New Delhi, June 20 : First two units at India’s oldest nuclear power plant, Tarapur Atomic Power Station— world’s oldest operating nuclear units — have been reconnected to the grid following extensive modernisation and refurbishment, a new report has said, citing Nuclear Power Corporation of India Limited (NPCIL).
The report from World Nuclear News said Tarapur units 1 and 2, boiling water reactor (BWR) units commissioned in 1969, were downrated from 200 MWe to 160 MWe (gross) and had been offline since 2020 for major refurbishment work. NPCIL called the restart of both units as “a major milestone in India’s nuclear power program,” adding that the achievement reaffirms the enduring legacy of India’s first nuclear power station and reflects the dedication and technical expertise of Team NPCIL. The Atomic Energy Regulatory Board (AERB) approved the operational resumption of unit 2 on May 7 after NPCIL completed refurbishment activities. The refurbishment included the complete replacement of reactor coolant recirculation piping with forged piping and fittings made of advanced corrosion-resistant stainless steel,” the regulator said.
