Adult Fishway Inspections on the Columbia and Snake Rivers, 1984-1985 Annual Report.

Description: Mainstream projects which have adult fish passage facilities are inspected by project operators, fishway attendants, and state and federal fishery agencies. The overall movement of upstream migrants in 1984 appeared to be satisfactory with few delays. Special efforts were made by fishery agencies and Corps personnel to check on potential problems which appeared to exist at The Dalles and John Day Dams this year. However, adult passage facilities were operating ''in criteria'' and fish may have … more

Blanket Optimization Studies for Cascade

Description: A nonlinear, multivariable, blanket optimization technique is applied to the Cascade inertial confinement fusion reactor concept. The thickness of a two-zone blanket, which consists of a BeO multiplier region followed by a LiAlO/sub 2/ breeding region, is minimized subject to constraints on the tritium breeding ratio, neutron leakage, and heat generation rate in Al/SiC tendons that support the chamber wall.

Cs-137 concentrations in Steel Creek in 1984. Revision 1

Description: Measurement of Cs-137 concentrations in Steel Creek, 1984, have shown that L Reactor flow tests have not changed the Cs-137 concentrations and the initial phases of L Pond dam construction have only caused a slight increase in Cs-137 concentrations. The Cs-137 concentrations in 1984 were about 1 to 2 percent of the EPA drinking water concentration guide of 200 pCi/L. The concentration in Steel Creek is essentially the same as in 1980, before any major L Reactor refurbishing. The data obtained i… more

Entry State Distributions of Discrete Yrast Transitions in Heavy Ion Induced Fusion Reactions

Description: Gamma rays emitted during yrast transitions from compound nuclei are detected with a 4..pi.. multielement gamma ray detector system. Both total pulse height (H) and coincidence fold data (k) are obtained for each event. Results presented include entry state distribution states, k and H projections for some of these distributions, and k and H as a function of spin of the yrast transition. 5 figs. (DWL)

Ethiopian Food Situation: International Response

Description: The United States has donated the largest share of the world-wide relief effort. Members of Congress nave passed legislation, the African Famine Relief and Recovery Act of 1985 (2.L. 99-8), authorizing emergency relief assistance to Ethiopia and other famine-stricken countries. Some observers favor trying to remove restrictions that prohibit long-term agricultural development assistance and other forms of economic aid to Ethiopia, but many continue to believe that aid to this Marxist-oriented n… more

ICF reactor economics: identifying the high leverage design features

Description: Parametric studies were carried out for a heavy ion beam (HIB) fusion electric power plant to investigate the effects on the cost of electricity (COE) of variations in several design parameters. In particular, we examined the effects of maximum achievable chamber pulse rate, driver cost, target gain, electric conversion efficiency, and net electric power. We find that with a combination of improvements over our base case, HIB fusion can be economically competitive with other future power source… more

ICF tritium production reactor

Description: The conceptual design of an ICF tritium production reactor is described. The chamber design uses a beryllium multiplier and a liquid lithium breeder to achieve a tritium breeding ratio of 2.08. The annual net tritium production of this 532 MW/sub t/ plant is 16.9 kg, and the estimated cost of tritium is $8100/g.

Potential for efficient frequency conversion at high average power using solid state nonlinear optical materials

Description: High-average-power frequency conversion using solid state nonlinear materials is discussed. Recent laboratory experience and new developments in design concepts show that current technology, a few tens of watts, may be extended by several orders of magnitude. For example, using KD*P, efficient doubling (>70%) of Nd:YAG at average powers approaching 100 KW is possible; and for doubling to the blue or ultraviolet regions, the average power may approach 1 MW. Configurations using segmented apertur… more

Report of the SSC impedance workshop

Description: This workshop focused attention on the transverse, single-bunch instability and the detailed analysis of the broadband impedance which would drive it. Issues discussed included: (1) single bunch stability -- impact of impedance frequency shape, coupled-mode vs. fast blowup regimes, possible stopband structure; (2) numerical estimates of transverse impedance of inner bellows and sliding contact shielded bellows; (3) analytic estimates of pickup and kicker impedance contributions; and (4) feasibi… more
