d. Forced-Circulation and Reactor Feed-Water Pumps
The forced-circulation and reactor feed-water pumps
will be designed and their elevations relative to the reactor vessel and de-
aerating-hotwell specified by the Laboratory in collaboration with the pump
manufacturer(s). The Architect-Engineer shall be responsible for design
of the foundations, interconnecting piping, power supply, and control of
units. The method of mounting the pumps must be studied very carefully
to accommodate thrusts resulting from thermal expansion effects in the
large diameter suction and discharge piping.
It will be necessary to investigate thoroughly the
variation in feed-water pump requirements between Step II and Step III.
Steps I and II operation may permit use of a standard carbon steel boiler
feed pump, with a nickel-plated lining. Exact requirements for this unit can
only be determined after a detailed evaluation of all operating conditions.
Tentative design requirements for the pumps are given
for information in Appendix C of this report.
The de-aerating-hotwell is required for Step III. It
consists of a horizontal cylindrical tank designed for 2500 psi at 695F, with
approximately a 4000-gal water capacity. This vessel will be designed in
accordance with standard de-aerator practice as far as possible and in ac-
cordance with the ASME Code for Unfired Pressure Vessels (Section VIII).
The use of high-strength steels for construction of the hotwell shall be ex-
plored. A stainless steel liner is required.
The following nozzle connections are required on the
Condensate from condensers.
Water column (top and bottom) for level and pressure
Steam injection (estimated at 40,000 lb/hr) for main-
taining hotwell temperature.
Bleed to de-aeration system.
Water from primary water make-up system.
Reactor feed-water pump suction.
Return from feed-water pump back-pressure by-pass.
Here’s what’s next.
