To investigate variable leakage and complex interactions of systems, a full-scale nuclear mockup of the HWCTR was constructed in the reactor tank of the Process Development Pile. In the initial experiments performed in the mockup a study was made of the proper strength for the boron poison in the driver assemblies and in the control rods to obtain the desired operating characteristics of the HWCTR. A variety of methods was used to obtain differential and integral worths of the control rods. A series of flux traverses and neutron current determinations at the pile boundaries was undertaken to determine the over-all neutron economy under various reactor conditions.
