Abstract
RELAP5/MOD2 simulations of post-dryout heat transfer in a 7 m long, 1.5 cm diameter heated tube are reported. The Biasi critical heat flux correlation is shown to be inadequate for predicting the experimental dryout. RELAP5 accurately predicted the measured temperatures downstream of the dryout once it was forced to predict dryout at the experimentally measured location.
