Abstract

This report contains a compilation of over 25,000 critical heat flux (CHF) data points obtained in water-cooled tubes that were used to derive the 2006 Groeneveld CHF lookup table. This compilation is based on 62 data sets that have been obtained during the past 60 years. This NUREG report describes the pertinent experimental details and possible concerns for these data sets. It also discusses the applicability and validity of the CHF lookup table to reactor conditions of interest and includes a graphical comparison of the ranges of conditions covered by these primary data and subsequently obtained supplementary data sets.
