SUBJECT:
DOCKET NO. 50-302 During the past four years, NRC has had a contract witt, the Boise Interagency Fire Center (BIFC) to establish / evaluate emergency communications.
These evaluations include plans for minimizing the time required for the development of NRC radio equipment and/or BIFC radio equipment as well as augmenting response personnel in the event of an emergency or during an exercise.
BIFC personnel have conducted site Radio Frequency Interference (RFI),
Electromagnetic Interference (EMI) and radio equipment placement surveys at your site. These surveys provide guidance on the installation and use of HF and VHF radio communications during an emergency condition at a reactor site.
BIFC Survey findings and recommendations for your site are enclosed. Region II requests your assistance in estimating the cost of implementing these recommendations.
Based on the cost estimates gathered, Region II may request licensee installation of these systems in the near future.
Your cooperation would be greatly appreciated.
If you have any questions regarding this matter or need additional information, please contact Mr. W. Stansberry of our staff at (404) 331-5248.
Sincerely, Original Signed by Luis A. Reyes Luis A. Reyes, Acting Director Division of Reactor Projects

ENCLOSURE EMERGENCY COMMUNICATION SYSTEM FOR CRYSTAL RIVER NRC Regional and National Radio Support Cache Equipment 1.
At the Repeater Site Unit I and 2 Control Complex, establish a direct cable path from the stair and elevator shaft structure, on the roof, to the radio room located two flights of stairs below. Install 1/2 inch foam lleliax with the lower or radio room end terminated in a UHF male connector. Install a Phelps Dodge PD 1107 antenna on the roof of the stair and elevator shaft structure.
Connect the upper end of the Heliax cable to the antenna.
2.
At the EOF, a direct cable path should be established from the NRC area inside the EOF to a point outside the top of the building and 1/2 inch foam Heliax installed. The Heliax should be terminated at the NRC area with a UHF male connector. Install a Phelps Dodge PD 1107 antenna with the coaxial skirt a minimum of six inches above the roof parapet. Connect the upper end of the Heliax cable to the antenna.
3.
At the EOF, run one, two pair shielded cable from the NRC room in the E0F to a point at the base of the antenna. The cable should be terminated inside the NRC room and at the roof with WE 742 wire junctions.
These circuits should be permanently reserved for NRC use and the terminations so marked.
The NRC should supply the WE 742 wire junctions to the licensee to insure system compatibility.
The frequencies and power levels that the NRC equipment may use at each site are as follows:
Repeater Site TSC, E0F, and Portables 169.109 20 watt 169.100 6 watts 165.6625 165.6625 The frequencies and power levels that the NRC equipment may use at each site are as follows:
