Abstract

Cherian K. Mathews, the founder of the Chemistry program for fast neutron reactors at Indira Gandhi Centre for Atomic Research (IGCAR), passed away at the age of 89. Mathews made pioneering contributions to the nation's fast reactor program and was known for his administrative skills and innovative entrepreneurship. He established the Radiochemistry Laboratory at IGCAR and played a key role in designing and developing various elements of the laboratory. Mathews also initiated long-term programs in fuel chemistry and sodium chemistry, and equipped the laboratory with state-of-the-art analytical instruments. He was a visionary leader who encouraged collaboration and made significant contributions to the field of chemistry in the fast reactor program. [Extracted from the article]

34. Plutonium reprocessing, breeder reactors, and decades of debate.

Author

Raj, Baldev and Vasudeva Rao, P. R.

*BREEDER reactors, *NUCLEAR nonproliferation, *PLUTONIUM, *NUCLEAR weapons research, *RADIOACTIVE waste management, *URANIUM enrichment
Abstract

Some observers believe that plutonium reprocessing is on the verge of an expansion, while others argue that the end of the practice is in sight. The risk of nuclear proliferation has always been the chief objection to reprocessing but proponents argue that today, with uranium enrichment technology more easily available, reprocessing no longer represents an efficient route toward nuclear weapons. Supporters also tout the energy security that reprocessing could provide to nations without indigenous uranium sources and the reductions in high-level nuclear waste that reprocessing might achieve. Opponents counter that reprocessing offers only marginal benefits in waste reduction and in any event makes little economic sense. Here, Klaus Janberg of Germany (2015), Baldev Raj and P. R. Vasudeva Rao of India, and Hui Zhang of China (2015) debate how nations—taking into account issues ranging from proliferation to waste to cost—should approach plutonium reprocessing.

40. Electrochemical Behaviour of Actinides and Fission Products in Room-Temperature Ionic Liquids

Abstract

In the recent past, room-temperature ionic liquids (RTILs) are being explored for possible applications in nuclear fuel cycle. RTILs are being studied as an alternative to the diluent, n-dodecane (n-DD), in aqueous reprocessing and as possible substitute to high-temperature molten salts in nonaqueous reprocessing applications. This paper deals with the current status of the electrochemical research aimed at the recovery of actinides and fission products using room-temperature ionic liquid as medium. The dissolution of actinide and lanthanide oxides in ionic liquid media and the electrochemical behavior of the resultant solutions are discussed in this paper.
