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.

Basic properties of the plasma edge in magnetically confined fusion plasmas are summarised. Starting from the magnetic topology of tokamaks we describe the transport of the scrape-off layer including drifts and the consequences of the electrostatic Debye sheath in front of the plasma facing components. The relation between the local plasma density and temperature at the targets and the fluxes of power and particles in the SOL is discussed. The transport of the fuel neutrals (hydrogen atoms and molecules) is described.
