2.3 CAPABILITIES REQUIRED TO ACHIEVE PURPOSE 2.3.1 Data Set Sensors which supply information to the Control Room and other monitoring systems (such as the Transient Test System) are read by the ERFIS. Care is taken to ensure that the operation or failure of components of the ERFIS cannot introduce a higher degree of uncertainty into a signal which is transmitted to another system. The Effluent Monitoring and Meteorological Systems are intelligent systems which also supply data via a communication link. The ERFIS is also capable of handling manual (keyboard) data entry. | 2.3 CAPABILITIES REQUIRED TO ACHIEVE PURPOSE 2.3.1 Data Set Sensors which supply information to the Control Room and other monitoring systems (such as the Transient Test System) are read by the ERFIS.

1.0 EMERGENCY RESPONSE FACILITIES (ERF)
1.1 INTRODUCTION
This document presents the functional requirements of the Emergency Response Facilities (ERF) for Grand Gulf Nuclear Station.
The ERF consists of six subsystems.
- 1. The Emergency Response Facility Information System (ERFIS)
- 2. The Safety Parameter Display System (SPDS) l 3. The Technical Support Center (TSC)
! 4. The Emergency Operations Facility (EOF) t
- 5. The Nuclear Data Link (NDL)
- 6. The Operational Support Center (OSC)
The ERF Information System is a dedicated data acquisition and computer system which supports the other subsystems. The total ERF system has been configured to comply with the design objectives established in NUREG-0696.
1.2 ERF SYSTEM FUNCTIONAL REQUIREMENTS The ERF shall provide the emergency preparedness required by NUREG-0696. The ERF subsystems shall operate in a complementary manner to enhance the management and control of plant emergency response capabilities.
The ERF system shril provide responses to these classes of emergencies as defined by NUREG-0654:
- 1. Notification of unusual event
- 2. Ale.t
- 3. Site area c ,ergency
- 4. Generr.1 emergency Activatica of the ERF is determined by the Emergency Plan.
2.0 EMERGENCY RESPONSE FACILITY INFORMATION SYSTEM (ERFIS) 2.1 PURPOSE The ERFIS (Fig. A) will acquire, store, process and present data to the SPDS, the EOF, the TSC, and the NDL (when implemented). The SPDS, EOF, TSC and NDL are Emergency Response Facilities required by the NRC (NUREG-i(96),
(1)
f 2.2 DATA POINTS TO BE MONITORED NUREG-0696 indicates that Regulatory Guide 1.97 defines the types of data points (indicators) to be monitored. The list of ERFIS parameters in Appendix A was developed using Regulatory Guide 1.97 as guidance.
2.3 CAPABILITIES REQUIRED TO ACHIEVE PURPOSE 2.3.1 Data Set Sensors which supply information to the Control Room and other monitoring systems (such as the Transient Test System) are read by the ERFIS. Care is taken to ensure that the operation or failure of components of the ERFIS cannot introduce a higher degree of uncertainty into a signal which is transmitted to another system. The Effluent Monitoring and Meteorological Systems are intelligent systems which also supply data via a communication link. The ERFIS is also capable of handling manual (keyboard) data entry.
2.3.2 Availability The unavailability of the ERFIS is calculated to be less than .01 where failure is defined as a total loss of system capability not due to scheduled maintenance, loss of power supplies, or failure of data acquisition equipment.
Power for the ERFIS is supplied from the Plant Uninterruptible Power System (except for the EOF portion) and therefore the power supply is as reliable as the power supplies for the Control Room instrumentaton. (The power supply for the EOF portion of the ERFIS is described in Section 5.)
The unavailability of the SPDS in the Control Room is less than .01.
2.3.3 Data Storage Values are stored on fixed length disc records for up to 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />. This leaves at least 2 1/2 hours after an event before operator attention is required to start the tape recorder. This will meet the requirement to record data which was on the disk 30 minutes before an event.
2.3.4 Data Display and Communication The ERFIS provides three data display services:
the TSC subsystem, the EOF subsystem, and the SPDS subsystem. The TSC subsystem is capable of user-formatted ' display iucluding plots on the same axis (three variables with respect to time), change (2)

of unito, crpsnaien of scale, ability to plot rny partmeter as a functica of another, and listings.
Output can be provided on both a CRT and a printer / plotter. A keyboard is provided for commands and user-developed software. The E0r display subsystem will have the same capabilities as the TSC display subsystem.
The SPDS display subsystem provides preformatted trends and tabular listings on dedicated CRTs in the Control Room, the TSC, and the EOF. These displays are available through single pushbutton commands. Each SPDS console operates independently.
Data may also be supplied to an NDL formatting module. This would be an intelligent module.
Capabilities of the NDL Formatter / Communication System have not been fully defined. Definition of the NDL will require further clarification from the NRC.
2.3.5 Equipment List Appendix B provides a list of major equipment to be used in the ERFIS.
2.3.6 Dynamic Loading The capability of the ERFIS components to withstand dynamic loads shall be consistent with sound engineering principles. The components will be securely mounted, and they have been shown to be sturdy enough to operate in industrial environments.
2.4 ENVIRONMENTAL 2EQUIREMENTS, LOCATION Appendix C describes the locations for equipment in the Computer Room in the control building, size, HVAC load, and l power requirements.
2.5 IMPLEMENTATION SCHEDULE l The ERFIS described will be made operational on a schedule to be determined in NUREG-0737.
3.0 SAFETY PARAMETER DISPLAY SYSTEM (SPDS)
'I. PURPOSE l
l The SPDS shall provide displays of plant parameters from l which the safety status of operation may be assessed in the Control Room, the TSC and the EOF. The displays in the Control Room shall be designed to help Operations personnel make quick assessments of the plant safety status.
SPDS display units shall also be located in the TSC and EOF for engineering and management decision information.
(4)
3.2 DATA POINTS TO BE MONITORED The SPDS monitors a subset of the ERFIS parameters.
These points were specified if:
- 1. The variable, if off-limits, is an indicator that plant operation should be under the Emergency Operating Procedures, or,
- 2. The variable is an aid to Operations to assess plant safety conditions.
SPDS parameters are indicated in Appendix A.
3.3 DESIGN The SPDS is an ERFIS data display service. Information is displayed on CRTs in the Control Room, the TSC, and the EOF. All of the displays are preformatted and independently selectable at each station by one pushbutton command for each display. ,
3.3.1 Human Factors Human factors were considered in the design of the displays and equipment. The data refresh interval is 2 to 5 seconds depending on the complexity of the display. The displays are to be simple tabular lists or trends providing limits based on plant op* :ating modes. The use of symbology is consistent, and the displays have been designed considering human ~ factors engineering principles with special consideration to operator's use. .
All operator commands and mode selection require only one pushbutton. 'A visual cue and audible alarm are provided when parameters exceed limit values or validation fails.
l If the alarmed SPDS parameter is not on the d! splay which was selected, notation is made on the selected display to refer to the display which shows the alarmed parameters.
If no specific display is selected, the SPDS will generate each display sequentially, on a continuous basis.
3.4 LOCATION Tha location of the SPDS in the Control Room is shown on Fig. B. This position was chosen so that the SPDS will be visible from the Supervisor's console and the Operator's console. The display will be rotatable to be visible from the shutdown board (P601).
