A program was started in FY 1982 to evaluate the compatibility of WESF-produced CsCl with 316 L stainless steel under the thermal conditions that would be encountered in a geologic repository. The program is funded through the Long-Term High-Level Defense Waste Program of the Department of Energy. The major part of the program involves compatibility testing of six standard WESF CsCl capsules at a maximum CsCl/metal interface temperature of 450/sup 0/C. The capsules are allowed to self-heat to the test temperature in insulated containers and then held at temperature for 2200 to 32,000 h. After thermal aging, the capsules are destructively examined to determine the extent of the metal attack by the CsCl. This report describes the testing procedure and summarizes the activities completed during the first year of the program.

The U.S. Interagency Geothermal Coordinating Council was a multi-agency group charged with identifying and reducing barriers to geothermal energy development in the U.S. Many of the issues covered related to regulations for and progress in the leasing of Federal lands in the West for power development. The IGCC reports are important sources of historical information.

The status of Geothermal PRDA and PON projects administered by the DOE-ID as of the end of FY-1982 is reported. Both programs were instituted to assist the development of the direct application of geothermal energy. The PRDA Program consists of a series of studies designed to investigate the engineering and economic feasibility of geothermal direct applications. The PON Program consists of demonstration projects in which project costs are shared between DOE and the private companies, municipalities, or organizations. During this reporting period, fiscal year 1982, EG and G Idaho provided program management and technical support for 12 demonstration projects and five engineering ad economic studies. Each project is summarized.

This report covers the activities of LBL's Accelerator and Fusion Research Division (AFRD) during 1982. In nuclear physics, the Uranium Beams Improvement Project was concluded early in the year, and experimentation to exploit the new capabilities began in earnest. Technical improvement of the Bevalac during the year centered on a heavy-ion radiofrequency quadrupole (RFQ) as part of the local injector upgrade, and we collaborated in studies of high-energy heavy-ion collision facilities. The Division continued its collaboration with Fermilab to design a beam-cooling system for the Tevatron I proton-antiprotron collider and to engineer the needed cooling components for the antiproton. The high-field magnet program set yet another record for field strength in an accelerator-type dipole magnet (9.2 T at 1.8 K). The Division developed the design for the Advanced Light Source (ALS), a 1.3-GeV electron storage ring designed explicitly (with low beam emittance and 12 long straight sections) to generate high-brilliance synchrotron light from insertion devices. The Division's Magnetic Fusion Energy group continued to support major experiments at the Princeton Plasma Physics Laboratory, the Lawrence Livermore National Laboratory (LLNL), and General Atomic Co. by developing positive-ion-based neutral-beam injectors. Progress was made toward converting our major source-test facility into a long-pulse national …
