ther electronic or electrical equipment.22 2. The reviewer verifies the adequacy of any plant features needed to alert personnel in high noise environments to use the communications systems as well as any plant features needed to shield communications from high noise environments. The reviewer also verifies the adequacy of any special equipment facilitating communications with personnel using protective equipment (e.g. respirators, underwater diving equipment).23 3. In cases where design bases and/or design criteria for independence between specific communications systems are proposed, the reviewer verifies the adequacy of proposed measures assuring that such systems will be implemented in accordance with the design criteria.24 4. Where wireless communications systems are proposed, the reviewer verifies that the applicant has addressed the following items: 25 a. A frequency allocation plan has been established such that there will be an adequate number of communications channels with no interference between channels/systems.26 b. Adequate coverage will exist to facilitate needed communications with plant and offsite personnel.27 c. Communications equipment to be used will be compatible with the electromagnetic interference (EMI) and radio frequency interference (RFI) design measures taken for the design and/or qualification of plant electronic, electrical, and computer equipment such that there will be no interference between wireless communications systems and other plant equipment. The applicant's consideration of the potential for interference should be based upon definition of the worst-case electromagnetic emissions from the communications equipment, including the type, magnitude, frequency content, and locations. The applicant should consider all potential uses of the communications equipment including maintenance activities.28 d. The communications system will be protected from the EMI/RFI effects of other plant equipment to the extent that clear
