Abstract: 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.

Abstract: A radiometric analyzer for measuring characteristics of a material by radiation comprises a plurality of systems in which each consists of a radiation source and a radiation detector which are the same in number as the number of elements of the molecule of the material and a linear calibration circuit having inverse response characteristics (calibration curve) of the respective systems of detectors, whereby the measurement is carried out by a four fundamental rules operation of the mutual outputs of said detector system obtained through said linear calibration circuit. One typical embodiment is a radiometric analyzer for hydrocarbons which measures the density of heavy oil, the sulfur content and the calorific value by three detector systems which include a .gamma.-ray source (E.sub..gamma. > 50 KeV), a soft X-ray source (Ex .apprxeq. 20 Kev), and a neutron ray source.
