HEAT DISSIPATION FROM FUEL ASSEMBLIES OP LOW POWER HIGH FLUX REACTOR AFTER SHUT DOWN

摘要

Experiments using a mock Fuel Assembly channel 11.4 mm thick, approximately the size channel considered for the Low Power-high Flux Reactor, show that between 1270 and 1470 Btu/(sq ft)(hr) can be transferred by natural convection of air without exceeding the melting point of aluminum in the channel. Calculations show that an operating power level of about 1300 kw is permitted by this heat transfer capacity.
