1.0 INTRODUCTION
1.1 PURPOSE The purpose of this study was to verify that the effects of any high energy line break (HELB) on any nonsafety-related control I systems in River Bend Station (RBS) do not result in an event more severe than the events analyzed in Chapter 15 of the RBS Final Safety Analysis Report (FSAR). 1.2 SCOPE OF STUDY The scope of this HELB analysis was restricted to HELBs and their I 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-I sented in Section 2.1 and the component elimination criteria identified in Section 2.2 of this report. IELB zones containing both control systems components of interest and HELB locations were defined using the appropriate Environmental Design Criteria I (EDC) 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 Sec-tion 3.0. 1.3
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. I The detailed analysis (Appendix D) describes each of postulated HELB events and their limiting effects on the reactor the parameters. The detailed analysis in Appendix D is summarized I in Section 3.0. With the exception of the loss of feedwater heating exacerbated by a turbine trip, the effects of the postulated HELB/ control systems failures events are less severe I than the Unacceptable Results for Incidents of Moderate Fre-quency - Anticipated Operational Transients presented in FSAR Chapter 15. It is concluded that safe reactor shutdown is ensured for all events postulated herein, and the consequences of I 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:
- 1. Identify all nonsafety control systems and components which (e.g.,
I could impact the critical reactor parameters level, pressure, critical power ratio). water
- 2. Identify high energy lines and their postulated break loca-
- tions and evaluate consequences.
C4/12210/457A/4YH 1
I
- 3. Identify the plant zones which contain both HELB locations and control systems components determined in Item 1 above.
I 4. Postulate pipe breaks in each of the zones defined, deter-mine which control systems components are affected, and analyze the consequences of failure of the control systems components.
- 5. Combine the effects of the HELB with potential, simultaneous malfunctions of control systems components in the postulated I HELB zone and determine the effects on the critical reactor parameters.
I 6. Verify that the effects on critical reactor parameters enveloped by the analyses in Chapter 15 of the FSAR. are I 7. Identify any postulated events that are beyond Chapter 15 analyses and recommend corrective actions. 2.1 SYSTEM ELIMINATION I All nonsafety-related control grade systems which may affect the critical reactor parameters have been included in the HELB anal-I ysis, and the following elimination criteria were applied to ex-clude some of the systems. Some safety-related systems with a postulated HELB of QA Category I piping leading to failure of I nonsafety grade control components, such as the residual heat removal system, have also been included in the analysis. The elimination criteria and bases identified for RBS are as follows: Elimi-nation Criteria Basis NI 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 I 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 bat have no direct or in-I direct effect on reactor parameters, such as venti-lation systems. I N4 Control systems that do not interact or interface with reactor operation or reactor pirameters either directly or indirectly, such as communications, lighting, etc. C4/12210/457A/4YH 2
I N5 Systems which are used during shutdown or refueling mode. I 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, without high energy lines or with high energy lines away from control I components. 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 plint components. The following elimination criteria are applied to the remaining components to arrive at the final list of components considered I in the detailed HELB analysis. The appropriate system piping and instrumentation diagrams and elementary diagrams have been used to aid in this elimination.
- 1. Mechanical components (e.g. , structural steel, tanks, pipes, valves) are not considerei control systems components sub-However, instrument taps and tubing for I
ject to failure. components of interest, which may be physically located on mechanical components, are included. I 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 I in the detailed HELB analysis, along with their related taps and process tubing. Motor control centers (MCC) in the a f fected zones were considered as components subject to failure and were reviewed for MCC-mounted control components or power supply to I components of interest. No nonsafety grade control system com-ponent in this analysis is mounted in or powered directly from an MCC, and MCCs were, therefore, eliminated. C4/12210/457A/4YH 3
I . 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 I The criteria for determining high energy lines used in the study were based on criteria established in Section 3.6 of the RBS FSAR. High energy piping is defined as those fluid systems that during normal plant conditions, either are in operation or are I maintained pressurized under conditions where either or both of the following are met:
- 1. Maximum operating temperature exceeds 200*F
- 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, I therefore, are excluded from the scope of this study.
whose diameter is 1-in. NPS or smaller is also excluded. Piping I 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 EDC zone map was used for identifying normal operating environmental zones. I These EDC zones were subdivided into HELB zones which are open areas bounded by walls, ceiling, floors, etc. Each HELB zone is uniquely identified. Certain HELB zones extend between eleva-I tions because some floor elevations consist of open grating or a hoist opening is common to all the floors. I Though the turbine enclosure is divided into discrete zones with unique identification, it was determined during plant walkdown that the doors are not sufficiently pressure tight. A HELB event I in a small cubicle can conceivably blow out the door and the 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 I 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:
- 1. Zones XV and VIII combined for a break in Zone XV
- 2. Zones XVI and VIII combined for a break in Zone XVI I 3.
4. Zones XI and I combined for a break in Zone XI Zones XII and I combined for a break in Zone XII
- 5. Zones V and VIII combined for a break in Zone V C4/12210/457A/4YH 4
I
- 6. Zones VI and VIII combined for a break in Zone VI
- 7. Zones XX and VIII combined for a break in Zone XX
- 8. Zones 13 and 15 combined for a break in Zone 13 Zone 16 with low temperature, high pressure condensate (CND) and condensate demineralizer (CNM) system piping only will not I similarly impact the adjoining Zone VIII and has, therefore, been excluded from the foregoing consideration. For the same reasons CND, CNM, and CNA (auxiliary condensate) system HELB events have been excluded from the zone interaction listed above.
The sacrificial approach used througout the analysis assumed that any HELB within a defined zone would impact all control system I components in the zone. Because of the large area covered by Zones III and VIII, the potential impact of a line break was further analyzed to verify if a break at one end of the turbine I building can realistically fail nonsafety grade components located at the other end with intervening barriers, such as pipes. walls, turbine casing, etc. It was determined that in the condenser and heater bay areas, a pipe break may affect the I componeats in only a confined portion of an " architecturally" defined zone. While the distance between the postulated break on high energy line and control components precludes the possibility I of physical damage to components due to pipe whip and jet impingement, the bays allow for the adverse environment associated with the break to spread throughout the condenser or I heater bay, which is a large open zone, minimizing the environ-mental effects. Therefore, even though no air / steam / water boundary exists in the I condenser and heater bay areas, the above consideration has been used in the analysis of Zones III and VIII and the sacrificial approach applied within the confines of the zone determined above. For the reactor enclosure, a list of the nonsafety components I which affect the reactor parameters was made. The locations of the components were then checked to determine whether these components are affected by any HELB event in their vicinity, and the consequence of their failure was analyzed. The only high l I energy line which is found to affect any nonsafety grade control component belongs to the control rod drive system at the 114 f t l 0 in. level, and based on the zone criteria outlined above, the reactor enclosure was divided into two zones, C1 and C2. Reactor core isolation cooling (ICS) (steam side), reactor water cleanup (WCS), and residual heat removal (RHS) (steam condensing mode) system piping are the only sources of HELB events in the auxiliary building and are capable of producing temperature transients to fail all nonsafety grade instruments in the zones I identified in the EDC report. A review of the relevant drawings identified six zones to be considered for analysis. I

I All areas of the radwaste, diesel generator enclosures, and con-trol building were eliminated from analysis due to the absence of high energy lines in these areas. The main steam tunnel has also been excluded because it contains no nonsafety grade instruments. The auxiliary boiler enclosure has been eliminated because it contains auxiliary steam system components, and a HELB failure can lead to a single system failure only. The fuel handling building has some control components at eleva-tion 70 ft 0 in. in the vicinity of high energy piping associated with the control rod drive (CRD) system and are therefore subject to failure due to a HELB event in the CRD system. However, the control components also belong to the CRD system, and a HELB I event will result in a single system failure. The fuel handling building has therefore been eliminated. 2.5 PIPE BREAK LOCATION AND EFFECTS 2.5.1 Pipe Break Location The high energy pipes identified in Appendix C are assumed to break at all locations where control systems components of interest (as defined in Section 2.2) are physically located in I the same zone as the high energy piping, unless piping runs sub-ject to high stress have been specifically identified and ana-lyzed as a result of the studies in FSAR Section 3.6. Piping I evaluated by means of previous HELB studies (see FSAR Sec-tion 3.6) is considered 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 Appendix D, the worst case combination of a specific HELB and consequential control systems failures is examined for the reactor in the limiting condition for that po-tulated event. 2.5.2 Pipe Break Effects I Pipe breaks and consequential control systems failures are eval-uated considering the effects of pipe whip, jet impingement, and adverse environment on the control systems components. The ef-fects associated with any adverse environment (increasing humid-ity, temperature, pressure, radiation) are enveloped by employing the sacrificial approach. The sacrificial approach assumes that any HELB within the defined zone would adversely impact all con-I trol systems components in the zone. Using this approach, en-vironmental effects are enveloped in the detailed analysis pre-sented in Appendix D. The turbine generator electrohydraulic system (TMB) is a high pressure, low temperature system with a limited volume of EH liquid maintained in high pressure by a small capacity pump. It is inconceivable that a pipe break in this system will incapa-citate 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 I C4/12210/657A/4YH 6
I direct pipe whip will be considered as the only causes of failure for those nonsafety grade instruments that are within such bounds. I 2.5.3 Pipe Whip Considerations l Movement of a circumferential1y broken pipe is assumed to occur I l in the direction of the jet reaction waile the pipe hinges at the i nearest rigid support, anchor, or penetration, producing an arc I The pipe is allowed to move in an are with a radius of motion. from the break to the hinge point, and motion is assumed to be limited by pipes of equal or greater diameter or reinforced con-crete walls, floors ,' or columns. The whipping pipe is assumed I capable of incapacitating any control systems components within the arc of motion. The sacrificial approach envelops these pipe whip considerations. l l 2.5.4 Jet Impingement Considerations Jet impingement is considered for both circumferential and longi-I tudinal breaks. The basic approach assumed is that the jet from a postulated break is sufficient to fail all impacted components l within the jet cone of influence, except in those areas where I major structures provide natural barriers. The sacrificial ap-proach used in this analysis envelops these jet impingement con-siderations. 2.6 PLANT WALKDOWN Preliminary zone maps for the reactor, turbine enclosures, and I auxiliary building were used for the walkdown. The plant walk-down was performed to accurately define appropriate zones, giving due consideration to wall heights, location of doors, wall openings, etc.
- The present study is based on the assumption that the location of )
,g the control components and their associated taps, tubing, and the 1E high energy lines are correctly represented in the referenced j drawings. Field or subsequent design changes may affect loca-tions of a small percentage of these components, and a second I plant walkdown will be conducted to verify the assumption. This l walkdown will also be used to establish those instruments which I I are affected by a HELB in the turbine generator EH fluid system ! referred to in Section 2.5.2. Any significant changes as a ' l l result of the walkdown will be incorporated in a later revision l of the study. 2.7 HELB ZONE ANALYSIS The detailed analysis was performed on a zone basis. The follow- i , ing description is representative of the analysis perfor:ned for l l each HELB zone.

determine the effects of a piping failure upon its own system. This is done for each high energy line or group of I lines having the same function independently, since only a single pipe break is postulated as the initiating event. The effect of the break itself on reactor parameters was examined and compared with the bounding FSAR Chapter 15, I where appropriate. 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 systems 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 on all controlled compo-nents were reviewed. Controlled components are assumed to j I operate in the worst possible mode as a result of single or group of components' failure, and this mode has been identi-fied in the analysis. Uhere 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-I ures of control systems components in the zone to determine whether any combination of possible failures could exacerbate the postulated HELB. The sacrificial approach l
3 was used, and the worst case combined HELB and possible E consequential control systems failures were defined and analyzed. The consequences of these events were compared to the accident and transient analyses presented in FSAR Chapter 15, which include discussions of a single additional active component failure to ensure that they are less severe than the existing analyses. I
3.0 CONCLUSION
S AND RECOMMENDATIONS l g The detailed analysis of Appendix D presents a thorough dis-l 3 cussion of the analysis performed for those zones of the Turbine Enclosure, Reactor Enclosure, and Auxiliary Building which required evaluation under the criteria set in Section 2.0. The I 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 C4/12210/457A/4YH 8
event beyond those already assumed in the existing FSAR Chapter 15 analyses. The worst case combined effects of the postulated HELB and consequential 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 I exacerbated by any combination of control systems failures in the zones. In some cases, control system component failures had insignificant effect on the controlled system and no further I analysis was made. The applicable bounding FSAR Chapter 15 event has been alluded to 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 and conclude that the combined consequence of failure is less severe than the existing analysis (i.e., bounded events). The following conditions as a result of pipe break are listed below. These conditions can occur individually or in combination as described under Combined Effects in Appendix D.
- 1. 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.
- 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. Combination of hypothesized conditions.
g Each of these conditions is analyzed below to determine the E overall consequences on reactor parameters. A loss of main condenser vacuum could possibly result either I 1. from a break in a high energy line leading to the condenser or steam jet air ejector or from a break in one of the turbine sealing steam supr'; lines, allowing air leakage at the low-pressure turbir e aft seals. A loss of sealing steam would produce , u.h more gradual loss of condenser vacuum than would a ,t- in a line from the condenser. l l l C4/12210/457A/4YH 9 l
l I l Both conditions would lead to a turbine trip situation, I which is bounded by Chapter 15.2.5 of the FSAR. I 2. A turbine trip due to high vibration as a result of water induction could also lead to a "turoine trip with bypass" situation, since the bypass would not be affected and would j operate as required.
- 3. A turbine trip could occur as a result of a high level i signal 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 turbine 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 I main condensate or feedwater lines is assumed to rupture.
The feedwater pumps would no longer be able to feed the reactor vessel, which would quickly lead to a reactor scram I on low water level. This loss of feedwater accident (LOCA event) is bounded by Chapter 15.2.7 of the FSAR. 6. I A loss of one reactor feedwater pump would result in no adverse consequences on reactor parameters. remaining RFP would automatically operate to supply The 70 percent of the normal feedwater flow to the reactor. The reactor recirculation pumps and the main turbine would receive a signal to run back at this time. Steam flow and power output would be reduced to the 70 percent level.
- 7. A partial loss of feedwater heating could occur when:
- a. Steam extraction lines to heater are broken.
I b. Drain lines are ruptured.
- c. Heater controls are adversely affected.
- d. Feedwater/ condensate is bypassed around heater.
l e. A heater string of one train is isolated. The largest possible reduction in feedwater temperature postulated assumes that the first through sixth feedwater heaters of one train and the first point heater of the other train are out of service, resulting in loss of feedwater heating energy. The reduction in feedwater temperature up l C4/12210/457A/4YH 10 i
I to 100 F would cause a gradual increase in reactor power level, which failing operator action, could eventually lead to a reactor trip.
- 8. Loss of reactor core isolation cooling pump can result due to a break in the RCIC steam piping, but the break is I automatically isolated by resultant high ambient temperature sensors, which are not postulated to fail (QA Category I).
9. I Tripping a single reactor recirculation pump due to a failure of instrumentation requires no safeguard or pro-tection system operation as analyzed in FSAR Chapter 15.3.
- 10. 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 I heating (condition 7) and a turbine trip (condition 1 or 2) if the appropriate controls improper valve positioning.
are disabled, leading to The reduction in feedwater inlet temperature causes a gradual rise in reactor power, and depending upon the specific timing of the event, the turbine trip may occur at I a reactor power elevated between the operating value and the trip level. It has been concluded that the occurrence of this event is highly unlikely. This conclusion is based in I 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 important line.
- b. Pipe whip of jet impingement can strike all targets in an area and cause failures in worst case modes.
- c. Breaks occur at worst case locations.
e
- d. Both turbine trip and reactor high power-level trip occur at appropriate (i.e. , worst cases) 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 Incidents of Moderate Frequency - Anticipated Operational Transients. This transient condition will be analyzed and the results included in a later revision of this report. All other combinations of the first nine conditions result l in effects which are bounded by previously reported transient conditions as analyzed in FSAR Chapter 15 and noted in Appendix D. It is concluded that the hypothesized IELB , with resulting effects on control systems, poses no significant risk to the health and safety of the public. C4/12210/457A/4YH 11

l \ APPENDIX D DETAILED ANALYSIS
APPENDIX D The format followed throughout this appendix is described in Section 2.7. Turbine Enclosure The turbine enclosure was divided into 20 zones: I, III, V, VI, VII, VIII, XI, XII, XIII, XV, XVI, XIX, XX, 9, 10, 11, 12, 13, 15, and 16, following the zone determination criteria described in Section 2.4. These zones are represented in Figures 1, 2, and 3 (attached). Zones VII, 9 through 12, and 16 are eliminated from the detailed analysis for at least one of the following two reasons:
- 1. No high energy lines are routed through these zones.
l
- 2. No applicable control systems components reside within these zones.
Reactor Enclosure The HELB analysis was limited to el 114 ft 0 in. of the containment area of the reactor enclosure. Drywell and other areas / elevations of the reactor enclosure do not have any nonsafety grade control systems components and have therefore been eliminated. Auxiliary Building The EDC zone map identifies various zones affected by temperature tran-sients severe enough to fail nonsafety grade instruments due to accidents including HELB, but only six areas marked in HELB zone maps have been con-sidered for analysis as explained in Section 2.4.

- 3. Combined Effects
- a. A break in the condensate demineralizer high energy line in this zone will result in loss of main condenser vacuum bounded by FSAR Chapter 15.2.5 analyses. The failure of any control components in this zone does not exacerbate this event.
- b. A break in any of the condensate energy lines in this zone (Items 1.b-1 through 1.b-4) will result in total loss of feedwater to reactor. Feedwater pumps will trip on low suction pressure. A break in any of the condensate high energy lines in this zone (Items 1.b.5 and 1.b.6) will result in gradual reduction in feedwater flow, reduced condensate inventory, and generator load reduction. Reactor feedwater pumps will trip ultimately on low suction pressure. The above events are breaks in feedwater line outside containment and are bounded by FSAR Chapter 15.6.6 analyses. The failure of any control components on this zone does not exacerbate these events.

- a. A break in any of the condensate high energy lines [ Item 1.a.1) or 1.a.2)] will result in total loss of condensate flow in feedwater heater train associated with the pipe break. A low feedwater suction pressure will result in reactor feedwater pump trip. This is a break in feedwater line outside the containment and therefore is bounded by FSAR 15.6.6 analyses.
Failure of control components in this zone does not exacerbate this event.

Moisture separator drain receiver tank associated pipe break results in loss of condensate inventory, reduced heater drain pump flow, and loss of condensate /feedwater heating at associated third point heater.

If the high energy line break in this zone results in failure of moisture separator drain tank receiver salve 1DSM-LV75A or IDSM-LV75B in closed position, condensate discharge to third point heater is reduced as well as third point heating. Instrumentation on drain tank will open valve 1DSM-LV78A, bypassing condensate to condenser. However, if IDSM-LV78 also fails to open on tank high level, moisture separator tank level will backup in moisture separator reheater and turbine trip will result.

- 1) IB33*PTN040 Failure Effect If this reactor vessel dome pressure instrument fails in either maximum or minimum output directions, it will effect the thermal shock interlocks for reactor recirculation pumps IA and IB start circuit logic.
- 2) IB33*FTN011A and *FTN011B Failure Effect Failure of these reactor recirculation flow instruments can cause the reactor recirculation valves to fail either closed or open.
- c. Control Rod Drive Hydraulic System (RDS, 36-1)
IC11-FTN004, HSSD009A, HSSD009B, I/PK001, and FCR60u Failure Effect If this reactor control rod drive flow control instrumentation fails, worst case failure would be the total loss of control rod drive system cooling and loss of hydraulic control unit supply to accumulators.
- d. Feedwater Control System (C33)
- 1) IC33*FTN003B and FTN003D Failure Effect If this reactor steam flow control instrumentation fails, feedwater flow control valves may receive false signals from the three-element feedwater control system for two of the four steam flow input signals. The other two steam flow control input transmitters are located in zone C2.
This failure can directly cause an increase in coolant inventory by increasing the feedwater flow. With excess feedwater flow, the water level rises to the high level reference point at which time the feedwater pumps and the main turbine are tripped and a scram is initiated.

(
- 2) IC33*PTN008B 1 Failure Effect If the steam dome pressure instrument for the reactor fails to either maximum or minimum output of the pressure transmitter, the recirculation pump cavita-tion interlock will be affected. Since this pressure signal is indica-tive of temperature differential between the steam dome and recirculation pump suction, an indication of a high differential will trip one recircu-lation pump and cause the reactor core flow and power level to stabilize at a new equilibrium condition.

- 1. The following is a list of high energy lines analyzed on a system basis:
- a. Reactor Core Isolation Cooling (ICS, 27-6)
All lines in auxiliary building Function The high energy line is limited to the piping which provides decay heat steam from the reactor vessel to the reactor core isolation cooling pump turbine. Failure Effect A pipe break in any section of the auxiliary building will cause loss of reactor coolant and temperature transient in some areas in the auxiliary building identified in the EDC report.
,/ However, the steam supply to the turbine is automatically
' isolated on detection of a pipe break, and the loss of reactor coolant is minimized.
- b. Reactor Water Cleanup (WCS, 26-3)
All lines in auxiliary building f C4/12210/459L/4YH D-AB-1
Function The high energy piping in the auxiliary building is limited to those associated with reactor water cleanup pumps PC-001A and ( 001B suction and discharge. These lines circulate reactor coolant through the cleanup system and return the clean liquid back to the reactor. Failure Effect A break in either the suction or discharge side of the pump will cause loss of reactor coolant. However, consequent temperature rise in the vicinity of the break will isolate the suction and discharge isolation valves minimizing the loss. In addition, a break on the suction side of the pump will trigger the low flow sensor to shut down the pumps,
- c. Residual Heat Removal System (RHS, 27-7) Steam Supply Lines Function The high energy lines are limited to the piping which diverts steam to RHR heat exchanger during RHR steam condensive mode.
Failure Effect A break in either the suction or discharge side of the pump will cause loss of reactor coolant. However, consequent temperature rise in the vicinity of the break will isolate the suction and discharge isolation valves minimizing the loss. In addition, a break on the suction side of the pump will trigger the low flow sensor to shut down the pumps.
- 2. The following is a 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 consequences of failure of each control component is analyzed. Refer to Appendix B for the function of individual com-ponents.
- a. Reactor Plant Component Coolina Water (CCP, 9-1)
- 1) ICCP-I/P-128 1CCP-TVX-128 1CCP-TVY-128 Failure Effect Failure of a single or the group of instruments listed above may cause bypass valve ICCP-TVX-128 to open and control valve ICCP-TVY-128 to close. This will allow the component cooling water to bypass the heat exchangers, thereby raising the CCP water temperature and may have a long-term effect on the life of the reactor plant com-ponents.
C4/12210/459L/4YH D-AB-2 m .
2). ICCP-PT127 Failure Effect Failure of this instrument will not allow the automatic startup of the selected standby component cooling water pump. However, onc pump is always running and a complete loss of component cooling will not occur.
- 3) ICCP-LT120 The surge tank may go solid but will not significantly affect the operation of the system. Makeup water system itself is eleminated by using system elimination criteria.
- 3. Combined Effect
- a. A break in the ICS or RHS steam piping will cause some loss of reactor coolant and temperature transient in the auxiliary building but there will be no effect in normal reactor opera-tion. Failure of control components will not exacerbate the condition,
- b. A bre:k in WCS system piping will degrade the reactor water quality. However, there will be minimal impact on the reactor coolant inventory because the system is used mainly in a recir-culatory mode. Concurrent failure of control components will have no worse effect on the system.
