Attachment 1 to this letter responds to the specz.fic requests of the Generic Letter.
Three response facilities have been established, the opera-tional support center (OSC), the technical support center (TSC),
and the emergency operations facility (EOF).
The OSC is located in the Turbine Building in the auxiliary operators office.
The OSC has been previously described in our letter of December 28, 1979.
The OSC has been completed.
The permanent TSC will be located near the control room in the second story of the condensate demineralizer (or AVT) building.
This facility has previously been described in our letter of December 28, 1979 and is further described in Attachment 2.
This p facility is nearly ready for occupancy as the TSC.
The EOF is located in the RGSE main offices.
This facility ~jE has previously been described in the Nuclear Emergency Offsite
Response
Procedure which was transmitted by our letter to you s&o 0M'g~'ated February 27, 1981.

It is expected that Bidder's will respond with a proposal delineated by his scope of supply appropriately modified to meet the special requirements of this Specification.
~
Each bid must conform to this Specification unless specific exceptions are listed in the proposal.
The number of such exceptions should be minimized by the Bidder so far as possible.
Exceptions deemed necessary by the Bidder shall be clearly itemized in a separate and distinct section of his proposal.
If conflicts exist between the proposal and the material contained within this Specification, and said conflicts are not listed as "Exceptions" as prescribed
- above, the requirements set forth in this Specification shall govern.
The Bidder may submit alternative or optional features for consideration by the Purchaser.
The Appendices list the information to be included in the proposal, as desired by the various companies, in addition to that requested by this common Specification.
Each company intending to submit a proposal in accordance with this Specification shall inform the Purchasers in writing fourteen (14) days after issuance of inquiry.
Each company indicating its intention to submit a proposal will be placed on an official list of Bidders and will receive such additional data and changes as may be released by Purchasers and will be invited to attend Bidders'onferences.
~
Should a Bidder find any discrepancies, or question the meaning or intent of any portion of this Specification, the Bidder may request clarification from Purchasers, in writing, at least twenty-one (21) days before bid submittal deadline.
Purchasers will respond within ten (10) days after receipt of question.
Answers to each Bidder's questions will be forwarded to all Bidders.
In the event of conflict between the common portion of this Specification and the respective company's Appendix, the respective company's Appendix shall govern.
1.2 Summar Descri tion of Com uter S stem The computer system required is expected to be configured of sufficient computers to service the unit(s) at each plant at the desired level of availability.
Bidder is requested to propose a computer configura-tion similar to that on attached diagram but may suggest alternate configurations which satisfy the Purchaser's redundancy/availability requirements.
Th'e Safety Assessment System (SAS) consists of all hardware shown on the block diagram above the dashed line marked "NUREG-0696".
The Process Computer System is that hardware below this line.
The SAS computer is designed not only to fulfillthe requirements outlined in.NUREG-0696, but also serve as a high reli-ability "front-end" for the plant process computers.
The attached block diagram does not detail all the specific peripherals required for support of the SAS and plant process computers.
Such items as programmers console and magnetic tape units should be included by the Bidder as necessitated by this Specification.
'S l
Page 3
This Specification is divided into three sections:
- 1) General Requirements,
- 2) Functional and Technical Requirements for SAS, and 3)
Functional and Technical Requirements for Plant Process Computer.
The Bidder is requested to submit.
a proposal covering both the SAS and Plant Process computer systems.
It is the Purchaser's intention, however, that if the Purchaser requests it, (see appropriate Appendix),
that the SAS may function by itself without the presence of the Plant Process Computer.
Because Purchaser's requirements for processing and/or computational capability may increase in the future, it is requested that proposals reflect Bidder's ability to expand his proposed systems in these areas.

SAFETY ASSESSHENT SYSTEH 1.0 GENERAL 1.1 Part II of this Specification describes the functional and technical requirements for the Safety Assessment System (SAS).
The general requirements outlined in Part I apply also to the SAS.
1.2 The purpose of the SAS is to:
Provide the safety-related operator displays required by NUREG-0696 in the control room,
2 ~
Serve as the data acquisition system for not only the SAS but also the plant process computer system.
2.0 FUNCTIONAL RE UIREHENTS DESCRIPTION 2.1 Safet Assessment S stem Functions The following description of the SAS is provided for the purpose of illustrating the system hardware requirements.
A software specifica-tion and development of the software itself for the SAS will be ob-tained by the Purchasers under a separate contract.
This software, including the necessary algorithms, human factors considerations and common, high level language programming, will then be made available to the Contractor for his incorporation into his software such that the functional requirements described in this specification are met.
Software development and implementation, however, for the SAS operat-ing system, data-acquisition and parameter passing to the plant process computer shall be the responsibility of the Bidder.
2.2 Safet Assessment S stem The Safety Assessment System is a computer based system that will aid the operator in determining safety system status (pre-and post-accident) and accident identification.
The major features of a typical Safety Assessment System are described below.
Displays of at least nine key parameters
- six of these may be normalized bar graphs, three may be digital (but not alpha-numeric) displays.
Accident Identification Displays (AID's) graphically inform the operator of the relative probability that each of the three major accidents may be occurring (loss of coolant accident, steam generator tube rupture, and secondary system rupture).
I I pl I P
Page 25 A Safety System Ready Honitor that displays the status of safety systems during normal operation if a loss of redundancy occurs or if a loss of function occurs.
An accident mitigation monitor assesses proper safety systems functioning during an accident and will alert the operator if loss of a vital function occurs during-the course of an accident.
Graphs of at least 13 critical parameters for the last 30 minutest Historical data (30 minutes storage) foi each of the parameters (maximum of 40 parameters, minimum of 20), required for the AID's.
Displays of current values and trends of the parameters required for the AID's.
The most essential features are presented to the operator via two color CRT displays.
The first (the "normal" or pre-accident display mode) incorporates the first three features above and would be the usual display.
The AID's are yellow ver ical bar graphs whose heights represents the relative probability of occu".rence for three accidents.
The AID's occupy most cf t.".e ri~~t hand side of the display.
The normalized parameters err c:s~.
bayed on bar graphs on the left of the screen.
The digital parameters
.are displayed below the AID's alert messages.
Hessages from the safety systems ready monitor are displayed above the AID's.
2.2.1 Ke Parameter Dis la Six of the parameters that are essential to, early diagnosis of an accident are displayed on the left side of the CRT "normal mode" display.
Parameter values are normalized for for all normal operating modes operation so that their sizes are approximately equal.
The displays are bar graphs (either horizontal or vertical).
While a normalized parameter is within established limits, its bar is green in color. If a parameter is not within these limits, the bar is red.
Three additional.parameters comprise the remainder of the normal parameter display.
These may use digital or analog inputs and display.
The lower right hand portion of the CRT (page one and two) is used for this portion of the display, the information is coded green when it is within normal limits and red when it exceeds these limits.
The six normalized parameters are:
Pressurizer Pressure Pressurizer Level Reactor Coolant System Tavg Steam Generator Pressure
4
Page 26 Steam Generator Level Steam Flow-Feed Flow (Hismatch)
The three parameters that may be displayed 'digitally are:
Containment Pressure'ontainment Radiation Air Ejector Radiation Accident Identification a'nd Dis la S stem Those parameters necessary to identify the four major accidents; loss of coolant, steam generator tube rupture, inadequate core cooling and secondary system rupture, are used by the AID's program.'he magnitude of and rate of change of each of these parameters is evaluated for its importance as an identifier (symptom) of each accident...
Values are assigned accordingly and put in a "register" for each accident.
The register totals are representative of the relative probability of that accident being in progress.
The register totals may be displayed as three vertical yellow bars whose height is proportional to its register's total value.
The algorithm for assessing the relative accident probabilities will be developed by Purchasers and provided to Contractors for programming.
This display is a part of the Normal Node Display and the Accident Node Display.
The system may display at the request of the operator, a
page showing the parameters considered to be an identifier
'or the accident of interest, the current value of the parameter, the trend of the parameter (increasing, decreasing, or constant) the value currently assigned that parameter in that accident registry and the accident register total. There is a separate page for each accident.
The system should be able to operate during a normal heatup and cooldown with the AID's indicating a high accident.

The minimum requirement for a system status determination is a switch and valve lineup verification.
A broader determination of operability can be obtained by including other inputs some of which may be manual such as tank levels, pressures, temper-
- atures, chemistry, bus voltages, etc.
The method of display is an alert message on the SAS CRT.
The operator could, utilizing one of the plant process CRT's, call up the respective flow diagram, which would display to him which piece of equipment in that system is causing that system to be classified "unavailable".
The Boolean logic to compute system determination will be performed in the PPCS CPU's.
The results of this logic shall be passed to the SAS CPU's as a
contact closure generated by the PPCS and monitored by the SAS Computer.
Upon detection of contact status change the SAS computer will generate and display the appropriate message.
Accident Hiti ation Honitor This system checks certain system alignments and operation.
The monitor may be activated by a safety injection signal.
For the first 60 to 90 seconds following the activation
- signal, the monitor checks for the proper startup of safeguards equipment, including Phase A containment isolation. If an error is detected, a message such as
gl,
'L 1"
Page 28 "Safety Injection Sequencing Error" is displayed.
Through the use of a function push-button the operator may call a lower level display for additional detail.
. After 60 to 90 seconds, the monitor checks the following systems for proper operation:

If a loss of function is detected, the message "XX System Nalfunction, see page YY" is displayed.
The monitor will continue the system checks until terminated by the operator.
SI reset 'will not terminate the checks.
- Displays "Do Not Reset" message if containment pressure and radiation are high.
2'.5 Critical Parameter Trendin and Dis la The critical parameters used in developing the AID's display must also be capable of display on local and remote SAS CRTs terminals.
2.2.5.1 Parameter Graphs Four (or five) graphs of certain plant parameters should be displayed on the left side of the CRT (accident mitigations mode).
The graphs should show the trends for the past one-half hour.
This method of display facilitates prediction of plant conditions in the near future, thus aiding the decision making process.
Actual values, rather than normalized
t S

Page 29
- values, should be displayed.
In the case where the parameters may vary widely, automatic scale changes or range selection is necessary.
The parameters graphed would include:
Steam Generator Pressure (4)
Reactor Coolant Temperature Reactor Coolaiyt Pressure Primary System Inventory (Pressurizer Level andy -r Reactor Vessel Level)
Steam Generatiir Level (4)
Reactor Coolant Sub-cooling Containment Pressure 2.2.5.2 Historical Data Base Historical data of the parameters used in the AID's should be maintained for a minimum of one-half hour, with first-in/first-out storage.
The amount of main memory allocated for "his storage should be a minimum of 36K bytes.
The e"..='re data base may be printed upon operator dern,i.-M. i".'a:Ne links to the plant process computer sys ~.
<<'.iile system is transferring the historical data base
'.:;e mta base shall be "frozen".
Any new data ~hill:e entered into a new data base.
2.2.5.3 AID's Parameter Dis la s Three separate display formats are available upon command of the operator.
Each"accident in the AID's should have its own display.
Each of the identifying parameters for a particular accident is listed, along with its current value, its trend (increasing, decreasing, or constant should be indicated by up
- arrows, down arrows, or no arrows, respectively) and the current AID's value assigned it.
The AID's total is also displayed.
2.3 Nuclear Data Link The second display may incorporate the second, fourth and fifth features of Article 2.2 into the accident mode display.
The AID's occupy the same location as in the normal mode display.
The graphs of the fifth feature of Article 2.2 occupy the left half of the display and alert messages appear above the AID's in the event of a safety system malfunction (see examples in the respective Appendix).

Page 30 2.3.2 The function of NDL is to supply the NRC Headquarters with vital plant parameter values.
2.4 Push-Button Function Panel A push-button function panel shall be provided so that the operator may obtain any desired SAS display merely by depressing a single push-button.
Since the displays described in section 2.2 are not interactive, only these push-buttons are required.
2.5 Additional Safet Assessment S stem Functions 2.5.1 It shall be the function of the SAS to scan all inputs from the field multiplexors, check for limits and place point values in a common database.

Other components such. as programmer's
- console, line printer(s), magnetic tape unit(s) and/or floppy disk drives not required to support those functions in section 2.0 but used for example to load the system, run diagnostics, etc.
are exempt from the requirements of this section.

Technical Support Center June 8,
1981 The general arrangement and design details are shown on drawings 21489-362 and 181-101 with elevations and sections as shown on drawings 181-102 and 181-103.
As shown, the overall TSC is comprised of three distinct but, adjoining structures occupying approximately 7000 square feet.
The south wall is located on the north column line of the control room but one elevation lower, satisfying the "in close proximity to the control room" requirement.
The main or central facility is a one-story reinforced concrete structure placed upon the existing condensate demineralizer building (CDB), itself a concrete structure.
The central area is

- shielded, and houses the required personnel in operating and supporting areas to accomplish the primary TSC activity.
Fixed walls define those spaces which need not, afford flexibilityin their arrangement.
These spaces are the records center, a conference room, kitchen, toilet. rooms, entrance corridors and vestibules, and instrumentation, radiation monitoring and communication equipment areas.
Full height, demountable partitions enclose a
computer and the NRC office.
The display area and perimeter office space achieve definition by the use of removable partitions to provide maximum flexibilityfor alternative functions and activities.
The total area is raised approximately one (1) foot.
on an access floor to provide display cabling and utility line space in any portion of the TSC.
C
The second distinct structure is a non-shielded one-story space north of the TSC built over the remainder of the CDB. It houses the HVAC equipment and provides storage and/or office space.
The charcoal filters in the mechanical equipment room are shielded from the main TSC area.
The third distinct structure is located south of the TSC and CDB area and houses a diesel generator, uninterruptible power l
source and battery rooms.
It is a non-shielded, one-story unit built upon grade and is separated from the main TSC by an inter-ceding corridor which serves as an indoor link between the Turbine Building and the TSC's southern entrance.
Under-floor access using removable floor panels is provided in this corridor area to accommodate the extension of all display cabling from the existing relay room to the access floor beneath the TSC.
The electrical power system is designed to provide normal power and emergency power to the TSC computer and electrical equipment and is described in Attachment 1.
The physical arrangement of most of these components is shown on Drawings 21489-362 and 181-101.
The room temperature of the TSC will be controlled by a variable air volume (VAV) system.
During the warmer periods of the year, cooling will be provided by mechanical or outside air cooling delivered by the air handling and conditioning unit.
When heating becomes necessary, a steam heating coil in the system will heat the supply air.
The charcoal system of the VAV will be put into operation manually when required.
In this case, the system will be operat-ing in a full recirculation mode.
r~ '<- 6 0
In the battery room, UPS room, and diesel room, separate fans and heaters shall be controlled thermostatically.
This facility is nearly complete and will be available for occupancy as the TSC in the near future.
