Abstract :
Neutron flux detectors of the counting type, as designed for thermal reactors may provide a capability for some fast reactor control safety and surveillance applications. Shortterm tests in environments of up to 106 R/hr gamma and to 950??F served to characterize the operational limits for the sensors. Fast pulse-shaping techniques (20 to 50 nanoseconds) improved the gamma tolerance capability of sensors having collection times of 50 to 200 nanoseconds.
