DEFINITION

Classification: 376/207

WITH CONTROL OF REACTOR (E.G., CONTROL OF COOLANT FLOW):

(under the class definition) Subject matter for changing (including "shut down") or maintaining constant the fission reaction rate or power output of a nuclear fission reactor.

(1) Note. Detection of a reactor state is proper subject matter for this subclass provided it is in combination with a control means for the fission reactor.

(2) Note. For the structure of the subcombination control component which is an absorber, see this class (376), subclass 327.
