On February 14 and 15, 1978, a workshop on solar power development and thermal and thermochemical energy storage technology was held at Golden, Colorado. These proceedings contain the record of this workshop. They are divided into two volumes. Volume I presents an analysis and condensation of information discussed in round-table plenary sessions.

This summary report presents a condensation of the designs as developed from requirements and concept selection to preliminary design. The study consists of the following six tasks: (1) Design requirements: establish design environmental conditions and criteria. Develop methodology to both assess SKSS reliability and performance, and minimize life cycle costs. (2) Conceptual design: develop at least two SKSS conceptual designs for both barge and spar platform (eight in all). Consider commercial plant SKSS, verify feasibility, define problem areas, estimate life cycle cost. Develop deployment, operation and maintenance scenarios. Recommend an SKSS concept for each platform. (3) Preliminary design; prepare preliminary designs for two SKSS concepts selected by NOAA/DOE. Optimize the designs, provide deployment and retrieval procedures, support requirements, evaute reliability and performance. Assess effects of watch circle and water depth variation. (4) Development and testing recommendations: recommend programs required to confirm design assumptions and performance predictions, including material and component development, and soils investigation. Estimate cost and schedule required to perform these programs. (5) Cost-time analysis: develop a detailed cost and schedule for the acquisition, transportation, deployment, inspection, maintenance, spares, replacement and salvage for the SKSS designs. (6) Commercial plant SKSS recommendations: assess applicability of designs to commercial plant SKSS. …

A tutorial overview of point-focusing parabolic collectors is presented. Optical and thermal characteristics of such collectors are discussed. Data representing typical achievable collector efficiencies are presented and the importance of balancing collector cost with concentrator quality is argued through the development of a figure of merit for the collector. The impact of receiver temperature on performance is assessed and the general observation made that temperatures much in excess of 1500 to 2000/sup 0/F can actually result in decreased performance. Various types of two-axis tracking collectors are described, including the standard parabolic deep dish, Cassegrainian and Fresnel, as well as two forms of fixed mirrors with articulating receivers. The present DOE program to develop these devices is briefly discussed, as are present and projected costs for these collectors. Pricing information is presented for the only known commercial design available on the open market.

Refinements of the design of the 50 MT/year Experimental Process System Development Unit (EPSDU) have been made and competitive bids have been received from mechanical, electrical, and structural contractors. Emergency procedures have been defined to counter a variety of contingencies disclosed in operations and safety reviews. Work continues with the fluidized-bed model to define conditions under which useful segregation of large particles can be obtained. Experimental work with an electrolytic cell for zinc chloride disclosed no significant increase in power efficiency by steps taken to increase electrolyte circulation. On the basis of materials compatibility and permeability tests, 310 stainless steel was chosen for the shell of the fluidized-bed reactor and SiC-coated graphite for the liner. Experiments on the volatility of lead, iron, and cadmium at the ppM level in zinc at its boiling point are being continued with provisions being made to withdraw molten samples so as to avoid segregation on freezing, believed to be the cause of earlier discrepancies.

Progress in the development of LMFBR and GCFR breeding blanket design parameters is reported under the following headings: interface self-shielding and advanced blanket investigations.

Many of the current techniques for fabricating experimental targets appear to be directly extendable to the high-rate, low-cost production of reactor targets. This report describes several new techniques that, in conjunction with the expansion of existing techniques, can constitute a target factory. We have evaluated this concept on the basis of a generalized reactor target design and the projected specifications of reactor-grade targets.
