MUMBAI: In a sheer coincidence, two reactors at BARC in Trombay, which have played a key role in India's nuclear weapon programme, will celebrate their anniversaries-one golden and the other silver- on Saturday.

The 40 mw Indo-Canadian Cirus reactor went critical on July 10, 1960, and the 100 mw Dhruva reactor started functioning on August 8, 1985.
