A transition program, eliminating most of the wet chemical techniques for the preparation of cell feed and replacing these with a high temperature chlorination process, was begun. Crushing tests on a Fitz mill were initiated and tentative conclusions are that this type of equipment as superior to a combination of jaw and roll crushing. Small scale chlorination experiments indicate the feasibility of pelletizing ThOCO/sub 3/ for feed to a eontinuous hightemperature chlorinator. (D.E.B.)

A systems analysis is made of a class of nuclear-propelled rockets in combination with chemical boosters. Various missions are considered including the delivery of 5000-lb payload 5500 nautical miles, the placement of a satellite in an orbit about the earth and the delivery of a payload to escape velocity. The reactors considered are of the heterogeneous type utilizing graphite fuel elements in a matrix of Be or hydrogenous moderator. Liquid hydrogen and ammonia are considered as propellants. Graphical results are presented which show the characteristics and performance of the nuclear rockets as the design parameters are varied. It should be emphasized that this report is not in any sense intended as a handbook of rocket parameters; it is intended only as a guide for determining areas of interest.
