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).

Experiments on plasma heating with waves in the ion cyclotron range of frequencies that have been performed on the DIII-D tokamak are reviewed. High-power experiments (Prf [greater than or approximately equal to] 1 MW) have been performed using the ion Bernstein wave (IBW) (1988-1990), 32-MHz fast waves (FWs) (1990-1991), 60-MHz FWs (1991-1999), and higher-frequency FWs up to 120 MHz (1994-present). Efficient electron heating of the core plasma has been obtained in all of these regimes, with the exception of the IBW experiments.
