This is the first issue coming in the New Year. I take this opportunity to wish you all a very happy New Year on my personal behalf and on behalf of the member of the editorial team. In the first technical article, Shri M. L. Jayalal has given an account of the studies on the application of genetic algorithms in nuclear fuel management. Dr. R. N. Viswanath has analyzed the functional applications of nanoporous metallic materials in the second technical article. This issue’s Young Officers’ forum features the article by Shri Prasant Kumar Nayak, on single-cycle approach for partitioning of minor actinides from high-level liquid waste Shri Varun Hassija has shared his experience in analyzing alpha factor model for common cause failure in engineered safety systems using mapping technique in the Young Researchers’ Forum. Dr. Sekhar Basu, Chairman, Atomic Energy Commission and Secretary, Department of Atomic Energy, Government of India and Director, BARC visited our Centre and during the visit he inaugurated the 2MIGD Desalination Plant. We are happy to share with you the awards, honours and distinctions earned by our colleagues. We look forward to your comments, continued guidance and support. With my best wishes and personal regards, Yours sincerely, Chairman, Editorial Committee, IGC Newsletter & Associate Director, Resources Management Group Director's Desk IGC Newsletter New Year Message My dear colleagues, of permanent magnet sodium flow meters, performance testing It gives me a great pleasure in wishing you and your families a of Sonar device to measure very happy, healthy and prosperous New Year 2016, full of flow induced vibration of fuel achievements, satisfaction and glory filled with bliss. As we enter subassemblies etc. into the New Year, it is time to look back and cherish the successes of the year that passed by, having achieved considerable progress A position paper on the need in the mission programmes of our Centre. FBTR, one of the and rationale for metal fuel test flagships of our Centre, continues to play an important role in reactor has been submitted testing the fuel, structural materials and special neutron detectors to DAE for consideration of in towards development of Fast Reactor programme. During the year, principle approval. A conceptual 23rd irradiation campaign was completed. During this campaign, core design for 100 MWt Metal reactor was operated at its highest power level of 24.5 MWt producing Fuel Test Reactor has been evolved and that of two more oxide 5 MWe, which was fed to TNEB grid. We started our 24th campaign fuelled Commercial Breeder Reactors of 600 MWe is being a few days back. Prior to starting the campaign, four control rods evolved with improved economy and enhanced safety features along with their outer sheaths were replaced as they attained meeting the GEN IV safety criteria. A 5/8th scale 90° sector model neutron fluence close to the limiting value. As part of production of simulating the hot pool of future FBRs has been commissioned for Uranium-233 in FBTR, 122 Thorium sub-assemblies were loaded conducting hydraulic studies in water. A new facility has also been th th in the 10 and 11 rings of the core. All the short and medium commissioned in Engineering Hall-IV to study the flow induced term recommendations of SARCOP including post-Fukushima and vibration characteristics of a cluster of subassemblies of the core 233 seismic retrofits have been implemented. KAMINI, the only U of FBR. I am happy that the expertise acquired over the period based operating reactor in the world, is being operated successfully of time in the domain of Seismic Qualification experiments has for neutron radiography. It continues to provide excellent services been utilized in carrying out experiments for various Departmental in testing the pyro devices of all space launches, an important programmes using the shake table, some of them being, spent programme of the Department of Space. High temperature fission fuel storage trays of spent fuel storage facility in Tarapur, main chambers required for neutron flux measurement of PFBR have annunciator system prototype panel for the KAPP-3&4 and been successfully tested at KAMINI. RAPP-7&8. We were able to demonstrate the life of the bellows We have accumulated rich experience in Post-Irradiation used in the passive valves of Advanced Heavy Water Reactor Examination (PIE) of irradiated FBTR components, over the years. (AHWR), using the in-house developed multiple bellows test PIE carried out on a control rod discharged from FBTR has yielded facility. valuable information about its performance. The infrastructure of The operations of CORAL have given immense experience in the Hot cells is being enhanced for handling and examining metallic design of Demonstration Fast Reactor Fuel Reprocessing Plant fuel and structural materials being irradiated presently in FBTR and (DFRP) and Fast Reactor Fuel Cycle Facility (FRFCF), especially in taking up the challenging PIE of these materials. the domain of remote handling and maintenance and in achieving PFBR has made significant progress during the last one year product purity. All efforts are being made for early commissioning and our support continues in providing crucial inputs towards of DFRP. commissioning and obtaining safety clearances. I am happy that IGCAR and BHAVINI are working closely to achieve the PFBR Electro refining of U-Pu-Zr alloy (~20 gram scale) in molten criticality and subsequent full power generation at the earliest. LiCI-KCI-PuCI3 electrolyte salt has been demonstrated. Also, direct Some of the major contributions to PFBR in the year passed by are: reduction of 100 gram batches of uranium dioxide to uranium completion of trial run for transportation of six PFBR dummy fuel metal by the new molten salt (LiCI-1wt%Li2O) electrode oxidation sub-assemblies from the Interim Fuel Storage Building to PFBR Fuel process, has been demonstrated with conversion efficiency> Building using a trailer, experimental studies on the performance 98%. Ultrasonic imaging based procedure has been developed of safety grade decay heat removal system, demonstration of for assessment of bond integrity of Zirconium lined ferritic steel in-situ regeneration of secondary cold trap, in-sodium calibration (T91-Zr) double clad for metallic fuel applications. 1 IGC Newsletter Director's Desk Advanced alkoxyacetamide reagents have been synthesized nano-fluids an opto-magneto-rheometer suitable for probing and also the single-cycle methods for partitioning of trivalent field-induced microstructures has been designed and developed. actinides directly from fast reactor high active waste have been Non-contact electromagnetic acoustic transducers and eddy demonstrated. In addition, the organo-functionalized inorganic current array sensor probes have been developed for detection and magnetic materials have been developed and demonstrated of sub-surface defects in austenitic stainless steels.
