Members in the wind-energy research, development, deployment, and production communities use computer codes for many things. They base important decisions on the results from the codes. It is important that the developers of these codes scrutinize them to assure an appropriate level for quality. The National Wind Technology Center (NWTC) and its subcontractors have developed many computer codes now in use in the United States and around the world. This document will present some guidelines for ensuring the quality of programs that are developed for the NWTC.

The growing awareness of the hazards of chemicals in the environment has resulted in the passing of the Toxic Substances Control Act (TSCA) on Oct. 11, 1976. This paper attempts to cover some of the salient features of Public Law 94-469, EPA's approach to implementation of its provisions, and some of a chemist's perceptions of TSCA's prospects of success.

The variety of applications, databases, and information technologies makes it difficult to locate and retrieve information or applications that are otherwise openly available. The promise of the World Wide Web was that it was a paradigm for organizing and distributing information. Under this project, we looked at how we could more tightly couple the Web with the UNIX operating system for exchanging information, connecting programs and data, and facilitating collaboration between people in a more natural way. Ease of secure access and the ability to have electronic dialogues on specific questions will become increasingly important as the pressure Increases for scientists and analysts to rapidly access diverse information to make informed judgments and initiate new lines of Investigation.

Screening criteria and specifications are recommended to aid in the evaluation of sites proposed for nuclear waste disposal in basalt and domed salt. The recommended new criteria proposed in this report are intended to supplement existing repository-related criteria for nuclear waste disposal. The existing criteria are contained in 10 CFR 60 sections which define siting criteria of the Nuclear Regulatory Commission (NRC), and ONWI 33(2) which defines siting criteria of the Office of Nuclear Waste Isolation (ONWI) for the Department of Energy. The specifications are conditions or parameter values that the authors recommend be applied in site acceptance evaluations. The siting concerns covered in this report include repository depth, host rock extent, seismic setting, structural and tectonic conditions, groundwater and rock geochemistry, volcanism, surface and subsurface hydrology, and socioeconomic issues, such as natural resources, land use, and population distribution.

Brief descriptions of research papers in radiobiology, biochemistry, metabolism, and biophysics published during 1979 are presented. The research was conducted by investigators in the Dept. of Radiation Biology and Biophysics. (ACR)
