A prototype on-stream analyzer was developed for the analysis of boron added to solutions of U/sup 235/ for criticality control in the reprocessing of reactor fuels. The method used is determination of thermal neutron absorption. The analyzer, or neutron absorptiometer, is a neutron source surrounding a unit in which the solution being analyzed flows around a BF/sub 3/ counter at rates more than 50 gal/min. In order to slow the neutrons down to thermal energy, a paraffin moderator is used in conjunction with the source. Calibration curves are given for water and 60% HNO/sub 3/, and analysis for boron can be carried out in the range of 0 to 2 g/l. The instrumentation necessary for recording the counting rate is described. (D.L.C.)
