Russia plans a 10-kilowatt nuclear reactor for the International Lunar Research Station (ILRS), a joint Russia-China lunar programme targeted for the 2030s. The proposal appears within a broader US-China-Russia competition to deploy fission power on the Moon, where permanently shadowed regions and long lunar nights make solar power alone unreliable.
A 10-kilowatt reactor could provide continuous electricity for habitat life support, thermal control, communications, computing, drilling, and volatile processing, independent of sunlight. Its radioactive materials, launch-failure consequences, thermal rejection systems, and potential interference with sensitive instruments would require defined exclusion or “keep-out” zones; concentrated nuclear infrastructure could also create strategic chokepoints and increase conflict risk around scarce lunar resources.
The Ark team should track ILRS reactor milestones, launch dates, reactor mass and fuel configuration, power-conversion and heat-rejection designs, emergency-shutdown provisions, and proposed keep-out radii. Ark site planning should reserve geographically separated power and archive nodes, model contamination and debris scenarios, and develop interoperability standards that preserve access across competing US, Chinese, and Russian lunar operational zones.
