WIPP improves utility shaft safety, begins infrastructure project
Harrison Western Shaft Sinkers (HWSS), the company drilling a new utility shaft at the Department of Energy’s Waste Isolation Pilot Plant in New Mexico, has retained a safety culture expert following a near-miss accident in the shaft late last year. The safety expert will conduct monthly facilitated discussions with crews working on the shaft to reinforce expectations for identifying concerns regarding unsafe circumstances, according to a recent report by the Defense Nuclear Facilities Safety Board (DNFSB).

The low aspect ratio or spherical tokamak offers the prospect of burning plasmas in a compact simple system at a lower cost than in conventional tokamaks. The promising results obtained on START and other small spherical tokamaks have led to the approval of higher current devices at the MA level where the key issues of operational limits, confinement, plasma exhaust and steady state potential can be tested under more demanding conditions. From such devices it is a comparatively small step to a burning plasma and such devices have already been proposed. The compact nature of the spherical tokamak and its steady state potential make it ideally suited as a component test facility and also as a low cost, small unit size power plant capable of advancing the timetable for fusion exploitation.
