Power plant reject heat utilization: an assessment of the potential for wide-scale implementation
An assessment of the relative economic and heat utilization merits of plant reject heat utilization systems was made in an effort to indicate those technologies that show the greatest potential for wide-scale implementation in the power generating industry. The heat utilization systems were designed to accommodate the yearly cooling needs of a 1000-MW(e) power plant. Thus, for the purposes of this study, it was assumed that these systems replaced the cooling tower as the primary condenser cooling water heat dissipation system. Implementation potential and user incentive considerations were used in assessing the technologies. Assessment of the implementation potential included economic, marketing, and power plant performance criteria. The user incentive assessment essentially viewed the use of reject heat from the user's perspective. Heat costs and performance characteristics of the heat utilization system were the criteria used in this assessment. The two analyses were combined in the overall assessment. The overall assessment indicated that extensive pond aquaculture offered the greatest potential for wide-scale implementation. This was followed by animal rearing, algal pond, greenhouse, intensive aquaculture and undersoil heating systems. Based on this assessment, it is recommended that extensive pond aquaculture should receive top research priority. Animal rearing, algal pond and greenhouse research …

Kilowatt Isotope Power System: component test procedure for the ground demonstration system multi-power level combined rotating unit. 77-KIPS-61
This test procedure (No. 402) provides a detailed description of the verification methods which shall be used in the developmental program to be conducted on the Combined Rotating Unit-(CRU) of the Kilowatt Isotope Power System KIPS, to fulfill the requirements of the Ground Demonstration Test Plan. The test objectives were to: establish operating conditions, overspeed conditions and to measure basic performance; measure output power; record spin-down data and calculate bearing losses; calculate turbine efficiency at steady state using spin down data and previously determined pump and alternator performance data; test 500 W(e) and 2000 W(e) units by replacing necessary hardware in one of the units and measuring basic performance; and test one of the units in the horizontal axis to demonstrate zero g operation.

Internal dosimetry technical basis manual
The internal dosimetry program at the Savannah River Site (SRS) consists of radiation protection programs and activities used to detect and evaluate intakes of radioactive material by radiation workers. Examples of such programs are: air monitoring; surface contamination monitoring; personal contamination surveys; radiobioassay; and dose assessment. The objectives of the internal dosimetry program are to demonstrate that the workplace is under control and that workers are not being exposed to radioactive material, and to detect and assess inadvertent intakes in the workplace. The Savannah River Site Internal Dosimetry Technical Basis Manual (TBM) is intended to provide a technical and philosophical discussion of the radiobioassay and dose assessment aspects of the internal dosimetry program. Detailed information on air, surface, and personal contamination surveillance programs is not given in this manual except for how these programs interface with routine and special bioassay programs.

Considerations of bunch-spacing options for multi-bunch operation of the Tevatron Collider
This discussion will consider a number of points relevant to limitations, advantages and disadvantages of various arrangements of bunches in the Tevatron proton-antiproton collider. The considerations discussed here will be limited to: (a) bunch spacing symmetry and relation to the relative luminosity at B0 and D0 and the beam-beam interaction with separated beams; (b) bunch spacing constraints imposed by Main Ring RF coalescing and the optics of beam separation at B0 and D0; and (c) bunch spacing constraints imposed by injection and abort kicker timing requirements, and by the Antiproton Source RF unstacking process. 20 figs., 17 tabs.

Dedicated medical ion accelerator design study. Final report
Results and conclusions are reported from a design study for a dedicated medical accelerator. Basing efforts on the current consensus regarding medical requirements, the resulting demands on accelerator and beam delivery systems were analyzed, and existing accelerator technology was reviewed to evaluate the feasibility of meeting these demands. This general analysis was augmented and verified by preparing detailed preliminary designs for sources of therapeutic beams of neutrons, protons and heavy ions. The study indicates that circular accelerators are the most desirable and economical solutions for such sources. Synchrotrons are clearly superior for beams of helium and heavier ions, while synchrotrons and cyclotrons seem equally well suited for protons although they have different strengths and weaknesses. Advanced techniques of beam delivery are of utmost importance in fully utilizing the advantages of particle beams. Several issues are invloved here. First, multi-treatment room arrangements are essential for making optimal use of the high dose rate capabilities of ion accelerators. The design of corresponding beam switching systems, the principles of which are already developed for physics experimental areas, pose no problems. Second, isocentric beam delivery substantially enhances flexibility of dose delivery. After several designs for such devices were completed, it was concluded that high …

Elastic properties of monoclinic hafnium oxide
The elastic properties of monoclinic hafnium oxide were studied as functions of porosity, temperature and grain size. An important finding of this study was that hafnium oxide is subject to microcracking when the grain size exceeds a critical value between 2 and 3 mu m. The behavior of the elastic moduli with porosity and temperature for crack-free hafnium oxide was typical for polycrystalline ceramics. The nature of the thermal expansion and the internal friction supported this finding. The elastic properties for the microcracked material exhibited trends similar to those observed for other microcracked materials. However, some new characteristics of the microcracking effects were observed in this study. An increase in internal friction was associated with the microcrack healing process. It was also found that there is an atmospheric effect that enhances microcrack growth. Additionally, thermal treatments of microcracked hafnium oxide were found to result in significant changes in the microcrack system.
