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.

We present a model of a subcritical neutron multiplying system coupled to an external time-dependent neutron source, within one-group diffusion theory. Within this scheme we show that the problem is fully solvable without any other approximation. Then, we are able to show that all the known results about such systems can be consistently derived. In such a way we are able to discuss various specific aspects that distinguish a subcritical system from a critical one without relying on any other approximations or assumptions. Moreover, we prove that a subcritical system has very different working regimes as the level of subcriticality varies.
