NASA's Ambitious Lunar Nuclear Reactor Project
The American space agency NASA has announced plans to establish a 100-kilowatt nuclear reactor on the Moon by 2030. This project is part of the Artemis Program and its primary objective is to establish long-term human presence on the Moon.
NASA's Acting Administrator Sean Duffy has directed to accelerate this project, which has been upgraded from the original 40-kilowatt plan to now 100 kilowatts. This reactor will be based on Fission Surface Power System and will be capable of operating for at least 10 years.
Need for Nuclear Energy on the Moon
Challenging Lunar Environment
The energy problem on the Moon is related to the unavailability of sunlight. On the Moon, both one day and one night are equivalent to approximately 14 Earth days each. During this period, temperatures drop to -200 degrees Celsius and solar panels become ineffective.
Advantages of Nuclear Energy
Continuous energy supply: 24x7 power generation, regardless of weather or location
High capacity: 100-kilowatt capacity, which can power approximately 80 homes on Earth
Compact design: Low weight and size, ideal for space missions
Long-term operation: At least 10 years of operational period
International Space Competition
China-Russia Plans
China and Russia have jointly planned to establish an automated nuclear power plant on the Moon by 2035. Both countries are collaborating on building the International Lunar Research Station.
China's goal is to send its first astronaut to the Moon by 2030, while the American Artemis mission is facing delays.
India-Japan Initiative
India and Japan are collaborating on the Chandrayaan-5 (LUPEX) mission, which will be launched in 2027-28. This mission is focused on searching for water and ice at the Moon's south pole.
Legal and Geopolitical Implications
Outer Space Treaty (1967)
According to the 1967 Outer Space Treaty, no country can claim ownership of the Moon. However, countries establishing nuclear reactors can effectively create security zones, which would limit other countries' access.
Artemis Accords
The Artemis Accords signed by 56+ countries include the concept of "safety zones" that emphasize transparency and peaceful use.
Technical Challenges and Safety Measures
Major Technical Obstacles
Extreme temperature variation: Above 100°C during day, down to -200°C at night
Low gravity: 1/6th gravity compared to Earth
No atmosphere: Lack of natural protection
Radiation risk: In case of accidents during launch
Safety Measures
NASA is planning to send the reactor in an inactive state to minimize radiation risk during launch. Additionally, a Brayton cycle power conversion system will be used.
India's Nuclear Energy Policy
India has announced ₹20,000 crore in the 2025 budget for the development of Small Modular Reactors (SMRs). The country's goal is to achieve 100 GW nuclear capacity by 2047.
Currently, India's installed nuclear capacity is 8,180 MW, which is to be increased to 22,480 MW by 2031-32.
