for technical specifications are covered in SRP Chapter 16.0. An important area to be reviewed is the remote or local control stations that are required by GDC 19 for the safe shutdown of the plant in case the main control room becomes uninhabitable. Plant designs should provide for control stations in locations removed from the main control room that may be used for manual control and alignment operations needed to achieve and maintain a hot shutdown and subsequently to be able to achieve'a cold shutdown. Equipment required for safe shutdown should be operable from local control panels. Access to these local control panels should be under strict administrative controls. Communications between the local control panels/stations should be provided. The design of these control stations should provide appropriate. readouts so that the operator can monitor the status of the shutdown. Typical readouts are steam generator level, steam generator pressure, pressurizer pressure, pressurizer level, reactor coolant temperature, and auxiliary feed- water flow. The remote control stations and the equipment used to maintain safe shutdown should be designed to accommodate a single failure.* Equipment located at these stations which is required for safe shutdown should be capable of operat- ing independently (without interaction) of the equipment in the main control room. The design should be such that a single failure will not prevent the capability. for affecting safe shutdown from the remote control stations. The remote control stations should be capable.of accommodating expected plant response following'a reactor trip including protective system actions which could occur as a result of plant cooldown. The remote control station equip- ment should be designed to the same standards as the corresponding equipment in the main control room. Control transfer devices should be located remote from the main control room and their use should initiate an alarm in the control room. An
