20555 Subj ect: Toledo Edison's (TE) Participation in the Emergency Response Data System Gentlemen:
Toledo Edissa has reviewed the Emergency Response Data System (ERDS) implemen'.ation questionnaire that was forwarded by Mr. John R. Jolicoeur of Office for Analysis.and Evaluation of Operational Data. Toledo Edison is available to participate in the ERDS Project.
A copy of tha completed "ERDS Communications Description and Survey Questionnaire" for the Davis-Besse Nuclear Power Station is attached for Nuclear Regulatory Commission (NRC) review. The " Pressurized Water Reactor (PVR) Data Point Library Reference Files" are being compiled and are expected to be completed within sixty days.
The Data Point Library Reference Files vill be available for discussion / evaluation during a site visit by the NRC ERDS Project Team.
If you have any questions regarding the ERDS Project for the Davis-Besse Nuclear Power Station, contact Mr. R. V. Schrauder, Nuclear Licensing Manager, at (419) 249-2366.
Very truly yours, KLB/dlm Attachment ec P. H. Byron, DB-1 NRC Senior Resident Inspector A. B. Davis, Regional Administrator, NRC Region III E. L. Jordan, Analysis and Evaluation of Operational Data q[

Page 1 ERDS COMMUNICATIONS DESCRIPTION AND SURVEY QUESTIONNAIRE The following is a questionnaire pertaining to the Nuclear Regulatory Commission's (NRC) Emergency Response Data System (ERDS).
It consists of a series of cuestions concerning plant I/0-points, software protocols, data formats, transmission frequencies, and other plant computer specific information to De used in the ERDS computer database files.
Also, included here are descriptions and examples of data streams that the NRC is exoecting
'to see transmitted over the cmnnunication line.
l The purpose of collecting this data is to oevelop a olant specific catabase that will be retrievea into the ERDS once the system is activated by a i
l utility.
't will also be used' to oesign'and imolement ERDS software that can rece1ve tne utility's cata transmission.
In essence, this information will orovice tne basis for building a profile of the plant in tne ERDS datacase.
~
In some cases, the I/O point data may be distributed over several comcuters.
The ERDS considers this situation a multi-feeoer site and section IV must be filleo out for each feeder.

.Page 3-II.- ERDS COMMUNICATIONS DESCRIPTION A.
Hardware The following hardware will be supplied:
-for a single feeder site:
Codex 2234 modem.V.22 2400 bps, asynchronous, autodialing, auto answer, error correcting, using the AT command
- set, for a multiple feeder site:
Codex 6015 multiplexer, Codex.2260 modem - V.32 9600 bps, asynchronous, autodialing, auto answer, error correcting, using the AT command set.
B.
Software
- i. Data Transmission Site will initiate a link request in ASCII using:
a.
-three character site designator
-the work LINK
-local site time and date in the format MM/DD/YY/HH:MM:SS.
~
b.
ERDS will respond in ASCII with:
-three character site designator
-the word ACCEPTED or DENIED.
I c.
Upon being accepted, the plant begins transmission of data at a fifteen second rate. The data string consists of:
header that identifies the site and date and time
-data packet sequenced with point identifier, value, and quality tag
-trailer containing the checksum value of the data packet.

Data format
.Two delimiters have been identified as follows:
-field delimiter (*)
-Data Set, delimiter (\\)
Link request. will be in ASCII as described in II.B.i.a. with each field a.
separated by a field delimiter and the request terminated with a data set delimiter.
Example, pal
- LINK *01/12/89/11:48:50\\.
b.
ERDS response will be in ASCII as described in'II.B.i.b. with each field separated by a field delimiter and the response terminated with a
. data set delimiter.
Example, pal
- ACCEPTED \\.
c.
Data stream will be in ASCII and will consist of three parts, header, data.. and trailer, as described in II.B.i.e. with each field separated by a field delimiter and each of the three parts separated by a data set delimiter.
- Example, Header:
pal *01/12/89/11:50:30\\
Data:
B21CP004*-0.1234E+00*3*.....(for each parameter)\\
= Trailer:
56000\\.
d.
The following quality tags will be accepted by the ERDS:
-Good
=0 value is within range tolerance for discreet points, or input points are within tolerance for composed,,oints.
-Off-Scan
-1 point is currently out-of-service.
-Suspect
-2 value is not bad yet should not be considered good. This quality will occur primarily on composed values, when enough of the inputs are good to make the calculation yet a bad quality on other inputs may make the result questionable.
