The results of a study are presented which provided additional experimental-loop irradiation space for the AECDRD testing program. It was a premise that the experiments allocated to this reactor were those which could not be accommodated in the MTR, ETR, or in existing commercial test reactors. To accomplish the design objectives called for a reactor producing perturbed neutron fluxes exceeding 1O/sup 15/ thermal n/cm/sup 2/-sec and 1.5 x 1O/sup 15/ epithermal n/cm/sup 2/-sec. To accommodate the experimental samples, the reactor fuel core is four feet long in the direction of experimental loops. This is twice the length of the MTR core and a third longer than the ETR core. The vertical arrangement of reactor and experiments permits the use of loops penetrating the top cap of the reactor vessel running straight and vertically through the reactor core. The design offers a high degree of accessibility of the exterior portions of the experiments and offers very convenient handling and discharge of experiments. Since the loops are to be integrated into the reactor design and the in-pile portions installed before reactor start-up, it is felt that many of the problems encountered in MTR and ETR experience will cease to exist.

Reactivity changes, flux variations, and detector-response variations for ZPR-III fast critical assemblies, due to variations in heterogeneities caused by various intradrawer configurations of fuel and diluent plates and deviations of reactivities from ideal homogeneous cores, are calculated as reflective boundary slab cells using the DSN code. For these cells the calculated multiplication constants, for a given assembly plate configuration, by N = 4,8, and 16 approximations successively increase such that the eigen-values obtainbale at N = 16 are still generally far from the limiting values at large N. This aspect makes for uncertainty, especially if differences in k/sub eff/ values from homogeneous are desired. (auth)

A curve relating the output signal from the thin-walled ionization chambers of the cosmotron to the number of protons passing through the chambers for fast r-f turnoff is presented. (D.C.W.)

The charged particle optics of symmetric and asymmetric spectrometers was developed, taking into account the effects of fringing fields. Formulas are given for: the image of point and extended sources, and their resolution and transmission. The suppression of ghost peaks arising from multiloop trajectories was studied. Methods and tables for the calculation of instruments are given. A comparison was made between various instruments already constructed, and some general considerations concerning the choice of design parameters are presented. The correction (for fringing field effects) of sector profiles of instruments already constructed was analyzed, and formulas are given which permit the calculation of modifications of the profiles necessary to insure good focusing with high transmission. Tables include: general trajectory functions; profile curves; and dispersion and transmission functions for symmetrical instruments. (auth)

Results of studies with ZPR-IH Assembly 29, a mockup of a typical, dilute UO/sub 2-/-fueled fast reactor, are reported. The assembly consisted of a 454-liter cylindrical core, blanketed with depleted uranium, with a critical mass of 42l kg U/sup 235/. Experimnents included measurements of fission rates, material reactivity worths, and Rossi alpha. The results of multigroup calculations using the present Argonne cross-section sets are presented, and discrepancies between experimental results and calculations are discussed. (auth)
