APR 2 41980 Docket Nos. 50-317 50-318 Baltimore Gas and Electric Company ATTN: Mr. A. E. Lundvall, Jr.
Vice President, Supply P. O. Box 1475 Baltimore, Maryland 21203 Gentlemen:
A new telephone system has been installed at your site called the Health Physics Network (HPN). It is part of a system that includes all nuclear power plants, the NRC Operations Center, and the NRC Regional Offices. It is intended for use during emergencies and will function as the dedicated line between your health physics personnel and health physics personnel at the NRC Operations Center in Bethesda, Maryland and the NRC Regional Office.
In the event of a site emergency, the NRC will activate the HPN. You are still expected to use the Emergency Notification System (ENS) hotline for reporting emergencies. Comercial lines should be used if the ENS does not work. The HPN is a restricted network and should not be used by nongovernment employees at any time unless used by you to report a significant event when both the ENS and comercial telephone lines are out of service.
Lengthy consideration was given to the most efficient number and location of extensions for the ENS and HPN at each site. It was determined that, at the typical site, the ENS should have extensions -in the control room, shift supervisor's office, near site emergency operations facility (E0F) and alternate EOF, resident inspector's office, and the on-site technical support center.
Similarly, the HPN should have extensions where the HP and environmental staff would gather.
This is generally in the HP office, E0F and alternate E0F, and the resident inspector's office. Your individual locations may vary in accordance with your specific emergency plans.
Although each site has unique needs, a proliferation of extensions on the system could work to the disadvantage of the system. Requests for additional extensions will be closely examined and in some cases, new extensions may have to be installed at the expense of another existing extension.
