Discussion The Virginia Electric and Power Company (VEPCO) submitted a Detailed Control
~
Room Design Review (OCROR) Program Plan for its Surry and North Anna Power We have Stations to the Nuclear Regulatory Commission on March 1,1984 reviewed the plan against the requirements of Supplement 1 to NUREG-0737.
The Program Plan states, on page 1-3, that it is intended that the plan be a baseline for any audit of VEPCO's CROR. The licensee should be advised that the NRC will use the reouirements of Supplement I to NUREG-0737 and the guide-lines of NUREG-0700 and NUREG-0801 in their audit.
A human factors evaluation of the design of the remote shutdown capability provided to meet 10 CFR Part 50, Aopendix A GOC-19, and 10 CFR Part 50, Appendix R is not specifically identified as a requirement in Supplement I to In the interim, NUREG-0737.
NRC staff review of this issue is not complete.
we recommend that the scope of the DCROR include a human f actors evaluation of To the extent practicable, the design of the remote shutdown capability.
without delaying completion of the DCROR, it should also address any control room modificatons and additions (such as controls and displays for inadeauate 0 1 1
core cooling and reactor system vents) made or planned as a result of other post-TMI actions and the lessons learned from operating reactor events s Generic implications of the Salem ATWS events are discussed Salem ATWS events.
in NUREG-1000 and required actions are described in Secton 1.2, " Post-Trip Review - Data and Information Capability," of the enclosure to Generic Letter I
83-28.
The following comments apply to specific elements of the Surry/ North Anna .
DCRDR Program Plan.
Qualifications and Structure of the DCRDR Team Supplement I to NUREG-0737 recuires that the licensee establish a cualifie multidisciplinary review team. The VEPC0 DCRDR team will consist of a 10-member core review team, which will be supplemented by up to 17 add The availability of these members supporting members on an as-recuired basis.

the c5re team will be members of the Human Engineering Discrepancy Asse The HEDAT will review and assess all HED reports, develop Team (NEDAT). fit recommended resolutions, and establish preliminary schedules for all back activities.
Figure 2.2 of the licensee's Program Plan shows that the primary man structure of the team is comprised of the HEDAT members, and that huma project management and expertise is provided by a consultant, the Esse
' Corporation.
The VEPCO Lead Discipline Engineer (LDE) has overall responsibility for following the planned schedule, reviewing progress, resolving problems, He chairing project meetings, and reporting project status to his managemen EDAT review will also act as HEDAT team leader and ensure strict adherenc procedures.
4 d
Liaison with corporate management will be provided by the Nuclear Operations Department (N00) Corporate Project Coordinator, who will also act with other coordinators in staff capacity to the LDE.
The Station Coordinators for Surry and North Anna are responsible for determining station facility, personnel availability and activity coordination as appropriate, and for providing operational expertise.
The two lead Essex human factors (HF) specialists are responsible to the LDE for, and will ensure the technical quality of, human factors work and the availability of other appropriate HF specialists as appropriate throughout the project. They will coordinate all HF activities and will contribute to the HEDAT functions. The HF specialists are committed to collect, reduce, and The major DCROR analyze data, and to locate, analyze, and resolve HEDs.
planned activities and approval cycles are illustrated in Figure 2.4 of the plan. Figure 2.3 of the plan describes in matrix format the 15 OCROR task assigments of the support staff personnel and each category of team member, t
oith coded identification of prima ~ry responsibility, support responsibili y, and approval authority. .
Appendix A of the Program Plan contains the resumes of HED assessment team members.
We conclude that the VEPCO management and staffing effort has been adequately
. planned, and that the DCROR team will have access to a suitable diversity of expertise. To enhance the qualifications and structure of the OCRDR team, we recommend that a formal program of HF orientation and training for non-HF specialists be instituted and. executed to provide a common basis of under-standing for review team members.
B'ased on our review of the qualifications, organization, and management structure of the Surry/ North Anna review team, it is expected that the licensee will satisfy the reauirement of Supplement I to NUREG-0737 to establish a qualified multidisciplinary review team to conduct a DCROR.

The SFTA method described in the plan (4.4.2) states that emergency event sequ'ences which challenge safety-related functions will be considered from the following list of scenarios: ,
o Small loss of coolant accident o Inadequate core cooling o Anticipated transient without reactor trip following a loss of off-site power o
Multiple failure of tubes in a steam generator and tube ruptures in more than one steam generater.

r-The NRC memorandum of April 5,1984, from H. Brent Clayton to Dennis L.
Ziemann, " Meeting Summary--Task Analysis Reouirements of Supplement I t meeting with Westinghouse Owner's Group (WOG)
NUREG-0737, March 29, 1984 Procedures Subcommittee and Other Interested Persons" states that it appears that Revision 1 of the ERG and background documen,ts do provide an adecua basis for generically identifying information and control needs.
The licensee should describe specifically how it is intended to accomplish Items 2, 3, and 4 of the April 5,1984 Memorandum, which is reproduced in Appendix A to this report.
Examples of the pre-printed forms that VEPC0 will use to record the data are illustrated in the plan in Fig.1, Task Sequence Chart, and Fig. 2, Task Data Form.
Terminology to be used on the forms will be selected from the Standard Data Base Entries of Fig. 3, and Standardized Behavior Verbs in hierarch order, Fig. 4. The forms appear to be functional and well designed for easy The format provides easy computer entry.

The licensee should be aware that operator information and control needs should be determined from the system function and task It is recuirements important to such a those specified in the generic and plant-specific ERGS.
recognize that information and control reouirements should be derived fr analysis of system function and task recuirements; not from existing instruments and controls that are installed in the control room.
It is not clear from the VEPC0 Program Plan what process will be used to identify the operator information and control needs that are associated wit each task.
An objective, independent determination of the operator information and control needs for each operator task should be done before instrumen Review of the sample forms provided in control specifications are developed.
the Program Plan does not indicate that an objective identification of ope informaton and control needs will be accomplished or adeouately document 11
r The licensee should closely review the task analysis methodology to ensure that operator information and control requirements to perform operator tasks are determined and documented to support the specification of instruments and controls. The Program Plan does not as yet describe this process in sufficient detail to determine that the VEPC0 DCRDRs for Surry and North Anna will meet the requirement of NUREG-0737, Supplement 1, to perform function and task analyses to identify operator tasks and information and control recuirements during emergency operations.
Control Room Inventory Supplement I to NUREG-0737 requires the applicant to make a control. room inventory and to compare the operator information and control needs determined from the task analyses with the control room inventory to determine missing controls and displays.
Section 4.5 of the DCRDR describes a very complete and systematically organized plan to develop a comprehensive listing of instruments, controls and ecuipment contained in the Surry and North Anna CRs. Data collected will be placed in the VEPC0 data base.. management system in five files:
o System instrumentation a System manual controls o System automatic controls o Annunciator system o
Miscellaneous CR instrumentation and controls and operator equipment.
In each category, a complete collection of equipment locations, types, parameters, and other characteristics are described and planned to be filed Where appropriate, the following will also be included:
for later retrieval.
o Component photograph or drawing, if available o Photomosaic location code o Surveys and checklists applied to component o identification of HEDs written' for component, if any.

The inventory will be made plant-specific throuch photomosaics and visits to The licensee should be made aware that simulators, the CR and/or simulators.
if used for inventory purposes, must be exact duplicates of the CRs, and this should be confirmed in the Summary Report.
The licensee should ensure that the DCRDR objectively compares information and control needs throughout the control roomw 'ith a control room inventory to identify missing controls and displays. An objective comparison is needed to fulfill the requirement of Supplement 1 to NUREG-0737 for comparison of operator information and control needs with the control room inventory.
When conducted and documented as described, we conclude that the licensee will meet the requirement in Supplement 1 of NUREG-0737 to compare acceptably determined operator information and control needs with a CR inventory.
Control Room Survey Supolement 1 to NUREG-0737 requires that a control room survey be conducted to NUREG-0700 identify deviations from accepted human factors principles.
The provides guidelines and criteria for conducting a control room survey.
objective of the control room survey is to identify for assessment and possible correction, the characteristics of displays, controls, equipment, panel layout, annunciators and alarms, control room layout, and control room a e ient conditions that do not conform to good human engineering practices.
Section 4.3 of the DCRDR plan states that NUREG-0700 will provide the specific and detailed criteria to which all survey data will be compared. .
The licensee CR survey plan will be executed using 14 individual specific task plans. Each task plan covers an individual area which parallels the structure Each task plan uses an appropriate mix of one or more of Ch. 6 of NUREG-0700.

of NUREG-0700 and satisfy the requirement of Supplement 1 to NUREG-0737 to conduct a CR survey to identify deviations from accepted HF principles.
Assessment of HEDs _
Supplement 1 to NUREG-0737 requires that HEDs be assessed to determine HEDs are significant and should be corrected.
The basic procedure to be employed in selecting HED corrective actions described by the plan is based on Exhibit 4-2 of NUREG-0700 and NUREG-08 The process is as, follows:
draf t of October 1981.
o Assess extent of deviation from NUREG-0700 guidelines o
Estimate increase in human error for the discrepancy o
Determine if discrepant component is safety function related o
Determine if errors in using discrepant component (s) could lead to violation of tech specs or unsafe operation o Assign category and priority, based on the above.
15
They HEDs identified during the review period will be assessed by those the HEDAT.
will separate those HEDs that are unlikely to degrade performance from that may degrade performance.
The assessment factors used will be estimations of: a) the potential for operator error, b) the consequences of the errors and c) the probability of error recovery.
The estimates of the potential for error will be based on the expert judgm of the lead HF specialist, and will consider o
Component design factors (e.g., extent of deviation from guideline, conformance to plant design conventions),
o Task factors (e.g., difficulty, frequency, time demands), and o
Human factors (physical performance; sensory and perceptual performance; cognitive performance).
Figure 5-1 of the plan Error consequences will be estimated by the HEDAT. l ting provides nine classes of HEDs to aid the HEDAT in analyzing HEDS a appropriate corrective actions.
Documented errors or HEDs that are identified as being safety related or which increase the probability of an error tha could result in unsafe operation or violation of a technical specification will receive the highest rating.
HEDs will be selected to be corrected by enhancements, operator trainin Cost benefit procedural revisions, and/or design improvement alternatives. The analyses will be made to limit the number of changes which must be licensee should objectively explain and justify the rationale used to lea safety significant fiEDs partially corrected or uncorrected.
l We expect that an acceptably executed and documented I toassessme enable the licensee to demonstrate that this requirementldofbeSuppleme NUREG-0737 to assess HEDs to determine which are significant and sh corrected has been met.
16
Selection of Desian Imorovements Supplement 1 to NUREG-0737 requires selection of control room design improvements that will correct significant HEDs.
It also states that improvements that can be accomplished with an enhancement program should be done promptly. An unacceptable schedule of implementation is defined in the "Near term corrective Glossary on page 1-17 of the Plan, where it is stated:
actions . . . will be completed by the end of the second refueling outage after submittal of the final Summary Report and after NRC acceptance."
The plan states that the selection of HED corrective actions involves the following:
o Analysis for correction by enhancements o Analysis for correction by design alternatives o Assessment of the extent of correction.
It is planned that the HEDAT will -identify potential corrective actions for all HEDs, regardless of their priority.
Those HEDs selected for correction by enhancement will be reassessed for effects on operator performance and, if appropriate, will be re-evaluated via checklisting and task analysis to verify HF suitability.
If not suitable for correction by enhancement, HEDs will be corrected by design alternative.
Factors used to identify HED design alternatives will include reference to task analysis data, constraints due to equipment availability, scheduling, coordination requ'irements, cost, impact on operator training, plant main-Alternatives will be verified by functional and tenance and documentation.
task analyses and reapplication of NUREG-0700 guidelines.
It is recommended that the licensee use cost with objective restraint and discretion in the determination of corrective actions so as to ensure that HEDs will not be inadequately ~ corrected.
17
It Th'e extent to which HEDs will be corrected will be reviewed by the HEDAT.
is stated that, ideally, all discrepancies should be fully corrected, but any that are not fully corrected will be identified, documented, and justified.
The corrective action implementation schedule will consider the following:
o Prioritization and categorization guidelines of Paragraph 5.2 of the Plan ..
o Safety consecuences of operator errors that could be caused by the discrepancy o Integration with other NUREG-0737 Supplement 1 programs o Plant operation constraints o Operator training / retraining requirements o Outage schedules o Equipment procurement schedules.
We conclude that when the plan is executed and reported as described the licensee will meet the recuirement of Supplement 1 to NUREG-0737 to select However, the design improvements that will correct significant HEDs. ;
i'mplementation will not be acceptable unless all corrective actions are completed on a schedule acceptable to the NRC.
Verification that Desicn Improvements Provide Necessary Correction and Do Not Introduce New HEDs Supplement I to NUREG-0737 recuires that the licensee verify that selected design improvements will provide the necessary correction and will not introduce new HEDs.
18
The Program Plan does not specifically address these issues as separato However, certain sections of the plan include statements relative elements. Some examples follow:
to satifying these requirements.
"Where appropriate, the control room simulator will be P g. 5-8 5.3.5 utilized to test corrections required on various panels," and "this... effort affords an opportunity to look for possible violation of other HF criteria resulting from the original correction."

P g. 1 -15 1.3.5 "...all HED resolutions will be evaluated to .
each resolution is complete and adequate."
We conclude that the execution of the licensee's plan as described will m We recommend that the licensee be reouested to provide this requirement. f sufficient detail in his Summary Report to describe the steps taken these requirements of Supplement 1 to NUREG-0737.
Coordination of Control Room Improvements With Other Procrams_
Supplement 1 to NUREG-0737 requires that control room improvemen coordinated with changes from other programs; e.g, Safety Parame System (SPOS), operator training, Regulatory Guide 1.97 (R. G Emergency Operating Procedures (EOPs).
19

Guides in developing the Program Plan and ha dedicated the necessary resources to ensure the success of the CRDR projec However, except for a few brief nonspecific statements in other parts d of the plan, there is no description of how the coordination effort will proceed, an who is responsible'for executing and recording it.
Because the specific methods and procedures planned to be used for the coordination effort are not discussed, we recortrnend that the licensee be requested to provide descriptions which will ensure that design improvements introduced as the result of other control room improvements are reviewed to meet the same standards of good human factors engineering as improvemen The licensee will need to provide evidence of these result from the DCROR.

Conclusions .
Based on our review of the VEPC0 Surry/ North Anna DCROR Program Plan, w conclude that VEPCO plans to conduct a DCROR that generally meets the However, there are several areas in the plan of Supplement 1 to NUREG-0737. They are:

MEETING
SUMMARY
- TASK ANALYSIS REOUIREMENTS OF SUPPLEMENT 1 TO NUREG-0737 MARCH 29,1984 MEETING WITH WESTINGHOUSE OWNERS GROUP (WOG) PROCEDURES SUBCOMMITTEE AND OTHER INTERESTED PERSONS Staff representatives met with representatives of the WOG Procedures Subcommittee and others on March 29, 1984, to discuss the task analysis requirements of Supplement 1 to NUREG-0737 (Generic Letter 82-33). The purposes of the meeting were (1) for the Subcommittee to discuss how operator information and control needs have been addressed by the Emergency Response Guideline (ERG) development effort, and (2) for the staff to identify any additional analysis or documentation needed for review.
Mr. Doug McKinney, Subcommittee . Chairman, made a brief presentation. on the background of the ERG development program as it relates to the issue of task analysis. His presentation included a description of the ERG background documents, development of Revision 1 to the ERG, interactions with NRC, Supplement 1 to NUREG-0737 requirements, and an overview of how the WOG had responded to the reouirements. A copy of Mr. McKinney's transparencies is enclosed (Enclosure' l).
Mr. Ralph Surman of Westinghouse made a presentation which described in some detail the development of the ERG and the accompanying background He emphasized that documentation for both the Basic version and Revision 1.
one of the main objectives of the ERG is to identify the operator tasks necessary to perform functions which are identified in the background documentation. A copy of Mr. Surman 's transparencies is enclosed as Enclosure 2.
After a caucus, the staff made the following comments to the meeting attendees:
(1) Based on the presentations by Mr. McKinney and PE. Surman, it appears that Revision 1 of the ERG and background documents do provide an adequate basis for generically identifying information and control needs.

- (2) Each licensee and applicant, on a plant-spgcific basis, must describe the process for using the generic guidelines and background documen-tation to identify the characteristics of needed instrumentation and controls. For the information of this type that is not available from the ERG and backround documentation, licensees and applicants must describe the process to be used to generate this informaton (e.g., from transient and accident analyses) to derive instrumentation and control characteristics. This process can be described in either the PGP or DCRDR Program Plan with appropriate cross-referencing.
(3) For potentially safety-significant plant-specific deviations from the ERG instrumentation and controls, each licensee and applicant must provide in the PGP a list of the deviations and their justification.
These should be submitted in the plant-specific technical guideline portion of the PGP, along with other technical deviations.
(4) For each instrument and control used to implement the emergency operating procedures, there should be an auditable record of- how the needed characteristics of the instruments and controls were determined. These needed characteristics should be derived,from the information and control needs identified in the' background documentation of Revision 1 of the ERG or from plant-specific information.
(5) It appears that the Basic version of the ERG and background documentation erovide an adequate basis for generically deriving information and control needs. However, because of the differences in the organization of the material in the background documents between Basic and Revision 1, it is apparent that it would be easier to extract the needed information from the Revision 1 background documents.
At the conclusion of the meeting, there was general agreement with the staff's coments among the owners' representatives present.
Enclosure 3 is a list of attendees.
