LOFT emergency core coolant thermal analysis Class I review
The LOFT Emergency Core Coolant Piping Thermal Analysis was checked to insure that the calculations made would conservatively satisfy the requirements in the LOFT technical specifications. Some of the boundary conditions used have not been shown to be conservative and require review and possible re-analysis. One of the thermal models used could not be clearly related to a specific part of the piping geometry and requires further explanation. The remainder of the models, the use of the SIMIR code and the other boundary conditions appear conservative and reflect normal thermal analysis methodology and practice. However, the use of constant, rather than temperature varying, thermal properties for some materials may introduce a slight error in these analyses.

HGP-A wellhead generator proof-of-feasibility project
The HGP-A Wellhead Generator Proof-of-Feasibility Project consists of a nominal 3 Megawatt geothermal steam turbine electric power generating facility, the first geothermal power plant in Hawaii. The plant is being constructed as a research and development project to evaluate geothermal steam as a viable resource to be considered for larger commercial electric power generating stations in Hawaii. The project facilities include a turbine building, with a contiguous service area for plant operations and maintenance, visitor center, and the power plant equipment.

Primary system temperature limits and transient mitigation
Results of a study to determine the limiting temperature conditions in a large reactor system are presented. The study considers a sodium-cooled breeder reactor system having a loop-type primary system configuration. A temperature range of 930 to 1050/sup 0/F in reactor outlet temperature is covered. Significant findings were that the use of the materials for the 930/sup 0/F reference design, i.e., a core material of 20% cold-worked 316 stainless steel, a primary piping material of 316SS, and a steam generator material of unstabilized 2-1/4 Cr - 1 Mo resulted in limiting conditions in component performance at the higher temperatures. Means to circumvent these limits through the use of alternate materials, mitigation of thermal transients, and/or design changes are presented. The economic incentive to make some materials changes is also presented.

High-temperature industrial process heat: technology assessment and introduction rationale
Three specific topics of interest to DOE are addressed: to establish the significance and identify the role of high-temperature process heat in the nation's energy economy; to identify the role of solar thermal power in these high-temperature industrial applications in terms of possible markets and economic potential; and to recommend programmatic approaches for these solar thermal high-temperature process heat activities, including proposed content for initial Request for Proposals (RFPs) to accomplish such activities. The scope of the work required to accomplish these three purposes included the following: review of US industrial energy requirements, survey of current DOE low-temperature Agricultural and Industrial Process Heat Program, examination of high-temperature solar thermal electric systems already developed or under development by DOE and industry, and coordination with the high-energy user segments of industry (i.e., cement, chemical and petroleum) to find additional markets for some or all of the systems or components being developed in the DOE solar thermal electric program. Statistical data are presented identifying energy allocations to process heat and defining DOE's involvement. Three current fossil fuel process heat system examples are provided and the corresponding solar potential is identified.

Lawrence Livermore Laboratory x-ray calibration facility
An X-Ray Calibration and Standards Laboratory has been established at the Lawrence Livermore Laboratory to provide x-ray calibrations of various types of x-ray diagnostic equipment presently being utilized. This Laboratory is the outgrowth of many years of involvement in the development of x-ray generation and calibration equipment. X-ray calibrations in a steady state mode are available from 100 eV to 100 keV. Pulsed response and linearity studies as well as radiation damage studies can also be performed. A crystal fabrication, characterization and calibration facility is an integral part of the Laboratory. A general discussion of various equipment and capabilities within the Laboratory is presented.

Summary of climatic input for waste management site suitability criteria and state of progress
Because groundwater movement can have important effects on buried nuclear wastes, hydrologists need to know if future climatic changes will influence the accuracy of groundwater flow calculations. Groundwater recharge (and therefore groundwater flow) depends on surface water balance. (Surface water balance equals precipitation less losses to evaporation, runoff, and storage.) To develop input data for modeling future climatic effects, we have made the following simplifying assumptions: (1) Climate (and therefore water balance) will behave in the future very much as it has in the past. (2) Groundwater recharge responds linearly to precipitation. (3) Future long-term climatic changes can be classified into groups or regimes that are similar to those of the past. Our current research is aimed at providing input data to the Waste Management Program's site suitability task. 16 figures, 1 table.

Radiation levels during operation
For full-power operation, the four major sources of radiation are: neutrons and gamma rays penetrating the sides of the shield tank; nitrogen-16 activity in the primary coolant; radiation leakage up and down the space between the reactor vessel and shield tank and scattering to accessible areas; and gamma rays from inelastic scattering of fast neutrons in the core. These four sources are discussed, and calculated radiation levels in important areas are given.
