Dear Mr. O'Reilly:
By letter dated July 27, 1981, Carolina Power & Light Company (CP&L) described to you the prompt notification systems at both our Brunswick Steam Electric Plant and H. B. Robinson Steam Electric Plant.
CP&L stated that both systems would be fully implemented by September 30, 1981. By letters addressed to Mr. J. M. Hendrie, dated June 30, 1981, CP&L had requested' exemption from the requirements of Section IV.D.3 of Appendix E to 10CFR Part 50 by extending the completion date for the fromptnotificationsystemsfromJuly1,1981toSeptember 30, 1981.
CP&L has completed its original commitment to install by September 30, 1981 the Brunswick and Robinson prompt notification systems prt tously described. The thirteen sirens in the original prompt notification system design at Robinson and the nine sirens in the original design for Brunswick have been completely installed and field tested by radio activation from the county warning points for counties within each Emergency Planning Zone (EPZ). One siren at Robinson failed its radio activation test and will be resited to obtain improved radio reception of the control signal. When tested, the siren equipment performed according to the manufacturer's specifications with respect to sound level output. However, due to higher-than expected background l
noise levels and higher than expected dissipation, the maximum measured effective range of the sirens was only 1.5 miles. The projected range in the original design of the prompt notification system was 3.25 miles as discussed with the NRC/ FEMA Policy Committee on February 23, 1981.

As a result, the systems at both plants cover only thirty percent of each plant ten-mile EPZ.
In order to complete coverage of the ten-mile EPZ, Robinson will require 32 additional sirens and Brunswick will require 21. Fifty-three (53) Federal Signal Thunderbolt sirens have already been ordered.
CP&L is committed to installing and field testing-the additional ~ sirens as soon as possible. However, unforseen delays due to equipment or right-of-way precurement may be experienced.
In any case, CP&L will make every effort to install the additional sirens at both Robinson and Brunswick and field test the expanded prompt notification cystems by February 1,.1982.
CP&L will inform you should any delays be experienced that may hinder completion by ti.is date.
If you have any questions on this subject, please contact
,U our staff.
Yours very truly, f.
