The irradiation schedule for the rabbit capsules to be inserted in WTR was established. A detailed review of various types of both top-. and bottom- mounted, upward- and downward-scramming control rod drive mechanisms was conducted. Procurement activities on the components for the critical facility proceeded at an accelerated pace. The Zircaloy-to-stalnless steel transition joint was moved to a point higher on the pressure tube so that none of the stainless steel portion of the joint extends into the reflector region. The transitions and U-bend baffle connections with the pressure tube and U-bend were modified. Hydraulic testing of nine experimental orifice plates was begin in Loop E. Calculations confirmed that the exit enthalpies in the fuel assembly flow channels for a 19 rod cluster arranged in a hexagonal lattice are less than when arranged in a circular lattice.
