HRT Modified Pressurizer Design

“…Heat Load iCalculations .-. These design calculations are based,, in part, on .modifications of work done by F. C. Zapp (1). A heat transfer coeff icf ent for losses by radiati on can 'be expressed as:('(~ssuming the hot enclosed body is smd.1 in &ea a8 compared to the cooler enclosure and is convex throughout, and the enclosure is concave=-throughout) g = radiation heat transfer coefficient, ~/ h r ft2 OF :-, : ; .= emissivity of the hot surface ' .…”
