FIG. 10.11
A moving boundary model of OTSG [8].
The dynamics of these components are represented by using mass and energy
conservation Eqs. A complete description of the governing equations is given in
Refs. [6, 8] with associated plant parameters. Valve and pump models are not
included in this representation. For a complete representation of the BOP dynamics
it is necessary to include dynamic models of these components (and actuators).
10.10 Reactor system models
Chapter 12 addresses PWR dynamics. An appendix to Chapter 12 illustrates the for-
mulation of a complete PWR reactor system model using models described in
Chapter 3 for neutronics and this chapter for heat transfer. Another appendix (Appen-
dix K) addresses molten salt reactor dynamics. Appendix K provides an illustration
of the use of modeling techniques for a reactor with very different properties than
current commercial reactors.
