A combination steam separator shut-down cooler of the
conventional centrifugal-gravity type or of the fine mesh demister type is
used in each steam line between the reactor and orifices to provide dry
steam to the orifice. Care must be taken on the orifice or nozzle design
so that moisture does not cause instability and/or a faulty signal.
10. Water Flow Measurements
The total forced-circulation water flow is measured by
means of a venturi section located in the main reactor inlet line. Addi-
tional venturis are placed in the by-pass circuit and water cooler outlet
lines to measure these flows.
E. Secondary Coolant System
The use of a pressurized shell, water-cooled heat exchanger
and condenser system for disposal of reactor heat entails the incorporation
of a secondary forced-feed cooling water system. Demineralized water at
70F from a 1500-gpm water treating system will be supplied to the shell
side of the primary system water coolers and steam condensers by standard
boiler feed pumps in response to a standard liquid level controller. The
coolant will be allowed to boil for maximum heat absorption. Steam pres-
sure will be maintained by temperature-controlled, back pressure regula-
tors which discharge directly to the primary system steam disposal stack.
A standard type carbon steel boiler feed pump capable of
delivering approximately 800 gpm at 1600-ft TDH will be used. One pump
is required for the water coolers and one pump for the steam condensers..
These pumps are located in the Auxiliary Equipment Area.
A standard carbon steel piping system is satisfactory for
all of the secondary system.
F. Auxiliary Systems
In addition to the primary system, certain auxiliary systems
are needed for plant operation. These are the following:
