Startup looks to commercialize inertial fusion energy
Another startup hoping to capitalize on progress the Department of Energy’s Lawrence Livermore National Laboratory has made in realizing inertial fusion energy has been launched. On August 27, San Francisco–based Inertia Enterprises, a private fusion power start-up, announced the formation of the company with the goal of commercializing fusion energy.

Inefficient control of the water level in a steam generator of a nuclear power plant is responsible for frequent unscheduled reactor trips. This problem is particularly critical at low power, when the steam generator exhibits the "swell and shrink" phenomenon and flow rate measurements are highly unreliable. The design of a proper controller capable of avoiding expensive shutdowns is eagerly sought for increasing the availability of the plant. In this paper, we present an extension of an adaptive, stable, fuzzy controller, whose design parameters are optimized via a genetic algorithm. Computer simulations confirm that the devised controller bears good performances in terms of small oscillations and fast settling time even in the presence of steam flow disturbances.
