This Interim Report summarizes the findings of our first twenty in-depth interviews in the Advanced Nuclear Reactor Public Opinion Project. We interviewed 6 industry trade association officials, 3 industry attorneys, 6 environmentalists/nuclear critics, 3 state officials, and 3 independent analysts. In addition, we have had numerous shorter discussions with various individuals concerned about nuclear power. The report is organized into the four categories proposed at our April, 1991, Advisory Group meeting: safety, cost-benefit analysis, science education, and communications. Within each category, some change of focus from that of the Advisory Group has been required, to reflect the findings of our interviews. This report limits itself to describing our findings. An accompanying memo draws some tentative conclusions.

The relation between the parameters of a differential equation and corresponding discrete maps are becoming increasingly important in the study of nonlinear dynamical systems. Maps are well adopted for numerical computation and several universal properties of them are known. Therefore some perturbation methods have been proposed to deduce them for physical systems, which can be modeled by an ordinary differential equation (ODE) with a small nonlinearity. A new iterative, rigorous algebraic method for the calculation of the coefficients of a Taylor expansion of a stroboscopic map from ODE's with not necessarily small nonlinearities is presented. It is shown analytically that most of the coefficients are small for a small integration time and grow slowly in the course of time if the flow vector field of the ODE is polynomial and if the ODE has fixed point in the origin. Approximations of different orders respectively of the rest term are investigated for several nonlinear systems. 31 refs., 16 figs.

The argon excluder is designed to reduce the media density of the dead space between the internal modules of the end calorimeters and the concave convex head to less than that of argon. The design of the excluder includes a thin circular stainless steel plate welded to the inner side of the convex pressure vessel head at a radius of 26 and 15/16 inches. It is estimated that this plate will experience a pressure differential of approximately 40 pounds per square inch. A inner foam core is incorporated into the design of the excluder as structural support. This engineering note outlines the compression data for the foam used in the north end calorimeter argon excluder. Four test samples of approximately the same dimensions were cut and machined from large blocks of the poured foam. Two of these test samples were then subjected to varying compression magnitudes until failure. For this test failure was taken to mean plastic yielding or the point at which deformation increases without a corresponding increase in loading. The third sample was subjected to a constant compressive stress for an extended period of time, to identify any 'creeping' effects. Finally, the fourth sample was cooled to cryogenic …

An Environmental Protection Agency (EPA) approved sampling and analysis protocol was developed and executed to verify atmospheric emissions compliance for the new Savannah River Site (SRS) F/H area Effluent Treatment Facility. Sampling equipment was fabricated, installed, and tested at stack monitoring points for filtrable particulate radionuclides, radioactive iodine, and tritium. The only detectable anthropogenic radionuclides released from Effluent Treatment Facility stacks during monitoring were iodine-129 and tritium oxide. This paper only examines the collection and analysis of tritium oxide.

The material covered in this report is divided into two parts: further cyclization experiments on 1,4-diethyl-2-[(2'- methoxyphenyl)thio]benzene and its sulfone both by chemical and photochemical means, and progress toward synthesis of modified target molecule, 9-isopropyl-4-methoxy-6-methyldibenzo-thiophene. 8 refs, figs.
