SRE CRITICALITY FOR URANIUM-CARBIDE FUEL

Technical Report ·
OSTI ID:4240013

The critical mass for the third SRE fuel loading using 5.85% enriched uranium carbide fuel in a 7 rod cluster 5.5 ft long was calculated for a wet (180 deg C) clean, hot (425 deg C) clean, and hot (425 deg C) poisoned cores. An excess reactivity of 3.5% above hot-poisoned was provided for. A reactor power of 20 Mw and UC density of 13.63 g/cm/sup 3/ were assumed. (W.D.M.)
