Another Milestone in Indian Contribution to ITER - Completion of In-Wall Shield Manufacturing


ITER-India, as a 10% stakeholder in ITER - one of the largest experiments in the history of mankind, added another feather to its cap in terms of achieving a major milestone related to the completion of indigenous manufacturing of the one of the nine procurement packages. The package termed as In-Wall Shields is a complex assembly of ~9000 borated steel blocks. The supplied shields are sandwiched between the double walls of the vacuum vessel of the ITER machine and perform the important function of shielding the components from neutrons and contribute to plasma performance by limiting perturbations due to toroidal field ripple. This is the third milestone achievement by India in a short span of less than year and speaks volumes of the dedication and devotion of all involved inspite of the existing pandemic conditions. The previous two milestones related to the handing over of the base section of the cryostat to ITER and its subsequent installation in the tokamak pit at ITER and the flag off of the final top lid segments of the cryostat. All components delivered to ITER meet the desired standards of safety and quality as per requirements defined by the French Nuclear Regulators. Indigenous development, involving the industry and the scientists and engineers of ITER India, Institute for Plasma Research, demonstrate the ever growing self-reliance related to the development of fusion technologies within the country.


In this context, a video televised ceremony was organised. Speakers on the occasion included eminent scientist Dr. Anil Kakodkar, as the chief guest, Dr Bernard Bigot, Director general ITER organization, Dr. R.B. Grover. Shri K.N. Vyas, Chairman, Atomic Energy Commission conveyed his congratulatory message through Dr. Shashank Chaturvedi, Director IPR.


ITER, currently under construction in south of France at a nuclear site Cadarache, is aimed at exploring and demonstrating a clean green economically viable alternate source of energy through nuclear fusion. The assembly activities are in full swing and the first plasma is expected in December 2025.
