A proposal has been made to achieve a greater overall total production from the N-reactor through multi-product operation. Apparently, this can be achieved by producing tritium along with plutonium. Tritium production technology is presently based on low temperature and pressure water environments at SRP using targets which contain Al-Li alloy. Past experience has shown that the transport of tritium and lithium and the swelling which can result from helium agglomeration are all strong functions of temperature. Since operation of target elements at N-reactor conditions constitutes an extrapolation from available operating experience, a R&D effort is required in order to delineate and resolve any problems associated with target element operation in the N-reactor. This proposed irradiation test is a significant part of this R&D effort.

Desirable characteristics of pulsed magnets used as ejectors or inflectors for large accelerators can be obtained by loading the magnet with distributed capacitance or by using a capacitor in shunt with the load. Comparable field build-up tlmes are available with either arrangement. The lumped magnet system offers greater simplicity. (D.C.W.)

The problem of coupled radiation and convection to a medium in slug flow between infinite, parallel plates was formulated in terms of discrete fluxes. Steady state, uniform heat input, and gray boundaries were assumed. The effects of absorption, emission, scattering, and flow were taken into account. For the general case where all these effects are present, it was necessary to approximate the fourth order temperature term by a truncated Taylor series. This approximation was not necessary for the special case where conductivity of the medium is negligible. Approximate, analytical solutions in closed-form for profiles of temperature, radiant fluxes, and heat fluxes were obtained for both the special case and the general case. Sample results are presented, showing the effects of convection, absolute temperature, absorption coefficient, scattering coefficient, and wall emissivities. The two cases of equal wall temperatures and unequal wall temperatures were both examined. It was found that for a fluid with the thermal conductivity of air, radiation can account for 60 to 95% of total heat transfer in the temperature range of 900 to 2800 deg R. It was also found that for some situations, the scattering phenomenon can have a much greater effect on heat transfer than the …

The complex response of polymers to radiation necessitates knowledge of the radiation resistance and of the effects of radiation type, energy, and intensity on the resistance. A brief discussion is given of the types of radiation and their interactions with materials, and the techniques for measuring the amount of energy absorbed in a material from the radiation field are surveyed. Present-day knowledge of how various parameters and properties of the specimen affect its response to radiation is discussed. Some of the problems peculiar to exposing a sample to radiation are described. Finally, a survey is presented of the status of standard test methods for irradiated polymers. (D.L.C.)
