Critical experiments have been performed with low-enriched UO/sub 2/ arrays simulating underwater pin storage of spent pressurized water reactor fuel. Pin storage refers to a storage concept in which fuel assemblies are dismantled and the individual fuel pins from several assemblies are tightly packed into specially designed cannisters. Each critical configuration is sufficiently described and documented to permit the use of these data for validating criticality calculational methods according to ANSI Standard N16.9-1975. The reactivity of each benchmark core was calculated using the AMPX-KENO IV package. The results of these analyses are also presented.
