The limited supply of relatively long-half-life isotopes having a reasonably high power density and the low conversion efficiencies obtainable with thermoelectric devices have so far limited the power output of isotope-fueled sources of electric power to several tens of watts. In addition, the high cost of the available isotopes results in a very large expense for isotope-fueled generators producing several hundred watts. It appears that a small, minimumweight, conduction-cooled reactor is an attractive alternate to the isotope-fueled power supplies in the 200-w size range. The proposed reactor is a small, high-density fast core of U/sup 233/ surrounded by a beryllium reflector. This approach, generally speaking, gives a reactor that is more compact and of lighter weight than can be obtained with a moderated system having a softer neutron spectrum. In the reactor design, the path of heat flow is from the core to the inner reflector and then to the thermoelements in close contact with the inner reflector. The reject heat flowing from the thermoelement cold junctions enters the outer pontion of the reflector, which acts as the heat sink and conducts the reject heat to the large, circular, tapered-fin radiator which is attached to the reflector.

This report has two volumes, volume 1 contains the summary and detailed description of plant design, volume 2 contains a comprehensive nuclear evaluation of the reactor core.

This report includes the nuclear evaluation that has been conducted for the purpse of studying those problem areas which are expected to increase in severity as the core size is increased to produce 1000 MWE.

The effects of 1-hr anneals at 1000 and 1800 deg F on the mechanical properties of Type 347 stainless steel specimens taken from the ETR J-10 pressure tube after fastneutron (> 1 Mev) exposures of approximates 7.1 x 10/sup 21/ nvt were studied. The pressure tube operated at a maximum temperature of approximates 750 deg F in a stressed condition. Testing was done at 75 and 750 deg C. Uniform elongations were increased from approximates 1% in the as- irradiated material to 15 and 25%, respectively, by the 1000 and 1800 deg F anneals. The 1000 deg F annealing appeared to produce a better combination of mechanical properties. The microstructure of unirradiated, as-irradiated, and postirradiation-annealed specimens were very similar except for two specimens inadvertently heated above 1800 deg F during annealing. (auth)

An investigation was made to find a method of color coding the various jet orifices with different hole sizes to facilitate assembly of the NRX A-1 core. High temperature paints, ceramic paints, temperature indicating paints, and cements were investigated. Various degrees of success were obtained. No one type of paint was found which had excellent adherency after application and after being subjected to 1500°F for one-half hour, yet was available in many colors, was easy to apply and use, and had a very thin coat after drying. Some colors of high temperature paints will do as an alternate method to that of colored plastic caps presently planned.
