BARC


Mandate

The Reactor Physics Design Division (RPDD) caters to the reactor physics work for the various ongoing as well as forthcoming reactor systems of the Indian nuclear energy programme. The reactor physicists at RPDD function in various capacities as theoreticians to design reactors, follow operation of the existing research and power reactors, perform experiments to understand the physics of reactors and at the same time look for innovative ideas for development of various reactor physics codes to realize the goals of our nuclear energy program. The research is carried out in fields, which cover the whole gamut of physics of reactors from fundamentals of nuclear data, lattice physics, reactor core analysis, reactor kinetics, reactor operation, reactor fuel management, reactor safety analysis and advanced reactor design studies.
RPDD serves as the nodal center and a one stop solution to all the activities related to Reactor Physics Design work in BARC


Highlights


10/2020

Design of an experimental set-up to measure effective cross section of 98Mo(n, γ) 99Mo using electron beam of energy 10 MeV and average current ~200 microA. Tungsten target (0.18 cm) thick and Be collimator was used to produce maximum Bremsstrahlung. The 98Mo was placed in a light water environment with BeO reflector to maximize the neutron flux. The neutron flux obtained was 6.5x 109 n/cm2/s and the specific activity was 250 micro Ci/g.



9/2020

Several state-of-the-art codes developed for analysis of advanced reactors. ARCH, ARCH-TH, ATES3, M3C, ADWITA have been developed, HEXPIN, Recently a module has been developed for NEM3D to perform coolant density iterations in AHWR. Neutron diffusion code NDIFF3D was modified to use lattice parameter database at any mesh for coolant density and fuel temperature feedback.
