The conference included 10 papers, one of which appeared previously under conference number Conf: 770675-1. Separate abstracts were prepared for the remaining nine papers. (JFP)

Some general approaches to remote blanket change and servicing operations are briefly outlined for the LLL Field Reversed Mirror and Tandem Mirror Fusion reactors. Remote servicing system design requirements are briefly discussed. (RME)

Investigation and assessment of the potential degrading and destructive effects associated with the nuclear electromagnetic (EMP) phenomena has created a large technological base. This base is indeed quite broad owing to the unique and system-pervasive character of the EMP. One of the aims of an emerging discipline, such as that associated with EMP, is to provide for adequate transfer and integration of the developing technology into the overall engineering community. The needs of the community and how EMP hardening and protection information can be transferred or exchanged are reviewed. Many of the current and generally available sources of information are listed, examples of interchange methods are provided, and problems of developing specifications, standards, and suitable guidelines for design and incorporation of protection are also discussed.

Corrosion of uranium in O/sub 2/ or H/sub 2/O atmospheres can be inhibited by first oxidizing the surface and then exposing it to organic vapors at temperatures near 400/sup 0/C. There is evidence that a polymeric material is formed on the surface and that it may be responsible for the corrosion inhibition. Polymer coatings can also be prepared using an RF discharge. This paper describes experiments in which uranium surfaces were exposed to an RF discharge and then evaluated as to their corrosion resistance and surface characteristics. Various plasma gases were used and in each case corrosion inhibition resulted. Samples for corrosion tests and ESCA/Auger examinations were prepared at the same time. The ESCA spectra reveal the formation of hydroxyl groups on uranium surfaces exposed to the RF discharges. Comparisons with corrosion tests suggest that a low surface hydroxyl concentration is associated with a low corrosion rate. The experiments reveal variations in both surface composition and corrosion reactivity which are related to the plasma gas used. These results are discussed in terms of possible reactions occurring between uranium and the RF plasma.

The requirements a heavy ion accelerator must meet in order to initiate practical thermonuclear microexplosions are summarized. Particular emphasis is given to the question of maximum allowable ion energy.

The tandem mirror magnetic geometry is described, followed by an analysis of the magnet set designed to meet the requirements of the TMX experiment. The final magnet line-up is composed of a baseball coil with two C coils for each plug, six solenoidal coils for the central cell, and two RC coils plus one octupole coil for each transition.

One of the more useful tools to assure the reliability of results from analytical procedures is the interlaboratory comparison method. The present exercise was undertaken primarily to obtain a measure of the reliability of analyses performed by several laboratories on autopsy samples in support of the United States Transuranium Registry (USTR). The results of these and other leading laboratories which routinely conduct similar analyses will be presented and compared. Three types of bovine tissue were prepared for distribution at three levels of plutonium concentration near the detection level normally encountered in autopsy samples.
