RIVER BEND STATION - UNIT 1
1.0 INTRODUCTION
This report documents the results of a review of River Bend Station -
Unit 1 (RBS) plant electrical buses powering safety-related and non-safety-related instrumentation and control circuitry which, if lost, could affect the ability of the plant to attain a cold shutdown condition. This report also seeks to ensure that emergency procedures are adequate to address the loss of such buses.
This' review is in response to NRC IE Bulletin 79-27. It also 1
addresses a portion of R. L. Tedesco's (Assistant Director for Licensing, I
e Division of Licensing, Nuclear Regulatory Comrnission) letter dated April 16,~1981, and NRC Question 421.003 (Section 7.5 of RBS FSAR).
Additionally, a re-review of IE Circular 79-02, Failure of 120-V AC Power Supplies, to include both Class IE and non-Class IE power supply invert-ers, as required by IE Bulletin 79-27, has been completed. ,
s
- This report includes descriptions of the scope and approach and presents findings and recommendations for RBS.

'2.0 TASK DESCRIPTION 2.1 SCOPE a.
w The ' scope of this IE Bulletin 79-27 study includes the systems required to place the plant in a cold shutdown condition.
Independent of the event that initiates plant shutdown, the reactor is normally brought to approximately 100 psig using either the main con-denser or, in the . case of loss of offsite power or other conditions when the main condenser is not available, the reactor core isolation cooling system (RCIC) or high pressure core spray (HPCS) system together with the residual heat removal (RHR) system and the nuclear boiler pressure relief system. A protection sequence for shutdown was developed showing the different paths to achieve cold shutdown (Figure 3-1), and the systems directly or indirectly involved, in whole or in part, for each path.
The plant electrical system is divided into safety-related systems and nonsafety-related systems. The safety-related systems consist of three 4.16-kV ac systems, three 125-V de systems, and two 120-V. ac uninter-ruptible power supply systems. The safety-related systems are Class IE and are divided into three divisions, identified as Division I (red), ,
. Division II (blue), and Division III (orange).
The nonsafety-related .
systems consist of two 13.8-kV ac systems, five 125-V de systems, one 4S-V de system, six 120-V ac uninterruptible power supply systems, and ,
two reactor protection system (RPS) power supply buses. The nonsafety-C4/12210/127/4YH 2

>n related systems are non-Class IE, nondivisional, and identified as black.
Normal power for the plant electrical system comes from the station
. generator. ~ Preferred power for the statica is taken from two physically and electrically independent 230-kV line7 originating in the onsite 230-kV system. Each of the safety-related 4.16-kV ac sycteas has a
~
. standby 4.16-kV diesel generator capable of supporting it upon loss of
- normal and preferred . power. The 120-V ac uninterruptible power supply systems and 125-V de systems are supported by individual 125-V de station batteries. Each of the.two RPS buses normally is supplied from its own
! motor generator set.
l An electrical bus tree is constructed (Figure 3-2) to show the various ac l
l and de buses that could be used to achieve cold shutdown.
4 Table 3-1 lists ac and de buses and components that could ' be used . to achieve cold shutdown.
t Appendix A lists the referenced SWEC elementary diagrams and General Electric Company (GE) elementary drawings for the components itemized in Table 3-1.
Accordingly, this study contains a review of the power supplies for systems having direct or indirect impact on achieving cold shutdown
[= (Item 1 of IE Bulletin 79-27). Also included is a re-review of IE
- Circular 79-02 to include both Class 1E and non-Class IE safety-related power . supply inverters (Item 3 of IE Bulletin 79-27). A review of-the i

.o adequacy. of plant emergency procedures (Item 2 of IE Bulletin 79-27) is to be conducted by. Gulf States Utilities Company (GSU).
2.2 APPROACli The principal concern in this review was bus failures that' hinder the
. normal procedure for achieving cold shutdown. This review verified that proper information is available in the main control room to alert the plant operator of such a condition, so that he will be able to use an emergency - path. Two alternate emergency shutdown paths also are con-sidered to ensure the adequacy of plant shutdown capability.
The review of' the systems used for placing the plant in a cold shutdown condition (Item-1 of IE . Bulletin 79-27) was performed using the latest documentation of March 1,1984. Findings are based on issued flow dia-grams, elementary diagrams, and electrical one-line diagrams. Other documentation, such as logic diagrams, control system descriptions, con-
, trol loops, and analog wiring diagrams were used for background infor-i
mation.
Analyses for systems such as RHR, SLS, HPCS, RCIC, RMCS, CRD, NMS, RCS, i,
1 SW/ ADS, steam bypass, and nuclear boiler systems were performed by GE.

J.O.No. 12210 The review was performed using the following procedures:
- 1. Identify all. instrumentation and control. systems required to achieve a cold s}iutdown. Prepare ~'a flow chart showing shutdown l paths (Figure 3-1). ~
- 2. Identify instrumentation and control loads in each system required to achieve a cold shutdown.
- 3. Identify ac and de buses supplying power to the loads in Step 2 i1 above. Prepare a bus tree (Figure 3-2).
- 4. Evaluate effects of loss of power .to each bus on each asso-O L:
ciated device. Evaluate the cumulative effect of this loss of power condition on the ability to achieve a cold shutdown con-
'ditica by any of the paths shown in Figure 3-1.
- 5. Identify the alarm provided in the main control room to alert the plant operator of the loss of power to the bus. Verify that the annunciation of loss of power in the main control room is simple, clear, and unambiguous. .
, 6. Deternine if the loss of power to the bus would result in an unknown or undetected condition, or would compromise achieve- [
ment of cold shutdown.

SUMMARY
3.1 FINDINGS AND CONCLUSIONS The different paths that could be used to achieve cold shutdown are shown in Figure 3-1.
Table 3-1 summarizes plant design information gathered and the eval-uations performed as outlined in Section 2.2, and is formatted as follows:
- 1. Higher voltage level buses are addressed first. For each bus, the instrumentation and control loads and lower voltage level
. bases connected to them are tabulated. Annunciation available in the main control room on loss of power to the bus is noted.
The effect on the connected devices and the cumulative effect on cold shutdown upon loss of power to the bus are described. .'e The procedure to be followed by the main control room operator
[ .
upon loss of power to the bus is also described.

- 2. I.ower voltage level buses are addressed'in a manner similar to that described in Step 1 above.
- 3. The safety-related 4.16-kV ac ' buses, 125-V de buses, and 120-V ac uninterruptible power supply buses are addressed-separately to evaluate the effect of their backup sources.
The review shows that in the RBS design, all ac and dc buses (except the 125-V de bus discussed below) required to achieve a cold shutdown of the plant are- provided .with undervoltage sensing circuits. Clear, unambiguous annunciation is provided in the main control room to alert the plant operator of an undervoltage condition in any one of these buses.
This review also shows that there is no situation where a single bus power failure would prevent plant personnel from achieving a reactor cold shutdown. This conclusion is based primarily on the analysis results as shown in Table 3-1, which show that no single bus supplies power to all three shutdown paths. In most cases, single buses provide power to systems that are active in only one shutdown path.
3.1.1 Finding An undervoltage on the 125-V de bus 1BYS-PNLO1 is not annunciated in the ,
l main control room.

CWS pumps are started manually.
3.2 RE-REVIEW OF IE CIRCULAR 79-02 IE Circular 79-02 has been re-reviewed to include both Class IE and non-Class IE power supply inverters.
RBS has two 120-V ac safety-related uninterruptible power supply systems (IENB*INV01A and IENB*INV01B) and six 120-V ac normal. uninterruptible l
power supply systems -(IIHS-INV01, IBYS-INV01A, IBYS-INV01B, IBYS-INV02, 1BYS-INV04, and IBYS-INV06). The safety systems and the normal systems are identical in design except for IBYS-INV06.
The following discussion applies to all inverters except IBYS-INV06.
The problems described in IE Circular 79-02 are not present in the RBS UPS design. The RBS design employs considerable hysteresis in the low-voltage de sensing circuitry to prevent the shutdown of an inverter because of short-term de bus transients. With a sustained, ;
low de voltage condition, the inverter trips the de input breakers and transfers to the alternate supply circuit. Further, in order to prevent t.ransfers because of a high-voltage spike with a very fast a .C4/12210/127/4YH 8 w- - , , ;
' J.O.Ns. 12210-time riding on the alternate supply side, a regulating and bypass transformer-is used in series with the static hypass switch.
~'
The RBS design uses a high-voltage dc protection circuit to prevent the conditions described in Item (b) of IE Circular 79-02.
The review of IE Circular 79-02 for inverter IBYS-INV06 has not been completed by the vendor at this time.
