SUMMARY
OF THE CONTROL ROOM IMPROVEMENT DESIGN PROCESS AS APPLICABLE TO I-03/04 1

, FOREWORD -
NUREG-0737 Supplement 1, Section 5.lb requirss that a Central Room Design R; view (CRDR) be conducted to identify human y cngine: ring 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 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 Company's improvement program is directed toward both normal operation and the handling of emergencies.
BACKGRDUND -
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 1roupings, followed by demarcating, hierarchial labeling, cc recting 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 changeof This scheme provides an overview of the preolems documented on each control board.
- All HEDs involving Alarin Locations, and multipoint alarms were reviewed. System function and operator response were considered in grouping, deleting and adding alarms.
Paste-ups o f_ 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 arrangements. This activity reviewed the purpose and use of each and every comyc ent on the main control boards. Intervips with operators and training personnel were v '
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 were assigned to each L effort identified above.
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 is assigned the responsibility of evaluating a particular board. Since this individual may not have participated in previous efforts, an educational process is initiated to acquire a thorough understanding of each system, subsystem and component represented on the assigned control board. System . descriptions, Piping & Instrument diagrams, -electrical drawings, operating procedures are studied to gain this thorough understanding of each system and component function. An operational analysis is conducted for each system and component on a particular control board. (This in-depth analysis is -
in addition to that completed for the CRDR and planning purposes.)
This Operational Analysis provides additional basis for determining any changes to functional groupings..
Operating and. training personnel are interviewed to solicit operational philosophies. The Operational value and function of each control and indication is addressed. Informational requirements are again discussed. (This informational requirements effort is in addition to that conducted for Emergency Operating Procedures task analysis).
All HEDs applicable to a particular control board are reviewed and the tentative fix evaluated for its corrective value within the
. integrated approach. HEDs written against instruments and controls recorded by the Emergency Operating Procedure task analysis ,
"Information and Control Requirements" effort, are reviewed with ;
particular attention to any potential safety considerations. Any !
previously prepared investigative information is studied. All i l
l l
l

e .
factors are evaluated in considering any changes to the control board.
SPECIFIC -
I-03/04 Redesign Synopsis - (Change Notice (CN)-1887 preparation packages.)
Research -
During this phase the systems related to I-03/04 were studied using the applicable Operations and Maintenance Manuals, as well as related system abstracts, System Operating Procedures, Technical Spe'cifications and system drawings. In addition, both the Technical Specifications and Final Safety Evaluation Report were reviewed to' determine the operational (process) control limits and >
safety interactive controls and systems for each panel.
Other research included review of operator training packages and discussions with operators, trainers, and engineering support personnel. This interaction with other sectors was continued throughout the research and design phases. A review of all related HEDs was performed and design problems reviewed. (See Attachment A).
Review of the HEDs and a physical study of the panel revealed that there were problems in grouping, labeling, viewing angles for displays, physical operational problems relating to rod operations and display monitoring, as well as poorly arranged control and display groupings. Several data presentations offered potential for improvements. The original board layouts are included a: 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 each functional group was defined, its operational relationships were evaluated to make certain that the arrangement provided the best man-machine interface.
This design provided for placement of controls and displays within a functional group and then the integration of the functional group into the board re-design and thus the control room.
In this process, several iterations of a layout were evaluated. 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 design and operational parameters were met. Sample copies of the Interview records are included as Attachment C. These interviews were conducted in the following manner:
= The final iteration of a proposed layout was presented to an operator.
- The operator was asked to describe in detail the various tasks that he would perform.
4 Particular attention was given to the functional grouping and the operational relationships of each grouping.
- Information and control needs were reviewed.
The operator was asked to evaluate the proposed labeling and scaling presentations to verify that the required information was presented in a clear, concise and readily useable format.
This " table top" analysis was conducted with various operators, shift supervisors and trainers. (See Sample Interview records, Attachment C).
This validation effort resulted in operators expressing concern over the physical placement of the Neutron Flux display location and control rod selection switch configurations. These concerns were subsequently evaluated and resulted in a relocation of the display and a reconfiguration of the Selection Swtiches. These finalized '
proposed layouts are included as Attachment D.
A summary of changes to the I-03/04 control board is presented by Attachment E.
The- final step in this conceptual design phase was to determine the final text content for functional labels. Prior operator interviews and operational analysis efforts provided the basis for tnese determinations. See Attachment F for Functional Label legends.
Re evaluation of the following HEDs indicates that number 0280 and 0736 are not totally valid. The bae' for this determination is as follows:
HED 0280 cites HS-1216 configuration. Fuel Loading is on the left position, OFF is at the top position, and Run is at the right position. This violates convention of 00-SWI-1 that OFF be on the left or CCW position. Re-evaluation of switch configuration determined that since HS-1216 provides permissives to the plant protection system (PPS) in Fuel Loading & Run position, the safest configuration is to go from 0FF to either mode.
HED 0736 states " Rod drive controls have to be held for long pericds at a time." This HED was generated from and is a logical response to an operator questionnaire. Since rod movement is accomplished by HS-1219, HS-1222, and HS-1223 and final pulls are limited to 2 inches, the safest mode of operation is spring return to 0FF. This necessitates holding controls for long periods of time, and is deemed to be desireat e to ensure positive control action.

SUMMARY
OF THE CONTROL ROOM IMPROVEMENT DESIGN PROCESS AS APPLICABLE TO THE REMOTE, I-06J AND I-15 ANNUNCIATOR UNIT INSTALLATIONS j
9 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 weie 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 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 i classifications of problems. This approach is first, one of determining functional groupings, followed by demarcating,
, hierarchial 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 in grouping, deleting and adding alarms. 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 i _ _ _ . - , , - - . - - _ . . _ . - . _ _ _ , _ _ _ _ -_.-_.._. . _ . , . _ . _ = , - ___ . . . - . , - - , _
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-(CNs) numbers were assigned to each effort identified above.
IMPROVEMENT PROCESS METHODOLOGY
~The Improvement Process for the annunciator system 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 ssigned the responsibility of evaluating the annunciator system. Since this individual had not participated in previous efforts, an educational process was initiated to acquire a thorough understanding of the annunciator system and each alarm. System descriptions, Piping & Instrument diagrams, electrical drawings, operating procedures and 0 & M manuals An operational were studied to gain this thorough understanding.
analysis was conducted for the system. (This in-depth analysis was in addition to that completed for the CRDR and planning purposes.) This Operational Analysis ;rovided additional basis for determining any changes to the annunciator control switches. Operating and training personnel are interviewed to solicit operational philosophies for the annunciator system. The Operational value and function of each alarm was addressed. Informational requirements are again discussed. (This informational requirements effort- is in addition to that conducted for Emergency Operating Procedures task analysis). All HEDs applicable to the annunciator system are reviewed and the tentative fix evaluated for its corrective value within the integrated approach. HEDs written against the alarms and control switches recorded by the Emergency Operating Procedure task analysis "Information and Control Requirements" effort, are reviewed with
-g.
o
-- O' particular attention to any potential safety considerations. Any previously -prepared investigative information was studied. All factors were evaluated in considering any changes to the system.
SPECIFIC - The Remote, I-06J and I-15 Annunciator Unit Installations
- (Change Notice (CN)-1924 preparation package.)
Research - CN-1924 was not generated as a direct result of an HE0; however, this CN is an important part of the integrated redesign of the- control room annunciator system. Presently the annunciator system for the Fort St. Vrain control room is nearly 100% utilized - very few spare annunciator windows are available. With this constraint on the annunciator system, the integrated redesign (i.e., functional grouping, adding new alarms, splitting out existing alarms, etc.) is difficult to achieve. The Control Room Design Improvement Group, realizing this constraint, investigated methods for increasing the number of spare alarm windows available in the
-control room. This investigation resulted in three proposed solutions to this problem:
- 1) A small number of alarms could be deleted.
- 2) Certain groups of alarms, those for which no corrective action can be initiated within the control room and those which require operator dispatch for remote corrective action, could be relocated out of the control room to remote equipment panels functionally grouped with their associated controls. A general dispatch alarm in the control room would direct an operator to the panel.
- 3) Install two new alarm panels in the control room.
Design ~ - A design was adopted that incorporated the proposals of the improvement group. A small number of alarms will be deleted by CN-1924:
- 1) FAL-2517 - N: Recondenser 1A malfunction trip
- 2) FAL-2518 - N Recondenser 18 malfunction trip
- 3) FAL-2527 - N Recondenser 1C malfunction trip Five remote annunciator units will be installed in the following plant locations:
- 1) I-9322
- 2) I-2301
- 3) Boiler Feed Pump.A
- 4) Boiler Feed Pump C
- 5) Refueling Deck (Fuel Storage Well Alarms) 3_
f
, - - __ . . , - _ - - ---_-v - - - -
When an alarm exists at the remote annunciator unit, a general dispatch alarm will sound in the control room directing an operator to the remote panel in order to learn the exact nature of the alarm and to initiate corrective action. Two new annunciator panels will be installed in the control room. One panel will be mounted on I-06 section A for the Hydraulic System. One panel will be mounted on I-15 for the HVAC System. A new annunciator. control station will be installed on panel I-15.

SUMMARY
OF THE CONTROL ROOM IMPROVEMENT j DESIGN PROCESS
- AS APPLICABLE TO I-09 RECORDER MOVE
e FOREWORD - NUREG-0737 Supplement 1, Section 5.lb requires that a
. Control Room Design Review (CROR) 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 reouired 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 CROR and the follow-on improvement program was directed toward the improved handling of emergencies and not specifically toward improved production. Pubite 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 classifications of problems. This approach is first, one of determining functional groupings, followed by demarcating, hierarchfal 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 cach control panel were color coded to show applicable HEOs 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 in grouping, deleting and adding alarms.
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 re'erence 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
-t.
s 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 utili:ed to determine the scope of each change package (change notice).
- Change Notice (CN) numbers were assigned to each effort identified above.
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 is assigned the responsibility of evaluating a particular board. Since this individual may not have participated in previous efforts, an educational process is initiated to acquire a thorough understanding of each system, subsystem and conpanent represented on the assigned control board. System descriptions, Piping & Instrument diagrams, electrical drawings, operating procedures are studied to gain this thorough understanding of each system and component function. An operational analysis is conducted for each system and component on a particular control board. (This in-depth analysis is in addition to that completed for the CRDR and planning ourposes.) This Operational Analysis provides additional basis for determining any changes to functional groupings. Operating and training personnel are interviewed to solicit operational philosophies. The Operational value and function of each control and indication is addressed. Informational requirements are again discussed. (This informational requirements effort is in addition to that conducted for Emergency Operating Procedures task analysis). All HEDs applicable to a particular control board are reviewed and the tentative fix evaluated for its corrective value within the integrated approach. HEDs written against instruments and controls recorded by the Emergency Operating Procedure task analysis "Information and Control Requirements" effort, are reviewed with particular attention to any potential safety considerations. Any previously prepared investigative information is studied. All factors are evaluatad in ccrisicering any changes to the control board. SPECIFIC - I-09 Recorder Move Synopsis - (Change Notice (CN)-lS78 preparation package.) Research - In an effort to generate more room on the main control boards to facilitate the rearrangement of controls and indicators, various recorders are to be moved from the main control boards to tne I-09 panel or local to the location of operator action. The recorder display survey was reviewed to determine which recorders were not required for plant operation and which recorders provided pertinent information that could be presented to the operator in a more direct and readily useable manner.
- Af ter the records to be relocated were identified, all HEDs associated with these were reviewed to determine problems with '
labeling, scaling, grouping, and useability. (See Attachment A) , Conceptual Design - The initial conception was to move the recorders not required for plant operation and those being replaced with another means of display out of the control room. Other selected recorders, which were determined to be necessary in the control room, but were not required in making control manipulations or system adjustments were to be moved to I-09. This idea was presented to several operators and trainers for comment. It was concluded that those recorders listed as not necessary for plant operation do provide valuable trend information and should be left in the control room. As a result of this survey, it was decided to place this group of recorders on I-09. These recorders were functionally grouped and labeled per the applicable Design Ofrectives. The final layout is included in Attachment B. i The following Design Directives apply to the I-09 Recorder Moves.

" DESIGN DIRECTIVE FOR THE SELECTION OF RECORDERS"
'. 00-RSN-1 DRAFT.
DESIGN DIRECTIVE FOR THE SELECTION OF RECORDERS FOREWORD: The purpose of recorders is to display and provide a permanent graphic record of relative or absolute values representing a system or process parameter. Recorders are a vital link in the operators interface with the control loop. The effectiveness of this interface depends on what information and how that information is presented. The use to which the operator will put the information presented, should serve to influence the level of information, as well as the manner in which that information is presented. This Design Directive will provide guidance in selecting recorders for use in the Fort St. Vrain Control Room. SELECTION CONSIDERATION s I. RECORDER USE A. Generally, recorders are used for data acquisition and . dispity in one of the following ways.
- 1. For quantitative reading (and recording) of an exact numerical value: reading time from a clock, reading pressure from a gauge, or electrical potential from a voltmeter.
- 2. For qualitative reading (and recording): this means judging the approximate value, trend, rate of change, or direction of deviation from a desired value. It differs from quantitative reading in that the operator does not read an exact numerical value. Examples include noting that a ship has veered to the right of a desired course, or that steam temperature is rising.
- 3. Data logging: the collection and storage of data including the means to transfer that data to other data handling or processing equipment. This particular function is primarily for analytical purposes and is not generally for immediate operational use.
B. Recorders that are to be used for quantitative readings shall have sufficent range and scale resolution to enable the operator to make a rapid and accurate determination of the displayed value. j
DD-RSN-1 Issue A Page 2 of 5 II. RECORDER TYPES There are many variations of several basic types of recorders, however only those acceptable for Fort St. Vrain use are listed. A. Multipoint recorders have a single processing and printing mechanism which alternately scans a large number of inputs. B. Dedicated Channel recorders have separate signal conditioning and pens or stylus for each input. This type of recorder is usually limited to three or four channels. III. SELECTION OF RECORDER TYPE While certain technical requirements may suggest the type of recorder, panel layout, convention and operator expectations are important factors to be considered. It is not the intent of this directive to preclude the use of particular types of recorders, but rather encourage the use of those types that meet the majority of operational, maintenance, human factors and data logging functions. A. SELECTION CONSIDERATIONS
- 1. Operational interface - recorders selected for control room use shall be so designed and structured to facilitate operator control and ease of function selection. The following items are to be considered as minimum requirements.
- a. Only operator controls are to be visible on the recorder panel.
- b. All operator used controls shall be on the recorder front panel.
- c. Controls (buttons-switches) shall meet the requirements of 00-SWI-1 (Switch Selection).
- d. All control labels and legends shall meet the requirements of 00-LAB-1 (Labeling) and 00-AAS-1 (Abbreviations, Symbols and Acronym Selection)
- e. Operator controls shall include " point selection",
" chart speed selection", " paper advance" and " fast enable". (fast enable will allow speed change from a remote source) i
00-RSN-1 Issue A
'- Page 3 of 5
- f. Paper Change operations shall be accomplished without the use of special tools or equipment.
Any required instructions shall be posted or otherwise shown on the recorder structure.
- g. Data printed shall be immediately visible to the user without the use of the paper advance feature.
- h. Print size and Numerical displays (if applicable) shall be in accordance with DD-AIS-1 (Selection of Analog displays.)
- 1. Contrast - Character-to background contrast ratio shall between 15:1 and 20:1.
J. Bezel Markings - Recorder front or Bezel areas shall be free of logos, range markings, and print td material not directly related to the recorder function, parameter or value displayed.
- k. The recorder scale range shall be consistent with the parameter range being recorded.
- 1. The number of points assigned to a recorder for quantitative reading shall be limited to ensure readibility of each point.
- 2. FUNCTIONAL CONSIDERATIONS
- a. The recorder shall be equipped with an EIA-STD-RS-232C port.
- b. The recorder shall be equipped to perform the following functions:
Common time update including t.'.e year, month, day, hour, minute and second. (hour designations shall be based on the 24 hour clock) Data transmission at a rate of at least 1200 BAUD and in an eight bit with or without parity configuration. Remote programming (down load from a P.C.)
- c. The recorder shall have a back-up power supply or include another means of retaining the operating program in the event of primary power failure.

SUMMARY
OF THE CONTROL ROOM IMPROVEMENT , DESIGN PROCESS 4 AS APPLICABLE TO THE
- HYDRAULIC SYSTEM CONTROL / INDICATION
- FUNCTIONAL GROUPING ON I-06A 1
I e
FOREWORD - NUREG-0737 Supplement 1, Section 5.lb requires that a Control Room Design Revicw (CRDR) be conducted to identify huran engine: ring 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 Fcrt 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 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, hierarchial 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 in grouping, deleting and adding alarms.
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 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 i
. l 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 were assigned to each effort identified above.
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 is assigned the responsibility of evaluating a particular board. Since this individual may not have participated in previous efforts, an educational process is initiated to acquire a thorough understanding of each system, subsystem and. component represented on the assigned control board. System descriptions, Piping & Instrument diagrams, electrical drawings, operating procedures are studied to gain this thorough understanding of each system and component function. An operational analysis is conducted for each system and component on a particular control board. (This in-depth analysis is in addition to that completed for the CRDR and planning purposes.) This Operational Analysis provides additional basis fer determining any changes to functional groupings., Operating and training personnel are interviewed to solicit operational philosophies. The Operational value and funct 1 of each control and indication is addressed. Informational requirements are again discussed. (This informational requirements effort is in addition to that conducted for Emergency Operating Procedures task analysis). All HEDs applicable to a particular control board are reviewed and the tentative fix evaluated for its corrective value within the integrated approach. HEDs written against instruments and controls recorded by the Emergency Operating Procedure task analysis "Information and Control Requirements" effort, are reviewed with particular attention to any potential safety considerations. Any previously prepared investigative information is studied. All factors are evaluated in considering any changes to the control board. SPECIFIC - Hydraulic System Controls / Indicator Functional Grouping - (Change Notice (CN)-1885 preparation package.) Research - During this phase the control and indications related to the Hydraulic System were studied using the applicable system abstracts, System Operating Procedures, and system drawings. In addition, both the Technical Sgtcifications and Final Safety Analysis Report were reviewed to determine the operational (process) control limits and safety interactive controls ano systems. Other research included discussions with operators, trainers, and engineering support personnel. This interaction with other sectors was continued throughout the research and design phases. A review of all related HEDs was performed and design problems reviewed. (See Attachment A). Review of the HEDs and a physical study of the panel verified that there were problems in grouping, labeling, meter scaling, switch and light conventions. The original board layout is included as Attachments B, 81, & B2. Conceptual Design - While the Hydraulic System is a support system for the secondary coolant system, space availability on I-05 control board prevented locating all related Hydraulic controls and indications in loop related arrangements at a fuxtionally preferred location. For this reason it was deemed advantageous to provide a c'edicated space adjacent to I-05. After the existing design was reviewed, preliminary redesign proposals were made using elevation drawings, modified to show proposed changes. As each proposal was studied, its operational relationships were evaluated to make certain that the arrangement provided the best man-machine interface. This design provided for loop related grouping of controls and displays on a section of the I-06A control panel. In this process, several iterations of a layout were evaluated. 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 design and operational parameters were met. Sample copies of the Interview records are included as Attachment C. These interviews were conducted in the following manner:
- The final iteration of a proposed layout was presented to an operator.
* .he operator was asked to evaluate the proposed layout. Particular attention was given to the functional grouping and the operational relationships of the controls and indications.
1
i
- Information and control needs were reviewed.
The operator was asked to evaluate the proposed labeling and scaling presentations to veri fy that the required information was presented in a clear, concise and readily useable format. This " table top" analysis was conducted with various operators, shift supervisors and trainers. (See Sample Interview records, Attachment C). This verification effort. resulted im operators expressing concern over labeling of PI-9105, PI-91141, PI-9106, and PI-91142 as " system emergency....", the order of pump switch arrangements, the arrangement of the digital indicators and selector switches, and the need for an operator aid legend plate listing hydraulic actuated valves. Further examination resulted in making the suggested changes. This finalized layout is included as Attachment D. A major concern was expressed concerning division of responsibility. The present division of responsibility occurs at the I-05/I-06 boundary. System 91 controls are presently located on both sides of the line. This division of responsibility is an administrative responsibility and will undoubtedly be commensurate with the recommendation that the hydraulic power system functional group be included with I-05 responsibilities. A summary of changes for the hydraulic system control and indicator layout is presented by Attachment E. The final step in this conceptual design phase was to determine the final text content for functional labels. Prior operator interviews and operational analysis efforts provided the basis for these determinations. See Attachment F for Functional Label legends. The following Design Directives apply to the Hydraulic System Controls / Indicator functional grouping effort.

Date: 13 November 1985 Ir.vestigative Informational Record - Ans.,a.3 :: Cussti:ns Respondent: John Maynard, Senior Licensed Operator Question 1: Yes. Question 2: "The layout bothers me the most."
"The alarms are scattered."
Question 3a: Effect responsibility. The division line is at I-05/I-06.
"No difficulties. I preferen:ed it there." (Interviewer's comment: The operator was referring to tne proposed location of the hydraulic controls.)
3b: PI-9105, 9106, 91141, and PI-91142 should not be labeled - emergency. (Interviewer's comment: Noted and changed). Question 4: " Lot easier."
" Good location" Page 2 of 5
Date: 14 November 1985 Investigative Informational Record - Answers to Questions Respondent: Willard Ashmore, Trainer, (former licensed operator) Question 1: 'Yes. Question 2: Spread all over. Not organized. Question 3a: Good location for hydraulic controls. 3b: Handswitch positions should correlate with the pump's actual field location. (Interviewer's comment: Sequence of opera-tion and consistency of functional grouning determines hand-switch position. Field location is of minimal concern.) I don't like the meter and selector switch layout. - (Interviewer's comment: noted and changed) Question 4: Grouping of hydraulic controls on I-06A shifts responsibility for the hydraulic controls. (Interviewer's comment: _ The
- I-05/I-06 dividing line is also the division line between j operator responsibility. Presently the hydraulic alarms and controls are split between I-05 and I-06. The alarms i
are to be addressed in a separate change.) This move will define responsibility. t i 1 Page 3 of 5
Date: 14 November 1985 Investigative Informational Rccord - Answers to Questions Respondent: Steve Shafer, Shift Supervisor (Senior Licensed Operator) Question 1: Yes. Question 2: '"The loop split is 0.K."
" Labeling is inadequate."
" Selector Switch selector and alarm could be better."
Question 3a: I like the idea of putting it all together, like the location on I-06A. 3b: Approved of digital indications. Better indication for the - tight range of the pressure limit. Accumulators have a narrow operating band. HS-91151 and HS-91152 change to SMB type switches is good. Would like a legend plate (operator aid) identifying valves being operated. Question 4: May not make that much difference. Better because of the functional group. Improves I-05 by removing excess controls. 3 i l l Page 4 of 5 l l L -
i CONCLUSIONS: A review of the investigative interviews indicates a general acceptance of the proposed hydraulic system controls revision. Several minor changes were suggested by respondents during the interviews. These were' evaluated and acted on if there was merit in the suggestion. Iomparing the enlarged functional group layout sketch used for the interviews with' final layout shown in Attachment E, these minor changes are obvious: i) changed the pump switch order
- 11) centerd the hydraulic oil pressure indicator iii) added operator aid legend plate.

SUMMARY
OF THE CONTROL ROOM IMPROVEMENT DESIGN PROCESS AS APPLICABLE TO CONTROL ROOM FURNSHINGS & ARRANGEMENT 9
~
t 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 operating error and the potential effect of any error. (Certain die-repa,cies are known to have caused errors). An improvement program has been selected which meets the regulatory requirements and pruposes 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 'nd the handling of emergencies.
BACKGROUND - There were nine (9) Human Engineering discrepancies initiated against the control room proper. Of these nine total, five (5) cited lighting or lighting related problems which will be addressed by a separate activity (CN-1898). One cites nomograms and placards which will also be addressed by a separate activity. The chree remaining HEDs relate to housekeeping, noise, and one potential safety concern. This potential safety concern will be addressed by the I-06B and I-09 control board arrangement changes. The two HEDs to be addressed by this change are Housekeeping and Noise. Public Service Company has initiated an integrated improvement program based on functionality rather than particular classifications of problems. While there are methods to effectively address the housekeeping and noise problems separately, the concept of addressing these problem areas in an overall control room furnishings and arrangement package appeared to offer i= proved operations, by reducing operator fatigue through an improved operating environment. Revised drawings were prepared to show the proposed arrangements. Certain of these drawings were color coded to aid in evaluating proposed arrangements. Finalized drawings are being utilized to determine the scope of.each change package (change notice). Change Notice (CN-1899) number is assigned to the Control Room Furnishings and Arrangement Changes. , IMPROVEMENT PROCESS METHODOLOGY The Control Room Environment Improvement Process started with the selection of an outside design consultant with experience in designing control room furnishings and recommending arrangements. This designer was assigned the responsibility of evaluating the control room environment in general and spscifically addressing the applicable HEDs. Operating practices were studied to gain an understanding of the plant control duties, traffic, and other control room responsibilities.
. -. _ - - _ . _ - _ =- _ . _.
Operating and training personnel were interviewed to solicit operational philosophies. The operational value and function of each item of furniture was addressed. Procedure and reference requirements were reviewed. All HEDs applicable to the control board room proper were reviewed and tentative fixes proposed. All known factors were evaluated in considering any changes to the control room. SPECIFIC - Control Room Furnishings and Arrangment Synopsis - (Change Notice (CN)-1899 preparation package.) HED-0551 cited Alarm Audible Levels. This HED suggests the background noise within the control room has created a necessity to
'. increase the sound levels of audible alarms; however, even now the db level difference between alarms and background noise is below minimum standards. The chillers and reciprocating pumps located above the control room are the major cause of the background noise.
The vibration isolators (sound mounts) for this equipment were inspected and found to be in satisfactory condition. While isolation of ducts and piping from the building structure may reduce the noise level, sound absorption within the control room appears to be the more viable solution. Sound absorption treatment in the control room itself involves the floor, walls, and ceiling. A floor carpet has been explored which meets the required fire retardant properties (ASTM-E84, 25 or less) for nuclear power plant control rooms. The product is referred to us as Bigelow Grograin III. The carpet can be purchased in carpet tiles which will make replacement in high wear areas convenient and less costly. In addition to its obvious sound absorbing properties, the introduction of carpet will create a means for color coding the vital areas in the control room, reduce operator leg fatigue, and add a professional orderliness to the room as needed and indicated in HED-0645.
. For sound absorption on the walls, a composite of fiberglass semi-rigid 700 Series Insulation by. Owens-Corning, with a plastic extrusion frame covered in FR701 Panel Fabric by Guilford, Ind.,
meets the fire retardant requirements. The acoustical properties are
- NRC (Noise Reduction Coefficent)
- .90 and NIC (Noise Isolation Class)
- 21. Custom panels will be fabricated to deal with the irregular items required on the walls of the control room. Again, HED-0645 would be addressed by using this composite.
The ceiling treatment is being approached by the installation of an acoustical ceiling tile of about an NRC range of .70 .80. This necessitates installation of Halon discharge at the drop ceiling level, the ceiling tiles would serve many functions beyond sound absorption, including light reflectance which is being addressed by separate activity.
Housekeeping HED-0656 cites the general arrangement and storage i problems which exist along with indicating a general need for a professional, uncluttered appearance within the control room. In addition to the professional appearance aided by floor, wall, and , ceiling modifications discussed so far, the intent is to use a consistent style in cabinetry and furniture. All items for this purpose are being selected for ease of maintenance and longevity or durability. Where possible, a bumper rail is to be installed along the walls and around cabinets as physical protection. All paint to be used on workstations and painted surfaces is specified as a catalytic paint which is extremely scratch resistant. Personal storage is being provided for all assigned control room personnel by the installation of lockers in the adjacent room east of the Main Control Room. In addition, lateral files, large and small parts storage' cabinets, hard hat, lunch pail, and coat racks are provided for by the new furniture arrangement. These additions are intended to reduce clutter and create a more professional environment. A lunch counter is to be added and the kitchen reorganized. Besides housekeeping concerns, HED-0656 cites disorganization within the control room. Further investigation identified and clarified this generalization. The specific problems can be summarized as poor document storage and workstation locations, sightline obstructions, and excessive non-control room personnel traffic. The new design and arrangement of the workstation allows for viewing the control boards while seated and concurrently operating any of the CRTs without having the operator turn his back on the control boards. Operator-to-Operator visual contact will be possible standing or sitting from any point within the main controls area. Dedicated space for P& ids, and operating / emergency procedures will be provided with designated lay down space. The third position operator workstation is situated on a raised floor near the southeast control room entrance. This raised area provides a clearance point for non-control room personnel, and provides visual advantage to the third cperating position. A new log desk / station is designed to further reduce congestion. j See Attachment C for the proposed control room arrangement.

I Summary of Sound Level Survey Conducted for the FSV - CRDR , A sound level survey was conducted on 11 January,1984 between the hours of 0900 and 1100 AM. Reactor Power was 68% (secondary heat balance). Alarm activity was minimal. Paging and conversational activities were normal.
'It was noted that the Alarm Horn level was reduced slightly, r common and randomly occurring situation.
Background sound pressure levels for A, B, and C weighted readings were recorded for specific locations (both operator and non-operating positions) ou Form 344-24-4238, " Control Room Plan View". I-70 Annunciator system audiable alarm levels were recorded for operator positions. These alarm levels were not taken for "B" weighted values. Sursary - Average Background - SPL, "A" weighted = 62.9 db Average level with Alarm - SPL, "A" weighted = 69.0 db Average Eackground - SPL, "B" weighted = 68.4 db Average Background - SPL, "C" weighted = 73.5 db Average level with Alarm - SPL, "C" weighted = 75.8 db Average level with Scram Horn at operators desks, "C" weighted = 83 db Average Page level above Background, "A" weighted = 2 to 10 db Average Conversational level above Background, "A" weighted - = 2 to 6 db Shif t Supervisor SPL, "A" weighted = 64 db Shif t Supervisor SPL, "B" weighted = 72 db Shif t Supervisor SPL, "C" weighted = 76 db Documentation - Survey sheets CRS-13 & 14 3 Control Room Plan Views, each marked for A, B, or C weighted Sound pressure levels

SUMMARY
OF THE CONTROL ROOM IMPROVEMENT DESIGN PROCESS AS APPLICABLE TO CONTROL ROOM LIGHTING 4
+
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 operating error and the potential effect of any errcr. (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 - Three HEDs were generated as a result of lighting level surveys. (See example included as Attachment A). - Normal Lighting Levels - HED 0480 cited light levels below 50 f.c. (48 f.c. measured) near I-9310 and I-9315 panels. The reason for ' this below minimum subsequently replaced. level was defective bulbs. These bulbs were Emergency Lighting Levels - HED 0482 and 0486. All control room i locations have insufficient (0-4 f.c.) illumination which results in some difficulty identifying controls, or obtaining required readings. This reduced light level also reduces color discrimination. The present emergency system consists of 12-100W incandescent fixtures located above the luminous ceiling louvre. This system creates a different visual environment during an emergency situation primarily due to light level and light color (2800 K approximately). The exi_ sting illumination deficiencies can be summarized as glare / fatigue during normal conditions and celor/ pattern problems during emergency conditions. These problems are not generated by the same lighting system. The lighting survey done on 10/17/85 identified clearly the deficiencies in the " emergency" mode lighting system. Most of the measurements were in the range of 0-4 f.c. with great number of locations with "0" or unreadable meter level. The Illuminating Engineering Society of North Amef pa significantly revised the recommended illuminance levels in 1981. The new procedure recognized that previous systems did not produce good lighting with high visual clarity. The new levels suggest a range, 20-50 foot candles horizontal for power plant cont + al rooms. This is
=_ - -- . _ - . .
1 expressed as Lighting Category "D". Unfortunately, meeting this criteria even on the high range, (50 f.c.) does not insure a " glare-free" (on the instrument faces) installation. Glare is an undersirable reflection which challenges visual acuity. Any direct downlight source will generate " glare" on shiny instrument faces and dials. HED 0485 cites Glare on Indicators. The overwhelming majority of vertical indicators have glare, requiring the operators to shift relative positions to eliminate glare at different scale values. The existing lighting system consists of exposed fluorescent fixtures above a white louvre ceiling 12" above the top of control consoles. The lamps are arranged in single lamp reflector strips (225-4' units) located above the louvre. The glare is a direct reflection of the lamp image or the louvre blades. The lighting survey executed on 10/18/83 graphically indicated light meter positions on the vertical plan of the board, which complied with the quoted illumination level of 50 f.c. (in both horizontal and vertical planes). IMPROVEMENT PROCESS METHODOLOGY The lighting Improvement Process started with the selection of an outside design consultant to address the control room furnishings and arrangement improvement as well as the lighting problems. This designer was assigned the responsibility of determining and evaluating the improvement options. Since this individual did not participate in previous efforts, a site visit was initiated to acquire a thorough understanding of the control room arrangement and existing lighting systems. Operating and training personnel were interviewed to rolicit operational philosophies. The Operating environment was stu:Nd and the environmental considerations for each control room task were evaluated. Informational and reference material requirements were again reviewed. All HEDs applicable to the control room proper were reviewed and the tentative fix evaluated for its corrective value within the integrated approach. SPECIFIC - Control Room Lighting Change Synposis - (Change Notice (CN)-1898 preparation package.) The selected design uses 68-4'-34 Watts-Ultralume 300 lamps and 8-13W recessed fluorescent fixtures over the work stations for normal lighting generating a connected load of 2416 Watts. This is an important reduction in connected load which will also affect the comfort level of the space since less heat will be radiated.
Presently 1/3 of the normal lighting in the control room is fed from an essential lighting cabinet with a connected load of 3775 watts. All the proposed normal lighting will be fed from this essential lighting cabinet i with a reduction of about 1300 watts. This proposed design was selected to produce comfortable, glare-free, high color rendering illumination, both during normal and emergency conditions. This proposed lighting system was designed to reduce reflected glare from instruments by reflecting the light from the ceiling, allowing this surface to become a large area luminous radiator. Also, since the emergency source is located along side of the normal source, light patterns and room orientation will be the same as during normal lighting operation. The lamp color family was selected for its known high color rendering index and high visual clarity and because its color temperature enhances the feeling of quiet and calm with lower fatigue. The designed emergency system generates 1/2 of normal light level from the same location and in the same direction with the same lamp color. This will maintain all normal visual orientations, brightness ratios, and modeling while only reducing tne relative level to 1/3 of normal. The selected design uses 34-4'-34 watts-ultrlume 300 lamps and 8-13W recessed fluorescent fixtures over the work stations for emergency lighting. The system also takes into consideration the limited amount of emergency energy available and maintains the connected load (1,260 Watts) close to the present system load of 1200 Watts. .The ballasts are operable from the U.P.S. system and are of the instant-start type. 4
