“

The Fast Breeder Test Reactor he commissioned at Kalpakkam reached criticality in 1985 under his directorship, a rare technical feat in India at the time.

The Story

1
In 1952, C. V. Sundaram earned his doctoral degree from the Indian Institute of Science under metallurgist Brahm Prakash, setting the stage for his career in chemical metallurgy.
2
⚙️ By 1956, Sundaram joined the Department of Atomic Energy and took charge of producing refractory metals like zirconium and tantalum, critical for India's nuclear ambitions.
3In 1975, he led the metallurgy department at Bhabha Atomic Research Centre before becoming director of Indira Gandhi Centre for Atomic Research in 1982, where he pushed forward the Fast Breeder Test Reactor project.
4⚡ Under his directorship, the Fast Breeder Test Reactor at Kalpakkam achieved criticality in 1985, marking a pivotal milestone in India's nuclear reactor technology.
