WIPP: Lessons in transportation safety
As part of a future consent-based approach by the federal government to site new deep geologic repositories for nuclear waste, local communities and states that are considering hosting such facilities are sure to have many questions. Currently, the Waste Isolation Pilot Plant in New Mexico is the only example of such a repository in operation, and it offers the opportunity for state and local officials to visit and judge for themselves the risks and benefits of hosting a similar facility. But its history can also provide lessons for these officials, particularly the political process leading up to the opening of WIPP, the safety of WIPP operations and transportation of waste from generator facilities to the site, and the economic impacts the project has had on the local area of Carlsbad, as well as the rest of the state of New Mexico.

In the GAMMA 10 tandem mirror, neutral hydrogen densities in the central-cell and anchor-cell have been estimated by measuring spatial profiles of H line-emission with absolutely calibrated H line-emission detectors. Absolute measurements of H line-emission enable us to evaluate the neutral density based on the collisional-radiative model. Recently, single channel H line-emission detectors were installed in plug/barrier cells, where the axial confining potentials are produced by electron cyclotron resonance heating. We studied the neutral particle behavior in the plug/barrier cells for the first time using the newly installed H line-emission detectors. Moreover we have designed and installed a multi-channel H line-emission detector system to study the neutral hydrogen behavior in the plug/barrier cell.
