Steam Generator Test Facility (SGTF) is set up in IGCAR to optimize the design of Steam Generators (SG) for Fast Breeder Reactors. In the SG of SGTF heat exchange takes place from sodium which enters at 525 ºC and leaves at 355 ºC temperature to the water/steam which enters at 235 ºC and ... Read More

Kinetics of the Carbothermal Reduction of Ilmenite: Grain Pellet Model

S. Savithri[1], and M. S. Manju[1]
[1] National Institute for Interdisciplinary Science and Technology Trivandrum, India.

A novel mechanism for the carbothermal reduction of Ilmenite is proposed and validated with the help of a comprehensive mathematical model. A time-dependent isothermal pellet-grain model is used to simulate the kinetic behaviour of a spherical pellet of ilmenite (FeTiO3) in CO/CO2 ... Read More

Local Electroporation of Single Adherent Cells by Micro-Structured Needle Electrodes

[1] University of Rostock, Chair of Biophysics, Gertrudenstr. 11a, 18057 Rostock, Germany
[2] Microsystem Material Laboratory, Department of Microsystems Engineering (IMTEK), University of Freiburg, Germany

In spite of its low throughput, Patch-Clamp is the established method for intracellular measurements of the transmembrane potential. To address this problem, we have developed new biosensor-chips with micro-structured needle electrodes (MNEs). MNE-penetration of single cells growing on ... Read More

Magneto-structural Analysis of Fusion grade Superconducting Toroidal Field Coils

A. Amardas [1], and S. Dwivedi[2]
[1] Institute for Plasma Research, Gandhinagar, Gujarat, India
[2] COMSOL Multiphysics Pvt. Ltd, Bangalore, Karnataka , India

In this paper, detail magnetostructural analysis of fusion grade superconducting toroidal field coils that are used in ‘tokamaks’ is presented. The stresses that arise due to Lorentz forces in large size superconducting coils that carry high currents are of catastrophic type in nature. ... Read More

Mathematical Modeling of Direct Borohydride Fuel Cells and its Experimental Validation

[2] Department of Chemical Engineering, Indian Institute of Science, Bangalore , Karnataka, India
[3] Solid State & Structural Chemistry Unit, Indian Institute of Science, Bangalore , Karnataka, India

  Direct borohydride fuel cells (DBFCs) use sodium borohydride (NaBH4) as fuel and hydrogen peroxide (H2O2) as an oxidant. A mathematical model encompassing mass balance of ionic species in different regions of the DBFC is developed. Both the oxidation of sodium borohydride and ... Read More

Thermal Analysis of Intermediate Heat Exchanger in a Pool Type Fast Breeder Reactor

S. Agarwal[1], C. A. Babu[1], P. Kalyanasundaram[1], and G. Vaidyanathan[1]


[1]Fast Reactor Technology Group, Indira Gandhi Centre for Atomic Research, Kalpakkam

Intermediate heat exchanger (IHX) in a pool-type liquid metal cooled fast breeder reactor is an important heat exchanging component as it transfer heat from the radioactive primary sodium in the pool to the non-radioactive secondary sodium. The secondary sodium ultimately heats up water ... Read More
