5'CMMARY AND RECDMMENDATIONS The Surry/North Anna ERF conceptual design package does not contain sufficient information on the TSC, EOF, osc or control room to al.low evaluation of the emergency re~nse facilities.

The areas which lack the most info~tion are as follows:

The TSC is located within 2 minutes walking distance to the control room and is sized sufficiently.. However further details are needed to determine whether ea.ch work station is equipped for its function.

The licensee did not provide sufficient detail concerning TSC habitability to perform an evaluation.

The subject of TSC staffing was not sufficiently addressed..

Although the design document addresses the subject of primary voice communications for the TSC, the backup communications were not addressed. Also the licensee did not address the subject of additional dial telephone lines for use by NRC personnel or what provision was made for 24-hour per day notification to the State/local emergency r~nse network.

The design package did not address procedures in the TSC which will ensure records are current and complete.

No information was provided concerning the control room or

csc.

The location of the EOF in Richmond facilitates all of the required fmctions except the direct supf()rt of offsite monitoring teams.

The design package provided no information to determine whether the EOF structure would be able to withstand reasonable expected adverse conditions.

The subject of EDF staffing was not sufficiently addressed.

Insufficient information was provided availability and management at the EDF.

on recor&

For the data acquisition and display system the design package describes the licensees interim system and two alternatives for the final system. The interim system utilizes the existing Plant Ccmputer System with the data being obtained Page 1-1

Surry/North Arma through the intelligent remote multiplex system (IRMS) which consists of remote

smart multiplexers and a communications processor to provide data to the non-graphic black and white CR!'

tetminals. For the final system the licensee proposes two alternatives. The first alternative would involve replacement of the existing plant process computer with a fully networked distributed computer system. which would perfor:m both plant process functions. and ERF functions.. The other alternative proposed - is* to install a dedicated Emergency Resp)nse Facilities I/0 (ERFIO) processor. Although the design package provides general statements on the proposed systems, the figures and text do not include enough specific information to allow for an informed evaluation. -The areas which lack the most information are as follows:

Detailed equipnent specifications were not provided for the data aa;ruisition system and the displays.

The design package stated that 11necessary parameters of those specified in-Regulatory Guide 1.97, Rev.

2 and Regulatory Guide 1.23" will be provided. No inform~tion was provided to indicate what 11necessary1' parameters includes.

Data parameters provided are inadequate.

The design package states that CRT displays ~ou~d inc~ude preset and call-up types. However, more detail 1s_requ1red concerning the display formats and the operator interface*

requied to initiate +he di'splays.

The licensee does not intend to have an SIDS display in the EDF.

The licensee provided no detail on

. intersystem data communications apd other subsystem interconnections.

An adequate evaluation would. necessitate analysis of data transmission facitlites and interactions throughout the ERF including aa;ruisition of sensor data, routing through multiplexors and traffic to display devices.

The licensee addressed the NOL provisions adequately.

General statements about a verification, validation, and revalidation plan were made but no other system supy;:ort requirements were addressed..

The licensee claims they will meet the *reliability requirement but provide no details to verify this claim.

2. TECHNICAL &JPEORl' CENTER 2.1 Integration with overall Planning

1. The design of the Technical Supp::,rt Cepter (TSC) addresses the fallowing-goals:

a. Provides plant management and technical SupfX)rt to plant operations personnel during emergency conditions; bo Relieves the reactor operators of peripheral duties and communications not directly related to reactor system manipulations;

c. Prevents congestion in the control room; and

d. Performs EOF functions for the Alert Emergency class and for the Site Area Emergency class and General Emergency class until the EDF is functional.

2. The TSC shall be the emergency operations work area for designated technical, engineering, and senior licensee plant management personnel; any other.

licensee-designated personnel required to provide the needed technical supp:,rt; and a small staff*of NRC personnel.

3. The TSC shall have facilities to supp:,rt the plant management and technical personnel who will be assigned there during an emergency *and will be the primary onsite communications center for the plant during the emergency.

TSC personnel shall use the TSC data system to.

analyze the plant steady-state and dynamic behavior prior to and throughout the course of an accident. The results of this analysis will be used to provide guidance to the control room operating personnel in the management of abno:cmal conditions and in accident mitigation. TSC personnel will.

also use the environmental and Page 2-1 Adequate reSP')nse o Subject not addressedo Adequate res{X)nse.

A functional block diagram, showing the facilities to be used for data acquisition and their functional interconnection to ERF's and other plant facilities should be provided. Figures 2 and 3 of NUBEG-0696 are examples of such diagrams.

6.2 DAS Facilities It is anticipated that a dedicated data acquisition system, consisting of a single facility or a functionally integrated, physically distributed facility will be proposed for most sites.

However, NUREG-0696 does not require that utilities provide

specific, dedicated DAS facilities, only that they perform specific data a~sition functions.

Some sites may proi::ose to perform DAS functions by sharing. other facilities such as the plant process control computer. In either case; any facilities used for the acquisition of any and all data relating to safety parameters and ERF's should address the.following areas.
