Static and dynamic models with distributed and lumped parameters have been developed
for steam generators of water-moderated nuclear reactors (WMNRs).
It has been shown that the application of static models with lumped parameters may lead to incorrect
design solutions when constructing steam generators. It is stated that dynamic models with lumped
parameters have a low accuracy, especially in the case of the primary water temperature channel used
as a control action in the thermal load control system of the nuclear reactor.
