This report records the progress made in the critical experiments for the Super-Critical Water Reactor up to mid 1954 when the program was severly curtailed by the shift in emphasis to the Reflector Moderated Reactor. In this sense it is an interim report on largely unfinished work and cannot present firm conclusions and comparisons with theory or calculations. The measurements which have been made were probably influenced by the non-uniform loading of the assembly, an expedient to achieve criticality at near design conditions, and are not, therefore, entirely amenable to interpretation. The value of the critical mass in a uniformly loaded core is 10.8 +- 0.5 kg U-235.
