The optimum nuclear radial power peaking factor as a function of radial zoning is investigated for large carbide LMFBRs of the 5000 MW(t) class. Four different fuel volume fractions are considered. The two radial zones are characterized by different plutonium enrichments. The dependence of the optimum power peaking factor on the volume and enrichment ratios of outer to inner core is investigated for static conditions and for burn cycles corresponding to first core loading. A simple phenomenological model is used to determine the functional dependence of the optimum enrichment split on the ratio of inner to outer core volume.

Progress during the first quarter of the contractual effort is described. The work performed relates (a) to ribbon growth by a capillary action shaping technique, (b) to ribbon characterization, and (c) to economic evaluation and computer-aided simulation of ribbon growth. Actual progress includes growth of 12-mm and 25-mm-wide ribbon with individual lengths ranging from 0.12 to 1.06 meters. The growth of silicon tubes of 6-mm diameter, 1-mm wall thickness, and more than 100-cm length was also accomplished. The ''growth rate'' problem of melt-grown ribbon-shaped crystals was addressed. An expression for maximum growth rate of cylindrical (Czochralski geometry) crystals and ribbon-shaped crystals was derived. Some representative values at 7.5-cm diameter or width are 45 cm/hr or 2000 cm/sup 3//hr for a cylindrical Czochralski-grown crystal and 625 cm/hr or 95 cm/sup 3//hr for a 0.02-cm-thick ribbon.

Results are reported from a hybrid experiment designed to search for backwards produced I = 2 exotic meson resonances by investigating the backward scattering reactions: ..pi../sup +/ + p ..-->.. in (forward) + ..pi../sup +/..pi../sup +/, ..pi../sup +/..pi../sup +/..pi../sup +/..pi../sup -/, ..pi../sup +/..pi../sup +/..pi../sup +/..pi../sup +/..pi../sup -/..pi../sup -/, and p anti p..pi../sup +/..pi../sup +/ at an incident pion momentum of 8.4 GeV/c. The SLAC 15'' rapid cycling bubble chamber, operating at 20 cycles per second, was triggered by detecting fast forward neutrons in an optical spark chamber and scintillation counter array downstream. Following two-component duality arguments, Jacob and Weyers and Rosner have suggested backward scattering processes as a favored mode for exotic meson resonance production. Upper limits of the order of one microbarn are reported for the production of narrow exotic meson resonances with masses less than or equal to 3 GeV and which could decay into even G-parity states: ..pi../sup +/..pi../sup +/, ..pi../sup +/..pi../sup +/..pi../sup +/..pi../sup -/, ..pi../sup +/..pi../sup +/..pi../sup +/..pi../sup +/..pi../sup -/..pi../sup -/, and p anti p..pi../sup +/..pi../sup +/. The mass resolution in the above channels varied from 5 to 30 MeV over the mass range for the most restrictive sample of events. The statistical significance of the …

A method for data communication between PDP-8/L and NOVA 1220 computer-based multichannel analyzer systems is described. The method is implemented by modification of each system's operating program with appropriate I/O subroutines and by installation of a minor amount of hardware logic to a NOVA general purpose interface board. The method provides for high speed transfer of gamma energy analysis data between a Nuclear Data Corporation 50/50 system and a Tracor-Northern Corporation 660 system. (auth)
