6. Turbine and By-Pass Simulator Flow Control
The turbine-simulator and by-pass simulator flow-control
valves are used to control reactor pressure or to simulate the turbine and
by-pass control on a direct-cycle boiling reactor system. The positions
of the four--turbine-simulator flow-control valves are adjusted in response
to constant or variable signals from the Jack Board (see Section G-7) in
such a way that smooth continuous control of flow is obtained over the en-
tire control range. -
7. Parameter Control Jack Board
Although ARBOR is primarily an experimental facility,
extensive use of automatic system control is necessary. Many of the pri-
mary variables will be controlled by one or more signals. Also, it will be
necessary in some experiments to change the control point of these vari-
ables according to some simple linear or oscillatory function. In order to
accomplish this, a Jack Board is provided. The signals from the required
temperature, pressure, and flow measurements pass through suitable ampli-
fiers and then to the Jack Board. At least three outlets for each signal are
provided. The necessary recording controllers have their input and set
point terminals at the board.
The following signals will require terminals at the Jack
a. Reactor pressure
b. Total steam flow
c. Turbine-simulator steam flow
d. Turbine-simulator by-pass steam flow
e. Feed-water flow rate
f. Total circulating water flow rate
g. Circulating water reactor inlet subcooling
h. Central control rod position
i . Reactor neutron flux.
The Jack Board will also be equipped to send information
to the controllers associated with the operation of the following:
a. Control rods
b. Turbine simulator and steam by-pass throttle valves
c. Water coolers
d. Forced-circulation flow and temperature-control
