摘要： A nuclear reactor output power meter for measuring the output of a nuclear reactor from the concentration signal of radioisotope .sup.16 N in a primary coolant loop, having a transient response correction circuit. This correction circuit includes an approximated normal distribution response filter. This filter has a group delay time substantially corresponding to a single circulation time necessary for the primary coolant loop of the nuclear reactor. This filter also has a rise time in the step response substantially corresponding to a spread in the rise time of the .sup.16 N concentration signal due to agitation occurring during the single circulation time.
