SUMMARY

FCREWORD -
NUREG-0737 Supplement 1, Section 5.lb requires that a Control Room Design Review (CRDR) be conducted to identify human engineering discrepancies (HEDs). Section 5.lc requires that these discrepancies be assessed and design improvements selected to correct these discrepancies.
Public Service Company (PSC) has conducted the required review of the Fort St. Vrain Control Room. Approximately eight hundred forty eight (848) discrepancies or classes of discrepancies were cited. These discrepancies were assessed to determine their potential for causing an operating error and the potential effect of any error. (Certain discrepancies are known to have caused errors). An improvement program has been selected which meets the regulatory requirements and proposes to improve the operability and functionality of the Control Room.
The regulatory requirement for the CRDR and the follow-on .mprovement program was directed toward the improved handling of emergencies and not specifically toward improved production. Public Service Company's improvement program is directed toward both normal operation and the handling of emergencies.
BACK3ROUND - Public Service Company has initiated an integrated improvement program based on functionality rather than particular classifications of problems. This approach is first, one of determining functional groupings, followed by demarcating, hierarchical labeling, correcting indicator scaling, complying with established conventions (color coding, switch positions, etc.).
The following steps constituted the planning portion of the integrated improvement program.
Elevation Drawings of each control panel were color coded to show applicable HEDs as either, relabeling, relocations, scaling, deletions, or equipment changeout. This scheme provides an overview of the problems documented on each control board.
- All HEDs involving Alarm Locations, and multipoint alarms were reviewed. System function and operator response were considered I in grouping, deleting and adding alarms.
I Paste-ups of all alarm panels were completed to show proposed rearrangements.
- Functional grouping of controls and indications was approached by first preparing point interaction sketches for various systems or by direct reference to system P&Is. This effort was, in effect, an extensive operational analysis which considered the dynamic considerations of control groups and 1
r Ib arrangements. This activity reviewed the
' purpose and use of each and every component on the main control boards. Interviews with operators and training personnel were conducted to determine operator interpretations and actions.
- Controls and indications were then arranged in functionally related groups. Associated alarm locations were rechecked to verify that the more desirable locations were selected. The function relationship of adjacent indicator and control groupings were reviewed.
- Revised drawings were prepared to show the proposed arrangements. Certain of these drawings were color coded to aid in differentiating between groupings. These drawings were then utilized to determine the scope of each change package (change notice).
- Change Notice (CN) numbers werer assigned to each effort identified abover IMPROVEMENT PROCESS METHODOLOGY The Improvement Process starts with tha documentation and drawings produced during the improvement planning process described in the BACKGROUND presentation portion of this summary. An individual designer was assigned the responsibility of evaluating controller operating conventions. An educational process was initiated to acquire a thorough understanding of each controller's function within the system. System descriptions, Piping & Instrument diagrams, electrical drawings, and operating procedures were studied to gain this thorough understanding.
All HEDs applicable to particular controllers weri reviewed and the tentative fix evaluated for its corrective value within the integrated approach. HEDs written against controllers recorded by the Emergency Operating Procedure task analysis "Information and Control Requirements" effort, were reviewed with particular attention to any potential safety considerations. Any previously prepared investigative information was studied. All factors were evaluated in considering any changes to the controllers.

l SPECIFIC - Standardizing Controller Operation - (Change Notice (CN)-
1918 preparation package.)
Research - CN-1918 was generated to standardize controller operation and correct controller discrepancies identified by HEDs. Existing controller operation and human factors material was researched to define an operating stereotype for controllers. The following operating conventions were defined and provide the basis for the evaluation of controller problems.
l
- 1. Controller's operating labels will indicate the parameter controlled.
- 2. Controller operation will be OPEN/ INCREASE to the right and CLOSE/ DECREASE to the left.
- 3. Setpoint dials will operate such that the numbers increase as the dial is rotated counter-clockwise.
- 4. Setpoint dials for the bias controllers will have a bipolar scale and will have adequate resolution to allow for the required degree of control.
Design - Each Model 62H controller was evaluated using the operating conventions defined above. The following four (4) points summarize the proposed corrective actions (and in the case of bypass controllers, the basis for not making any change).
- Relabeling the controllers to indicate the controlled paramater will resolve many of the cited discrepancies.
Certain controllers will be modified such that the manual action and the set point dial operate according to the defined stereotype.
- The setpoint circuit for the bias controllers will be modified to allow for higher resolution on the setpoint dial.
- The bypass controllers will be left as is. A
" bypass" controller provides an alternate control signal source to bypass a faulty controller. The operating convention of a
" bypass" controller is one of increasing currant output by rotating clockwise. This convention may differ from the function specific controller being bypassed.
i t
l,
4 The Foxboro Specification 200 controllers were identified as having the following problems:
- Lack of anti-wind up function.
- The lever-action is restricted by a detent pin.
- The T-bar lever is too small.
- The presence of discrete indicating lights on the controller face which do not conform to a standard.
These controllers will be replaced with Foxboro H-Line controllers to correct these discrepancies.
PDC-31207 and FIC-3151 both have unique controller actions for which a nameplate light will be added to identify this action to the operators.
The following Design Directives apply to the re-design of I-01 control board:

SUMMARY
OF THE CONTROL ROOM IMPROVEMENT DESIGN PROCESS AS APPLICABLE TO RECORDER SCALE AND PAPER e
FOREWORD - NUREG-0737 Supplement 1, Section 5.lb requires that a Control Room Design Review (CRDR) be conducted to identify human engineering discrepancies. Section 5.lc requires that these discrepancies be assessed and design improvements selected to correct these discrepancies. Public Service Company (PSC) has conducted the required review of the Fort St. Vrain Control Room. Approximately eight hundred forty eight (848) discrepancies or classes of discrepancies were cited. These discrepancies were assessed to determine their potential for causing an opr.ra ting error and the potential effect of any error. (Certain discrepancies are known to have caused errors). An improvement program has been selected which meets the regulatory requirements and proposes to improve the operability and functionality of the Control Room. The regulatory requirement for the CRDR and the follow-on improvement program was directed toward the improved handling of emergencies and not specifically toward improved production. Public Service Company's improvement program is directed toward both normal operation and the handling of emergencies. BACKGROUND - Public Service Company has initiated an integrated improvement program based on functionality rather than particular classificatinns of problems. This approach is first, one of ' determining functional groupings, followed by demarcating, hierarchical labeling, correcting indicator scaling, complying with established conventions (color coding, switch positions, etc.). The following steps constituted the planning portion of the integrated improvement program. Elevation Drawings of each control panel were color coded to show applicable HEDs as either, relabeling, relocations, scaling, deletions, or equipment changeout. This scheme provides an overview of the problems documented on each control board.
- All HEDs involving recorder locations, and multipoint recorders were reviewed. System function and operator response were considered in grouping, deleting and adding recorders.
Paste-ups of all recorder panels were completed to show proposed rearrangements.
- Functional grouping of controls and indications was approached by first preparing point interaction sketches for various systems or by direct reference to system P&Is. This effort was, in effect, an extensive operational analysis which considered the dynamic considerations of control groups and
arrangements. This activity reviewed the purpose and use of each and every component on the main control boards. Interviews with operators and training personnel were con-ducted to determine operator interpretations and actions. Controls and indications were then arranged in functionally related groups. Associated recorder locations were rechecked to verify that the more desirable locations were selected. The function relationship of adjacent indicator and control groupings were reviewed. Revised drawings were prepared to show the proposed arrangements. Certain of these draw-ings were color coded to aid in differentiating between groupings. These drawings were then utilized to determine the scope of each change package (change notice). Change Notice (CN) numbers were assigned to each effort identified above. There are types of problems or concerns applicable to specific types of controls or indications which are more effectively addressed as a single effort rather than being addressed as part of each control board. The Recorder Replacement / Relocation (CN-1878) and the Recorder Scale and Chart Coordination are such efforts. CN-1878 design analysis (submitted as " Attachment 6b-7") replaced and combined a total of 38 recorders into new models. Certain recorder functions were combined, resulting in fewer recorders. Nineteen of these were placed on the I-09 panel and one, TR-2321, was relocated outside the control room for functional grouping. CN-2177 was reserved to address Recorder Scale and Chart problems. IMPROVEMENT PROCESS METHODOLOGY The Improvement Process starts with the documentation and drawings produced during the improvement planning process described in the BACKGROUND presentation portion of this summary. An individual designer was assigned the responsibility of evaluating recorder problems. System descriptions, Piping & Instrument diagrams, electrical drawings, and operating procedures were studied to gain a thorough understanding of each applicable system and the basis for recording certain parameters. Where the responsible designer was unable to establish the need or basis for reccrding certain parameters, operating and training personnel were interviewed to solicit operational philosophies. The
Operational value and function of each recorded parameter was addressed. Informational requirements were again discussed. (This informational requirements effort is in addition to that conducted for Emergency Operating Procedures task analysis). In certain cases, operators were asked to list those recorder points and the specific information required from those points to make an operating decision. This information was evaluated in making the determination to provide alternate indication or to relocate the recorder. All HEDs applicable to Recorder Scales and Charts were reviewed and the tentative fixes evaluated for corrective value within the integrated approach. HEDs written against recorders listed by the Emergency Operating Procedure task analysis "Information and Control Requirements" effort, were reviewed with particular attention to any potential safety considerations. Any previously prepared investigative information was studied. All factors were evaluated in considering any changes to the recorders. SPECIFICS - Recorder Scale and Paper - (Change Notice (CN)-2177 preparation package.) Research - HEDs citing recorder scale and chart problems were each grouped into one of three categories:
- 1) General, which includes:
Recorder range is incorrect for parameter range. Recorded range does not agree with alternate indication. Current data is not readily accessible (i.e., visual exposure of printed area is delayed by obstruction). The fixed scale and chart are different. Recorded format does not meet operating requirement, i.e., required rate of change n displayed amplitude value.
- 2) Scale and Chart which includes:
Readability. Does not conform to the standards set forth in DD-AIS-1 for scales. l
- 3) Labeling problems which include:
Pen color assignments are either incorrect or do not exist. Functions for multi points are not posted or listed. Conceptual Design - After reviewing the HEDs and categorizing the cited problems, redesign proposals were considered. The operational relationships were evaluated to make certain that the fix provided the best man-machine interface. Scale and paper problems were in part addressed by submittal
" Attachment 6b-7". This synopsis presented the concept of relocating certain recorders to a back panel (and supplying needed information in a more useable form) and the replacement of certain recorders with new models selected with attention to readability.
The various types of discrepancies previously cited are to be corrected as follows: The range of the recorder will be adjusted such that it is correct and agrees with alternate indication, or a means of displaying the required data in a more direct form will be provided, i.e., replace the existing recorder or provide a digital or analog indication of the data. Replace either the scale or chart such that the two correspond. Scales will be replaced to ensure readability and conformance to DD-AIS-1. A pointer will be added to the Foxboro reco ders. Recorders will be labeled to indicate the correct pen color assignments and the functions for the multi points will be posted and listed. The replacement of complete recorders with new models selected in accordance with Design Directive DD-RSN-1. The use of selectable digital (or analog) indicators to provide operators with needed information in a more direct and readily useable form. The following recorders were reevaluated and the cited discrepancies were determined to be invalid: HED-0653: NR-1133-2 was cited as not having an index scale and/or scale pointer and/or appropriate markings for the parameter being measured and/or process unit consistent with the intended use. The recorder is for Power Range Flux Level. It is scaled from 0-150 percent which is consistent with alternate indication. The recorder has a pointer. The fixed scale and chart correlate and the process unit, percent, is on both. Therefore, no further action is required. HED-0655: NR-1111/NR-1133-1, NR-1131-1/NR-1134-1 were cited for scales not being clearly readable and resolvable from the operating position. Although the scales on these recorders are adjacent to each other, the pointers (2) for each recorder are positioned such that one indicates from the top of the dual scale and the other from the bottom allowing for easy interpretation of the reading. Therefore, no further action is required. The following Design Directives apply to the redesign of. recorder scales and charts: NUMBER ISSUE DESCRIPTION DD-AAS-1 A ABBREVIATION, SYMBOL, AND ACR0llYM SELECTION DD-LAB-1 B PANEL AND COMPONENT LABELING DD-AIS-1 ANALOG INDICATORS DD-RSN-1 RECORDER SELECTION -

SUMMARY
OF THE I CONTROL ROOM IMPROVEMENT i DESIGN PROCESS i AS APPLICABLE TO l I-9349/B SECONDARY COOLANT MONITORING PANEL l i b i I l
~
FOREWORD - NUREG-0737 Supplement 1, Section 5.lb requires that a Control Room Design Review (CROR) be conducted to identi fy human engineering discrepancies. .. Section 5.1c requires that these discrepancies be assessed and design improvements selected to correct these discrepancies. Public Service Company (PSC) has conducted the required review of the Fort St. Vrain Control Room. Approximately eight hundred forty eight (848) discrepancies or classes of discrepancies were cited. These discrepancies were assessed to determine their potential for causing an operating error and the potential effect of any error. (Certain discrepancies are known to have caused errors). An improvement program has been selected which meets the regulatory requirements and proposes to improve the operability and functionality of the Control Room. The regulatory requirement for the CRDR and the follow-on improvement program was directed toward the improved handling of emergencies and not specifically toward improved production. Public Service l Company's improvement program is directed toward both normal operation and the handling of emergencies. BACKGROUND - Public Service Company has initiated an integrated improvement program based on functionality rather than particular classifications of problems. This approach is first, one of
- determining functional groupings, followed by demarcating, hierarchical labeling, correcting indicator scaling, complying with established conventions (color coding, switch positions, etc.).
This approach was used throughout the design analysis phase for each main control board or panel. Since the objective remains the same ' for I-9349 and its auxiliary panel, I-93498, the approach for these panels varied only slightly from that of the main control boards. Panels I-9349/B are located outside the main control room and comprises an auxiliary control station from which the reactor may be shut down and critical parameters monitored. Controls on I-9349 include switches to open/close both feedwater flow valves, both main steam valves, as well as indicators for monitoring the secondary coolant parameters. IMPROVEMENT PROCESS METHODOLOGY APPLICABLE TO I-9349/B An individual designer was assigned the responsibility of evaluating I-9349/B. Since this individual had not participated in previous efforts, an educational process was initiated to acquire a thorough understanding of the system, subsystems and components represented on
! the assigned panel. System descriptions, Piping & Instrument diagrams, electrical drawings, and operating procedures were studied to gain this thorough understanding of the system and component functions.
The design analysis approach for I-9349/B did not include the use of color coded and marked-up drawings to show applicable HEDs by generic 1_ _ _ _ _ _ _ . . _ _ . , _ _ _ _ _ , . . _ . - - - _ . _ . _ . - - - , _ - , , - - . . _ _ , , - - _ . - - - -, _-,, , . e--.-

disposition titles. This was due to the relatively small number of HEDs and the distribution of problem types. Secondly, since the controls and monitoring instrumentation located on I-9349/B are redundant to and paralleled ' with the control room, a separate operational analysis was not required. (A task analysis walk-through, talk-through addressing remote Reactor Shutdown procedures was completed.) All HEDs (see Attachment A) applicable to the I-9349/B panels were reviewed and the tentative fixes evaluated for corrective value within the integrated approach. Task analysis documentation was studied and all other known factors were evaluated in considering any
- changes to I-9349/B.
SPECIFICS - I-9349/8 Redesign Synopsis - (Change Notice (CN)-2035 preparation package.) Resear;h - During this phase, System Descriptions, System Abstract, System Operating Procedures, Technical Specifications and Procedures were reviewed. Other research included discussions with operators, and engineering support personnel. This interaction with other sectors continued throughout the Research and Design phases. A review of the HEDs and a physical study of the panel confirmed problems in labeling, grouping and the physical location of controls and indications. The original panel layout is included as Attachment B. Conceptual Design - After the existing design was reviewed, preliminary redesign proposals were made using elevation drawings modified to show proposed changes. Several iterations of these drawings were used to develop a new layout that answered all of the design problems encountered during the research phase. As the functional group was defined, its operational relationships we: e evaluated to make certain that the arrangement provided the best man-machine interface. The best arrangement was determined by locating all controls and indicators relative to secondary coolant monitoring on I-9349 and all instruments relative to the reactor on I-93498. As the design became more viable and appeared to resolve most or all of the known problems, interviews were conducted to determine if all of the operational requirements were met. Sample copies of the Interview records are included as Attachment C. These interviews were conducted in the following manner:
- The final version of the proposed layout was presented to an operator.
'- m,
- The operator was asked to comment on the layout in relation to various tasks that he would perform.
Information and control needs were reviewed. , i During the Control Room Systems Review Group evaluation of this proposal, the value of a common lamp test button for all indicating lights was discussed. It was determined that an individual button for each set was not a problem and that no changes were required. The finalized proposed layout is included as Attachment D and a l summary of proposed changes is included as Attachment E. ' The final step in this conceptual design phase was to determine the text content for functional labels. Since all indicators are a duplication of indications on the main control board, the same functional labeling was maintained. (See Attachment F.) The following Design Directives apply to the redesign of I-9349/B.
