Reactor control and instrument center

1 Beactor Control and Instrument Center. The reactor control and instrument center is composed of an instrument room-and a contro1.room, respectively, on the second and third floors of the lean-to section on the west side of the Reactor Building. The control room, directly above the instrument room, is at the level of the reactor top with access thereto by a connecting walkway. A stairway connecting these rooms facilitates the maintenance of associated control and instrumentation devices. The partition walls of the reactor control room are formed of sectional metal construction, 

The services provided within the control and instrument. rooms are peculiar to the use of these rooms. For consistency of instrument performance, these rooms are air-conditioned for control of temperature and humidity. All lighting in the control room is by incandescent lamps, including a number of luminaries for general room illumination. Panel instrument illumination, is provided by internal instrument lights and flush-mounted ceiling spotlights Illumination in the instrument room is provided by fluorescent and incandescent lamps. 

The control room layout includes an instrument panel to accommodate the initial requirements for indicators, recorders, and annunciators with a number of spare and- partially utilized panel sections for future requirements.. This panel board, - facing in the direction of the reactor, is composed of eleven 4-ft-wide by 9 ft-high sections and extends the full length of the room with a rear access door at each end. Six panel sections, three at each end of the board, lie in a straight line. These two end panel groups are connected by the central panel sections which are arranged on a radius of approximaxely 7K ft to allow for the control console. 

The console in the control room mounts all devices for effecting manual control of the reactor control indicating devices, and some indicating instruments. Other reactor indicating instruments and recorders are located on the central panel sections immediately in front of the console, as indicated in Fig. 5.8.A.
