SUBJECT:
COST ESTIMATE FROM COMMONWEALTH EDIS0N COMPANY FOR THE INSTALLATION
,,e OF ADDITIONAL CIRCUITRY AT THE BYRON NUCLEAR POWER PLANT'S EOF
. BUILDING AND PERMISSION TO USE SITE PROPERTY FOR CONTINGENCY TELECOMMUNICATIONS Reference is made to a comunication survey which was conducted at the Byron facili.ty by an NRC contractor representative on December 12, 1984. Based upon 4
this survey, NRC Region III is-initiating arrangements for the installation of contingency telecomunication equipment at the Byron site.
These arrangements consist of obtaining Comonwealth Edison Company's cost estimate to install additional telephone circuits in the Byron E0F and-formalized permission to install a temporary antenna during emergencies, or.as described below. The circuits and antenna location are essential elements of y
-our emergency telecomunications plan for the Byron site.
It should be noted that, with the exception of the equipment installation described below, comunications equipment will only be installed at any of the comunications sites in the event of an actual emergency or NRC participation drill, and will be removed imediately at the termination of the emergency or drill.
We are seeking Comonwealth Edison Company's estimate for labor and material to accomplish the following tasks:
1.-
Install a 7/8 inch foam RF transmission cable on the Met Tower located on the site. ' Cable should extend from the 200 foot level to a level accessible from the ground. Terminate upper end of the cable with a female N connector and the lower end with a male UHF connector. Both ends of the cable should be labeled for NRC Emergency Use Only and be housed in a weatherproof container to protect it from the elements.
2.
Install two WE-742 Terminal Blocks; one located in the NRC area in the E0F, the other outside of the E0F at or near the base of the microwave tower. The terminal ~ block at or near the base of the microwave tower should be labeled for NRC Emergency Use Only and be housed in a weatherproof container to protect it from the elements.
3.
Install two DC control pairs (voice quality circuits) from the EOF terminal block'to the base of the microwave tower terminal block. The wire for the control circuits should be at least equal in quality and size 4h 8609120074 860904 lI PDR ADOCK 05000454 l

Make available, during an emergency, the top of the E0F microwave tower, 170 foot level, for the installation of NRC radio systems.
Following receipt of your estimate, NRC Region III will issue the necessary purchase order. Work should not commence prior to receipt of the purchase order.
If you should have any questions regarding the above, please feel free to contact either Ruth LaFreniere (312) 790-5577 or Linda Kers (312) 790-5711 of my staff.
Enclosed for your information are the frequencies that the NRC equipment may use at this site. We appreciate your assistance in this matter.
