Author(s)
Anil Gurgen, Dagistan Sahin, James R. Whipple
Water cooled reactors experience reactivity changes when voids are present in the coolant. The fraction of coolant in the core diminutions in the event of boiling, and the reactivity feedback can either be positive due to reducing neutron absorption in the

RADIATION MONITORING SYSTEM UPGRADE FOR THE NBSR
