AUDIT PLAN FOR F

EVALUATION OF THE SEABROOK STATION SAFETY PARAMETER DISPLAY SYSTEM BACKGROUND All holders of operating licenses issued by the Nuclear Regulatory Commission (licensees) and applicants for an operating license (OL) must provide a Safety Parameter Display System (SPDS) in the control room of their plant.

The Commission approved requirements for the SPDS are defined in Supplement 1 to NUREG-0737.

The purpose of the.SPDS is to provide a concise display of critical plant variables to control room operators to aid them in rapidly and reliably determining the safety status of the plant.

NUREG-0737, Supplement 1, requires licensees and applicants to prepare a written safety analysis describing the basis on which the selected parameters are sufficient to assess the safety status of each identified function for a wide range of events, which include symptoms of severe accidents.

Licensees and applicants shall also prepare an implementation plan for the SPDS which contains schedules for design, development, installation, and full operation of the SPDS as well as a design verification and validation plan.

The safety analysis and the implementation plan are to be submitted to the NRC for staff review.

The results of the staff's review are to be published in a safety Evaluation Report (SER).

Section 18.2 of NUREG-0800, " Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants," describes how the staff performs SPDS reviews for applicants of operating licenses.

The staff's review process will evaluate the (1) safety analysis report, (2) the implementation plan, and (3) the verification and validation (V&V) plan.

In addition three separate audit meeting / site visits, as described below, may be arranged through the Licensing Project Manager.

As dictated by the comprehensiveness of the applicant / licensee's

' documentation and the schedule for design ar.d implementation of the SPDS, the objectives of the audits may be met in fewer site visits.

Design Verification Audit:

The purpose of this audit meeting is to obtain additional information required to resolve any outstanding questions about the Verification and Validation Program, to confirm that the V&V Program is being correctly implemented, and to audit the results of the V&V activities to date.

At this meeting the applicant should provide a thorough description of the SPDS design process.

Emphasis should be placed on how the applicant is assuring that the implemented SPDS will:

provide appropriate parameters, be isolated from safety systems, provide reliable and valid data, and 1

- \\

~

incorporate good hum:n factors engineering prcctica.

D'esign Validation Audit:

After review of all documentation, an audit may be conducted to review the as-built prototype or installed SPDS.

The purpose of this audit is to assure that the results of the applicant or licensee's testing demonstrate that the SPDS meets the functional requirements of the design and to assure that the SPDS exhibits good human factors engineering practice.

Installation Audit:

As necessary, a final audit may be conducted at the site to ascertain that the SPDS has been installed in accordance with the applicant / licensees plan and is functioning properly.

A specific concern is that the data displayed reflect the sensor signal which measures the variable displayed.

This audit will be coordinated with and may be conducted by the NRC Resident Inspector.

Based upon the advanced state of the design a combined Design Verification and Design Validation audit is planned for May 20-21, 1986.

1 NRC AUDIT TEAM The NRC Audit Team will consist of a representative from the PWR-A Electricel, Instrumentation and Control Systems Branch, assisted by two consultants from the Lawrence Livermore National

)

Laboratory (LLNL).

PSNH SUPPORT NJ2DED l

The following personnel should be available for discussions with the audit team:

The person having lead responsibility for SPDS design and implementation, Engineering and/or vendor staff familiar with all aspects of SPDS design and operation, Representatives of Operations, Maintenance and Training departments, Representatives of the software development team, Representatives of the System Verification and Validation

team, Representatives of the human factors design / review staff, Plant operators designated as SPDS users.

AGENDA l

~

SEABROOK STATION l

SPDS AUDIT DAY 1:

8:30 A.M.

NRC entrance briefing and introductions.

8:40 A.M.

Overview of SPDS design program and current status by by PSNH including:

9# pt

8.. /

Boundaries of the SPDS with respect to the

~.

o plant computer, o

Human factors analysis, standards, and criteria used in the design process with emphasis on plant specific considerations, o

System reliability and availability:

Design characteristics to insure high availability, Methods used to estimate system availability, Methods planned to monitor operational availability.

o Data validation methodology used in the SPDS including data validation performed by any necessary supporting systems that provide validated data to the SPDS. (possible examples are RVLIS and radiation monitoring),

o Operator training in use of the SPDS, o

System maintenance philosophy and staffing.

10:30 A.M. Description of Verification and Validation (V&V)

Program including:

o Description of the VEV team and discussion of the degree of independence from the design

team, o

Scope and depth of the V&V program, 4

,l

^

o Test cases for validation of SPDS paramaters j

and how they demonstrate the representativeness and useability of the selected parameters for evaluating transient conditions that do not fall within the plant design basis, o

Discussion of Emergency Response Guideline Validation Program and applicability to the Validation of the Seabrook Station SPDS, o

Verification of human factors aspects of

system, o'

Coordination with other NUREG-0737 initiatives, with emphasis on control room design review (including a short discussion of SPDS related findings),

o Overview of SPDS V&V documentation.

2:30 P.M. NRC questions and review of V&V documentation.

As part of the V&V documentation review the audit team will want to select sample SPDS requirements and trace their implementation through hardware and software specifications, algorithms and integrated system performance.

The audit team will review documentation of verification and validation activities for each step.

To support this review all existing system documentation in the following categories should be available for the SPDS and for any necessary supporting systems that provide validated data to the SPDS.

o System functional requirements documents, o

Hardware and software specifications, o

Algorithm descriptions, and source code, o

Emergency operating procedures, o

System availability study, o

Data validation "setpoints",

o Software and hardware verification test procedures and results, o

System validation test procedures and

results, 5

o System installation test procedures and

results, t

o Documentation of independent verification reviews of functional requirements documents, hardware and software specifications, algorithms, test procedures and results, o

Drawings that document the make, type, and electrical connections to the SPDS electrical isolation devices.

This portion of the audit may extend beyond normal working hours.

PSNH's participation in the documentation review may be limited to one or two individuals who can answer most audit team questions about the system hardware, software, and the V&V process.

DAY 2:

8:30 A.M.

Identification of outstanding questions resulting from the V&V documentation review.

i 9:00 A.M. NRC human factors audit of displays, display formats, control devices, access and response times.
