r 1.0 . ANALYSIS OBJECTIVE ,

1 The loss of a Class IE or a non-Class IE power bus may result in the loss of instrumentation providing information on plant parameters to the oper-ator. A concern has been raised as to whether the operator would have enough information available to take proper actions if the loss of a bus were to occur concurrently with a plant event requiring the operator to bring the plant to a cold shutdown ecndition. In response to IE Bulle-tin 79-27 and Hope Creek Generating Station (HCGS) Final Safety Analysis Report (FSAR) Question 421.42, an analysis was conducted to determine whether loss of power to identified busses would impede the ability of the operator to bring the plant to a cold shutdown condition.

The actions performed in conducting the analysis are detailed below:

1) Review HCGS Emergency Operating Procedures to identify Class IE and non-Class IE power buses supplying power to safety- and nonsafety-related instrumentation that could affect the ability to achieve a cold shutdown condition.

2) Identify the instrument loads connected to the bus and evaluate the effects of loss of power to these loads in achieving a cold shutdown condition.

1

3) Identify and review the alarms and/or indications provided in the control room to alert the operator of the loss of power to the bus.

4) Identify alternate indications and/or instruments that may be powered from other non-Class 1E or Class IE buses.

5) Identify methods for restoring power to the buses.

6) Describe any proposed design modifications or administrative controls to be implemented resulting from this analysis and the proposed schedule for implementing the changes.

A comprehensive approach was developed to analyze the consequences of a bus failure during cold shutdown procedures. Details of this approach are 11-1176 (3) 1

identified in the analysis methodology sectien. Fellcw-up r:commendaticas are discussed in Sections 2.6 and 2.7, and conclusions are discussed in Section 3.0.

2.0 ANALYSIS METHODOLOGY The methodology required to analyze the effect of a bus failure on the ability to achieve a cold shutdown condition was conducted as follows:

ACTIVITY 2.1 Identify Required Systems 2.2 Identify Required Devices 2.3 Identify Required Buses 2.4 Analyze Bus Loss During Shutdown 2.5 Determine Bus Loss Annunciation 2.6 Review Plant Procedures to Verify Appropriate Steps 2.7 Modify / Augment Plant Procedures if Necessary 2.1 IDENTIFY REQUIRED SYSTEMS This step identified the systems required to bring the plant to a cold shutdown under emergency conditions. HCGS systems and subsystems were compiled and reviewed to determine only those systems necessary to achieve a cold shutdown condition.

2.2 IDENTIFY REQUIRED DEVICES Only those devices that provide information to the operator to achieve a cold shutdown condition were identified. The HCGS Emergency Operating Procedures (see Table 3 of Appendix A), system drawings, and Table 7.5-1 of the HCGS FSAR were reviewed for the identification of the devices required. These devices are tabulated in the "Affected Device" column in Table 1 of Appendix A.

11-1176 (4) ,

l

b 2.3 IDENTIFY REQUIRED BUSES The . devices discussed in Section 2.2 were reviewed to determine their power supply bus (es). The . associations between .the devices and their

. power buses are shown in Table 1 of Appendix A. This table is arranged by power supply buses that support the required devices determined to . be necessary for cold shutdown.

2.4 ANALYZE BUS LOSS DURING SHUTDOWN This step consisted of reviewing system drawings, HCGS FSAR, and HCGS Emergency Operating Procedures to determine the effect of a bus power loss I

and the ability to continue and achieve safe shutdown of the plant.

Redundant systems or alternate information devices that are supplied by a

different power bus than the associated affected device and that provide the required parameter information to the operator were identified.

Information presented in Table 1 and 3 of Appendix A provides the facts l necessary to analyze the consequences of a bus loss. Each instrument bus I

of a power bus was analyzed from the lowest level to the highest level to ensure the failure of the power to a channel, et any level, would not affect the power supplies of the redundant systems or alternate information devices for the affected devices.

i

! 2.5 DETERMINE BUS LOSS INDICATION OR INFORMATION t

System drawings were reviewed to identify what type of information (i.e. ,

annunciators, recorders, or computer points) would be relayed to the operator to alert him of a bus loss. This information is identified in Tables 1 and 2 of Appendix A. It should be noted that the HCGS design

conforms with the requirement of the May 1973 revision of Regulatory Guide 1.47 for adequate annunciation in the control room for indicating j inoperable safety-related features for the protection system and the

. engineered safety systems (see the response to NRC Question 421.7).

I Additional safety-related bus loss indicators and system out-of-service indicators are displayed in the control room to provide additional infor-mation to the operator (see Section 7.5 of the HCGS FSAR).

2.6 REVIEW PLANT PROCEDURES TO VERIFY APPROPRIATE STEPS Existing HCCS Emergency Operating Procedures, (tabulated in Table 3 of Appendix A), were used throughout the analysis methodology. A review will be made of the results of this report against the final Emergency Operating Procedures. The review will also verify that procedures to restore power to the affected power bus (es) are adequate.

2.7 MODIFY / AUGMENT PLANT PROCEDURES If modification of the plant procedures is indicated by the review de-scribed in Paragraph 2.6, the necessary changes will be made. If the data in the effects column in Table 1 of Appendix A indicates that an alterna-tive shutdown path may be required, then the final plant operating proce-dures will be reviewed and modified as necessary.

3.0 CONCLUSION

S 3.1 ALTERNATIVE SHUTDOWN PATHS Analysis of the report information shows no situation where a single bus power failure would prevent plant personnel from achieving a safe shutdown condition. This conclusion is based primarily on the analysis results shown in Appendix A. The results establish that no single bus supplies power to all existing shutdown paths. The assignment of the instrument loads identified in this analysis is such that the loss of one bus would not prevent the minimum safety function from being performed.

3.2 BUS FAILURF ANNUNCIATION The failure of the buses identified in Table 2 of Appendix A are annun-ciated and are displayed by the computer in the control room, thereby giving the operator the knowledge of which power bus is lost. The review and analysis presented in Tables 1 and 2 of Appendix A, shows conclusively that control room personnel will have knowledge of individual bus and/or circuit failures, and that the operator has alternate instruments and shutdown paths available to achieve a cold shutdown condition.

3.3 MODIFICATIONS As a result of this analysis, no changes to present plant design and procedures are indicated.

1. THE

• PROCEDURE NUMBER

• COLUMN IDENTIFIES THE PROCEDL1tE NUMBERS OF THE HCGS EMERGENCY OPERATIONS PROCEDURES THAT REQUIRE THE AFFECTED DEVICE FOR ACHIEVIN COLD SHUTDOW CONDITION. THESE PROCEDURES ARE TABUIATED IN TABLE 3 0F APPENDIX A. ALL PROCEDURE NUMBERS ARE PRECEDED BY "0P-E0 ZZ".

2. THIS COLUMN PROVIDES A TABULATION OF ADDITIONAL INDICATIONS, I.E., ANNUNCIATOR TRIP OR LOSS OF A COMPtTTER POINT, WICH MAY BE IDST ALONG WITH THE LOSS OF THE AFFECTED DEVICE.

3. ELECTRICAL DIVISIONAL SEPARATION SCHEME USED BY NSSS IS DESIChATED AS DIVISION D1 ESF, D2 ESF, D3 EST, AND D4 ESF FOR IE BUS, AND N FOR NON-1E BUS.

THE NON-NSSS DESIGNATION USES CHANNT.LS A, B, C, AND D FOR 1E BUS WITH N DESIGNATION FOR NON-IE BUS. FOR RPS POWER SUPPLY, NSSS USES DI RPS, D2 RPS, D3 RPS, AND D4 RPS WICH CORRESPONDS TO THE NON-NSSS CHANNELS W, X, Y, AND Z. FOR THE NEITTRON MONITORING SYSTEM SEPARATION NSSS USES NA, NB, NC, AND ND, AND NON-NSSS USES CHANNELS R, S, T AND U.

4. OTHER ALTERNATE STSTEMS AND/OR ALTERNATE INFORMATION INSTRUMENTS MAY BE AVAILABLE IN ADDITION TO THOSE LISTED IN THIS COLUMN.
