1.0 INTRODUCTION
(
As required by supplement 1 to NUREG-0737, Commonwealth Edison Company (CECO) performed a Detailed Control Room Design Review (DCRDR) for Quad Cities Station, Units 1 and 2. As required in f NUREG-0737, CECO submitted a summary report to the Nuclear Regulatory Commi'sion s (NRC) in May 1985 . This report
{ described the completed DCRDR and . outlined proposed control room changes, including the proposed schedules for implementa-tion. This report also included summary justification for human engineering discrepancies- to be left uncorrected or partially corrected. This report was tollowed by an on-site audit at Quad Cities Station during June 10-13, 1985.
f The NRC responded to this report in a letter dated August 8, 1985 ("NRC Audit Response"). The overall finding was that CECO
( had conducted a "very comprehensive human f actors review which ,
satisfies most of the DCRDR requirements of Supplement 'l to NUREG-0737." Further, the NRC stated that specific packages and reviews were needed to supplement the final summary report.
( Supplement 1 of this submittal is intended to supplement Volume
- 1. (Quad Cities Final Summary Report). It addresses the specific concerns expressed in the "NRC iudit Response" and provided a detailed description of- each package. These
( concerns include those related to methodology as well as those referring to specific corrective action responses.
(
\ .
1 Volume 2 (Parts 1-3), Rev. 1 is intended to- replace the original Volume 2 Final Summary Report submittal. This volume contains the revised corrective actions.for all HEDs in Volume 2, Rev.'O. They are organized into-Part 1 - Corrective Actions Completed; Part 2 - Response to Finding Modified; Part 3 -
Corrective Action Accepted By the NRC.

i 2.0 RESPONSE TO NRC
GENERAL COMMENT
S I
The NRC provided a list of activities, areas of improvement, and documentation required for CECO to meet NUREG-0737, Supplement l-DCRDR requirements.
The following is the NRC comment-from the "NRC Audit Response" and the respective CECO response.
- 1. Control Room Survey NRC Comment: Ensure that the revised checklist guidelines using task analysis results do not result in improvements to instrumentation used only in emergency operations that would be inconsistent with non-emergency instrumentation.
CECO Response: Where applicable, improvements to instrumentation used in emergency operations will be applied 'to all -similar instrumentation to ensure consistency. The revised checklist HEDs pertained to task. analysis HEDs. Due to the redundant DCRDR processes, HEDs regarding non-emergency instrumenta-tion were written during the operator survey and checklist.
NRC Comment: Modify the three CECO checklist guidelines discussed at the audit and restated in this paper so they will be :in accordance with the criteria of NUREG-0700. These revised. guidelines should then be incorporated into CECO's review process and applied to the Quad Cities Station control room review.
CECO Response: We concur with the NRC position and have modified the three CECO checklist guidelines as<
well as reviewed the affected HEDs.
- 2. Assessment of HEDs NRC Comment: Document the reasoning behind CECO's switch from the rating system, presented in the Program Plan to be used during the assessment phase to the consensus method that was actually used.
I; CECO Response: The switch to a consensus format facilitated the practical understanding of the impact each HED may have on operator performance. Each member contributed a unique perception to the HED which helped shape the opinion of the group. In this process, each member had- equal opportunity to influence the final decision on every HED. A rating system, however, was maintained, using a consensus rather than individual input.
NRC Comment: Document why CECO changed from the four-tiered level rating . system presented in the Program Plan to the three-tiered level rating used.
CECO Response: The original rating system utilized four significance levels: ,
Level A - HEDs which are documented errors.
i 4_
l . __. -, ,. - - . . . - - - - .. - - - - - - - - - - - - - , --- -. - - - - --
l Level B -
HEDs with an overall high significance rating.
Level C -
HEDs with an overall moderate significance rating.
Level D - HEDs with an overall minimal. significance rating.
Both Level A and B HEDs were deemed equally significant. Therefore, they were combined into a single level -
" Level A." Level C and D HEDs were then renamed Levels B and C, respectively.
NRC Corunent : Ensure the NRC staff that cost factors will not impact decisions to correct HEDs as presented by CECO at the audit since this is contrary to what was printed in the Summary Report.
CECO Response: Safety significance and operator performance were the only criteria used to assess HEDs. Cost factors were not discussed ditring assessment. Cost factors, however, do. affect the decisions for corrective actions.
NRC Comment: Ensure the NRC staff that benefit ratios as described in the Summary Report will not be applied during the assessment phase.
CEC 7 Response: Safety significance and operator performance were the only criteria used to assess HEDs. Benefit ratios were not- discussed. Benefit ratios, however, do affect the decisions for corrective actions.
NRC Comment: Provide detailed documentation for the HEDAT's justification for canceling 36 HEDs during the assessment process.
CECO Response: The Justification for canceling HEDs is provided in Appendix F. All HEDs are referenced by number in the Index of Volume 2.
NRC Comment: Provide assurance that those HEDs that have been grouped together reflect the categorization and level of the most significant HED in the group.
CECO Response: All HEDs have been reviewed and the grouped HEDs reflect the categorization and level of the most significant HED in the group.
NRC Comment: Document the reasoning for not using the Pre-assessment Form as described in the Program Plan.
CECO Response: The integration of materials onto the database management system negated the need for a separate Pre-assessment form originally discussed.
Code numbers representing specific (human factors) problems and consequences were incorporated directly on the HED form before the assessment. The coding system is shown in Appendix G. In addition, the HED form has been updated and is provided on pages G-3 and G-4.
- 3. Selection of Design Improvements NRC Comment: Complete the studies and reviews listed in ~ Appendix D (of the NRC letter). Provide the NRC with a description of the design packages that result from these studies and how these results will be used to correct the control room discrepancies.

i CECO Response: This information is provided on the affected HEDs. For those HEDs where standards were required, the information regarding the standard is provided in Section 4.0 of this report, and the specific standards are provided in the' Appendices.
NRC Comment: Resolve the inadequacies in the proposed corrective actions and justifications for not taking corrective actions for the HEDs specified in Appendix A of this (the NRC letter) report.
CECO Response: All issues in Appendix A of tne NRC letter have been addressed. Section 3.0 provides a cross-reference by NRC section of the corrective actions for Quad cities.
- 4. Coordination of Control Room Improvements NRC Comment: Provide to the NRC a diagram of the station's coordination program. This flow diagram should be accompanied by a detailed functional explanation.
CECO Response: The station's coordination program is-stated in CECO's response to Supplement 1 of NUREG-0737. The cited flow charts are in-house documenta-tion used by Ceco as a working tool. The chart is constantly upgraded and revised and only used as a guidance document.

The responses to these discrepancies should further clarify issues concerning operational or behavioral factors and address the topic of cumulative and interactive effects.
CECO Response: The nature of the cited computer HEDs are inconsequential. The cumulative effect of the HEDs would only be. critical in a computer sophisti-cated environment such as production where individuals
, rely on the computer on a continuous daily basis. The control room computers are used only as backup infor-mation. The primary information consists of control room instrumentation.

APPENDIX B CONTROL ROOM LABELING STANDARD QUAD CITIES i
I t
t B-1 1
CONTROL ROOM LABELING STANDARD The ' characteristics of labels must be such that they provide maximum information to the operator. The various illumination levels of control areas, control locations, and restraints on operator position demand that all label characteristics (such as size, lettering and plicement) serve as perceptual aids to information discrimination and processing. The redundancy inherent in such characteristics can serve as a visual code to reduce response time and minimize probability of error.
Placerent of labels should be uniform throughout the system to insure ease of element / control identification and should provide maximum visibility. Labels should be oriented horizontally in order to be read easily, quickly and accurately
)
and should not be subject.to accidental removal.
, The following guidelines adhere to those established by the CECO checklist to aid the operator in locating, identifying and handling controls, displays and equipment.
- 1. Label Information .- Labels should describe the function of equipment items, or if .needed for clarity, describe engineering characteristics or nomenclature.
- 2. Placement of Labels -
Labels should be placed -below indicators and above controls except in cases where there i
- are space constraints. All labels should be placed close to the corresponding panel element. Placement should also '
I 1
l B-2 ;
l f
provide sufficient space to allow adequate discrimination from adjacent -controls and minimum interference with visibility during adjustment or manipulation of controls.
Placement should also be such that labels do not obscure or detract from other information sources (see Figures 1 and 2). Therefore, the following guidelines should be followed:
l a. Labels should not appear on the control itself when an adjustment or manipulation is required that causes the t
operator.'s hand to obscure the label for an extended i time period. ,
2
- b. Adjacent labels should be separated by sufficient 1 space so they are not read as one continuous label (see Figure 3).
i
- c. Eliminate, wherever possible, vertically oriented labels and replace with horizontal labels, '
i
! d. Curved patterns of labeling should be avoided.
- e. Labels should be mounted to . minimize the possibility f
1 of accidental detachment.
l f.
Labels should be rnounted on a flat surf ace. l 5

CONTROL ROOM ANNUNCIATOR STANDARD The guidelines governing the labeling of annunciator warning systems parallel the labeling guidelines for the control room.
- 1. Location - The alphanumeric labeling of the vertical and horizontal axes of the annunciator' panels should be consistent with a subtended visual angle of at least 15 minutes viewed from a central position within the primary operating area. For Quad Cities, this should be .5 inches. Within each panel, alarm tiles should be grouped by function or system, and each panel should be located above the related controls or displays necessary for diagnostic or corrective response.
- 2. Legends - Legends on individual annunciator tiles should be unambiguous and specific as to conditions that they address. Information should be conveyed concisely using abbreviations and acronyms consistent with those used elsewhere in the control room. The use of alarms which refer to other detailed annunciator panels located outside the primary operating area should be minimized.
3.. Character Height - For optimum legibility of the panel legends, letter height should subtend a minimum visual angle of 15 minutes and be identical for all tiles based on maximum viewing distance. For Quad Cities, the letter height should be .22 inches.
l i
C-2 1.
- 4. Character style - Type style for legends should be simple, upper-case, and consistent for all tiles to insure maximum readability. Legends should 'be engraved on tiles using black lettering on white background to provide high contrast.
Character ratios should be consistent with those recommended in the labeling standard. Specific dimensions are shown in Table 2.

COLOR CODING STANDARD In selecting new uses for color in the control room, the following rules should be considered:
- 1. The number of colors employed should be kept to the minimum necessary to provide adequate information and should provide high- contrast relative to the background area of the display.
1 2.- There should be consistent use of meaning for each color.
+ 3. The color should be recognizable in various lighting conditions.
General Guidelines - The following information is a summary of recommended human factors engineering principles and practices to be used in the inplementation of color in the control room:
- 1. Visual coding improves operator performance by v
pro'iding immediate discrimination of information during normal monitoring procedures and by reducing response time to critical cituations.
- 2. Color coding of functional relationships will be used to present qualitative information. accurately and quickly without requiring the operator to cognitively interpret or relate such information to system or component functions. Such codes will be used to particular advantage in circumstances which require search and location of information. (See Appendix E).
D- 2
- 3. The use of color in the control room will include:
e Annunciator prioritization (red = first out, green =
non-critical, white = all others) e Mimics (on electrical panel
- Division 1, 4KV = dark blue q - Division 2, 4KV = light blue
- Division 1, 480V = dark green
- Division 2, 480V = light green (all other panels)
- black t
e Indicator lights - See Table 1
- 4. The .following rules will be considered for color t
coding:
- a. For optimal effectiveness, color codes represent redundant information: The color provides a
, perceptual alerting which meaningfully represents information available in some other mode as location, orientation, or scale markings.
- b. The response benefits inherent in color coding system information depend on the ready
- discriminability of such codes and the ease with which they can be learned.
'5. -The following considerations are offered as a guide to i
the effective use of color in the control room:

Permanent markings will be applied to the meter surface (not to the glass or plastic casing) after proper ranges have been established. Zone markings will be. applied to scale surfaces during calibration. A heat-resistant, transparent acetate material such as Formaline brand charting tape will be used for zone markings.

Twenty-four colors will be applied across all control boards for backgroundashng. di B.
_ BACKGROUND SHADING In general, function. In controls the few casesand displays were found to be grouped by where components separately from similar are grouped componcnts, background shading affords a means by which to functionally group them.
contrast colors were selected Relatively higher relatively short distances. in these cases to compensate for their related components Both the main component group and in a identically. system will De colored Background shading will be applied to component groups that are functionally by independent related but where that function was inputs. accomplished Background shading facilitates the distinction by the application of different values and chroma of the same hue (see pp. E-6 through E-16).
In general, been designed the selection to work and use of background shading has in concert the placement design of instruments. with other perceptual aids and The total-board design evaluationaids.

~ -
Twenty-three systems or control / display groupings per unit including those common to both units will be background !
shaded. The attachment identifies each system by panel, panel section, and the location numbers of components. Color code numbers correspond to those appearing on the panel elevations.
Also, Munsell notations are given. The Munsell notations are statistically derived universal color standards that reference the three dimensions of color, i.e., hue, value and chroma and is used for developing design specifications. The equally spaced color scales are convenient for expressing the perceived color of an object and the color differences observed among a grou.p of objects.
C. MIMICS Lines: 3/8" wide Color: See color standard (Appendix D)
Arrow: Should be engraved and filled with white plastic. The engraving is for perma-nence of the markings and the filling keeps the engraving from being obscured by dirt. Arrows showing direction of flow should be spaced every 5 inches and within 2 inches of junctions and termi-nations.
Cross-overs: Where mimic lines cross, but the pipes or wires represented do .not have a junction, spacing between'the continuous '
line and the discontinuous line should be between 50 and 80% of the width of the mimic line (Figure 1).

Responses on the operator survey indicate'a need for ECCS pump discharge pressure gauge in the MCR' (e.g., RHR and .RHR SWP pumps). These gauges would provide positive feedback on the status of the ECCS systems, that is, whether the pumps are running. Other indicators show demand, but not s t a t'a s .- Thus, , the pressure gauges would provide an alternative method of verifying that the pumps are running. JUSTIFICATION FOR CANCELING: There are currently ways of telling if the pumps are running. Readings . are taken locally of major equipment which is needed to be operated in the area.

HED INDEX NO.: 0268 HED NO.: 1.1.1.B/OS-6 FINDING: The operator survey indicated a need for off gas temperature and pressure indicators in the MCR so that the operator could monitor them ~ more frequently. In emergency situations, it would be critical for operators to monitor off gas temperature and pressure frequently which is not feasible with the current configuration. 1 1 JUSTIFICATION FOR CANCELING: t j The operators do not need this information during operations. 1 d 4 i j '4652/c/78 i F-17

Operators ( need to base their actions on current information on the status l of valves in systems and the computer would provide a reliable l and rapid method of doing so. This can be extremely useful in emergency condit' ions. Moreover, many valves in the building are locked _in a position and the operator has no indication in ! the MCR except by talking with an equipment attendant sent there. l~ r JUSTIFICATION FOR CANCELING: Lights located in control room provide adequate information. } i I i 1 1 1 i 4652/c/81~ s l F-20 l
