ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

ITER is a joint international fusion facility to demonstrate the scientific and technological feasibility of fusion power for future commercial electric power facilities. ITER is being designed and constructed in France with support from seven domestic agencies. In accordance with the Article 14 of the ITER Agreement, ITER shall observe French Regulations. Among various existing regulatory documents the French Decree 99-1046 concerning pressure equipment and the French Order dated 12th December 2005 concerning nuclear pressure equipment formulate the requirements for design, manufacture and operation of the pressure and nuclear pressure equipment.The ITER Tokamak Cooling Water System (TCWS) is comprised of 4 primary heat transfer systems and their supporting systems. TCWS provides the cooling water to client systems for heat removal during plasma operations and provides the primary confinement for the radioactive substances entrained in the cooling water. The main sources of radioactive substances include Tritium, Activated Corrosion Products (ACP), 14C isotope, 16N and 17N isotope. The concentration of these radioactive substances is a key parameter for the classification of TCWS equipment in accordance with French regulations.The paper will describe the process for classifying TCWS pressure equipment in accordance with French Regulations.
