Anil Kakodkar: Reactors, Tests, and a Landmark Deal

Anil Kakodkar is an Indian nuclear scientist. He spent his career at the Bhabha Atomic Research Centre (BARC). He later led the Atomic Energy Commission.

Where did he come from?

• He was born on 11 November 1943 in Barwani, Madhya Pradesh.
• His parents were Kamala and Purushottam Kakodkar.
• Both parents were freedom fighters.
• He earned a mechanical engineering degree from VJTI, Mumbai, in 1963.
• He joined BARC in 1964.
• He later earned a master’s degree in stress analysis from the University of Nottingham.

What is the memory hook?

Think “1943 born, 1963 degree, 1964 BARC”. Each year opens a new step.

He played a major part in the Dhruva reactor and in India’s Pokhran tests. These are his best-known technical works.

What is the Dhruva reactor?

• Dhruva is India’s largest nuclear research reactor.
• It first went critical on 8 August 1985.
• Building it took about 10 years.
• Kakodkar was heavily involved in building it.
• He described it as “completely Indian”.
• A research reactor is built for experiments, not for making electricity.

What was his part in the tests?

• He was one of the core architects of the Pokhran test of May 1974.
• He was again a core architect of the Pokhran tests of May 1998.
• He also helped develop India’s PHWR (pressurised heavy water reactor) technology.

What is the memory hook?

Think “Dhruva 1985, tests 1974 and 1998”. The reactor came between the two tests.

He led BARC and then the Atomic Energy Commission (AEC). He also won all three top Padma awards.

What posts did he hold?

• He was Director of BARC from 1996 to 2000.
• He became Chairman of the AEC and Secretary of the Department of Atomic Energy in 2000.
• Srikumar Banerjee took over from him on 30 November 2009.
• He led efforts to revive the reactors at the Madras Atomic Power Station, Kalpakkam, and at Rawatbhata.
• He is now Chancellor of the Homi Bhabha National Institute (HBNI).

Which honours did he receive?

• He received the Padma Shri in 1998.
• He received the Padma Bhushan in 1999.
• He received the Padma Vibhushan in 2009.
• President Pratibha Patil presented the Padma Vibhushan on 31 March 2009.

What is the memory hook?

Think “98, 99, 2009: Shri, Bhushan, Vibhushan”. The honours rise in rank each time.

He said India’s military nuclear work must stay free from outside control. The prime minister backed him.

What happened in Washington in July 2005?

• Manmohan Singh and George Bush were due to meet the next day.
• The Indian team was reviewing the draft of their joint statement.
• Kakodkar objected to the draft.
• Singh said that if Kakodkar said no, India could not go ahead.
• External Affairs Minister Natwar Singh asked him for an acceptable wording.
• Kakodkar scribbled it on a paper napkin.
• The idea was to split civil and military sites.
• All civil sites would come under checks by the International Atomic Energy Agency (IAEA).

What came next?

• In March 2006, talks on the separation plan ran until about 2 a.m. before Bush reached Delhi.
• On 27 July 2007 the government announced the finished 123 Agreement.
• Kakodkar called it “satisfactory” for carrying forward the nuclear programme.
• He also said it was consistent with national policy.
• He later wrote a memoir, Fire and Fury, with Suresh Gangotra.

What is the memory hook?

Think “2005 napkin, 2006 plan, 2007 text”. Each year is one step.

It is India’s long plan to move from uranium to thorium. Kakodkar called it a top task.

What are the three stages?

• Stage 1 uses PHWRs fuelled by natural uranium.
• Stage 2 uses fast reactors that burn the plutonium.
• Their outer layer holds uranium and thorium.
• So they also make more plutonium and uranium-233.
• Stage 3 uses advanced heavy water reactors that burn thorium-plutonium fuel.
• This stage makes more uranium-233 for later use.

What did Kakodkar say in 2008?

• He gave an interview to The Hindu on 20 July 2008.
• He said the three-stage programme “would be implemented unhindered”.
• He also said the timing of thorium needed adjusting.
• The aim was to bridge the demand-supply gap at the earliest.

What is the memory hook?

Think “uranium, plutonium, thorium”. The fuel changes at each step.

He wants India to move to thorium faster. He says India has little good uranium.

What did he say in 2026?

• In a January 2026 interview with IANS, he said the country has limited uranium of the right quality.
• He said newly found resources are still insufficient.
• He said India has abundant thorium.
• He said India should “very quickly transition from uranium to thorium”.
• The government has planned a nuclear mission targeting 100 gigawatts.

What did he add in April 2026?

• He cited the 500 MW Prototype Fast Breeder Reactor as a step towards thorium.
• He said oxide-fuelled reactors double their fuel in about 30 to 35 years.
• He said India is developing metal fuel and fuel recycling to speed this up.

What is the memory hook?

Think “little uranium, lots of thorium”. That is why he wants speed.

Four mix-ups come up again and again. Learn each pair.

What are the traps?

• Research reactor or power reactor? Dhruva is a research reactor. It does not make electricity for the grid.
• Napkin year: The napkin episode was in July 2005. The 123 Agreement text came on 27 July 2007.
• Padma year: His Padma Vibhushan came in 2009. The Padma Bhushan came in 1999.
• Who followed him? Srikumar Banerjee took over the AEC on 30 November 2009.

How do you remember them?

Think “Dhruva research, napkin 2005, Vibhushan 2009”. Match each name to its year.
