Tory II-C program: introduction and general description

Description: Declassified 26 Nov 1973.<><DSN>29:026171<ABS>The rotating fluidized bed reactor concept is outlined and its application to rocket propulsion discussed. Experimental results obtained indicate that minimum fluidization correlations commonly in use for 1-g beds can also be applied to multiple-g beds. It was found that for a low thrust system STA90,000N (20,000 lbf)! the fuel particle size and/or particle stress play a limiting role on performance. The superiority of /sup 233/U as a fuel for this type of rocket engine is clearly demonstrated in the analysis. The maximum thrust/weight ratio for a 90,000N thrust engine was found to be approximately 65N/kg. (19 references) (auth)

Engineering design of the Tory II-C nuclear ramjet reactor

Description: Declassified 27 Nov 1973. The Tory II-C nuclear ramjet reactor is the culmination of the Lawrence Radiation Laboratory's development efforts in the Pluto program from 1957 to 1964. Details of the design and assembly of the reactor are presented. Included are descriptions, criteria, analyses, and computations of the core components, axial and transverse reactor support systems, and reactor controls. In addition, a detailed description of the assembly of the reactor is profusely illustrated. Not included are discussions of reactor control actuators, electronic systems, etc. (auth)

Pluto fuel element fabrication at Lawrence Radiation Laboratory

Description: Declassified 26 Nov 1973. Development of an extrusion-based process for producing beryllia fuel elements for the Pluto nuciear powered ramjet is described. The goal was to extrude and fire hexagonal tubes to close dimensional tolerances without grinding. Sinterable beryllia powder was fueled by precipitating uranium and fuel additives from a single aqueous solution in which the beryllia had been slurried. After sintering, the fuel phase consisted of a phasestabilized solid solution of urania (UO/sub 2/) with yttria and zirconia. Principal operations consisted of slurrying and precipitation, filtration, drying and calcination, vehicle incorporation and mixing, extrusion, drying and vehicle burnout, and hydrogen sintering (including straightening). Directions for continued development toward the no grinding'' goal are pointed out. (auth)

Tory II-A: a nuclear ramjet test reactor

Description: Declassified 28 Nov 1973. The first test reactor in the Pluto program, leading to development of a nuclear ramjet engine, is called Tory II-A. While it is not an actual prototype engine, this reactor embodies a core design which is considered feasible for an engine, and operation of the reactor will provide a test of that core type as well as more generalized values in reactor design and testing. The design of Tory II-A and construction of the reactor and of its test facility are described. Operation of the Tory II-A core at a total power of 160 megawatts, with 800 pounds of air per second passing through the core and emerging at a temperature of 2000 deg F, is the central objective of the test program. All other reactor and facility components exist to support operation of the core, and preliminary steps in the test program itself will be directed primarily toward ensuring attalnment of full-power operation and collection of meaningful data on core behavior during that operation. The core, 3 feet in diameter and 41/2 feet long, will be composed of bundled ceramic tubes whose central holes will provide continuous air passages from end to end of the reactor. These tubes are to be composed of a homogeneous mixture of UO/sub 2/ fuel and BeO moderator, compacted and sintered to achieve high strength and density. (30 references) (auth)

Tory II-A reactor tests. Final report

Description: Declassified 26 Nov 1973. Tory II-A was the first reactor in a series which will lead to development of a nuclear-powered ramjet engine in the Pluto program. The core embodied a design which is believed to be useable in an actual engine. All parts external to the core were intended only to form a suitable test bed, and had no relation to flyable hardware. Test operations were conducted during the period December 1960--October 1961, On May 14, 1961, following several months spent in low-power measurements and facility shakedown, the reactor was brought to 50 MW power (1/3 design) and 2580 deg F core temperature (300 deg above design) for a period of about one minute. All systems operated properly, and no indication of any damage was obtained. After a period of facility alterations, to provide the capability of delivering test air at higher temperature and pressure, the reactor was run three times at power levels approaching or in excess of the design operating value of 160 MW. The second of these tests fully achieved design operating conditions, and the third substantially exceeded them in severity. Again no indications of failure were noted during operation. Disassembly of the reactor has confirmed that it maintained its structural integrity. In general confirmation of previous experimental data, thermal stress cracks were found in many fuel element walls. Fewer cracks than expected, however, were found in the hottest part of the core, indicating that considerable stress relief through creep must have occurred. Even among the elements which cracked, no instance was found in which an air flow passage was blocked. 18 references. (auth)

Mobile energy depot feasibility study: summary report

Description: Declassified 28 Aug 1973. Various methods of producing and using nuclear power for military land vehicles and other military equipment were investigated and evaluated. A nuclear-powered mobile energy depot (MED) would move with advancing armies and produce vehicle fuels from materials readily available in the field. This would make mechanized units independent of external fuel supplies for extended periods, and permit them to move quickly and easily to areas impossible for units that depend on the customary fuel supply lines. Many possible MED systems were evaluated on the basis of energy sources, fuel manufacturing (by both conventional and chemonuclear processes), fuel storage and transportation, and fuel utilization in both present-day internal-combustion engines and power units of the future (i.e., fuel cells). The applications of more than a dozen MED systems to vehicular propulsion were studied. (auth)
