This report presents the results of a laboratory effort which was undertaken to determine mechanical properties of salt from Lyons, Kansas. Another goal of the experimental work was to define testing procedures, calibrations and data reduction during the process of generating strength data. Mechanical properties such as modulus of deformation and principal strain ratio were incorporated into simulations of Project Salt Vault using finite element methods. Deformational behavior of Lyons salt subjected to constant stress levels for extended periods of time was also evaluated in this experimental effort and compared to results determined for salt from other locations. Strength data and empirical relationships of strain as a function of time, stress and temperature were reduced for application to finite element analyses.

The design requirements, subsystem characteristics, environmental requirements, and cost and performance evaluation techniques are defined for the HTLF Large Solar Power System. The system is described as consisting of an array of linear focusing heliostats focusing on tower-mounted linear receivers. Heat transfer is by water/steam, and sensible heat storage is in oil/rock.

A rapid method is presented for calculating transport in a network of one-dimensional flow paths or ''pipes''. The method defines a Green's function for each flow path and prescribes a method of combining these Green's functions to produce an overall Green's function for the flow path network. A unique feature of the method is the use of the Laplace transform of these Green's functions to carry out most of the calculations.

The possible operating points of air/water and helium/water steam generators are parametrically presented. Calculation procedures and a sample computer program listing are provided. Multiple saturated steam conditions are shown to be attainable with the same gas inlet and exit temperatures. Design considerations of heat transfer surface area and pumping requirements are also discussed.

As the Nuclear Regulatory Commission has not yet issued a format guide for the preparation of an environmental impact statement for radioactive waste repositories, Rockwell Hanford operations has developed an annotated outline which will serve as the basis for the environmental evaluation activities until replaced by an appropriate NRC regulatory guide. According to the outline, the applicant should summarize the major environmental effects that are expected to occur during the construction, operation, and terminal isolation phases of the radioactive material repository. Compare these environmental effects with the possible effect of continued use of interim storage facilities. Unless unforeseen environmental effects become apparent, the summary should be a positive statement indicating that the short-term environmental effects are outweighed by the long-term benefits of the repository.

This report presents three different analytical solutions to approximate the surface uplift of a heated repository.
