d' June 22, 1979 Docket No. EC 271 Vemont Yankee Nuclear Power Corporation ATTN:
Mr. Robert H. Grace Licensing Engineer 20 Turnpike Road Westborcugh, Massachusetts 01581 Gentlemen:
In accordance with 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 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 Cente" in Bethesda, Maryland, and the Regional Office during the course of such in-i-dents.
We have been testing the OPX network on a daily '
!e for the past several weeks, and plan to continue on this schedule until coatice ice in the reli-ability 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 1py 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 ccmmunications with the NF.
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 require notification within one hour of the time a reactor is not in a controlled or expected condition of operation.
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 row 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 socn regarding the installation of this second line.
