NUCLEAR MERCHANT SHIP REACTOR PROJECT QUARTERLY TECHNICAL REPORT FOR OCTOBER-DECEMBER 1957

Additional minor details of the propulsion system were modified during this period. A revised arrangement of the secondary shielding now includes a forward vestibule between the containment vessel and shield for the location of external reactor system components, particularly for the replacement of ion exchangers. Minor modiflcations of the containment cupola to house the control rod drives were confirmed. The basic design of most reactor auxiliary systems is complete. Only the waste collection and drain system, the control panel design, the radiation monitoring system, and the refueling system require further basic design work. The control rod effectiveness of boron--stainless steel rods with stainless steel fuel element cans was evaluated. As a result, the range of consideration of burnable poisons and soluble poisons likely to be required was more firmly established, and confirmation of exaet values required awaits only operation of the critical experiment. Arrangements were made to construct a smallscale model of the containment vessel and its internal components to verify erection procedures and clearances between equipment for maintenance. Further studies were made on the optimization of the primary and secondary shielding in preparation for conferences on secondary shielding design with the newly selected shipbuilder. Modifications to the reactor control system were developed to provide maneuvering rates cornparable with other merchant ships; the incorporation of these modifications is yet to be negotiated with the AEC. The design of the buffer seals was developed to the point where buffer charge pumps could be sized and, their specifications issued. (For preceding period see BAW- 1023.) (auth)
