Feasibility study of a fission supressed blanket for a tandem-mirror hybrid reactor

Description: A study of fission suppressed blankets for the tandem mirror not only showed such blankets to be feasible but also to be safer than fissioning blankets. Such hybrids could produce enough fissile material to support up to 17 light water reactors of the same nuclear power rating. Beryllium was compared to /sup 7/Li for neutron multiplication; both were considered feasible but the blanket with Li produced 20% less fissile fuel per unit of nuclear power in the reactor. The beryllium resource, while… more

Shawnee test program: TVA Shawnee Test Facility. Technical progress report, April 6-May 6, 1981

Description: The test obtective for April was to evaluate sodium thiosulfate in limestone scrubber slurry as inhibitor of sulfite oxidation. The resulting effect on saturation levels of calcium sulfate (CaSO/sub 4/.2 H/sub 2/O; gypsum) and scaling in the system was of prime importance. As an antioxidant, S/sub 2/O/sub 3//sup =/ functions as a scale inhibitor by reducing SO/sub 4//sup =/, a known scale former. To meet the test objective, the scrubber was operated in a scaling mode as a base case; finally, th… more

Studies of autoionizing states relevant to dielectronic recombination. Progress report for the third year

Description: An important loss process in CTR plasmas is the process of dielectronic recombination, which proceeds via autoionizing states. At this date, however, this problem is not fully understood, largely because of the nearly complete lack of fundamental atomic data on high excited autoionizing states. In this document, we outline the continuation of a program to investigate the properties of autoionizing states of alkaline earth metals by means of a novel laser excitation technique developed at SRI.
