...s June 22, 1979 Docket No. 50-309 Maine. Yankee Atomic Power Company ATTN: Mr. Robert H. Groce Licensing Engineer 20 Turnpike Road Westborough, Massachusetts 01581 Gentlemen:
In accordance witn our plans as described in our May 22, 1979 letter to you, the first of two direct and dedicated telephone lines was recently in-stalled in your facility.
This line is part of what nas been designated the Off Premise Extension (OPX) network, an automatic ringing system that is desigaed to facilitate immediate notifications to the NRC of significant incit. ants, and to provide continuous and uninterrupted communication of oper-ational information between your facility, the NRC Operations Center in Bethesda, Maryland, and the Regional Office during the course of such inci-dents.
We have been testing the OPX network on a daily basis #or the past several weeks, and plan to continua nn this schedule until confideilce in the reli-ability of the net'.. ark has ean 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 with the NRC.
It shall be used enly 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, wnich recuire notification within one hour of the time a reactor is not in a controlled or expected condition of operati%.
In addition, the network shall be used where it is apparent that immediate NRC attention is necessary.
This may include some, but certainly not all, prompt notifications 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 incident to provide continuous and uninterrupted communication between your facility, the NRC Operations Center, and the Regional Office regarding radiological and environ-mental matters.
You will be contacted soon regarding the installation of this second line.
