ATTACHMENP 1 CLINTON POWER STATION UNIT 1 ILLINOIS POWER COMPANY Part A This Section contains those items which were deemed necessary to

.tna corrected prior to issuance of an operating license. Following each item is a statement of Illinois Power Company (IP) corrective action.

A-1. CONTROL ROOM WORKSPACE

1. Access to the Remote Shutdown Panel is not currently limited.

(A.l.2)*

Corrective Action The Remote Shutdown Panel is located in a vital security area to which access will be limited to approved personnel through the use of key cards and security doors.

2. There are no provisions for storage of procedures at the Remote Shutdown Panel. (C.l.4)

Corrective Action Present plans are to provide adequate storage space for necessary procedures which would be accessible to the operators. This is to be done after the panel is released to Plant Staff.

i

• Throughout the report the use of parentheses, such as (C.l.2), refer l to the part, section, and finding number used in the HFEB Control

}

Room Design Review / Audit report, dated December 3, 1981.

?

I e l 1

l A' 3 .

ANNUNCIATORS j

1. The audible signals to indicate cleared alarms on the annunciator system do not have a finite duration of activation.

Manual operator action is required to silence the cleared alarm signal. (C.3.4) l Corrective Action CPS believes it is imperative that the operator promptly reset all cleared annunciators. This is necessary to eliminate a potential source of confusion during transients. For this reason,.the CPS Control Room has been designed so that positive action is required by the operator to silence the " cleared" audible signal.

The loudness of the cleared tone will be adjusted.

2. The vertical columns and horizontal rows of the annunciator panels have_not been labeled with easily visible alphanumerics to facilitate visual location of each tile in a panel by its matrix coordinate designation. (C.3.5)

Corrective Action Vertical columns and horizontal rows of the annunciator panels now have alphanumeric labeling.

3. Annunciator acknowledge, silence, test, and reset buttons are large, grey, and flat surfaced on some panels: and large, silver, and recessed on other panels. (A.3.10)

Corrective Action The annunciator pushbutton's shape (large, square) distinguishes these controls from all other controls. Grey demarcation and label plates have been used to further distinguish annunciator pushbuttons.

4. The annunciator ACKNOWLEDGE pushbutton in the P803 annunciator control pushbutton group is not labeled to identify its function. (C.3.13)

Corrective Action The annunciator ACKNOWLEDGE pushbutton has been labeled to identify its function.

r A-3. ANNUNCIATORS (Continued)

5. The annunciator panel'on P801 for the B system is missing the

" Trouble.VD System Local IPL55J". (A.3.ll)

Corrective Action Engineering evaluation of this concern has revealed that only one annunciator alarm is necessary. The local panel services both A and B systems. Another alarm could prove confusing to the operator.

6. . In section 21 on P601, " CST Water Level Low" is a misnomer it should be RCIC tank. (A.3.12)

Corrective Action Annunciator tile is ncw labeled "RCIC Storage Tank Level Low".

63 .

JA-4. -CONTROLS

1. The useLof the'RHR B Shutdown Cooling Suction Valve 1 Ell-F006B was.not apparent to' operators. Remote Shutdown Panel. (A.4.1)

. Corrective Action

-The :use of this valve is to allow the isolation of the RHR B HX

'from-shutdown cooling if the Control Room must be evacuated.

.The' labeling-of this valve has been improved to enhance operator action. It-reads "RHR B Shutdown Cooling Suction Valve E12-F006B".

L 2. - .There is little use of knob-coding on the Remote Shutdown

=

Panel. (A.4.2)

Corrective Action '

Throttle' valve' controls on the Remote Shutdown Panel (and in  ;

the Main Control Room) have been distinguished from " fixed position" controls by using the abbreviation "THROT" on their label.

3. There is not-distinctive shape or color coding of controls for >

throttleable valves. (A.4.3)

Corrective Action Throttle valve controls on the Remote Shutdown Panel (and in the Main Control Room) have been distinguished from " fixed' position" controls by using the abbreviation "THROT" on their 1 label . -

4.- Some pushbuttons light up when depressed. However. not all of these have lamp test capability. (A.4.4)

Corrective Action ,

All lamps with testing capabilities'shall be tested periodically . Most backlit pushbuttons are lit with two bulbs '

and when lit, shall be checked aeriodically for both bulbs operable. Other indicating ligits will have indirect functional checks (i.e., if breaker is energized, at least one light will be lit, otherwise the operator will investigate).

If in doubt,' the. operators can change the bulbs to verify operability. A?1 the above items will be administratively controlled.

1

4 LA-4'. CONTROLS (Continued)'

5. An administrative control should be employed for key lock h controls'on,P801'and other panels including storage of keys.

(A.4.5) -

I -Corrective' Action CPS Procedure.1432.01, Operations Department Key Control,- I 1 outlines the-administrative controls for all keys including -

keys for key lock-controls.

l6. -On P601 insert 16, the_" Norm" j-handle position on the HPCS WATER LEG PUMP is. ambiguous. (A.4.6)

Corrective Action New labels have~been installed without the " Norm" position

' indicated.

7. On P601 insert 17, the " Neutral" j-handle position is I ambiguous.

(A.4.7)

Corrective Action-  ;

New labels have been installed without the " Neutral" position

-indicated. >

_8. Several of the Bailey controllers in the Control Room appear to have<the Manual and Automatic-control positions reversed.

There is an inconsistency from control to control. i Exampless.

a) -RECIRC Loop A Flow Control on-P680-04 i

.b) RECIRC Loop A Master Control on P680-04 '

c) RECIRC Loop'A Flux Control on P680-04 ,

d) RECIRC Loop B Flow Control on P680-04 (C . 4'. 7)

Corrective Action  ;

All the Bailey controllers follow,the same. convention. Foxboro i controllers, which are also used in the Control Room, have the  ;

. manual and automatic positions reversed in relation to the i Bailey controllers.- This deviation from the convention is countered by labeling and color coding.- The manual and automatic positions of both types of' controllers are

consistently color coded and clearly labeled to identify their l . function. his should be adequate to enhance operator action.

l l

~

A-4. CONTROLS (Continued)

9. The Manual and Automatic positions on several Bailey controllers on P680-03 are inconsistently color coded.

Examples:

a) RECIRC LOOP A FLOW CONTROL b) .RECIRC LOOP A MASTER CONTROL

.c) RECIRC LOOP A FLUX CONTROL d) :RECIRC LOOP B FLOW CONTROL (C.4.9).

Corrective Action All the Bailey controllers follow the same convention. The Foxboro controllers used in the Control Room have had the pushbutton lens changed so that manual and automatic have the same color convention as the Bailey controllers.

10. Labels on backlit indicator lights in the Control Room are easily removeable and are interchangeable. The labels do not have location identifier codes or keys to prevent interchanging the labels or to identify the correct location of each label.

Example:

UNIT 1 DMPR MTR on P801-66 (C.4.10)

Corrective Action A set of panel front elevation drawings will be available for use in the Control Room. These drawings can be used to confirm proper pushbutton conventions.

-A-5. DISPLAYS'-

1. -The informational transilluminated displays on the upper right of each section on P801 are missing some tiles. (A.5.1)

Corrective Action The missing tiles on P801 have been installed.

2. -On-P870 insert 52, the 6900 V Bus 1B Voltage scale is limited to 5250. (A.5.2)

Corrective Action A new meter has been installed with a scale range of 0-9000 volts.

3. The meter for DGB Output Watts for diesel generator output on P601 is scaled to 27.5 Kilowatts. (A.5.6)

Corrective Action A new meter has been installed with scale range of 0-5800 Kilowatts. Generator rated power is approximately 3900 KW.

4. The DGlA & IB OUTPUT WATTS meter.on P877 has a scale reading from 0 to 27.50 with increments at 4.58, 9.17, 13.75, 18.33, and 22.92. (A.5.7)

Corrective Action A new meter with scale range of 0-5800 Kilowatts has been installed with readily interpretable major and minor division markings.

5. The OS AIR TEMP RAD MON DIV 2 RAD LVL Meter on P800 has a scale reading .01 at the bottom with zero above it and increments of 10 to 100 above the zero. This also applies to DIV 1. (A.5.8)

Corrective Action Meter scale has been changed to a log scale with a range of

.1-10,000 mr/hr.

6. Suppression pool level meter on C61-P001 has a scale ranging from -24 inches to +6 inches. This scale is not consistent with similar Control Room indication, and reference point is unclear. -(A.5.9) i Corrective Action L Scale has been changed.to have a range from -45" to +55". The "0" on the~ scale represents a plant elevation of 731'5". The l final dispositionlof this instrumentation will be presented in l the DCRDR Summary Report.

l-u_

A-5. DISPLAYS (Continuad)

7. On the Reactor Water Level Recorder on P678, the scales appear incorrect for Wide Range values. (A.5.10)

Corrective Action The scales on this recorder have been changed. The red pen will monitor UPSET RANGE with a 0-180 inch scale, and the blue pen will monitor NARROW RANGE with a 0-60 inch scale. The recorder and pens have been labeled appropriately.

8. The scale for JET PUMP FLOW on the JET PUMP FLOW / CORE PLATE DP Recorder'on P678 is not high enough for the operating

' parameters. (A.5.ll)

Corrective Action Recorder scale of 0-100 mlbs/hr is correct. Normal operating flow rate is 84.5 mlbs/hr.

9. There are several meters that display mid-scale indications if the meter fails or becomes inoperative.

Examples:

a) Battery Current meters on P877-15 fail to the +200 amp indication.

b) The 4571 VARS meters on P870-15, P601-14X, and P601-15Y fail to a zero indication at mid-scale.

Corrective Action Meter fail points on meters that fail at mid-scale points will be marked in red with the letters " FAIL POINT".

10. The small meters on the Bailey controllers on P870-54M are not labeled to identify what parameter is being indicated or the units of the parameter being displayed. (C.5.6)

Corrective Action These meters have been labeled to identify both the parameter and its associated units.

11. On P601 insert 18, the Suapression Pool Level chart recorder is i

scaled in incher (0-80) while the procedures reference SP level in feet. (A.5.12)

Corrective Action Illinois Power's Engineering Department is currently reviewing Suppression Pool Level instrumentation in the Control Room to assure appropriate scales and reference points will be consistent. The final disposition of this instrumentation will be presented in the DCRDR Summary Report.

A-5. DISPLAYS (Continued)

12. The scale on the COND BSTR PUMP DISCH HDR PRESSURE on P870 has a range reading from 0 to 200 (Insert #57), which is an inadequate range for operation. (A.5.13)

Correctiv3 Action The scale has been changed to 0-800 psig, rated operating pressure is approximately 490 psi.

13. Steam Flow /Feedwater Flow scales on P678 show a range that is too small for the actual operating values. (A.5.14)

Corrective Action The scale range on the Steam Flow /Feedwater Flow recorder is 0-20 mlbs/hr, rated operating flow rate is 12.4 mlbs/hr. New chart paper has been installed to match this range.

'14 . The CCW PUMPS lA, 1B, 1C Current meters on P801 should not show negative values.. (A.5.15)

Corrective Action The scales have been changed to eliminate the negative values.

15. Readability of instrumentation on P678 from the P680 position is difficult without the assistance of banding (i.e., at 120" letter height would have to be .48" to be reads no labels or scale. numbers are larger than .25"). (A.5.16)

Corrective Action Illinois Power's Operations and Engineering Departments have reviewed this situation and have identified appropriate instrumentation throughout the, Control Room to be banded, the zones to be banded, and the appropriate color of the bands.

Banding has been added in accordance with this evaluation.

16. -MAIN STOP VALVE POSITION GROUP MILLIAMP METERS on P678 have a scale from 20 to'0 to 20. Positive and negative indications are not~shown. (A.5.17)

Corrective Action Positive and negative indication has been added.

A-5. DISPLAYS (Continued)

17. Some strip chart recorders do not have chart paper installed.

(C.5.9)

Corrective Action Strip chart recorders have appropriate paper installed. To aid the operator.in replacing recorder paper, the type of paper has been marked on the recorder door.

18. The scales on some strip chart recorders do not match the scales on the recorder chart paper.

Example:

The ECC SPEED & CONT VLV POSITION recorder on P870-59L has two scales on the recorder, and the chart paper installed on the recorder has three scales.

(C.5.10)

Corrective Action The appropriate paper with scales to match the recorder scales has been installed in all recorders.

19. The PMS TREND recorders 1 & 2 on P680-10E and the NEUTRON MONITORING SYSTEM strip chart recorders on P678 have multiple scales which are not aligned with each other or with the chart paper. (C.S.11)

Corrective Action A 7 propriate paper with the scales aligned has been installed in the recorders.

20. A vertical series of 8 pairs of red and green indicator lights on the Remote Shutdown Panel alternate colors left-right down the two columns. In this arrangement, color and position do not provide any type of redundant information and do not conform to the Close/ Green /Left - Open/ Red /Right convention used in the Control Room. (C.5.15)

Corrective Action The lights have been changed to conform with the Close/ Green /Left and Open/ Red /Right color convention.

21. One indicator needle on the steam control valve on the turbine control panel, P680, is very small and difficult to see.

(A.5.18)

Corrective Action 1 l

Meter needle will be adjusted if possibles if not, it will be l replaced with a larger one, i

A-5. DISPLAYS (Continued)

R22. Tolerance zones are not indicated on most meters in the Control Room. .( A. 5. 20)-

Corrective Action IP's Operations and Engineering Departments have reviewed this situation and.have identified appropriate instrumentation throughout-the Control Room to be banded,Lthe zones to be banded, and the appropriate color of the bands. Banding has been added in accordance with this evaluation.

23.-- .There should be some way to positively diagnose a failed indicating light. Currently, there is no lamp _ test capability to'do so. (A.5.21)

Corrective Action All lamps with testing capabilities shall be tested periodically. Indicating lights will have indirect functional checks, (i.e., if breaker is energized at-least one indicator light will be-lit, otherwise the operator will investigate).

If in doubt, the operators can change bulbs to verify operability. All the abose steps will be administrative 1y controlled.

24. Recorders are not always clearly marked-with type of paper required. They should also provide appropriate chart paper. t (A.5.22)

Corrective Action Chart paper manufacturer and catalog number will be installed inside recorder doors.

25. -The red zone marking on the GEN HYDROGEN PURITY meter on P870-55M obscures the minor division marks on the meter scale.

(C.5.16)

Corrective Action An Engineering evaluation was performed and has revealed that the system is not operated in the red zone, and therefore, should not be detrimental to any operator action. The red zone is'an' indication of danger from low hydrogen purity.

Part B This section contains items which IP had committed to perform an evaluation of in order to resolve them prior to licensing. Following each item is a statement of Illinois Power Company (IP) corrective action. Some items, as indicated, will be further evaluated as part of the Detailed Control Room Design Review (DCRDR). The results of the evaluation, proposed corrective action, and schedule for implementing the actions will be submitted as part of the DCRDR Summary Report not later than 120 days prior to issuance of an operating license.

B-1. CONTROL ROOM WORKSPACE

1. Passageways between P800, P801 and P870, P877 respectively are 26" wide; passageways between P680 and P601, P870 respectively are 27" wide. (A.l.1)*

Corrective Action The Control Room is a vital security area where key card access will be used. A CPS procedure will allow the Assistant Shift Supervisor and Control Room Operators control over who and when someone is allowed in the operating area, thus restricting the traffic flow between panels. Therefore, current passageways are acceptable.

2. There is inadequate separation between the front surface of the Remote Shutdown Panel and the backpanel surface of the adjacent electrical panel. The distance between the opposing surfaces is approximately 32 inches. This is an inadequate amount of work space for easy operation of the Remote Shutdown Panel by one or more operators. The minimum recommended separation distance between a single row equipment panel and a wall or other opposing surface is 50 inches. (C.1.1)

Corrective Action The Remote Shutdown Panel has been rotated 180 degrees and there now exists a 48" distance between opposing surfaces.

This separation distance has been considered acceptable by the NRC's Human Factors Engineering Branch.

• Throughout the report the use of parentheses, such as (C.1.2), refer to the part, section, and finding number used in the HFEB Control Room Design Review / Audit report, dated December 3, 1981.

t' 3 B-1. CONTROL ROOM WORKSPACE (Continued)

3. The J-handle Transfer Switches on the Remote Shutdown Panel are mounted too low. They are located between approximately 20" and 33" above the floor. This low control height makes them inconvenient to operate. (C.1.2)

Corrective Action The transfer switches on Remote Shutdown Panel (RSP) are used only to transfer control functions from the Main Control Room to the RSP. Therefore, they are actuated once and left in this position while operations are performed at this panel. Due to this infrequent use, they are positioned relatively low and out of the way to allow the frequently used controls and displays to be optioally positioned on this panel.

'4. The shiny surface of control pushbuttons and CR2 40 switches results in glare (9.5:2.6 against panel background). (A.l.6)

Corrective Action This will be reevaluated as part of the Detailed Centrol Room Design Review (DCRDR) after completion of lighting installation.

5.. The keyboard for the PMS System on P680 has significant glare which obscures the legends. (A.l.7)

Corrective Action This will be reevaluated as part of the DCRDR following installation of permanent lighting.

6. The minimum reading distance for meters should be seven feet.

The glare problem makes this difficult. (A.l.8)

Corrective Action This will be reevaluated as part of the DCRDR after permanent lighting and " egg-crate" diffusers are installed.

7. Significant glare is occurring on all meters in the Control Room. (A.l.9)

Corrective Action This will be reevaluated as part of the DCRDR after permanent lighting and " egg-crate" diffusers are installed.
