Thermal Analysis of Mounting Plate and Instrument Holder in Upper Core Support Structure for LOFT Core III

摘要

The maximum temperature drop that could occur across the mounting plate or instrument holder is about 9 exp 0 F. This is based on conservative data and assumptions. Gamma heating was estimated from calculations for 55 MW operation; the value used was 0.015 Watts/gram of metal. The mounting plate is the restriction orifice on top of the upper end box on the center fuel assembly. The instrument holder is bolted to the top of this plate. Only steady state operation is considered. (ERA citation 05:000973)
