CRITICAL MASS OF AN OMR CORE USING PLATE TYPE FUEL ELEMENTS
Technical Report
·
OSTI ID:4216997
The clean critical mass of a core using low enrichment U plate-type iuel elements in a six-inch lattice spacing and using Santowax R at 340 deg F as the moderator was experimentally determined. Criticality was attained with thirty- nine fuel elements, containing 3915 kg of U, present in the core, three shim rods withdrawn, and the fourth shim rod about 7/8 withdrawn. The interpolated clean critical mass was determined to be 3910 kg of U. (W.L.H.)
