Nature published a dedicated report examining the history and commercial development of nuclear energy, detailing the sector's shift from early post-war projections to modern reactor designs and fusion efforts. The journal released the supplement on August 26, 2026.
Nuclear fission releases energy by splitting a heavy atomic nucleus into smaller fragments. Within seven years of its discovery, the United States used the process to destroy two Japanese cities. Less than ten years after those bombings, proponents promoted nuclear fission as a peaceful electricity source, projecting it would be plentiful and inexpensive enough that consumers would not pay for what they used. The journal noted that this outcome did not occur.
The supplement reviews current technical and policy challenges across fission and fusion technology, covering several distinct areas of development:
- Smaller reactor designs intended to fulfill long-standing power generation goals.
- Technical efforts to address nuclear waste disposal and assessments of historical waste management.
- Public safety debates regarding pro-nuclear politics.
- The engineering of nuclear reactors designed for road transport.
- Commercial fusion initiatives, noting that 46 companies are competing to commercialize fusion for energy.
- Methods for using nuclear waste to power space exploration missions.
Nuclear firm Oklo Inc. provided financial support for the supplement. Nature maintained full editorial independence across all editorial decisions related to the published content.
