Discussed topics on current reactor production fuels include: uranium core production data, uranium specifications, induction heat treating, fuel performance, residual stress measurements, AlSi process development, thoria program, and self-support program. The N-reactor fuels production is discussed. And concerning N-Reactor fuels development, process development and irradiation experience are discussed.

The objective of this supplement to Production Test IP-550-I is to include the K reactors in the program for routinely monitoring graphite oxidation rates. This supplement does not initiate a new program; it continues one which has been in existence for some time. Oxidation of the reactor graphite weakens its structural capacity. At some degree of oxidation, sufficient loss of strength will occur to significantly affect the ability to maintain and operate the reactors. For this reason it is necessary to control and to monitor the rates of oxidation in realtor. It is difficult to accomplish the latter in a truly representative fashion. A number of methods of obtaining information on this subject must be used; one of these is to expose small samples to the reactor atmosphere under operating conditions and then determine the average rate at which the samples have changed weight. This method has been employed in one fashion or the other for some time. Until June, 1962, the program was authorized by Production Test 105-532-E; from June, 1962, until January 26, 1964, the program was authorized by PITA IP-20-I{sup 4} at the K reactors.

From introduction: This is the final report on uranium carbide studies sponsored by the United States Atomic Energy Commission and performed by United Nuclear Corporation at its New Haven Research Laboratories during the period from May 1959 to January 1964. The work was part of the Commission's Fuel Cycle Development Program aimed at lowering the cost of nuclear power by improving fuel cycle technology. At the inception of this program in 1959, some work was in progress on uranium carbide. Little was known of making a satisfactory fuel in quantity or of how it would perform either in-pile or out-of-pile. The United Nuclear program was designed with no specific reactor in mind and was aimed at furnishing information over a broad spectrum.

Diffusion of beryllium-7 through polycrystalline unirradiated specimens of BeO was studied as a preliminary step to a study of diffusion in irradiated material. Beryllium-7 was deposited on one end of cylindrical specimens by exchange and adsorption from aqueous solution. The depth of penetration perpendicular to the surfaces of deposition was determined after annealing the specimens at pre-determined conditions. A simple lapping device of high precision was developed to determine penetration depths. For the polycrystalline cold-pressed and sintered BeO studied, the diffusion behavior between 1150 and 1800 deg C is described by the empirical relation: D = 2.49 x 10/sup -3/ exp -- (62.5 x 10/sup 3//RT) cm/sup 2//sec. A diffusion model is proposed based on vacancy migration which suggests identical activation energies for diffusion in both a and c directions in single crystals and predicts an activation energy of the correct order oi magnitude. Furthermore, the model p dicts that the frequency factor in the direction pexpendicular to the c axis should be about 50% higher than that parallel to the c axis. (auth)

A method is presented for designing a two-layer pressure vessel wherein contact between the layers is produced by controlled yielding of the inner vessel by internal pressure. The amount of prestress depends upon the dimensions of the vessel, the properties of the material of construction, and the prestressing pressure. The method takes into account the actual stress-strain curve of the material and satisfies the rules of plastic flow with work hardening. (auth)
