CICLOP

Coordination on International Challenges on Long duration OPeration (CICLOP)


Background


The objectives of the CICLOP group that stands for Coordination on International Challenges on Long duration OPeration are to gain experience with steady-state and long pulse operation in actively cooled devices as they are essential to the ITER international experiment and beyond (thermonuclear fusion reactors). The CICLOP group will promote activities, collect and disseminate information on long pulse operation issues.
These objectives will be achieved by sharing best practice, operational procedures, experimental data, simulation programme and coordinating experiments between the fusion-related IEA Technology Collaboration Programmes in close cooperation (by joint meetings and workshops) with the IAEA activities in the same field (i.e. the IAEA Technical Meeting on Long Pulse Operation of Fusion Devices). It is an informal body with no decision-making power. The group will address the physics and engineering issues of long pulse operation for tokamak and stellarator facilities.
More specifically the group will:
  • Collect, compare and disseminate information on steady-state and long pulse operation (e.g. set-up a web site for sharing information and communication with updated information on facilities addressing long pulse operation issues);
  • Set-up a high level contact and network for tokamaks and stellarators addressing long pulse issues including future facilities;
  • Liaise with the International Tokamak Physics Activity (e.g. the Integrated Operational Scenarios group for the development of the long pulse scenarios) and the chair & co-chairs of the CICLOP group to attend the ITPA-CC meeting;
  • Strengthen the synergy between tokamaks and stellarators, e.g. high-level multi-machines database combining physics and technology for long pulse operation;
  • Identify gaps in physics and technology of long pulse operation or limiting factors in duration and propose actions plan to address the identified gaps or limiting factors;
  • Propose action plans to address long pulses issues as identified in the latest version of the ITER research plan (c.f. ITER specific R&D topics for the effective implementation of the ITER Research Plan);
  • Develop a roadmap of activities to be carried out for long-pulse operation of a fusion thermonuclear reactor including physics, technology, engineering, control, and, modelling/theory;
  • Promote experimental and simulation programmes to address key issues specific to long-pulse operation for ITER and DEMO within the frame of the relevant TCP agreement; facilitate exchange of staff, codes, tools procedure and operational practices within the frame of the relevant TCP agreement.
