ARCHER

ARCHER (Advanced High-Temperature Reactors for Cogeneration of Heat and Electricity R&D) – is a project focused on the research and development of technologies, components and materials for high-temperature gas-cooled reactors (V/HTR). The project builds on the content of the successfully resolved RAPHAEL project and develops in particular themes of cogeneration and heat utilization from nuclear reactors in industrial processes, the primary circuit and related systems safety, HTR fuel, the end of the fuel cycle, selected components and research and development of high temperature construction materials.

Abstract

In line with the Sustainable Nuclear Energy Technology Platform (SNETP) Strategic Research Agenda (SRA) and Deployment Strategy (DS), the ARCHER project will extend the state-of-the-art European (V)HTR technology basis with generic technical effort in support of nuclear cogeneration demonstration. The partner consortium consists of representatives of conventional and nuclear industry, utilities, Technical Support Organisations, R&D institutes and universities.

They jointly propose generic efforts composed of:

  • System integration assessment of a nuclear cogeneration unit coupled to industrial processes;
  • Critical safety aspects of the primary and coupled system:
    • Pressure boundary integrity;
    • Dust;
    • In-core hot spots
    • Water and air ingress accident evaluation;
  • Essential HTR fuel and fuel back end R&D:
    • PIE for fuel performance code improvement and validation;
    • Back end research focused on radiolysis;
  • Coupling component development:
    • Intermediate heat exchanger development;
    • Steam generator assessment;
  • High temperature material R&D:
    • Completion of graphite design curves;
    • Making use of the experience of state of the art metal in conventional industry;
  • Nuclear cogeneration knowledge management, training and communication.

The activities proposed are embedded in the international framework via GIF; direct collaboration within the project with international partners from the US, China, Japan, and the Republic of Korea; and cooperation with IAEA and ISTC.

The proposal is a technical building block supporting nuclear cogeneration as a fossil fuel alternative for industry and as such supports a high potential contribution to European energy strategy as defined in the SET-Plan. The results of the proposal will be reported to SNETP, to support the strategic pillar of ‘other uses of nuclear energy’, and the establishment of a Nuclear Cogeneration Industrial Initiative, which will include an effective (international) nuclear cogeneration demonstration.
