Technology Roadmap Sections and Deliverables
- 2ICF - Laser Confined Nuclear Fusion
Roadmap Overview
The working principle and architecture of Laser Confined Nuclear Fusion is shown in the schematic below.
Nuclear fusion power generation fundamentally consists of fusing atoms to form heavier ones with a release of energy through neutrons. One of the main technology branches for demonstrating fusion power is Inertial Confinement Fusion, ICF which involves rapidly compressing a D-T (Deuterium-Tritium) fueled target pellet using some of the world’s most powerful lasers. The National Ignition Facility, at LLNL employs 192 UV laser beams at ~2MJ to converge on a gold cylinder, the size of a dime to generate x-rays and accelerate the fuel radially inward in less than 1 billionth to produce helium and high energy neutrons that could be captured to create a future energy source.
Design Structure Matrix (DSM) Allocation
The 2-ICF tree shows us that Laser Confined Nuclear Fusion is part of larger global Nuclear Fusion Power initiative to harness fusion power. The DSM and tree both show that 2-ICF requires the following technologies at the subsystem level 3: 3LAS Laser, 3TAR ICF Targets, 3DIA Diagnostics, 3CTP Cryogenic Target Positioning, and 3CHB Target Chamber. Each level 3 subsystem also require enabling technologies shown as level 4 systems.
Roadmap Model using OPM
The Object-Process-Diagram (OPD) of the 2ICF Laser Confined Nuclear Fusion is provided in the figure below. This diagram captures the main object of the roadmap, its various processes and instrument objects, and its characterization by Figures of Merit (FOMs). The Fusing Process is unfolded to show sub-processes and their instrument objects.
Unfolding the Fusing Process at level SD1
An Object-Process-Language (OPL) description of the roadmap scope is auto-generated and given below. It reflects the same content as the previous figure, but in a formal natural language.
Figures of Merit
The table below shows a list of FOMs by which Laser Confined Nuclear Fusion can be assessed. FOMs on the list related to fusion reactions such as neutron yield and net energy gain are similar to other confined fusion experiments.
