A preliminary equipment specification for the design, development, and test of an upward scramming controlrod drive mechanism was prepared. An order was placed for the fabrication of CVTR critical exoeriment fuel elements. Task 5.00, irradiation experiments, was revised to include additional exposure irradiation tests on tensile, impact, and creep sample specimens of Zircaloy. Corrosion tests were initiated on samples of several possible CVTR control-rod materials and also on various samples of Zircaloy-2 brazed specimens. Construction was stanted on a thermal cycling facility to test gasketed fittings. An order was placed for the manufacture of seal welding and cutting equipment. This equipment will be used to test the feasibility of repeated welding and cutting of prototype seal weld designs. A study of the AECL work on magnesia- insulated thermal baffles was initiated. Design and layout work were initiated toward applying such a concept to CVTR. Partial analysis of the data obtained from Loop E tests on the fuel assembly showed that the spacer wire pitch has a significant effect on the pressure drop. A study was completed on the design of a gas sweep system that will eliminate the need for seals between the U-tubes and the top neutron shield. (auth)
