Sellafield awards $3.86B in infrastructure contracts to three companies
Sellafield Ltd., the site license company overseeing the decommissioning of the U.K.’s Sellafield nuclear site in Cumbria, England, announced the award of £2.9 billion (about $3.86 billion) in infrastructure support contracts to the companies of Morgan Sindall Infrastructure, Costain, and HOCHTIEF (UK) Construction.

An improved method for Monte Carlo simulation is described to calculate the neutral-particle transport in a divertor throat and to evaluate the helium removal efficiency from a burning plasma. The required pumping speed for the helium removal is discussed with special emphasis placed on the efferts of long exhausting duct and of scrape-off plasma variables. The analysis for International Tokamak Reactor (INTOR) single null divertor suggests a possibility that the pumping requirement for INTOR could be drastically eased—e.g., <104 l/s, for the high scrape-off plasma density of the order of 1013 cm-3.
