FOREWORD -
NUREG-0737 Supplement 1, Section 5.Ib 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 discrepancies are known to have caused errors). An improvement j 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.
- An Elevation drawing of each panel was color coded or marked to show all applicable HEDs as relabeling, relocations, scaling, deletions, or equipment change-out. This scheme provided an overview of the problems documented on each control board or panel.
- All HEDs involving alarms were reviewed.
System function and operator responses were considered in grouping or deleting alarms.
- Operator interviews were conducted to determine their interpretations or actions to each component or mimic display on the panel.
- Controls and indications were arranged functionally. Associated alarm locations wers rechecked to verify that the more desirable locations were selected.
9
- A drawing was prepared to show the proposed arrangement.
= A Change Notice (CN) number was assigned to each effort identified above.
IMPROVEMENT PROCESS METHODOLOGY APPLICABLE TO I-7507X 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 I-7507X.
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, operating procedures are studied to gain this thorough understanding of the system and component functions. An operational analysis was conducted for the system and components. (This in-depth analysis is in addition to that completed for the CRDR and planning purposes.) This Operational Analysis provided additional basis for determining any changes to functional groupings.
Operating and training personnel were interviewed to solicit operational philosophies. The Operational value and function of each control and indication was addressed. Informational requirements were again discussed. (This informational requirements effort is in addition to that conducted for Emergency Operating Procedures task analysis). These interviews are documented and samples are being submitted as an attachment to this design package.
All HEDs (see Attachment A) applicable to the I-7507X panel were reviewed and the tentative fix evaluated for its corrective value within the integrated approach. Any previously prepared investigative information was studied. All factors were evaluated in considering any changes to I-7507X.
SPECIFIC -
I-7507X Redesign Synopsis - (Change Notice (CN)-1894 ~
preparation package.)
Research - During this phase, a study was conducted on the HVAC system as related to the I-7507X panel. This panel primarily provides indication and control of the three room control complex HVAC systems. In addition, I-7507X includes provision for the manual control of the Turbine Building Supply & Ventilation Dampers and the Access Control Bay Exhaust Fan for use during a fire. A system study was done using the related System Description, System Abstract, System Operating Procedure, Technical Specifications, and System Drawings.
Other research included discussions with operators, and engineering support personnel. This interaction with other sectors continued throughout the Research and Design phases.
o.
o 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 were evaluated to make certain that the arrangement provided the best man-machine interface.
This design provided for placement of controls and displays within the functional group.
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 iteration of a proposed layout was presented to an operator.
- The operator was asked to comment on the layout in relation to various tasks that he would perform.
- Information and control needs were reviewed.
The interview phase brought forth several concerns; some of which proved to be valid. As a direct result, the finalized proposed layout includes: lamp test buttor.s for damper position indicating lights, and status "Run" legend lights above fan symbols on the mimic layout.
Investigations failed to establish a need for filter high temperature
~
- alarms other than those which exist.
Operations personnel concurred that although there is a need for an hour meter to show control room HVAC filter use, it should not be located in the control room but rather local to the filter or on panel I-7501X.
During a " table top" discussion on the I-15 panel, it was decided that indicators TI-7553, MI-7554, TI-7555, PDI-7556, and TI-7557 l should be relocated to panel I-7507X for functional grouping.
Reevaluation of the HEDs indicates HED 0354 is no longer valid since it refers to the labeling of a fan symbol on the 480V switchgear room mimic. Since the 480V switchgear room mimic is being deleted, the
! l I
HED is no longer valid. HED 0461 refers to the labeling of an alarm for the Technical Support Center HVAC filter. This alarm will be relocated to the I-I5 Alarm panel.
The finalized proposed layout is included as Attachment D and a summary of proposed changes is included as 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 efforts provide the basis for these determinations.
See Attachment F for Sample Functional label legends.

CONTROL ROOM IMPROVEMENT DESIGN PROCESS AS APPLICABLE TO I-10 CONTROL BOARD
]
i .
'c 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 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 functior.ali ty 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 change-out. 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 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, and operating procedures are studied to gain this thorough understanding of each system. (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). Samples of these Investigative Informational Records are submitted as Attachment B to this design package.
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
_____--______________]
o 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 - I-10 (I-9310) Redesign Synopsis - (Change Notice (CN)-
1895 preparation package.)
The system review process for I-10 was like other segments of the control room redesign effort, approached in phases. The outstanding difference for this panel is that it mainly contains the electronics for the Plant Protection System (PPS) and is located on the back side of the main control boards. The function of this equipment is one of monitoring plant parameters and providing protective action when certain setpoints are exceeded. Personnel interface with this panel may be classified as follows:
- Operational use (normal and emergency)
- Surveillance (operating recording of data)
- Maintenance (repair and testing)
Of these three, only operational use during emergency operations requires timely operator recognition to assure resetting certain tripped bistables during core cooling restoration procedures.
Most of the HEDs initiated against this board were for control sizes, control physical configurations, meter scaling, labeling text, and label character sizes. Due to space limitations, it is not possible in most cases and not reasonable in others, to increase the size of labels and controls associated with the PPS system. The controls and indications utilized by the operators during emergency operations were identified and improvement options evaluated.
Miniature meters installed in the NIM bins of I-9310 are in fact primarily for surveillance and maintenance use. Critical parameter values displayed on the NIM bin _ miniature indicators are also displayed on the main control boards for operator use. (No additional changes are planned in response to those HEDs citing meter scale problems on I-9310.)
Research - During this phase, the systems represented by I-9310 were studied using the applicable System Descriptions, System Operating Procedures, Emergency Procedures, System Drawings, and the Control Room Design Review Task Analysis to determine the controls needed for emergency operation.
Other research included discussions with operators, trainers, and engineering support personnel. A review of all related HEDs was l
performed and each design problem was reviewed in order to find a solution within the space confines of the board (see Attachment A).
4 It was determined that the only controls utilized by the operator during an emergency situation are eight histable resets required for restoration of adequate core cooling. These resets are located on bins 402, 602, 1002, and 1202 position P1/2, and bins 404, 604, 1004, and 1204 position P5/6. Numerous other labeling improvements are feasible within the room constraints of this board. These improvements support routine operation and monitoring activities.
Conceptual Design - Detail drawings were made of the modules required during emergency operations. The original design did not provide for a reset button conforming to recommended sizes nor adequate labeling to enable timely operator identification. The proposed improvement will demarcate around the control, color patch and provide a " reset" label. Additionally, the module will be provided with adequate functional labeling. These " location-aids" are shown on Attachment C, Details 8 & C.
The XCR relay drivers are not required for operator use during an emergency situation, but are used as a diagnostic tool to determine the cause of a trip. The present instrument labeling under the module is confusing since the lights on the module for the XCRs are -
in a vertical array and the label is in a two-line configuration reading left to right. Operator aids are presently posted near the modules and provide a location key, function and reset information.
An attempt was made to label each XCR with the instrument number and function. Due to space constraints, letter sizes would be compromised to the degree of not being legible from the operating position for all operators. The cptimum solution was found to be that of labeling each set of indicating lights with instrument numbers (see Attachment C, Detail 'A), enlarging the operator aid, and possibly moving these operator aids to a more convenient location.
The present labeling on the nuclear instrumentation uses Roman numerals on the front of the I-03 section of the main control board and Arabic numerals on I-10. .
All nuclear instrumentation channels are to be labeled with Roman numerals for consistency, in accordance with industry convention. By increasing the size of the label under these bins to the maximum physical size allowed, the letter size may be increased to a size close to compliance with DD-LAB-1.
Other changes to the board are detailed in the individual HED dispositions on Attachment A and the summary of changes on Attachment D.
Reevaluation of HED-0589 and 059C resulted in the determination that no additional action was required.
- HED-0589 cites the number of graduation marks on an indicating meter between numerals.
These meters are- used for calibration purposes. Duplicate indication is available 1
to the operator on the main control panel, I-03.
- HED-0590 was initiated in response to a standard checklist item. It is not applicable to the log scale meters cites.
The final step in this conceptual design phase was to determine the final text content for functional labels (see Attachment E for an example of the Label List.)

r 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 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 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 assigned the responsibility of evaluating the ar.nunciator 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 , were studied to gain this thorough understanding. An operational 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 provided additional basis for determining any changes to the annunciator control switches. Operating and training personnel were interviewed to solicit operational philosophies for the annunciator system. The Operational value and function of each alarm was addressed. Informational requirements were 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 were reviewed and the tentative fix evaluated for its corrective value within the integrated approach. HEDs written against the alarms and control switches by the Emergency Operating Procedure task analysis "Information and Control Requirements" effort, were reviewed with
-g-
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 - Miscellaneous Alarm Modifications Synopsis - (Change Notice (CN)-1925 preparation package.) Research - During this phase, the fire alarms and the annunciator system were studied as listed below:
- 1. Abstracts of the fire protection / detection system were reviewed.
- 2. The control room was surveyed to obtain a complete list of audio alarm horns, bells, f etc.
- 3. Applicable HEDs were reviewed.
- 4. Operators and trainers were interviewed to determine the need/ response to special audio i alarms.
- 5. Operators and trainers were interviewed to determine operational needs of the fire i protection / detection system.
1 Conceptual Design - After the original design and all relevant I documents were reviewed, a proposed design was developed which addressed _the HEOs and met the operational requirements. This ! approach is one of functional grouping HVAC and fire alarms on the associated control panel or board according to function, separating the general alarm audible alert according to control board-responsibility assignments, and providing a visual indication of unacknowledged alarms. This proposed design provides for the following: i
- 1. The general annunciator horn will be segmented
.into two separately distinguishable horns.
One horn will provide an audible alert for the I-01, I-02, I-03, I-05 and I-13 alarms. The other horn will provide an alert for the I-06 and I-15 alarms. This segmentation of the annunciator horn closely corresponds with the control room operator division of responsibility.
- 2. New general annunciator horns will be installed that are adjustable for waveform, tone and amplitude. Waveform and tone will be adjusted to assure that the horns are
' separately distinguishable. Amplitude will be adjusted adequately above normal background
m a'
. . . s noise levels. Adjustments will not be i available to the operators.
1
'3 . Red indicating lights will be installed above all the I-01, I-02, I-03, I-05, I-06, I-13 and I-15 alarm panels. The red light control
, circuit will be modified so that the lights will illuminate above the panel upon actuation of an alarm. The red light will stay
' illuminated until the.' respective alarm control station "ACKNOWLEDG:" botton has been pushed. l
,s
- 4. The annunciator' control circuit will be
. modified to permit the operator to ' silence u either general ann'Unciator horn from tha I-01, I-02, I-03, I-05, I-06 Section A, I-06 Section
+ B, I-13, or I-15 control stations.
- 5. Modify the control circuitry on the I-010 and I-01E Betalert-10 annunciator. The " RESET" and " TEST" switches will be removed from the face of these units. The test feature of the Betalert units will be controlled' from the I-02tannunciator control station..
- 6. Relabel the vari'ous fire zone windows on XC-45153P to provide' explicit operator information.
- 7. Functionally relocate related instrumentation (indicating lightsf and ' alarms) to the XC-45153P panel.
- 8. Modi fy or, replace existing XC-45153P alarm

SUMMARY
OF . ACTUAL CHANGES TO CN-1925 The following is a summary of the CN-1925 changes:
- 1. The control room annunciator into two horns, each dedicated horq',,will be segmented to specific control panels. (These horns will be adjusted for waveform, tone and amplitude.)
- 2. Red indicating lights will be installed above all alarm panels that when illuminated, indicate an unacknowledged alarm condition on the panel.
- 3. The annunciator controls will be modified so that the horns may be silenced from any alarm control station.
- 4. Control of the I-01D and I-01E annunciator units will' be simplified by controlling the test function from the I-02 control station.
- 5. Panel XC-45153P will be relabeled to clarify instrument functions.
- 6. Functionally related instrumentation will be relocated to XC-45153P panel.
- 7. XC-45153P controls will be modified or replaced to conform to human engineering requirements.
