The work of the ITER Organization is supervised by its top body, the ITER Council. It has the authority to appoint senior staff, amend regulations, decide on budgeting issues, and allow additional states or organizations to participate in ITER.
The ITER Council is comprised of four representatives per ITER Member. The Chair and Vice-Chair of the Council are elected from amongst the Members and can hold office for up to four years. Meetings are held at least twice a year; a communiqué is issued to the press after each meeting.
The Council is supported by two advisory bodies that assemble in the intervals between the ITER Council meetings.
The role of the Science and Technology Advisory Committee is to advise the Council on science and technology issues that arise during the course of ITER construction and operation. Members of the committee are chosen for their outstanding technical qualifications and experience.
The Management Advisory Committee advises the Council on strategic management issues during the development of the ITER Project such as budget allocations, the effective application of privileges and immunities to the Organization and the staff, and recommended administrative action to facilitate the work of the project.
