==Dear Mr. Denton:==

River Bend Station - Unit 1 Docket No. 50-458 Enclosed for your review are revisions to the Final Safety Analysis Report (FSAR) sections which discuss the use of portable radios.                These revisions will be included in a future FSAR amendment.
Sincerely,

                            .                  RBS FSAR without the involvement of offsite facilities. Such phones are    located    in    the administration building, control building, containment outside the drywell, turbine building, radwaste building,      shops,   auxiliary building, switchgear rooms, fuel building, and other locations as required.
9.5.2.2.1.4    Hand-Held Portable Radio System A   completely independent radio system is provided          for security purposes, as discussed in Section 13.6.
There is one UHF onsite channel for plant operation.
Hand-held portable radios are available for use during normal and emergency conditions. The radio system operates on UHF band frequencies in the 450 MHz range.         The base station for plant operations is capable, via fixed repeater, of communicating with hand-held portable radiostancuncre      mui"~

9.5.2.2.1.5    Intra-Site Communications
()              The GSU telephone system, the page-party system, and the portable intercom system provide means for communications between the Unit 1 and 2 main centrol rooms and other locations throughout the station.
9.5.2.2.1.6   Cable and Circuit Rcuting All   communication cables are eitbt cf the coaxial type (as for microwave) or are composed of twisted pairs with short lays. They are isolated by distance, shielding or conduit enclosure from power cables, or any source of line noise which could affect their signal content. They are also isolated from any low signal level cables which they might affect.
All communication systems wiring in general plant areas is routed in rigid metal conduit, underground           duct,    or electrical metallic tubing (EMT).
9.5.2.2.2   Plant-to-offsite Communications The plant-to-offsite ccmmunications consist of the following separate, independent, and diverse        systems adaptable   to in plant and offsite locations:

    )   13.3.6.2   Communications Systems 7 e details of the onsite emergency communications network a e shown on Fig. 13.3-19.      Reliable communications links exist between various areas of the plant, emergency response icilities, and offsite organizations. These systems          have sufficient     redundancy      and/or    diversity    to     ensure availability of communications during emergencies.
13.3.6.2.1   Site Communications
: 1. Page-Party /Public Address System      (PP/PA)     -
The Page-Party /Public Address System may be accessed from    numerous handset stations throughout the plant. It is possible to select the use of public address loudspeakers or any of five channels for communication with any of the          other     handset stations. The system is also used as an evacuation and fire alarm signal.      This alarm signal takes automatic priority over any other signal on the paging channel while the party channel remains unaffected.
: 2. Private Branch Exchange System - The Private Branch Exchange System is an extension of                          "
the    GSU A                telephone system, having communications with cne
~%g$              another, as well as, direct offsite access.        Phones will be placed throughout the plan- including the Main Control Room, TSC, Radiation Protection Area, OSC,   EOF,  and other areas as necessary. A set of phones will be available in the TSC and EOF for use by   NRC    personnel    during    emergency response operations. See Fig. 13.3-17.
: 3. Hand-Held Portable Radio System - There is a UHF          g radio system for plant operations and another, completely     independent     system    for    security operations. These hand-held portable radios are available for emergency use. These radio systems are capable of       communicating    with     hand-held  6 portable radios fin andJ" around the plant. These radios are battery powered and not dependent on any electrical system     of .the plant. Portable radios will be available in the EOF for use by offsite radiation survey teams.
: 4. Paging System    -
A paging system will be used for notifying the RBS emergency organization personnel           l16 during off-normal hours. This system uses regular            e dial telephone service to access the system and s
