What are projects about nuclear controlled fusion reactor to achieve Q > 1

Click For Summary

Discussion Overview

The discussion centers around projects related to nuclear controlled fusion reactors with the aim of achieving a Q value greater than 1. Participants explore various initiatives, their goals, and the technical specifications involved in reaching this milestone.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant notes that a thermonuclear bomb could be considered to have a Q greater than one, but it lacks the control desired for practical applications.
  • Another participant mentions that ITER aims for a Q of 10 to ensure sufficient thermal efficiency for power plant designs.
  • Details about ITER's operation, including the use of a hydrogen plasma torus at over 100 million °C and the expected output of 500 MW of fusion power, are shared.
  • Links to additional resources about the Fusion Ignition Research Experiment (FIRE) and its optimization strategies are provided by a participant.
  • A participant shares information about the JT-60 project, indicating that it achieved gains of approximately 1.25.

Areas of Agreement / Disagreement

Participants present various projects and their goals, but there is no consensus on a single approach or outcome. Multiple competing views and projects are discussed without resolution.

Contextual Notes

Some participants reference specific performance metrics and operational conditions of different fusion projects, but the discussion does not clarify the assumptions or definitions underlying these metrics.

What are projects about nuclear controlled fusion reactor to achieve Q > 1, or possibly obtain Q > 1.

You have asked this in another thread, why are you making another thread?

I think a thermonuclear bomb would qualify as having Q greater than one, but that is not controlled as well as anyone would like.
 
The goal of ITER is to achieve a Q = 10, to have a high enough thermal efficiency for a power plant design.
 
I was wondering about that but I could not find the specific information until now.

It is based around a hydrogen plasma torus operating at over 100 million °C, and will produce 500 MW of fusion power.

Here's a few links about the performance of JT-60 if you're interested. I guess they were able to reach gains of 1.25 or thereabouts.
