Energy#
The global nuclear energy sector is experiencing renewed momentum in 2026, though challenges remain. According to the World Nuclear Report, there are currently 404 nuclear power reactors operating worldwide—five fewer than a year earlier and 34 less than the historic peak of 438 in 2002. Only four new power reactors were connected to grids in the past year, adding 4.4 GW of capacity.
Despite the 25-year pattern of stagnation, optimism persists. The World Nuclear Association projects that global nuclear capacity could reach 1,446 GW by 2050 if governments meet their national targets, far exceeding the 1,200 GW goal set in the Declaration to Triple Nuclear Energy. However, several national targets, including the United States' ambitious 400 GW goal, "rely heavily on an expansion of nuclear capacity where there is currently little or no ongoing construction."
Taiwan closed its last reactor in May 2025, reducing the number of countries operating nuclear power plants to 31. Meanwhile, the industry continues to advocate for nuclear's role in providing stable, low-carbon baseload power for data centers and AI operations, with major technology companies making strategic investments in nuclear energy.

Research Initiatives: The industry continues exploring nuclear energy for hydrogen production and industrial decarbonization, enhancing nuclear's potential role in broader emissions reduction strategies.
Defense#
Nuclear security and non-proliferation face significant challenges in 2026:
New START Expiration#
February 5, 2026 marked the expiration of New START—the last remaining legally binding nuclear arms control treaty between the United States and Russia. This represents a critical turning point in global nuclear security.
Eroding Arms Control: The year 2026 arrives with "looming threats of nuclear weapon employment more than ever," according to security analysts, as the world faces eroding arms control frameworks.
US Nonproliferation Policy Gap: Critics note that the Trump administration's National Defense Strategy failed to mention nuclear weapons proliferation, raising concerns about US commitment to nonproliferation efforts.
Iran Nuclear Talks: Iran has requested changes to the venue and format of nuclear talks with the US, adding uncertainty to already complex negotiations.
Nuclear-Powered Submarines: A new era of nuclear-powered submarines is creating tensions in nuclear-weapon-free zones, particularly with AUKUS developments.
Market: Uranium Spot Price#
The uranium market is experiencing significant activity in early 2026:
Price Movement#
- January 2026 Rally: Uranium spot prices surged approximately 25% in January, briefly exceeding $100 per pound—the highest levels in years.
- Current Levels: After the sharp rally, uranium prices have steadied near $90 per pound following a corrective pullback.
- Supply Crunch: The surge is driven by supply constraints combined with rising demand from expanding nuclear programs.
Market Drivers#
- Supply Constraints: Mine closures and production challenges in key uranium-producing nations continue to limit supply.
- Rising Demand: Countries expanding nuclear capacities, particularly in Asia and the Middle East, are increasing procurement.
