Will the U.S. Nuclear Regulatory Commission (NRC) issue a Final Safety Evaluation Report (FSER) for any new SMR design by April 1, 2026?

DescriptionThis event resolves based on whether the U.S. Nuclear Regulatory Commission (NRC) issues a Final Safety Evaluation Report (FSER) for any new Small Modular Reactor (SMR) or advanced reactor design on or before April 1, 2026. This follows the landmark December 2, 2025, FSER issuance for TerraPower’s Natrium design, which signaled a new, expedited regulatory environment.
-
- For a positive resolution, the NRC must publish a formal FSER for a Standard Design Approval (SDA) or Design Certification (DC) for a design that had not received an FSER prior to December 3, 2025. This specifically excludes the already-approved designs from NuScale (VOYGR). The issuance of a "Safety Evaluation Report with Open Items" or a "Preliminary Safety Evaluation" does not qualify. The report must be final and published on the official NRC website.

- The market is driven by the race between Oklo (Aurora Powerhouse) and X-energy (Xe-100). Oklo’s accelerated review timeline, supported by Sam Altman and the Department of Energy’s December 2025 safety approvals for its fuel fabrication facility, suggests a high probability of an early 2026 NRC milestone. However, historical delays in "first-of-a-kind" liquid-metal or gas-cooled reactor reviews provide the 50/50 balance for traders.
-
- Primary resolution sources are the official NRC newsroom and the NRC’s advanced reactor dashboard (nrc.gov). Secondary verification will be provided by official company press releases from the developers.

- This event measures the regulatory momentum of the second wave of advanced nuclear technology in the United States.
