Preliminary consideration of CFETR ITER-like case diagnostic system

Area of Science:

• Fusion Energy Research
• Plasma Physics
• Nuclear Engineering

Background:

• The Chinese Fusion Engineering Test Reactor (CFETR) is a novel superconducting tokamak designed to advance fusion energy.
• CFETR aims to bridge the technological gap between ITER and future DEMO reactors.
• Two operational phases, the ITER-like case and the towards DEMO case, are considered for CFETR.

Purpose of the Study:

• To present preliminary considerations for the ITER-like diagnostic case of the CFETR.
• To develop and evaluate different versions of the diagnostic system based on the ITER design.
• To define the goals, functions, and performance of proposed diagnostic systems.

Main Methods:

• Adaptation and enhancement of the ITER diagnostic system for the CFETR's ITER-like case.
• Development of three distinct versions (A, B, and C) of the diagnostic system with increasing complexity and coverage.
• Analysis of system performance, redundancy levels, and required research and development.

Main Results:

• Version A focuses on machine protection and basic control.
• Versions B and C are designed for machine protection, basic, and advanced control.
• Version C incorporates enhanced redundancy for improved measurement capabilities.

Conclusions:

• Multiple diagnostic system configurations are proposed for the CFETR's ITER-like phase.
• The versions offer varying degrees of functionality, from basic protection to advanced control and measurement.
• Further R&D is identified as necessary for the implementation and optimization of these diagnostic systems.
