# Indira Gandhi Centre for Atomic Research

Indira Gandhi Centre for Atomic Research (IGCAR) is one of India's premier nuclear research centres. It is the second largest establishment of the Department of Atomic Energy (DAE), next to Bhabha Atomic Research Centre (BARC), located at Kalpakkam, 80 km south of Chennai, India. It was established in 1971 as an exclusive centre dedicated to the pursuit of fast reactor science and technology, due to the vision of Vikram Sarabhai. Originally, it was called Reactor Research Centre (RRC). It was renamed to Indira Gandhi Centre for Atomic Research (IGCAR) by the then Prime Minister of India Rajiv Gandhi in December 1985. The centre is engaged in broad-based multidisciplinary programme of scientific research and advanced engineering directed towards the development of fast breeder reactor technology in India.

## History

The fast reactor related research in India, originated at BARC, Mumbai. Later, RRC was established at Kalpakkam with the same mandate. The Central Workshop, Safety Research Laboratory and Materials Sciences Laboratory were constructed in 1975–1976. Soon, the Radio-Chemistry Lab and Electronics and Instrumentation Lab were constructed.
The center houses a Fast Breeder Test Reactor (FBTR), which attained its first criticality in October 1985.
A few years later, in 1994, SQUID, ASIC and Diamond Anvil Cells were developed. In the same year, High-Power Physics and Engineering Experiments were undertaken in the FBTR.
In 1996, KAMINI reactor reached criticality. State-of-the-art Neutronic Channels were commissioned for FBTR in 1999.
A Boron-Enrichment Plant was commissioned in April 2001.
A BARC Training School was started in 2006. In 2009, FBTR was operated at a maximum power level of 18.6 MWt with 55 sub-assemblies for 1732 hours.

## Commercial reactors

The facility houses two PHWRs that generate 220MWe each that operate for commercial purposes. These are managed independently by the Nuclear Power Corporation of India.

## Research reactors

There are three research reactors at IGCAR.
* FBTR is a liquid metal cooled fast breeder test reactor, maintained by Reactor Operation and Maintenance Group (ROMG).
* KAMINI 30 kWt reactor, starred in 1996, uses Uranium 233 fuel transformed from Thorium in the FBTR.
* Prototype Fast Breeder Reactor, a 500MWe fast breeder reactor using Mixed Oxide (Uranium oxide + Plutonium oxide) fuel based on the Sodium-cooled fast reactor design.
In addition, the Research Facility also built the 100MWe reactor for India's first nuclear submarine the Arihant class submarine project and operated it on land for testing purposes since it attained criticality in December 2004. The submarine launched on 26 July 2009 has this reactor.

## Reprocessing plant

The Kalpakkam Atomic Reprocessing Plant [KARP] facility has been estimated to have a capacity to reprocess 100 tonnes of spent fuel plutonium per annum. It incorporates a number of innovative features such as hybrid maintenance concept in hot cells using servo-manipulators and engineered provisions for extending the life of the plant. This plant will cater to the needs of reprocessing fuels from MAPS as well as FBTR. It has mastered the technology of reprocessing highly irradiated mixed carbide fuel for the first time in the world.

## Fast reactor fuel reprocessing at IGCAR

Reprocessing Development Laboratory was designed in early seventies and the commissioning of inactive facilities was carried out in 1976. The plutonium handling facilities were cleared for operation in 1980. The reprocessing of irradiated thorium rods which was carried out during the period 1989 to 1992 in the concrete shielded cells, was the first major radioactive operation. The U-233 recovered during the operation was used in fabricating the fuel for the KAlpakkam MINI reactor (KAMINI). U-233 was also useful for the fuel development programme for carrying out the Prototype Fast Breeder Reactor test fuel irradiation experiments in Fast Breeder Test Reactor. Apart from this, the operation aided in validating the equipment and design of system as well as the manpower training. Later a hot cell facility for reprocessing of Fast Breeder Test Reactor fuel was conceived which had the necessary features for delivering the product with all the uncertainties in the dissolution of irradiated fuel and process flowsheet. Added to this was the need for the deployment of the yet to be proven designs of centrifuge and centrifugal extractors without which the success of the PUREX process for fast reactor fuel reprocessing would be doubtful. With these minimal inputs, the hot cell facility, Lead Mini Cell (LMC) was created, which was later rechristened as CORAL (COmpact 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.

## Collaborations

The interaction with IIT-M started in 1995 through two collaborative projects, which were initiated with late Dr. R.S. Alwar, eminent professor in Applied Mechanics. The first project was on simulation of thermal shock on the control plug mockup and the second was on simulation of thermal striping in the core structure. An MoU was established on 19 July 1997 for the formation of ‘IGCAR- IITM Cell’ with Prof. R. Natarajan (then Director, IIT-M) as chairman and late Dr. Placid Rodriguez as co-chairman. Prof. K.V.S. Rama Rao was Dean, ICSR during that period. In the first cell meeting held on 26 February 1997, seven projects were identified. Based on the decisions taken in the meeting, four projects with a funding to the tune of eighty eight lakhs were sanctioned. In the past thirteen years, twenty five meetings of the IGCAR-IITM cell have been conducted. Already twenty nine projects have been completed with the funds to the tune of 40.5 million and fifteen projects are in progress with a funding of 34 million.
Indira Gandhi Centre for Atomic Research, Kalpakkam, has entered into a collaboration with the IIT Kharagpur to carry out research related to the design and development of Fast Breeder Reactors (FBRs). A dedicated IGCAR-IITKGP R&D cell has been set up in the premises of IIT Kharagpur under the Advanced Technology Development Centre's Structural Reliability Research Facility of IIT KGP.
