The design of the Fort St. Vrain steam generators

Assessments of advanced reactor heat supply to high temperature industrial unit operations: Heat Engines and Heat Pumps

“…The steam was then routed back to the Nuclear Steam Supply System (NSSS), i.e., it was exhausted to the single stage turbines of the helium circulators where it provided the motive force for rotation of the circulator compressors. Then, the steam was reheated to 540.5 °C in the upper (reheater) section of each SG module, before being directed back to the LP stages of the turbine generator [68]. After being condensed into water, it then flowed to condensate pumps, a demineralizer, a bank of heaters and a deaerating heater, then through the main feed pumps (where it was boosted in pressure to be able to enter the SGs) and finally through another set of heaters before restarting the whole cycle.…”
