Monitoring of exposure to 1,6-hexamethylene (HDI) monomers and HDI polyisocyanates in Oregon was initiated in 1980 and covered primarily spray painting and related activities. A total of 562 air samples were collected from 60 workplaces during the years 1980-1990 and analyzed for HDI and HDI polyisocyanate content. Of the total, only a small fraction (6%)(More)
The advanced limiter-divertor plasma-facing systems (ALPS) program was initiated in order to evaluate the potential for improved performance and lifetime for plasma-facing systems. The main goal of the program is to demonstrate the advantages of advanced limiter/divertor systems over conventional systems in terms of power density capability, component(More)
Under the APEX program the He-cooled system design task is to evaluate and recommend high power density refractory alloy first wall and blanket designs and to recommend and initiate tests to address critical issues. We completed the preliminary design of a helium-cooled, W–5Re alloy, lithium breeder design and the results are reported in this paper. Many(More)
A compact multi-barrel pellet injector system is being developed for the TJ-II stellarator. Its design is based on the system currently installed at the MST facility (Univ. Winconsin) and will provide maximum flexibility at minimal cost, while also allowing for future upgrades. It is a four-barrel system destined for use both as an active plasma diagnostic(More)
This study, called APEX, is exploring novel concepts for fusion chamber technology that can substantially improve the attractiveness of fusion energy systems. The emphasis of the study is on fundamental understanding and advancing the underlying engineering sciences, integration of the physics and engineering requirements, and enhancing innovation for the(More)
The purpose of the ALPS program is to identify and evaluate advanced limiter/divertor systems that will enhance the attractiveness of fusion power. The highest priority goals at present are achieving high power density, up to 50 MW/m2, and showing compatibility of plasma-facing surfaces with plasma operation. Personnel representing a wide range of(More)
