Beyond the physics and demonstration of ignition

Area of Science:

• Physics
• Energy Science
• Engineering

Background:

• Fusion energy offers a carbon-free power source with abundant fuel and safety benefits.
• Over 50 years of research in inertial confinement fusion (ICF) has focused on achieving ignition and energy gain.
• Current ICF efforts are progressing but have not yet met ignition and energy gain goals.

Purpose of the Study:

• To provide an updated roadmap for achieving commercial fusion power through inertial confinement.
• To identify and implement complementary efforts for developing fusion power.
• To guide the implementation of a roadmap for 'beyond ignition' demonstrations.

Main Methods:

• Developing high repetition rate compression drivers (e.g., lasers).
• Designing, fabricating, and testing high-gain ICF targets (gain of ~100).
• Developing mass production and cost-effective target fabrication and delivery systems.
• Designing and demonstrating reaction chambers for high power plant reliability.

Main Results:

• Progress has been made in understanding ICF physics for ignition and energy gain.
• Key areas for development include drivers, targets, and reactor systems.
• A roadmap is essential for transitioning from current achievements to commercial fusion power.

Conclusions:

• Commercial fusion power via ICF requires a strategic roadmap with parallel development efforts.
• Advancements in drivers, targets, and reactor technology are critical.
• Ongoing conceptual design of power plants is necessary to guide roadmap implementation.
