy line in this zone (Item l.a.l) will result in loss of main condenser offgas treatment and gaseous release in, the turbine building. This event is bounded by FSAR Section 15.7 analyses. Upon detection of turbine building high radiation, due to potential loss of offgas system, the operator should manually isolate the offgas "

system and scram the reactor.

Failure of control components in this zone can result in par-tial or total loss of feedwater flow to the reactor. This will 0116-12177-HC3 D"D-27

lead to reactor, low water level with subsequent scram and ini-tiation of reactor core isolation cooling. This event is bounded by FSAR Section 15.2.7 analyses. If the failure affects components in the feedwater level control system, a high reactor water level may occur with subsequent reactor scram; turbine trip, and feedwater pump trip. This event is bounded by FSAR Section 15.1.2 analyses.

If the reactor is operating at 100 percent power at the time the operator initiates a manual scram due to loss of offgas, the condensate demineralizer bypass valve (2CNM-AOV109) instru-mentation may cause the valve not to open. In this case, the requirement to attain 115 percent feedwater flow after turbine trip may not be met. Therefore, a normal post-trip transient will not occur. Instead,. reactor vessel level will decrease and the reactor core isolation cooling system will initiate.

This event is bounded, however, by FSAR Section 15.6.6 analyses.

Failure of certain other control components in this zone (Items 2.h.l through 2.h.5, 2.i.l through 2.i.4) may result in partial loss of feedwater heating. These failures may include partial loss from the fifth and sixth point feedwater heaters affecting as many as three heater strings. Failure of other control components in this zone (Item 2.t) may result in par-tial loss of feedwater heating from second and third point heater drain coolers and fifth point heaters in all three heater strings and in only one of three fourth point heaters.

This event is bounded by FSAR Section 15.1.1 analysis. If sub-sequent turbine trip occurs due to failure of other control components (Item 2.h.6) or due to manual action by the operator to scram on loss of offgas, the trip may occur at a reactor power level elevated from the initial operating value due to the loss of feedwater heating. In this event, the reactor may experience a change in critical power ratio greater than that described in the unacceptable results of moderate frequency (anticipated operational transients) of FSAR Section 15.1.1.

See Section 3.0 for further discussion.

Several other events which may occur as a result of control component failure may lead to turbine runback or operator ac-tion to reduce turbine load. This is a less severe transient than those discussed, and provides a more conservative initial condition for any other subsequent events which may occur.

b. 1) A break in the auxiliary steam high energy lines in this zone (Items 1.b.l, 1.b.3, and 1.b.4) will result in loss of offgas treatment capability or reduction in treatment efficiency which will ultimately lead to system shutdown and manual reactor scram by the 'operator. This event is bounded by FSAR Section 15.7 analyses.

c~ A break in the auxiliary condensate high energy lines in this zone (Item 1.c.l) will result in a loss of main con-denser vacuum. This event is bounded by FSAR Section 15.2.5 analyses. For analysis of control compo-nent failures, refer to Item 3.a.

2) A break in the auxiliary condensate high energy lines in this zone (Items 1.c.2, 1.c.3, and 1.c.4) will cause a parti'al loss of condensate, which will have no significant short-term effect. This event may also result in a par-tial loss of feedwater heating at third point feedwater heaters., which is bounded by FSAR Section 15.1.1 analyses.

For analysis of control component failures, refer to Item 3.a above.

A break in the condensate high energy line in this zone (Item d.l through d.5, d.8) will result in total loss of feedwater flow. This event is bounded by FSAR Section 15.6.6 analyses (feedwater break outside con-tainment). Control component failure does not exacerbate this event.

2) A break in the condensate high energy lines in this zone (Item 1.d.8, 1.d.9, and '1.d.10) will result in loss of condensate inventory. If the rate of such loss exceeds the makeup capability of the condensate makeup system, the result will be a total loss of condensate and feedwater flow due to condensate or feedwater pump suction pressure trip. This event is bounded by FSAR Section 15.2.7 ana-lyses. It should be noted that Item 1.d.8 will also cause a loss of the condensate supply to the control rod drives, which will prevent normal control motion. This has no significant short-term effect; refer to Appendix D, Zone B, Item 3.e.2 for a detailed analysis of longer-term effects.

For analysis of control component failures, refer to Item 3.a above.

3) A break in the condensate high energy line in this zone (Item 1.d.7) will cause a loss of condensate to the tur-bine generator hood spray temperature control valve 2CNM"TV121. Since hood spray is required primarily during startup and low load, loss of hood sprays during normal operation will have no significant effect on the turbine.

A partial loss of condensate inventory will 'occur, howev-er; refer to Item 3.d.2 for analysis of this event.

0116-12177-HC3 D-D"29

4) A break in the condensate high-energy lines in this zone (Item 1.d.6, 1.d.11) will cause loss of sealing water to the condensate and/or feedwater pump seals. This may cause loss of pump suction pressure and pump trip, result-ing in a loss of feedwater. This event is bounded by FSAR Section 15.2.7 analyses. For a discussion of control com-ponent failures, refer to Item 3.a.

5) A break in the condensate high-'energy line in this zone (Item 1.d.10) results in condensate to turbine generator gland seal and exhaust reboiler, causing a loss of turbine generator gland seal and exhaust steam and loss of condensate inventory.

2. The following is the list of nonsafety-related control components that are affected by a high energy line break on any of the lines listed in Xtem 1. The consequence of failure of each control compo-nent is analyzed. Refer to Appendix B for 'the function of individu-al components.

Additionally, a high energy line break in this zone will also result in failure of control components in Zone D. The significant conse-quences of such a failure have been integrated into the analysis by referring to the appropriate "Failure Effect" from the above-listed zone(s) in the "Combined Effect" section of this zone.

a. Condensate (CNM 4-1 2CNM HV5 lA) 2CNM SOV5 1A ) 2CNM HV52A) 2CNM SOV52A j 2CNM HV56A )

Failure of the above valves. has no significant effect.

b. Moisture Se arator Vents and Drains (DSM 32-7) 2DSM-LVX75A, 2DSM-SOVX75A, 2DSM-LVX75B, 2DSM-SOVX75B Failure Effect Failure of the above valves to. closed position will cause high water level in the moisture separator drain receiver 2DSM-TK4A, B resulting in dumping the drains to the condenser through the valve 2DSM-LV78A, B, thus causing partial loss of feedwater heating in the fourth point heater 2CNM-E4A.

c ~ Moisture Se arator Reheater Vents and Drains (DSR 32-6)

1) 2DSR-AOV81A, 2DSR"SOV81A 0120-12177-HC3 D-F-12

Failure Effect The above valve is intended to operate only when the tur-bine is tripped; therefore, failure of the valve at that time will have no effect on reactor parameters.

If the valve fails to close, position during the normal reactor operation, partial loss of feedwater heating will result in the sixth point heater 2FWS-E6A.

2) 2DSR LVX65A) 2DSR SOVX65A ) 2DSR LVX65B) 2DSR SOVX65B Failure Effect Failure of the above valves to closed position will cause high water level in the reheater drain receiver 2DSR-TK6A, B, resulting in dumping the drains to the condenser through the valve 2DSR-LV68A, B, thus causing partial loss of feedwater heating in the sixth point heater 2FWS-E6A.

d. Feedwater (FWS 6-1) 2FWS-HV42A) 2FWS-SOV42A) 2FWS-HV43A, 2FWS-SOV43A Failure Effect Failure of any or all of the above valves has no significant effect.

e. Hi h Pressure Feedwater Heater Drain (HDH 6-6) 2HDH-LV6A) 2HDH-SOV6A, 2HDH-LT6A, 2HDH LT26A ) 2HDH LS7A )

2HDH-LS26A Failure Effect If 2HDH-LV6A fails closed as a failure of instrumentation, par-tial heating of condensate at fifth point heater 2CNM-ESA will be lost.

If 2HDH-LT26A or LS26A fails, thereby signaling high level in sixth point heater 2FWS-E6A, thereby opening 2HDH-LV26A to drain the heater to condenser, this will bypass the heater drain to the fifth point heater 2CNM-ESA resulting in loss of partial heating of condensate at fifth point heater.

2HDH-LS26A failure will also close 2HDH-LV26A resulting in loss of feedwater heating at sixth point heater 2FWS-E6A.

If 2HDH-LS7A fails, thereby signaling extreme high level in sixth point heater 2FWS-E6A, sixth point extraction steam iso-lation valve 2ESS-MOV3A and nonreturn valve 2ESS-NRV34A will close. This will result in loss of feedwater heating at sixth point heater 2FWS-E6A.

0120-12177"HC3 D-F-13

f. Low Pressure Feedwater Heater Drain (HDL 4-2) 2HDL-LV4A Failure Effect If the valve 2HDL-LV4A fails in open position, fourth point heater low level switch 2HDL-LS14A will eventually trip the heater drain pump 2HDL-P1A. If the valve fails in closed position the same result will occur without the heater drain pump trip.

2) 2HDL-LV5A, 2HDL-SOV5A Failure Effect Failure of the above valve in the closed position will cause bypassing the fourth point heater 2CNM-E4A resulting .

in partial loss of feedwater heating.

3) 2HDL-LT3A, 2HDL-LS9A) 2HDL-LT23A, 2HDL"LS23A Failure Effect If 2HDL-LT3A, 2HDL-LT23A, and 2HDL-LS23A signal in such a way that the third point heater drain valves 2HDL-LV3A and 2HDL-LV23A fail in closed position, it may cause flooding of the drain cooler and the third point heater, resulting in partial loss of feedwater heating.

If level switch 2HDL-IS9A causes inadvertent closure of extraction steam isolation valve 2ESS-MOV15A, loss of feedwater heatin'g in .the third point heater will result.

4) 2HDL-FV35A) 2HDL-SOVX35A, 2HDL-SOVY35A Failure Effect If the above valve fails in open position, heater drain pump discharge flow to the condensate system will be re-duced, thus causing partial loss of feedwater.

If the valve heater drain fails in closed position, it may result in pump overheating in low flow condition..

5) 2HDL-LT4A (tubing), 2HDL-LS10A, 2HDL-LT24A, 2HDL-LS24A, 2HDL-LS14A Failure Effect If 2HDL-LT4A causes 2HDL-LV4A to fail in closed position, partial loss of feedwater will result. Failure of 0120-12177-HC3 D-F-14

2HDI-LV24A to open position due to the failure of 2HDL-LT24A and 2HDL-LS24A will. also result in a partial loss of feedwater. Failure of 2HDL-LS14A may cause heater drain pump 2HDL-P1A to trip, resulting in partial loss of feedwater.

Failure of 2HDL-LS10A may cause closing of extraction

'te'am valve 2ESS-MOV22A, resulting in loss of feedwater heating in fourth point heater 2CHM-E4A.

6) 2HDL-LTSA, 2HDL-LS11A, 2HDL-LT25A) 2HDL-LS25A Failure Effect If 2HDL-LTSA signals in such a way that fifth point heater drain valve 2HDL-LVSA fails closed bypassing the fourth point heater 2HDL-E4A resulting in partial loss of feed-water heating.

If 2HDL-LT25A or 2HDL-LS25A fails the fifth point heater drain bypass valve 2HDL-LV25A in open position, the fourth point heater 2HDL-E4A is bypassed, resulting in partial loss of feedwater heating.

If 2HDL-LSllA fails, thereby signaling extreme high level in fifth point heater 2HDL-ESA, fifth point heater extrac-tion steam isolation valve 2ESS-MOV28A will close, result-ing in loss of feedwater heating at fifth point heater 2CNM-E5A.

2) 2SVH"HV31A, 2SVH-HV44A, 2SVH"SOV31A, 2SVH"SOV44A Failure Effect If these shell vent valves fail open and cause venting of third and fourth point heaters (A) to the condenser, no significant impact results.

3. Combined Effects a ~ A break in auxiliary condensate high energy line in this zone will result in a loss of feedwater heating in the third point heaters. Loss of feedwater heating event is bounded by FSAR Section 15.1.1 analyses.

The failure of control components [2.b, 2.c.2), 2.e, 2.f.1),

2.f.2), 2..f.3), or 2.f.6)] in this zone may also result in fur-ther reduction in feedwater heating, an event bounded by FSAR Section 15.1.1 analyses. In addition to this, failure of the control components [2.f.4) or 2.f.5)) may result in loss of feedwater. I,oss of feedwater event. is bounded by FSAR Section 15.2.7 analyses.

4) Loss of condenser vacuum (Zone D), an event bounded by FSAR Section 15.2.5 analyses.

5) Feedwater controller failure - maximum demand (Zone D), an event bounded by FSAR Section 15.1.2 analyses.

If the turbine trip occurs at a reactor power level ele-vated from initial operating value due to the loss of feedwater heating (caused by the failure of control compo-nents in this zone or zone D), the reactor may experience a change in critical power ratio greater than that de-scribed in the unacceptable results of incidents of moder-ate frequency anticipated operational transients of FSAR Chapter 15.

2. The following is the list of nonsafety-related control components that are affected by a high energy line break on any of the lines listed in Item 1. The consequence of failure of each control compo-nent is analyzed.

Additionally, a high energy line break in this zone will also result in failure of control components in Zone D. The significant conse-quences of such a failure have been integrated into the analysis by referring to the appropriate Failure Effect from the above listed zones in'he Combined Effect section of this zone.

a. Condensate (CNM 4-1)

1) 2CNM-AOV101, 2CNM-SOV101A, 2CNM"SOV101B) 2CNM-SOV101C, 2CNM-SOVI01D Failure Effect Inadvertent opening of 2CNM-AOV101 will cause the feed-water to bypass the LP heater string resulting in loss of feedwater heating.

If the valve 2CNM-AOV101 fails to open in the event of feedwater tube failure in the first and second point heat-ers, possible water induction into the turbine may ulti-mately cause turbine trip due to excessive vibration.

2) 2CNM-HV56A, 2CNM-SOV56B) 2CNM-HV57B, 2CNM"SOV57B, 2CNM-HV58B, 2CNM-SOV58B) 2CNM-HV59B) 2CNM-SOV59B, 2CNM"HV60B, 2CNM-SOV60Q) 2CNM-HV51B, 2CNM"SOU51B, 2CNM-HV52B) 2CNM-SOV52B Failure Effect Failure of the above valves has no significant effect.

0113-12177-HC3 D-G-14

3) 2CNM-LV137 Failure Effect Failure of the above valve either in the close or open position will pose no significant effect on feedwater pumps

b. Moisture Se arator Vents and Drains (DSM 32-7) 2DSM-LVY75A, 2DSM-SOVY75A, 2DSM-LVY75B, 2DSM-SOVY75B Failure Effect Failure of the above valves to closed position will cause high water level in the moisture separator drain receiver 2DSM-TK4A, B resulting in dumping the drains to the condenser through the valve 2DSM-LV78A, B thus causing partial loss of feedwater heating in the fourth point heater 2CNM-E4B.

c~ Moisture Se arator Reheater Vents and Drains (DSR 32-6)

1) 2DSR"SOVY65A) 2DSR-LVY65A, 2DSR-SOVY65B, 2DSR-LVY65B Failure Effect If the solenoid valve, 2DSR-SOVZ65A (or 65B) fails the

.0 control valve 2DSR-LVZ65A (or 65B) in close position, par-tial loss of feedwater heating at the sixth point heater 2FWS-E6B will result.

2) 2DSR-AOV81B) 2DSR-SOV81B Failure Effect If the valve fails to closed position during the normal

.reactor operation, partial loss of feedwater heating will result in the sixth point heater 2FWS-E6B.

If 2HDH-LV6B fails closed as a failure of instrumentation, partial heating of condensate at fifth point heater 2CNM-E5B will be lost.

If 2HDH-LT26B or LS26B fails, thereby signaling high level in sixth point heateq 2FWS-E6B, thereby opening 2HDH-LV26B to drain the heater to condenser. This will bypass the heater drain to the fifth point heater 2CNM-ESB, resulting in loss of partial heating of condensate at fifth point heater. 2HDH-LS26B failure will also close 2HDH-LV26B resulting in partial loss of feedwater heating at sixth point heater 2FWS-E6B.

If 2HDH-LS7B fails, thereby signaling extreme high level in sixth point heater 2FWS-E6B, sixth point extraction steam isolation valve 2ESS-MOV3B and nonreturn valve 2ESS-NRV34B will close. This will result in loss of feedwater heating at sixth point heater 2FWS-E6B.

2) 2HDH-SOV29B Failure Effect Failure of the valve 2HDH-SOV298 in the close or open po-sition has no significant effect.

f. Iow Pressure Feedwater Heater Drain (HDL 4-2) 2HDL-FV35B, 2HDL-SOVX35B) 2HDL>>SOVY35B Failure Effect If the above valve fails in open position, heater drain pump discharge flow to the condensate system will be re-duced, thus causing partial loss of feedwater.

If the valve fails in closed position, it may result in heater drain pump overheating in low flow condition.

2) 2HDL-LT4B (tubing), 2HDL-LS10B) 2HDL-LT24B, 2HDL-LS24B) 2HDL-LS14B Failure Effect If 2HDL-LT4B causes 2HDI-LV4B to fail in closed position, partial loss of. feedwater will result. Failure of 2HDL-LV24B to open position 'ue to the failure of 2HDL-LT24B and 2HDL-LS24B will also result in a partial loss, of feedwater. Failure of 2HDL-LS14B may cause heater drain pump 2HDL-P1B to trip resulting in partial loss of feedwater.

0113-12177-HC3 D-G-16

Failure of 2HDL-ISlOB may cause closing of extraction steam valve 2ESS-MOV22B resulting in loss of feedwater heating in fourth point heater 2CNM-E4B.

3) 2HDL-LV4B Failure Effect If the valve 2HDL-LV4B fails in open position, fourth point heater low level switch 2HDL-LS14B will eventually trip the heater drain pump 2HDL-P1B. If the valve fails, in closed position the same result will occur without the heater drain pump trip.

4) 2HDL-LT3B) 2HDL-LS9B, 2HDL-LT23B, 2HDL-LS23B.

Failure Effect If 2HDL-LT3B, 2HDL-LT23B, and 2HDL-IS23B signals in such a way that the third point heater drain valves 2HDL-LV3B and 2HDL-LV23B fail in closed position, it may cause flooding in the drain cooler and the third point heater resulting in partial loss of feedwater heating.

If the level switch 2HDL-LS9B causes inadvertent closure of the extraction steam isolation valve 2ESS-MOV15B, loss of feedwater heating in the third point heater will result.

2HDL-LS25B Failure Effect If 2HDL-LTSB signals in such a way that fifth point heater drain valve 2HDL-LV5B fails closed bypassing the fourth point heater 2HDL-E4B resulting in partial loss of feed-water heating.

If 2HDL-LT25B or 2HDL-LS25B fails the fifth point heater drain bypass valve 2HDL-LV25B in open position, the fourth point heater 2HDL-E4B is bypassed resulting in partial loss of feedwater heating.

If 2HDL-LS11B fails thereby signaling extreme high level in fifth point heater 2HDL-E5B, fifth point heater extrac-tion steam isolation valve 2ESS-MOV28B will close, result-ing in loss of feedwater heating at fifth point heater 2CNM-E5B.

If 2HDH-LT26C or LS26C fails, thereby signaling high level in sixth point heater 2FWS-E6C, 2HDH-'LV26C will open to drain the heater to the condenser. This will bypass the heater drain to the fifth point heater 2CNM-E5C, result'ing in 'oss 'of partial heating of condensate at the fifth point heater.

Failure of level switch 2HDH-IS26C will also close 2HDH-LV26C, resulting in loss of feedwater heating at the sixth point heater 2FWS-E6C.

If level switch 2HDH-LS7C fails, thereby signaling extreme high level in sixth point heater 2FWS-E6C, sixth point extraction steam isolation valve 2ESS-MOV3C and nonreturn valve 2ESS-NRV34C will close. This will result in loss of feedwater heating at sixth point heater 2FWS-E6C.

f. Iow Pressure Feedwater Heater Drains (HDL 4-2) 2HDL-FV35C, 2HDL-SOVX35C, and 2HDL-SOVY35C Failure Effect If the above valve fails in the open position, heater drain pump discharge flow to the condensate system will be reduced, thus causing partial loss of feedwater. If the valve fails in the closed position, it may result in heat-er drain pump overheating due to a low flow condition.

2HDL-LT3C, 2HDL-LS9C, 2HDL-LT23C, and 2HQL-LS23C Failure Effect If 2HDL-LT3C, 2HDL-LT23C, and 2HDL-LS23C provide a signal such that the third point heater drain valves 2HDL-LV3C and 2HDL-LV23C fail in the closed position, it may cause.

3) 2HDL-LT4C (tubing), 2HDL-LS10C, 2HDL-LT24C, 2HDL-LS24C, and 2HDL-LS14C Failure Effect If 2HDL-LT4C causes 2HDL-LV4C to fail in the closed posi-tion, partial loss of feedwater will result. Failure of 2HDL-LV24C to the open position due to the failure of 2HDL-LT24C and 2HDL-LS24C will also result in a partial loss of feedwater. Failure of 2HDL-LS14C may cause heater drain pump 2HDL-P1C to trip, resulting in a partial loss of feedwater.

Failure of 2HDL-LSlOC may cause closure of extraction steam valve 2ESS-MOV22C resulting in loss of feedwater heating in fourth point heater 2CNM-E4C.

4) 2HDL-LT5C, 2HDL-IS11C, 2HDL-LT25C, and 2HDL-IS25C Failure Effect If 2HDL-LTSC provides a signal such that fifth point heat-er drain valve 2HDL-LV5C fails closed, bypassing the fourth point heater 2EDL-E4C, partial loss of feedwater heating will result.

If 2HDL-LT25C or 2HDL-LS25C fails the fifth point heater drain bypass valve 2HDL-LV25C in the open position, the fourth point heater 2HDL-E4C, is bypassed, resulting in partial loss of feedwater heating.

If 2HDL-LS11C fails, thereby signaling extreme high level in fifth point heater 2HDL-E5C, fifth point heater extrac-tion steam isolation valve 2ESS-MOV28C will close, result-ing in loss of feedwater heating at fifth point heater 2CNM-ESC.

5') 2HDL-LV4C Failure Effect If valve 2HDL-LV4C fails in the open position, fourth point heater low level switch 2HDL-LS14C will eventually trip the heater drain pump 2HDL-PlC. If the valve fails in the closed position, the same result will occur except for the heater drain pump trip.

Turbine Plant Co onent Coolin Water (CCS 9-7) 2CCS-TV43A, 2CCS-TV43B Failure Effect Failure of the above valves to the closed position will cause loss of turbine lube oil cooling resulting in higher turbine bearing temperature.

b. Turbine Generator Lube Oil (TML, 16-2)

1) 2TML-PS102, 2TML-SOV114 Failure Effect Failure of this pressure switch or SOV will prevent auto-matic start of the ac motor-driven suction oil pump 2TML-P3, which supplies suction pressure to the main shaft-driven oil pump either during startup or when oil-driven booster pump discharge pressure drops to a pre-determined value.

2) 2TML-PS103, 2TML-PS104, 2TML-SOV115 Failure Effect:

Failure of these pressure switches or valve to allow auto-matic start" of the turning gear oil pump 2TM2-P4 on low pressure has no significant effect when the turbine is not on turning gear. However, this pump also serves as a 0555-12177-HC3 D-R-2

backup to the main shaft-driven oil pump. A dc motor"driven emergency bearing oil pump also is provided in case of failure of both the ac power or turning gear oil pump failure.

3) 2TML-PS105 Failure Effect Failure of this pressure switch will prevent automatic start of the system.

4) 2TML-PS106, 2TML-PS107) 2TML-SOV117, 2TML-SOV118 Failure Effect Failure of these control components will prevent automatic start of the emergency bearing oil pump 2TML-PS. This pump is used as a backup of main shaft oil pump and turn-ing gear oil pump, both of which are used during startup.

Therefore, failure of the pressure switches will not im-pact normal operation of the plant.

I 5) 2TML-PS127 Failure Effect Failure of this pressure switch may cause inadvertent tur-bine trip or the failure to trip the turbine on turbine shaft pump lube oil discharge pressure low.

6) 2TML"PS101, 2TML-SOV116 Failure Effect Failure of these instruments will prevent automatic start of the turning gear piggyback motor. Since this motor is used for startup or turning gear operation only, it will not impact normal operation of the plant.

b. " Turbine Plant Co onent Coolin Water (CCS 9-7) 2CCS-I/P43A, 2CCS-I/P43B Failure Effect Failure of the above instruments may cause turbine closed loop cooler temperature control valves 2CCS-TV-43A and 2CCS-TV43B to fail in &e closed position, resulting in loss of turbine lube oil cooling, thus causing higher turbine bearing temperature.

c. Cold Reheat (CRS 3-2) 2CRS-PT103 Failure Effect Failure of the above instrument may cause inadvertent closure of moisture separation main steam supply valves 2MSS-PV28A, 2MSS-PV28B, 2MSS-PV29A, and 2MSS-PV29B, which can result in reduction of hot reheat steam temperature to low-pressure turbines.

4) 2MSS-PT96B (C12-N054-B), 2MSS-PT96A (C12-N054-A)

Failure Effect Failure of these first stage turbine pressure transmitters would result in loss of the low power set point (LPSP) and low power alarm point (LPAP). This would not affect reactor parameters.

Failure Effect If the above instrumentation fails closed, the condensate source to the clean steam boilers (2TME-E1A, ElB) will be lost.

In addition, there is an alternate source from the main steam sy'tem for gland seal and exhaust steam.

If the failure causes the condensate source level control valves to the clean steam reboilers (2TME-E1A, E1B) to fail open, then condensate may rise in the reboilers and infiltrate into the turbine gland seal and exhaust steam system. This will'ause water induction into the low-pressure turbine, resulting in high turbine vibra-tions, which may lead ta turbine trip.

2) 2TME-PIC122 Failure Effect

3. Combined Effects

a. A break in breathing air high energy line in this zone has no impact on reactor parameters. Control component failure in this zone has no effect on reactor parameters.

Failure of control components in Zone D results in numerous effects (reference Section 3.b.). In this case, however, the high energy line failure is in an air system where pressure is less than '90 psig, and Zone D i;s a very large zone where the effects of releasing high temperature compressed air from Zone Z will not result in significant effects. In this case, therefore, 'the break is expected to have no .significant effect on the control components located in Zone D.

b. A break in hot water heating high energy line in this zone has no impact or reactor parameters. Control component failure in this zone has no effect on reactor parameters.

Failure of control components in Zone D is highly unlikely due to release of hot water from this break in Zone Z. In the event that failures do occur, however, the following summarizes the effects which might result:

1) Loss of feedwater, an event bounded by FSAR Sec-tion 15.2.7 analyses.

2) Feedwater controller failure - maximum demand, an event bounded by FSAR Section 15.1.2 analyses.

3) Partial loss of feedwater heating in fifth and sixth point heaters and second and third point heater drain coolers. and in only one of three fourth point heaters, an event bounded by FSAR Section 15.1.1 analyses.

4) Turbine trip, an event bounded by FSAR Section 15.2.3.

5) Loss of main condenser vacuum, bounded by FSAR Section 15.2.5 analyses.

For a detailed discussion of these events, refer to Appendix D, Zone D, Section 3.

c~ A break in instrument air high energy line in this zone has no.

impact on reactor parameters. Control component failure in this zone has no effect on reactor parameters.

Control component failures in Zone D due to failure of the in-strument air compressor discharge line in this zone are unlike-ly; a discussion of the failures which might occur, however, is provided in Section 3.b.
