The two reactors at Dominion Energy’s Surry plant are among the oldest in the U.S. nuclear fleet. Yet when the plant celebrated its 50th anniversary in 2023, staff could raise a toast to the future. Surry was one of the first plants to file a subsequent license renewal (SLR) application, and in May 2021, it became official: the plant was licensed to operate for a full 80 years, extending its reactors’ lifespans into 2052 and 2053.

Report: Funding growth for private fusion companies

December 5, 2025, 12:02PMNuclear News

A new report from the F4E Fusion Observatory highlights the robust growth of investments in private companies that are developing fusion energy technologies. The report, Global Investment in the Private Fusion Sector, is an updated release of a previous F4E Fusion Observatory report, published “in response to the unprecedented acceleration of investments in fusion companies since June 2025, which are consolidating fusion as a fast-growing emerging market.”

Global funding: According to the report, the cumulative global funding in private fusion companies between June and September 2025 increased from €9.9 billion to €13 billion (about $11.6 billion to $15.17 billion). Funding for the private fusion sector in September was more than eight times greater than in 2020. The report also identifies 77 companies that are in the “fusion private ecosystem.”

Here is a recap of recent industry happenings:

ADVANCED REACTOR MARKETPLACE

Agreement signed on advanced nuclear technology in space

Texas-based space technology and orbital logistics developer Space Ocean Corporation and New Mexico–­based space nuclear power systems developer Space Nuclear Power Corporation (SpaceNukes) have signed a letter of intent to explore the integration of advanced nuclear reactor technology into future space missions. Space Ocean agreed to test SpaceNukes’ 10-kilowatt microreactor aboard its ALV-N satellite and, if performance criteria are met, to use SpaceNukes as a core supplier of reactors for future Space Ocean lunar and planetary missions. The companies also agreed to examine the integration of fluid delivery systems with reactor modules, to collect operational data to support technology readiness certification, and to form a joint working group to pursue additional space infrastructure and commercial opportunities.
