Introduction
Analysis of the core content of the standard
GB/T 39225.2-2020 has established a three-stage evaluation system for components that require remote operation in Tokamak fusion reactors:
| Evaluation phase | Key evaluation content | Output document |
|---|---|---|
| Conceptual design phase | Compatibility requirement definition, maintenance level division | Appendix A Audit Table |
| Preliminary design phase | Interface definition, modular design verification | Appendix B/C Task Table |
| Engineering design stage | Welding structure, load transfer test | Appendix D Evaluation table |
Key technical requirements
1. Grading evaluation mechanism
The standard divides teleoperated components into three levels according to maintenance complexity: Level 1 (highest) requires complete simulation testing, and Level 3 only requires basic interface verification.
2. Six compatibility design elements
- Matching degree of layout design and maintenance channel
- Degree of modularity (minimum replaceable unit)
- Protection capability of docking mechanism against misoperation
- Load transfer path optimization
- Self-positioning accuracy (±1mm)
- Welding accessibility assessment
Implementation suggestions
Solutions to typical problems
Case: When disassembling and assembling a divertor assembly, it was found that the working radius of the manipulator was insufficient. According to Article 4.3.3 of the standard, it is recommended that:
- Appendix A should be used to define the minimum operating space during the conceptual design phase
- Critical path accessibility should be verified through physical simulation
- Auxiliary positioning features should be added (Standard 4.3.3.d)
Standard evolution analysis
Compared with the ITER technical specifications, the innovations of this standard are:
- A three-stage closed-loop evaluation process is proposed (Figure 1)
- For the first time, the requirements for bidirectional compatibility verification of teleoperated equipment and components are clarified
- Mandatory provisions for virtual simulation in radiation environments are added (4.3.4)
