Engineering performance through simplification, efficiency, and resource optimization
1. Context
Within the ITER program, at the PRIMA site in Padua, Synecom supported RFX and Fusion for Energy (F4E) in the development of the Drying System for the SPIDER Beam Source.
The project is part of a highly advanced experimental environment dedicated to nuclear fusion research, where reliability, precision, and operational efficiency are essential requirements.
Synecom’s role went beyond equipment supply, focusing on technical analysis, system optimization, and redesign of the initial concept to improve overall performance and operational sustainability.
2. Objective
To design and deliver a drying system capable of:
- ensuring effective drying of beam source circuits
- preventing corrosion in sensitive components
- supporting helium leak testing operations
- guaranteeing stable and controlled process conditions
- maintaining full compatibility with ITER experimental requirements
3. Challenge
The initial system concept proposed a closed-loop configuration based on:
- nitrogen recovery
- gas-water separation
- process recirculation
4. Solution
Through detailed process analysis, Synecom demonstrated that nitrogen recovery did not provide tangible benefits in this application.
The gas used in the system was:
- inert
- clean
- free from contaminants requiring treatment or reuse
Based on this evidence, Synecom proposed a substantial redesign of the system architecture, moving from a closed-loop to an open-loop configuration.
This engineering decision resulted in:
- a simpler system architecture
- improved operational reliability
- reduced maintenance requirements
- full compliance with performance requirements defined by RFX and F4E
The redesign was developed in close collaboration with the client, including a joint refinement of technical specifications.
5. Implementation
The final system was designed and built as a mobile skid-based unit integrating:
- power supply and control sections
- heating and regulation systems
- measurement and monitoring instrumentation
- process control via PLC Siemens S7-1200
- HMI interface for full operational supervision
The system enables precise control of:
- pressure
- temperature
- flow rate
- humidity
Operating temperatures reach up to 110°C, with continuous process monitoring ensuring full control of drying conditions.
6. Quality & Performance: Validated Excellence
The solution maintained all required performance targets while significantly reducing system complexity.
Key validation aspects included:
- Process Stability: Perfect performance under variable operating conditions.
- Total Integration: Full compatibility with helium leak testing protocols.
- Proven Reliability: Automation and control systems validated for long-term use.
7. Results
- Successful delivery of a fully functional drying system for SPIDER Beam Source
- Approximately 50% reduction in overall system cost compared to the initial concept
- Significant simplification of plant architecture
- Reduced maintenance requirements and failure modes
- Improved operational reliability and system manageability
- Full compliance with RFX and F4E performance specifications
8. Strategic Value
This project highlights a core aspect of Synecom’s engineering approach: the ability to critically evaluate technical concepts and transform them into more efficient, robust, and sustainable solutions.
Rather than acting as a purely execution-focused supplier, Synecom contributed as an engineering partner, supporting design decisions with technical analysis and process understanding.
The result is a system that delivers the same performance requirements through a simpler and more efficient architecture, demonstrating the value of engineering-driven optimization within high-complexity scientific environments.
