AUDIT PLAN FOR EVALUATION OF THE NINE MILE POINT 2 SAFETY PARAMETER DISPLAY SYSTEM Back round Staff evaluation of safety parameter display systems (SPDS) consists of reviews of the applicant/licensee's documentation (i.e. safety analysis report and implementation plan) and audit meetings/site visits.
Three separate audit meetings/site visits, as described
- below, may be arranged through the Division of Licensing Project Manager.
As dictated by the comprehensiveness of the applicant/licensee's documentation and the schedule for design and implementation of the SPDS, the objectives of these 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 (VIV) Program, to confirm that the V8V Program is being correctly implemented, and to audit the results of the V5V 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 incorporate good human factors engineering practice.
Design 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/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/licensee s 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 on the advanced state of the Nine Mile Point design, the staff plans to do a combined Design Verification and Design Validation audit at a mutually agreeable date.
Audit Schedule The staff anticipates that thi
~ will take two full days.
After reviewina this agenda the applicant should propose an appropriate date for the audit.
The staff will attempt to accommodate any reasonable date between April 15 and September 30, 1985.

NRC Audit Team The NRC Audit Team will consist of representatives from the Human Factors Engineering
- Branch, Procedures and Systems Review Branch, and from the Instrumentation and Control Systems Branch.
In addition, the staff will be assisted in the audit by Lawrence Livermore National Laboratory (LLNL).
~Aenda Day 1:
8:30 AM-10:30 AM Introductions, short entrance briefing (10 minutes) by NRC, overview of SPDS design program and current status by Niagara Mohawk including:
1) human factors analysis, standards, and criteria used in the design process, with emphasis on plant-specific considerations used to modify the BWROG design 2) 3)
reliability - a) design characteristics b) methods used to estimate reliability data validation methodology used in SPDS and necessary
.supporting systems, i.e.,; Digital Radiation Montiroing System (DRMS) and Gaseous Effluent Monitoring System' (GEMS).
10:30 AM-2:30 PM (one hour break for lunch during this period) 2:30 PM-4:30 PM Description of Verification of Validation (VEV) program including:
1) description of V8V team and demonstration of independence from the design team 2) available documentation for completed tasks and phases 3) test cases for validation of SPDS parameters and how they demonstrate the representativeness and useability of selected parameters 4) human factors aspects 5) plans for or results of dynamic simulator testing NRC questions and review of V8V documentati.on

Day 2:
8:30 AM-9 30 AM Short tour of control room or simulator 9:30 AM-12:00 PM 1 00 PM-3:30 PM 3:30 PM 4:00 PM Demonstration of SPDS page formats in TSC/EOF/Simulator.
Walk-through of a plant-specific scenario* that involves confirmation of containment isolation, monitoring of area radiation level and trend, and monitoring of gases releases.
NRC audit of displays, display formats, interface devices, access and response times, etc.
NRC caucus Exit briefing
- The applicant should develop this scenario'.
The scenario should be walked-talked through by an operator that has been familiarized with SPDS operation.
Upgraded emergency operating procedures should be used for the walk-through.
