Disney World should have gone nuclear
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

This article outlines the constraints for operation of tokamaks. The operating space is restricted by several limitations among which the plasma performance has to be optimized. Hard limits which lead ultimately to a disruption and may damage the first wall as well as soft limits resulting in a reduction of the energy content of the plasma can occur. The operational limits can be summarized in two general groups: excessive radiation from the plasma, and violation of global as well as local MHD stability boundaries.
