mong principal response organizations to emergency personnel and to the public. b. Two emergency planning functions have been defined for this planning standard: (1) Systems are established for prompt communication among principal emergency response organizations. (2) Systems are established for prompt communication to emergency response personnel. c. Section IV.E.9 of Appendix E to 10 CFR Part 50 provides supporting requirements. Informing criteria appear in Section II.F of NUREG-0654 and the licensee’s emergency plan. The following are examples of changes to the licensee’s emergency plan that could require prior NRC approval: (1) A change could require prior NRC approval if it would reduce the availability and reliability of primary and backup communications systems used to (1) notify and activate State and local emergency response centers or (2) enable communications between the licensee’s ERFs and with ORO and Federal emergency operating centers in accordance with the emergency plan (e.g., replacing dedicated private lines with a public exchange service). (2) A change to ERO callout procedures or hardware could require prior NRC approval if it would delay ERO notification such that the augmentation times in the emergency plan can no longer be achieved. (3) A change could require prior NRC approval if it adjusts the frequency of communication testing or maintenance to a level that the site’s experience with system reliability does not support. An example of this type of change would be a scheduled maintenance interval that is greater than the observed mean time between failures of the equipment or a reduction in the availability of backup capabilities. d. A change to replace the phone talker relay of inter-facility communications with digital data communication would generally not require prior NRC approval provided that the replacement is equivalent to, or better than, the current system with regard to timeliness, accuracy, and reliability (the
