III. DESIGN REQUIREMENTS
In the preceding description of the facility the discussion has been
presented on the basis that the plant would be constructed in its entirety.
However, because of the problems of fund availability it will probably be
necessary to construct the plant in several steps, each of which would
constitute an operating unit capable of fulfilling a portion of the flexibility
requirements for the entire plant. The steps selected are as follows:
Step I - Direct-Cycle Forced and Natural Circulation
In this step the water coolers, steam condensers, secondary coolant
equipment, steam separators, the hotwell and its auxiliaries, the reactor
feed-water pump as described, the primary water make-up system, and the
reactor water cleanup system are omitted. No heat removal from forced
circulation water is possible, and the steam generated in the reactor is
discharged directly to the stack through back pressure-regulating valves.
The 1500-gpm water treatment plant and a less expensive feed-water pump
are used to supply make-up water to the reactor.
Step II - Dual Cycle
The water coolers and necessary auxiliaries are added to permit
heat removal from the forced circulation water.
Step III - Indirect Cycle and Heavy Water Operation
The steam condensers, hotwell and associated systems, reactor
water cleanup and primary water make-up systems are added to convert
the plant to its complete form as described.
The discussion of design requirements in this section will take into
account the effort required for Steps I, II, and III. A more detailed state-
ment as to the Architect-Engineer's duties regarding stepwise construction
will be found in Section IV, Scope of Work and Division of Effort.
The Architect-Engineer shall prepare complete architectural
and design drawings and specifications for the Main Building, control room,
and Auxiliary Equipment Area buildings, condenser and water cooler areas,
electrical substation, and appurtenant structures. This set of drawings will
represent the plant as completed at the end of Step III. Additional drawings
will be prepared to show alterations and deviations to facilitate construction
of Steps I, II, and III.
