To date, two 200% double-ended cold leg break experiments have been completed in the LOFT Power Ascension Test Series. LOCE L2-3 was conducted with maximum linear heat generation rate, core fluid temperature rise (..delta..T), and system pressure characteristic of the normal operating conditions of a commercial pressurized water reactor (PWR). The thermal behavior of the core in both experiments was dominated by a self-induced cooling mechanism which occurred soon after experiment initiation. The dominance of this phenomena versus current licensing calculation restrictions raises the question of the prototypicality of the LOFT results. The ensuing discussion summarizes both an analysis of the most significant experimental results and a prototypic study of the LOFT results relative to ZION, a commercial PWR. ZION is similar to TROJAN, the commercial PWR to which LOFT was scaled.
