Connecticut Yankee Atomic Power Company
ATTN:
Mr. E. J. Mroczka
Senior Vice President - Nuclear
Engineering and Operations Group
P. O. Box 270
Hartford, Connecticut 06141
Gentlemen:
Subject:
Inspection No. 50-213/85-08
We have received your letter dated June 9,1987, which details the present
status of your meteorological data transmission system and discusses your re-
evaluation of proposed long-term solutions to previously identified data
J
transmission problems.
Your proposal to utilize the Offsite Information System to provide back-up
meteorological data transmission capability appears to be an acceptable
alternative to your previous committment to install digital data displays and
a dedicated, real time data terminal.
Adequacy of these systems will be
examined during a future inspection of your Radiological Environmental
Monitoring program.
Your cooperation with us is appreciated.
Sincerely,
Crictual Sicnod B7: ,

Unresolved Item No. 50-213/85-08-04
I&E Inspection No. 50-213/85-08 (Reference 1) identified an
unresolved item (No
50-213/85-08-04) in regard to Connecticut
Yankee Atomic Power Company's ( C YAPCO ) inability to bring nete-
{
orological monitoring equipment within tolerance ranges specified
I
in calibration procedures.
A short term solution - utilizing
!
spare wires in the cable between the Meteorological Building and
1
the Control Room - was accomplished.
Reference (2) committed to
j
evaluate long term solutions.
Part one of the long term solution
involved installing a data terminal in the control room which
utilized a transmission path separate from that used for
previously installed equipment.
This was reported complete in
Reference (3) which also extended the date for part two -
replacing the analog recorders with digital data displays and
installing a dedicated, real time data terminal - to December 1,
1987.

The purpose of this letter is to inform you of the results of a
reevaluation which -CYAPCO has done on this issue. . The present
system performs well.
The information' received.in the control
room via the data terminal is accurate and reliable.
The analog
recorders function well and provide a backup to the terminal.
A
new plant process computer will be installed during the upcoming
refueling outage.
The Of fsite Information System (OFIS), which
permits access of plant process computer data by several remote
'ocations, will be operational approximately six. months following
l
.
the outage (about April 1988).
OFIS will be supplied with mete-
orological data.
Since this system would essentially duplicate
part two of the proposed long term solution, CYAPCO intends to
use OFIS in place of part two.
It should be noted that CYAPCO
considers the presently installed system to'be adequate in all
respects and the use of OFIS to transmit meteorological data to
be above and beyond that required.
Very truly yours,
CONNECTICUT YANKEE ATOMIC POWER COMPANY
