IBR-2 reactor physical start-up. Measurement of neutron leakage spectrum
Description
The results of measuring the IBR-2 leakage neutron spectrum are presented. The measurements of spectrum have been carried out on the surface of the moderator (5 cm H2O) by means of activation detectors and 8 m far from moderator using a Bonner spectrometer. Comparison of experimental results with calculation data is given. It is found that on the surface of moderator the flux density of thermal neutrons with E < Esub(cd) equals 3x106 n/cm s Wt. From the measured neutron spectrum the absorbed and equivalent dose rates have been calculated. 8 m far from moderator the equivalent dose rate equals 50 mrem/h Wt
