provide extreme flexibility in control parameters. The control circuits for
related operations of equipment should be interlocked, insofar as possible,
to prevent improper sequence of operation due to human error.
In general, control of steam flow, water flow, steam pres-
sure, inlet subcooling, water level, condensate flow, etc., should be by
electric motor-operated controllers (except where fast response requires
air operation) mounted as close as possible to the device controlled. Signal
and set point information will be telemetered from the instrument to the
control room. Electrical transmission of signals shall be used in all cases
except where there are specific reasons for employing other means. Where
an instrument is directly connected to the primary system for measure- -
ments such as flow, etc., there must be no possibility for the instrument to
contaminate the primary system with undesirable materials under any con-
dition of operation, including any possible failures of the instrument.
The entire instrumentation and control system, with the
exception of nuclear detection instrumentation and control rod drives and
position indicators, shall be designed by the Architect-Engineer in close
cooperation with instrument and instrumentation system manufacturers and
with the Laboratory. Where control room space is required for Laboratory-
supplied items, such as the devices excepted above, the Architect-Engineer
shall provide such space as required and shall integrate these devices into
the general control room arrangement.
It should be emphasized that the general control schemes
indicated here are tentative and subject to change when more detailed de-
sign studies indicate that changes are desirable.
The Control Room Area in the Control Building will be ap-
proximately 20 ft x 50 ft in size and shall have a centrally located control
console containing the instrumentation and controls necessary for reactor
start-up and operation. The three walls in view of the reactor operator
when seated at the console will contain the various system recorders, in-
dicators and controls together with the central annunciator- and shut down
Recorded indication from the system will be displayed on
various strip and circular chart recorders as specified below. The panels
should be of standard width, with instruments mounted for convenient read-
ing. All recording instruments shall be equipped with large pointers or
scale indicators readable at a distance, and shall be mounted to afford full
view to the control console. It is desirable to have one company furnish
all instruments insofar as possible in order to obtain a uniform appearance
and to facilitate maintenance. Panels should be designed to enable complete
