KING OF PRUSSIA, PENNSYLVANI A 19406 June 22, 1979 Docket No. 50-29 Yankee Atomic Electric Company ATT?h Mr. Robert H. Grace Licensing Engineer 20 Turnpike Road Westborough, Massc husetts 01581 Gentlemen:
In accordance with our plans as described in ou'- May 22, 1979 letter to you, the first of two direct and dedicated telephone lines was iecently in-stalled in your facility.
This line is part of what has been designated the Off Premise Extension (OPX) network, an automatic ringing system that is designed to facilitate immediate notifications to the NRC of significant incidents, and to provide continuous and uninterrupted communication of oper-ational information between your facility, the NRC Operations Center in Bethesda, Maryland, end the Regional Office during the course of such inci-dents.
We have an testing the OPX network on a daily basis for the past several 5 <.eks, and plan to continue on this schedule until confidence in the reli-
..bility of the network has been established and all problems have been elim-inated.
After that we will continue the tests but at a reduced frequency.
A copy of the test procedure is provided as an enclosure to this letter for your information.
The OPX network is not to be used for routine communications nth the NRC.
It shall be used only for those events requiring immediate notification as defined in 10 CFR 20.403(a), and in IE Bulletin Series Nos. 79-05, -06, and
-08, which re'uire notification with:a one hour of the time a reactor is not q
in a controlled or expected condition of operation.
In addition, the network shall be used where it is apparent that immediate NRC att tion is necessary.
This may include some, but certainly not all, prompt no+
ications now required.
We are now arranging for the installation of the second direct and dedi-cated line into your facility.
This line will be part of what has been desig-nated the Selective Signaling System (SS-4) network, a dial-up system - not automatic ringing, which is intended to be used during an inc.ident to provide continuous and uninterrupted communication between your facility, the NRC Operations Center, and tM Regional Office regarding radiologica' and environ-mental matters.
You will be contacted soon regarding the installation of this second line.

If you have any question; concerning these communications networks or any comments regarding their use, please contact Mr. Robert Carlson of this office at (215) 337-5280.
Sincerely,
