System requirements for cooling the shield within the vacuum vessel for the core test reactor are analyzed. The total heat to be removed by the coolant system is < 22,700 Btu/hr, with an additional 4600 Btu/hr to be removed by the 2-inch thick steel plate below the shield. This latter heat is radiated to the walls of the vacuum chamber where the heat is removed by the cooling coils wrapped around the outside of the chamber. The maximum temperature of the concrete in the shield can be kept below 200°F if the shield plug walls are kept below 160°F. The walls of the two "donut" shaped shield segments, which are cooled by the water from the shield and vessel cooling system, should operate below 95°F. The walls of the center plug, which are cooled with nitrogen, should operate below 100°F.

A request is made for 50,000 photographs of 60 GeV/c {pi}{sup -} and 50,000 photographs of 200 GeV/c {pi}{sup -} in the Argonne 30 inch hydrogen bubble chamber at NAL. Reasons are given explaining how good physics can be done with this chamber. This experiment is a natural extension of the work of the group and will be of great usefulness in preparing for experiments with the CERN II accelerator.

The synthesis of nonracemic yields of hexa-, hepta-, octa-, and nonhelicene with circular light was observed, and the structural and wavelength dependence of the induced optical yields was examined. The results obtained, together with a detailed consideration of the mechanism of helicene synthesis from the parent diarylolefins, indicate that the induced optical activity is due to selective reaction of enantiomeric conformations of the parent cis diarylolefins by circular light.

Fatty acids have a reversible inhibitory effect on respiration and on photosynthetic action. They investigated the influence of octanoic acid on the photosynthetic bacteria Rhodopseudomonas spheroids R-26. From the spectroscopic data they conclude that a less efficient energy transfer and decoupling of the light harvesting pigment system from the energy converting reaction center is responsible for the inhibitory effect.

Driver fuel cladding, process tube and graphite temperatures were experimentally simulated with an electrically heated test assembly to establish the rate of radiation heat transfer from the fuel to the process tube foilowing a loss-of-coolant incident in the N-Reactor. This information is necessary as supporting data and verification for the analytical description of such an incident. The available results of the first three of a total of six experiments are presented. These results are suitable to allow DUN to evaluate, modify, and calibrate the MELT Code which is used to analytically describe the loss-of- coolant incident in N-Reactor. (auth)
