Docket No. 50-334 Duquesne Light Company ATTih Mr. C. N. Dunn Vice President Operations Division 435 Sixth Avenue Pittsburgt:, Pennsylvania 15219 Gentlemen:
In accordance with our plans as described in our May 22, 1979 letter to you, the first of two direct and dedicated telephorie lines was recently in-stalled in your facility.
This line is part of what has been designated the Off Premise Extension (0PX) network, an automatic ringing system that is designed to facilitate immediate notifications to the NRC of significant incidents, and to provide continuous and uninterrupted coamunication of oper '
ational informe.6 ion between your facility, the NRC Operations Center in Beaicsda, Maryland, and ths Regional Office during the course of such inci-c'ents.
We have been testing the OPX network on a daily basis for tt.a past several welks, and plan to continue on this schedule until confidence 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 copy of the test procedure is ct uvided as an enclosure to this letter for your information.
The OPX network is not to be used for routiac communications with 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 require notification within cqe hour of the time a reactor is not in a centrolled 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.
Wr 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 (55-4) network, a dial-up syrtem - not automatic ringing, whi h is intended to be used during an incident to provide continuous ard uninterr ated communication between your facility, the NRC Operations Center, and tr a Regional Office regarding radiological and environ-mental matters.
You will be contacted soon regarding the installation of this second line, 27 p3, g
