The correct answer is A) France.
Detailed Analysis of the Agreement
The Historic Visit: During French President Emmanuel Macron's state visit to India in February 2026āwhich marked the elevation of bilateral ties to a Special Global Strategic Partnershipāthe two nations signed an official IndiaāFrance Joint Statement.
The SMR Partnership: A key element of this summit was the formal operationalisation of their shared roadmap regarding Small Modular Reactors (SMRs) and Advanced Modular Reactors (AMRs). This agreement aims to co-develop, procure, and locally manufacture modular clean-energy tech to fast-track India's industrial transition to green energy.
Domestic Policy Alignment: This international tie-up aligns with India's domestic SHANTI Act(Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India), which opens doors for joint-venture and foreign entry into modular civil nuclear construction.
Why the Other Options are Incorrect
ā B) United States: While India-US nuclear discussions continue under general clean energy umbrellas, their regulatory focuses in early 2026 targeted grid trade frameworks rather than a fresh flagship SMR procurement contract.
ā C) Japan: Japan-India civil nuclear treaties are restricted to safety mechanisms and industrial component supplies for heavy-water structures rather than modular reactor deployment.
ā D) Russia: Russia's Rosatom partners with India primarily for large-scale legacy pressurized water reactors (such as Kudankulam) and trilateral setups (Rooppur project in Bangladesh), rather than the newly signed 2026 modular technology transfer pact.
India signed a historic civil nuclear cooperation agreement with which country in February 2026 to procure modular nuclear reactor technologies?
A) France
B) United States
C) Japan
D) Russia
E) Not attempted
The correct answer is B) Mahendragiri, Tamil Nadu.
Key Highlights of the Propulsion Milestone
The Location: The ISRO Propulsion Complex (IPRC) is a world-class test and integration facility located at Mahendragiri in the Tirunelveli district of Tamil Nadu. It is the primary center responsible for assembling, testing, and validating liquid and cryogenic rocket engines for India's launch vehicles.
The Achievement: ISRO successfully concluded a crucial long-duration hot test of its indigenous semi-cryogenic engine at this facility. Unlike conventional liquid engines, this next-generation engine runs on a highly efficient combination of Liquid Oxygen (LOX) and refined Kerosene (Isrosene).
Future Application: This propulsion technology is specifically designed to power the booster stage of India's future heavy-lift rockets, substantially increasing the payload carrying capacity of the LVM3 (Launch Vehicle Mark-3) and next-generation launch vehicles (NGLV).
Why the Other Options are Incorrect
ā A) Sriharikota, Andhra Pradesh: This is the site of the Satish Dhawan Space Centre (SDSC-SHAR), which serves as Indiaās primary spaceport for actual rocket launches and satellite deployments, not engine assembly or hot testing.
ā C) Thumba, Kerala: This is home to the Vikram Sarabhai Space Centre (VSSC), which leads the research, design, and development of rocket systems and launch vehicles but does not handle industrial-scale cryogenic hot testing.
ā D) Bengaluru, Karnataka: This houses ISRO's main headquarters, the U R Rao Satellite Centre (URSC) (satellite manufacturing), and the Liquid Propulsion Systems Centre (LPSC) design labs, but it does not feature open-air, heavy engine firing test stands.
In February 2026, the Indian Space Research Organisation (ISRO) successfully tested its semi-cryogenic engine at the ISRO Propulsion Complex (IPRC). Where is this complex located?
A) Sriharikota, Andhra Pradesh
B) Mahendragiri, Tamil Nadu
C) Thumba, Kerala
D) Bengaluru, Karnataka
E) Not attempted
