CALIBRATION OF THE ACTIVE WELL COINCIDENCE COUNTER FOR CYLINDRICAL, HIGH ENRICHMENT URANIUM - ALUMINIUM FUEL ASSEMBLIES
The Active Well Coincident Counter has been calibrated for the verification of high enrichment uranium - aluminum, cylindrical fuel tubes and assemblies of the type used in the DR3 research reactor at Risoe, Denmark. A special polyethylene insert was used to hold and irradiate the fuel for a two-position measurement. For coincidence counting, a single calibration curve is adequate for the verification of tubes and assemblies with 45% and 93% enrichment. The counting statistics error for a 600-s coincidence measurement is about 1% for assemblies and about 3% for tubes. The positioning error is about 1%. Total neutron counting is also useful for the rapid intercomparison of tubes or assemblies; the counting statistics error for a 60-s totals measurement is about 0.6% for assemblies and 1.5% for tubes.?
