Reprocessing facility for Advanced fuels in Lead cells). Based on the dissolution experiments carried out on unirradiated single pellets and systematic studies related to the third phase formation, the flow sheet, prepared earlier for the oxide fuel was modified. Activities Chemistry Group: Presently there are 4 subdivisions: Fuel Chemistry Division (FChD), Materials Chemistry Division (MCD), and Chemical Facilities Division (CFD). Facilities include Far-IR Fourier Transform Infrared Spectrometer, Fluorimeter RF-5000, Impedance Spectrometer and Inductively Coupled Mass Spectrometer (ICP-MS), Alpha Spectrometer, Liquid Scintillation Counter, High Purity Germanium Detector, Neutron Counter ED-XRF, HPLC, SFC, Ion Chromatography, Gas Chromatography, etc. Among various achievements of the Group, Radioisotope production for medicinal importance is the ongoing important projects and has societal impact.
