(17) Water Cooler Liquid Level - Water cooler second-
ary side water level will be measured by a differential pressure controller.
This controller will operate the control valve in the secondary coolant feed-
water pump discharge line. Liquid level will be read on a multi-point
(18) Water Cooler Temperature and Pressure Control -
The differential temperature and pressure between the secondary coolant
steam on the shell side and the primary system water on the tube side of
the water cooler inlet shall be controlled by a variable range recording
pressure controller. This instrument will control operation of the second-
ary coolant steam release valve. The plant annunciator will be actuated by
individual readings at adjustable limits to indicate abnormal operation
Other methods of controlling water cooler oper-
ation shall be investigated.
(19) Forced-Circulation Water Flow - The signal from
the total forced-circulation flow tube (WF4) will be continuously recorded
on a square root circular chart flow recorder controller. This recorder
will be equipped with a low flow alarm contact for shut-down annunciator
actuation. This total flow signal will also go to the Jack Board. This
signal will control the forced circulation by-pass butterfly valve. Flows
through the by-pass orifices and the individual heat exchanger flow orifices
or venturi shall be individually read on a multi-point flow indicator and
used to check the main flow tube.
e. Auxiliary Systems
In general the instrumentation and control of auxiliary
systems will be as simple as possible. Selective indication in the control
room of most signals will be required, but only a few will require contin-
uous recording. In general, when a signal is listed in the following section
only selective indication is required. In cases where control or high and
low-limit alarm contacts are required, these functions are noted.
(1) Reactor Water Clean-up System (Step III)
(a) Temperatures at regenerative heat exchanger
inlet and discharge points, both sides.
(b) Temperatures at discharge of cooler - high-
~ temperature alarm contact to close valve in
return line to reactor and actuate plant an-
(c) Conductivity of water entering and leaving
