Abstract
Defines requirements for additional instrumentation to measure coolant parameters, which are of interest when abnormal conditions arise with either one or two phases of coolant or with gas included in the reactor vessel. The information obtained on coolant conditions assists the operator to decide on actions needed to maintain adequate core cooling.
