.. _section-5.5:

Steam Generator
---------------

In addition to the simple table look-up steam generator model described
in :numref:`section-5.4.5`, SAS4A/SASSYS‑1 contains a detailed steam generator
model. The simple table look-up model is intended for cases in which the
steam generator behavior has little impact on the results of a
transient. The detailed model is intended for cases in which changes in
the steam generator heat removal rate and/or gravity head have a
significant impact on the results. Also, the detailed steam generator is
required when the balance of plant model is used. The detailed steam
generator model is described in :numref:`Chapter %s<section-7>`.
