India's Gorakhpur slated for 2031 operation

Gorakhpur, in the Fatehabad district of Haryana, is earmarked for the construction of four Indian-designed 700 MWe pressurised heavy water reactors (PHWRs) to be built in two phases. India's Atomic Energy Regulatory Board (AERB) granted a siting licence in 2015, and approved the start of excavation work for the construction of the first two units as long ago as 2018 - several years after an official groundbreaking ceremony had been held.

At that time, first concrete had been expected to be poured for unit 1 in 2019, with construction expected to take five and a half years. Consent for the pouring of first concrete was given by the AERB in 2020.

According to the Press Trust of India, the minister visited the site on 14 July "to review the progress of the nuclear power project being implemented by the Nuclear Power Corporation of India Limited (NPCIL) under the Department of Atomic Energy" and confirmed that the first pour of concrete for unit 1 is targeted "by October 2025". First criticality is targeted by June 2030 and commercial operation by March 2031. Unit 2 is expected to follow "with a 6-month gap from Unit 1".

The Indian government already classes Gorakhpur 1 and 2 as "under construction", although the International Atomic Energy Agency's PRIS database does not consider a reactor to be under construction until the first major placing of concrete for the base mat of the reactor building is made.

The second phase at Gorakhpur - units 3 and 4 - are amongst ten units that the Indian government has sanctioned to be built under a "fleet" approach: the others are Mahi Banswara units 1-4 (in Rajasthan), Kaiga units 5 and 6 (in Karnataka), Gorakhpur units 3 and 4 (Haryana), and Chutka units 1 and 2 (Madhyar Pradesh).

India currently has 24 operable nuclear energy reactors with a total installed capacity of 8.88 GW, with six units - totalling 4,768 MWe - under construction. The country is targeting an aiming to increase its nuclear energy capacity to 100 GW by 2047.
