T. T. Martin letter to 3. F. Opeka, dated May 20,1935 Gentlemen:
Haddam Neck Plant inspection Report No. 50-213/85-03 Informational Letter in Regard to Unresolved item No. 213/85-08-04 During IE Inspection No. 50-213/85-08, your Mr. A. A. Weadock identified an unresolved item (No. 213/85-03-04) in regard to our inability to bring meteorological monitoring equipment 'within tolerance ranges specified in calibration procedures.
As pointed out in the inspection report, CYAPCO attributes this problem to inadequacies in some meteorological signal cable.
l between the Meteorological Building and Control Room.
Because of this problem, we committed to provide a short term solution and evaluate potential l
long term solutions considering the reoccurring nature associated with the underground meteorological signal cable. Again, as noted within your inspection report on March 31,1985, during a phone conversation we confirmed that a short term solution had been accomplished. This was done by utilizing spare cable within the cable run for meteorological signal transmission.
Once this switchover was completed, successfulinstrument calibration was attained.
In response to your second request to evaluate a long term solution, we have l
done so and are committed to the following action plan:
O A supplemental means of data transmission will be available vic use of an on-demand, dial-up data terminal which will be installed in the control room to obtain meteorological data from the mini-computer at l
the base of the tower, via a telephone line completely separate frorn the signal cable.
This terminal is scheduled to be operational by October 1,1935. The strip chart recorders will remain operative.

<.. n 2-0 The planned final solution to provide meteorological data access in the control room entails replacing the existing analog recorders with digital data displays and installing a dedicated, real time data terminal. This will continually display data from the mini-ccmputer at the base of the tower which will be transmitted via a telephone line.
i Because of the time required to procure and install the new devices, and consider appropriate backup schemes, an in-service date of October 11,1986 is targeted, if you should have any additional concerns, feel free to contact us.
Very truly yours, CONNECTICUT YANKEE ATOMIC POWER COMPANY S.T.D
