3.0 CONCLUSION

S APPENDICES AND ILLUSTRATIONS FIGURE 1 HANPORD COLD SHUTDOWN SYSTBS PATHS BUS SYSTEM CASCADE CHART APPENDIX A POWER BUS ANALYSIS TABLES 13-0174 1

1. 0 hNALYSIS OBJECTIVE The overall analysis objective was to determine vhether the loss of pover to any bus would jeopardize being able to briag the plant to cold shut-down.

This reviev vas conducted ia response to IE .Bulletia 79-27 which identi-fied specific actions to be taken in accomplishing the reviev. These actions are as detailed bclov:

1) Review the Class ]E and Non-Class 1E buses supplying power to safety and noa-safety related iastrumeatation aad contxol systems vhich could affect the ability to achieve a cold shutdown condition using existing plant operating. procedures or procedures developed for each bus in thc event of its failure.

2) Identify the instrument and coatrol system loads connected to the bus and evaluate the effects of loss of pover to these loads including the ability to achieve a cold shutdowa coadition.

3) Ideatify aad reviev the alarm aad/or indication provided ia the control room to alert the operator to the loss of power to thc bus.

4) Identify alternate indicatioa aad/or control circuits which may be powered from other Non-Class 1E or Class lE iastrumeatation and control buses.

5) Identify methods for restoring povex to thc buses.

6) Prepare emergency procedures or review existing oaes that will be used by coatrol room opexators, including procedures required to achieve a cold shutdown conditioa, upoa loss of pover to each Class 1E aad Noa-Class 1E bus supplying power to safety and non-safety related instrument aad control" systems.

13-0174 2

7) Describe any proposed design modifications or administrative controls to be implemented resulting from these procedures, and the proposed schedule for implementing the changes.

k comprehensive approach vas developed to analyze the consent@..nces of a bus failure during, cold shutdowa. Details of this approach are identified in the anlaysis methodology section. hlternate cold shutdowu paths, conclusions, and followup reconeendations are also discussed in their respective sections.

This report vith its appendices and illustrations vas prepared by the General Electric Company (GE) for Vashington Public Power Supply System (GPSS) . Significant technical contribution vas also provided by Burns and Roe, Inc. (BRI).

2.0 ANALYSIS METHODOLOGY The infoaaation required to analyze the effect of a bus failure on cold ahutdo<<n <<as obtained free both GK and BRI.

The division of responsibility for the inforaation and analysis gathering

<<as as folio<<a:

ASSIGNED TO 2.1 Identify Required Syateas 2.2 Identify Required Devices 2.3 Identify Required Buses 2.4 Determine Sc Seanarize Normal 8 Alternate Shutdo<<n 2.5 Determine IE and Non-1Z Loads 2.6 Analyze Bus Loss During Shutdovn 2.7 Analyze Cascade Effect of Combined Bus Losses 2.8 Determine Bus Loss Annunciation 2.9 Revier Plant procedures to Verify Appropriate Steps During Bus Loss 2.10 Mify/Augment Plant procedures if Necessary 13 0174 4

2.1 IDENTIFY RE UIRED SYSTEMS This step established the systems required for plant shutdown to a cold shutdown state. h list of QNP-2 plant systems and subsystems was compiled and grieved to determine only those systems necessary to achiere a cold shutdown. These systems were grouped together (see Figure 1) in their required normal and alternate shutdovn paths. h detailed discussion of the methods used to develop Figure 1 is discussed in Section 2.4 of this report+

2.2 IDENTIFY RE UHKD DEVICES Since not all devices in a system are required for shutdovn only those devices the operator would manipulate in going to cold shutdovn vere evaluated. System operating procedures (PPM's) vere reviewed in con)unc-tion vith the plant shutdown procedure (PPM 23.2.6) to properly evaluate devices required. The devices required for cold shutdown, the associated aanunciators, and pover busses vere analyzed system by system.

2.3 IDENTIFY HE UIRED BUSES The devices discussed in Section 2.2 vere reviewed to determine their pover supply bus(es). Al.l pover supply buses vhich have cold shutdovn devices vere then arranged to show how they are interconnected. Annun-ciators and loss of pover alarms for the buses were reviewed to det~rmine if the operator vould be alerted on loss of a bus. Figure 2 shovs all required buses, breakers and annunciators for these buses.

2.4 DETERMINE AND SUMMARIZE NORMAL AND ALTERNATE SHUTDO'4N PATHS The shutdown paths are as identified in Figure I. The information re-quired to determine the three basic shutdovn paths vas obtained from plant procedures, PAID's and RiP-2 CESAR system descriptions.

Pith reference to Figure 1, the alphabetical indicator, located in paren-thesis in each system block, (e.g., (E); (7); etc.) represents the cross 13-0174 5

reference code to the system device table Appeadix "A". Although each system descriptioa block, is located in its ova rcspectivc shutdown path, the Figurc does not necessarily show the sequential use of a particular system duxiag thc cold shutdova operation. For example; ia the normal cool dova path N, feedvatex (Group (J)) is showa as the fifth (5th) system in line. Contxol of feedvater occurs to some degree, priox and during condensate and condeasor vacuum (Group (F)) operations.

In addition, the use of normal RHR cooling occurs as a last eveat irre-spective of the shutdown path selection (aad use). Because of this, the MB Shutdovn Cooling Mode (L), is shown as the last event in the Normal Cooldown Path, and is essentially duplicated by coatrol of RHR "A" or RHR "B" in the alternate shutdown cooling modes.

2.5 DETERSIVE 1E AND NON>>IE LOADS A revicv of the plant single linc diagrams identified the 1E or Noa-1E class status. These desigaators have been iacludcd in the "Povex Bus Aaalysis Tables", Appendix "A", uader the heading of "Essentiality Code".

2.6 ANALYZE BUS LOSS DURING SEJTDORf This step consisted of determining the affect of a bus loss oa the ability to coatinue in the particular shutdown path that vas being used at the time the bus loss occurred. Infoxmatioa presented in Figures 1 aad 2 provided the facts necessary to analyze the consequences of a bus loss.

The conclusion effect, of coatinuiag in the existing shutdova mode is elaborated on ia the affects coluraa of the. Appendix A document.

2.7 ANALYZE CASCADE EFFECT OF COMBINED BUS LOSSES This step ia the analysis is a continuation of Paragraph 2.6, where the consequences of an upstream bus loss vill affect the cold shutdown path.

In all cases, transfer to alternate pover or transfer to other shutdova modes vere possible.

13"0174 6

2.8 DETERMINE BUS LOSS ANNUNCIATION It is necessary when a bus loss occurs that the control room operating personnel are alerted to the fact. This step in the analysis determined.

what type of warning was relayed to the control room, i.e., annunciation or undervoltage relay triggering "control voltage lamps."

The identity of the alarm, indicator, or annunciator are shown in the appropriate column iu Appendix A. major bus annunciators are also identi-fied on the "Bus system cascade chart" Figure 2.

2.9 REVIEW PLANT PROCEDURES TO VERIFf APPROPRIATE STEPS DURING BUS LOSS This step must be accomplished as a result of this analysis report. WPPSS or their designated engineers should provide this review. The primary response is to restore power to the affected power bus(es). If this, is not possible, then shifting to an alternate cooldown path is required.

2.10 BODILY/AUGMENT PLANT PROCEDURES

~

If plant procedures require modification after the Paragraph 2.9 review, then WPPSS should make the necessary changes. When the affects" column in Appendix A indicates that an alternate shutdown path is required, existing procedures or new supplemental procedures should be identified or prepared.

. 3.0 CONCMSIONS

. 3.1 AITERNATE SElTDORi PATHS Analysis of the zeport information shows no situation where a single Bus Pover Failure vould prevent plant personnel from achievtag a Reactor Cold Shutdown condition. This conclusion is based primarily on the analysis results as shovn in Appendix "h", vhich delineates that no single bus supplies povez to all three shutdown paths. In most cases, single buses pro&de power to systems that are active in only one shutdovn path.

3.2 BUS PADIEE ANNUNCIATION Bus failure of a major bus (i.e., 6.9 kV thru 480 Volt) is annunci-ated in the control room, thus giving the operator the knowledge that bus power is lost,. The review and analysis of Appendix "A" and Figure 2. shovs conclusively that contzol room personnel vill have bxowledge of individual bus or circuit failures.

1) THE LOSS OP BUS POWER XN THE hl PATH OP AFFECTING COLD SEJTDOWN REQUIRED THE CONSIDERATION OP TRANSFERRING TO THE SECOND ALTERNATE PATE A2 . THIS CONSIDERATION IS OBVIOUSLY DEPEJUJENT UPON THE TIME SEQUENCE OF BUS POWER LOSS (I E x XF THE hl SYSTEM HAS BEEN USED AND DROPPED'HEN TRANSFER TO THE A2 PATH IS NOT NECESSARY).

2) THE COMBINATION OP A SINGLE BUS POWER LOSS THAT AFFECTS DEVXCES IN TWO SHlJTDOWN PATHS (I.E. N AND hl . OR CN AKl C1 ) REQUIRES TRANSFERRING OP CONTROLS TO THE SECOND ALTERNATE SEJTDOWN PATH. (THIS IS NOT REQUIRED POR'AILURE OP Cl AS THIS ROUTE IS PAIL SAFE ON LOSS OF POWER.)

3) TRIS FEEDER BUS POWERS OTHER BUSSES THAT POWER DEVICES IN ALTERNATE SHIJTDOWN PATHS. TRANSFER OP THE SHUTDOWN MODE TO THE MEZT ALTERNATE PATH MUST BE ACCOMPLISHED IF BUS POWER CANNOT BE RE-ESTABLISHED.

4) LOSS OP h COMMON POWER BUS THAT AFFECTS A CORE SHUTDOWN PATH AND HEAT REMOVAL PATH REQUIRES h TRANSFER TO THE FIRST AVAILABLEALTERJATE. SZNCE BOTH PATES ARE NOT REQUIRED SIMULTANEOUSLY, FtlRTJKR ANALYSIS NOT NECES SARY.

5) THIS FEEDER BUS POWER OTHER BUSSES THAT POWER DEVICES IN THE SAME COLD SHUTDOWN PATHS. TRANSFER TO THE FIRST ALTERNATE SHUTDOWN PATH ZS NECES-SARY.
