The Reactor Systems Design Division (RSDD) is engaged in the design, analysis, and integration of advanced fusion reactor systems with a focus on tokamak-based fusion energy technologies. The division carries out multidisciplinary activities related to reactor systems design for configuration development that includes analysis of magnet, blanket and Divertor & first wall systems, fusion neutronics, shielding design & optimization, tritium breeding analysis, and nuclear safety assessment. Advanced computational tools, reactor systems codes, and multi-physics simulation methodologies are extensively utilized for integrated reactor design studies, performance optimization, and systems engineering analysis.
The division specializes in reactor design using systems codes and other relevant physics codes for the assessment of overall plasma performance, engineering feasibility, power balance, thermal loads, heating and current drive systems, magnet systems, port plug design studies, diagnostics integration, cooling systems, reactor maintenance strategies, and overall plant integration. Computational studies involving neutron transport, electromagnetic analysis, thermal hydraulics, activation, radiation shielding, structural integrity, and safety analysis are carried out to support the development of reliable and efficient fusion power systems. The division also contributes to the analysis and physics simulations of experimental data from ADITYA-U and SST-1.
The division aims to establish safe, sustainable, and economically viable fusion energy systems through innovation and collaboration with national and international fusion programs, while strengthening indigenous capabilities in fusion reactor engineering and integrated reactor systems design using validated simulation tools and high-performance computing.
