An IBM 7090 FORTRAN program was written for the preliminary design and cost estimation of unfired pressure vessels with or without a jacket. Both vessel and jacket designs conform to the 1959 ASME Boiler and Pressure Vessel Code, Section VIII, Unfired Pressure Vessels. Vessels and jackets from 5 in. pipe through 84 in. o.d. and 1/4 in. through 1 1/2 in. in metal thickness may be designed by this program as written. Total vessel cost is the sum of metal and fabrication costs, each on a weight basis. (auth)

The initial experimental program to study the transient heating of uranium carbide fuel in TREAT is outlined. Preliminary analyses are presented for the behavior of an HNPF prototype UC fuel slug during power bursts in the TREAT reactor. The analysis and evaluation conducted, center around the proposed utilization of the existing GE capsule, and indicate that this equipment will be suitable for the initial uranium carbide experiments with minor modification. A survey is presented and found not to be significantly different from the GE-UO/ sub 2/ experiments. A planning schedule for the program is shown, and in addition, recommendations for additional studies which should be conducted are presented. (auth)
