Edward L. Jordan, Director Division of Emergency Preparedness and Engineering Response U.S. Nuclear Regulatory Commission FROM:
Assistant Associate Director Office of Natural and Technological Hazards
SUBJECT:
Prompt Alert aM Notification Systems at the Pilgrim and Indian Point Commercial Nuclear Power Reactor Sites This is in response to your memorandum of March 25, 1983, in which you advised the Federal Emergency Management Agency (FEMA) of the concerns of Region I of the U.S. Nuclear Regulatory Commission (NRC) that the fixed sirens currently installed at the Pilgrim and Indian Point sites will not assure adequate coverage of the population at risk. These concerns are based on a June 19, 1982, offsite siren test by the Boston Edison Company for the Pilgrim Nuclear Power Station and the joint program of the Power Authority State of New York and Consolidated Edison to enhance their system. The following is a brief status report of offsite Alert and Notifi-cation ( A & N) systems in the vicinity of these plants:
Pilgrim Nuclear Power Station Boston Edison has reported to FEMA Region I that certain improvements have been made to the A & N system at the Pilgrim Nuclear Power Station that, according to the utility, meet the alert signal standards in Appendix 3 of NUREG-0654/ FEMA-REP-1, Rev. 1.
However, FEMA Region I states that all parties c.oncerned with the approval of the A & N system understand that FEMA cannot confirm this report until it finalizes its own verification methodology. Boston Edison reports that the following improvements have been made to the Pilgrim A & N system:
- completion of a computer modeling analysis for the optimal placement of sirens in the Plymouth area
- purchase cf six sirens to be installed in conformance with the modeling anaylsis
- current testing for adequacy of the revised siren system by Boston Edison 8308030374 830718 PDR ADOCK 05000003 F

.
- the utility requested a decision by the Massachusetts Civil Defense Agency for a broadcast frequency for tone alerts in addition Boston Edison has provided for an electronically secure siren activation system to avoid past problems of chance soundings of the sirens.
q Indian Point Nuclear Power Station The State of New York Radiological Emergency Group reports that the utilities (Consolidated Edison and the Power Authority State of New York) continue to install new sirens, and move the locations of existing sirens around the Indian Point site in an attempt to enhance the system. Eighty-eight sirens were originally installed with the number of sirens now approaching one-hunured and fifty, based on information available at this time. The opera-bility of the system during the March 9,1983, activation met the criteria of GM 18.
However, formal evaluation of the system against Appenaix 3 criteria will be scheduled in the future based on finalization of FEMA's,
" Standard Review Guide for the Evaluation of Alert and Notification Systems for Nuclear Power Plants".
