EXPERIMENTAL REACTIVITY EVALUATION OF THE ADVANCED TEST REACTOR CRITICAL EXPERIMENT
Technical Report
·
OSTI ID:4754871
The reactivity of the Advanced Test Reactor Critical Experimert (ATRCE) was evaluated with the core in the reference condition. Control cylinders were calibrated using determinations of positive reactor periods interpreted by the in- hour equation. The pulsed neutron technique was used to measure subcritical reactivities. Described are the reactivity evaluations for the hafnium neck shim rods. the outer shim control cylinders, and the borated Mylar tape used in the core region. The results of perturbation measurement of the reactivity coefficient of U/sup 235/ are included. (H.D.R.)
