called PHWRs. Design parameters of a typical commercial CANDU reactor are
given Appendix A.
Future sections address the processes that dictate reactor dynamics for all reactor
types, but the details of the reactor dynamics and control strategies are presented only
for those Generation II types developed and employed in North America (PWR,
BWR, and CANDU reactors). Potential advanced reactors are addressed, but in less
detail than currently operating reactors.
Other power reactor types were developed and deployed, but so far have never
enjoyed the widespread application of the Generation II reactors described above.
Gas-cooled reactors (GCRs) using carbon dioxide or helium coolant and graphite
moderator have been built and operated, mostly in Great Britain. These high temper-
ature gas-cooled reactors (HTGRs) deployed in Great Britain are referred to as the
advanced gas-cooled reactors (AGRs).
