inertial confinement

inertial confinement

[in′ər·shəl kən′fīn·mənt]
(nucleonics)
The rapid implosion of a high-density pellet, under bombardment by laser or charged-particle beams, to produce a core that is heated to extremely high temperatures before it can fly apart; proposed as a method for generating power from controlled thermonuclear reactions.

As the NIF Director, Herrmann will work closely with the leadership of the Stockpile Stewardship Program (SSP) across the weapons complex including the national Inertial Confinement Fusion (ICF) Program, as well as the National Security Applications and Discovery Science communities in the United States and globally, to ensure optimal use of the facility and delivery on program goals.
Magnetic confinement fusion uses magnetic fields to trap the fuel in a magnetic 'bottle,' and inertial confinement fusion heats the surface of the fuel pellet until it blows off in a way that causes the remaining pellet to implode.

This work reviews the science of nuclear fusion from the development of the basic scientific ideas concerning the role of fusion in the Sun and other stars to the current progress towards achieving human-controlled fusion energy, covering both the magnetic confinement approach towards insulating hot nuclear fuel with magnetic fields and the newer inertial confinement approach that seeks to capture the fusion energy before the hot fuel has had a chance to expand.
They are not working on the well-publicised magnetic confinement approach to nuclear fusion which is building a facility called Iter in France but instead are preparing for inertial confinement fusion, or "laser energy" as it is sometimes called.
Recommendation: To address the scientific and technical challenges and management weaknesses, and to enhance the NIC review committee's effectiveness, the Administrator of NNSA should direct the Director of the Office of Inertial Confinement Fusion and National Ignition Facility Project to have the NIC review committee report to, and receive direction from, NNSA's Director of the Office of Inertial Confinement Fusion and National Ignition Facility Project on its review activities, instead of reporting to Lawrence Livermore's laboratory Director.
