IN-CORE NEUTRON FLUX DISTRIBUTION MEASUREMENTS
The simple method of in-core neutron flux distribution measurements was developed using copper wires activated in the measured area. The activity distribution along the wire was measured continuously, or the wire was cut into the small pieces and their activities were measured. A 2{pi} proportional flow-type counter, G-M counter, and scintillation counter were investigated as the counting devices. The G-M counter gave the best signal-to-background counts ratio and a good efficiency. The G-M window counter and the scintillation counter with NaI(Tl) welltype crystal were used for activity measurements of wire pieces. The scintillation counter efficiency was better by a factor of 5 than that of the G-M counter. This method can be used for neutron flux greater than 10/sup 5/ n/cm/sup 2/sec. (auth)
