Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

The first results on plasma control with the new plasma control system of Tore Supra are described. The system has been especially designed for long-pulse operation: Plasmas are controlled by reference signals, which can be varied in real time by using diagnostic measurements. On-line determination of the global plasma equilibrium has enabled new operation scenarios in which both the power from the poloidal field generators and the total lower-hybrid (LH) power are used to control the plasma. Experiments with feedback control of the safety factor on the plasma boundary, control of the LH-driven current, control of the flux on the plasma boundary, and control of the internal inductance are demonstrated. Finally, future modifications to the system, aimed at controlling the current profile during long-pulse operation, are discussed.
