Strategic Implications

The deployment of small nuclear reactors may indicate a shift in military energy strategy, potentially strengthening resilience while creating new vulnerabilities. This development could suggest a growing reliance on nuclear power for military operations, which may have significant implications for international humanitarian law and conflict management.

What Happened

Energy Resilience Meets Military Vulnerability

The use of small nuclear reactors in future conflicts may pose significant challenges for military energy resilience and international humanitarian law. The US Army has launched Project Janus, a programme providing up to $2.2 billion in milestone-based funding for military microreactors, while the European Commission has adopted its first dedicated SMR strategy. However, the protection of nuclear electrical generating stations under international humanitarian law may not be sufficient to prevent radiological incidents, as demonstrated by the war in Ukraine. This development was first reported by Unknown Source.
