What Clean Core Thorium Energy does
Clean Core Thorium Energy (CCTE) is a Chicago-based, privately held nuclear fuel technology company founded in 2017 by Mehul Shah. The company has developed a single core product—ANEEL (Advanced Nuclear Energy for Enriched Life) fuel—which combines thorium with High-Assay Low-Enriched Uranium (HALEU) into fuel bundles designed as a drop-in replacement for existing Pressurized Heavy Water Reactors (PHWRs) and CANDU reactors. ANEEL fuel retains the same 19- and 37-element external geometry as conventional bundles, enabling deployment without reactor hardware modifications. In irradiation testing at Idaho National Laboratory's Advanced Test Reactor, ANEEL achieved over 60 GWd/MTU burnup—more than eight times typical discharge burnup of conventional PHWRs and CANDU fuels—while reducing nuclear waste generation by over 85% and enhancing proliferation resistance.
The company operates as a B2B enterprise targeting national and state-owned nuclear power utilities and government nuclear programs, with primary market focus on India's PHWR fleet and Canadian CANDU operators. Clean Core generates no commercial revenue at present; its intended revenue model is licensing and royalty-based supply of ANEEL fuel assemblies to utilities following regulatory qualification. The company has built a multi-jurisdictional partnership ecosystem spanning the US Department of Energy and Idaho National Laboratory for irradiation testing, Canadian Nuclear Laboratories for manufacturing and qualification, Centrus Energy for HALEU supply, and India's NTPC and Larsen & Toubro for deployment in the Indian market. It has secured 10 CFR Part 810 authorization from the US DOE for technology export to India and completed Phase 1 of the Canadian Nuclear Safety Commission's pre-licensing Vendor Design Review with no fundamental barriers identified.
The company is venture-backed, having raised approximately $15.5 million in seed funding in February 2025 from prominent Indian business figures including Sumant Sinha (ReNew), Lakshmi Narayanan (Cognizant), and Deepak Parekh (HDFC Group). NTPC Ltd has been evaluating a minority equity investment. Clean Core maintains a 1-10 person team supported by an advisory board that includes former Atomic Energy Commission of India Chairman Dr. Anil Kakodkar, former CNSC President Dr. Michael Binder, former US NRC Commissioner Jeffrey Merrifield, and former Indian National Security Advisor M.K. Narayanan. The company remains pre-commercial, with next milestones targeting demonstration irradiation in a commercial power reactor and progression through CNSC Phase 2 licensing.

Product offeringCore offering
Clean Core Thorium Energy develops and licenses ANEEL (Advanced Nuclear Energy for Enriched Life) Fuel, a patented thorium-based nuclear fuel that combines thorium with High-Assay Low-Enriched Uranium (HALEU) for use in existing Pressurized Heavy Water Reactors (PHWRs) and CANDU reactors. The fuel achieves over 60 GWd/MTU burnup in irradiation testing, reduces nuclear waste by more than 85%, and matches the existing 19- and 37-element fuel bundle geometry of PHWR and CANDU cores, enabling deployment without reactor hardware modifications.
Product overview
Clean Core Thorium Energy is a nuclear fuel innovation company that has developed a single core product: ANEEL (Advanced Nuclear Energy for Enriched Life) Fuel. ANEEL is a patented thorium-based advanced nuclear fuel that combines thorium with High-Assay Low-Enriched Uranium (HALEU). The fuel is designed as a drop-in replacement for existing Pressurized Heavy Water Reactors (PHWRs) and CANDU reactors, maintaining the same external geometry as current fuel bundles (19- and 37-element designs). ANEEL achieves significantly higher burnup rates (over 60 GWd/MTU, exceeding 8x typical discharge burnup), reduces nuclear spent fuel volumes by over 85%, enhances safety characteristics, and provides proliferation resistance. The company does not offer a modular platform or add-on products; its portfolio centers exclusively on the ANEEL fuel technology.

Clean Core Thorium Energy competitors and assessment
Company assessmentDirect peers
- Lightbridge Corporation: Lightbridge is an advanced nuclear fuel developer designing metallic fuel for existing and new light-water reactors, pursuing a drop-in higher-burnup fuel concept with similar regulatory and utility-adoption dynamics to CCTE's ANEEL.
- X-energy: X-energy develops TRISO-based particle fuel for high-temperature gas-cooled reactors and is pursuing DOE-backed advanced-reactor fuel demonstration, sharing with CCTE the model of a specialized advanced-fuel company moving from R&D to commercial licensing.
- Ultra Safe Nuclear Corporation (USNC): USNC manufactures TRISO fuel (FCR) and develops micro-reactors, positioning it as a peer advanced-fuel developer pursuing qualification pathways and government partnerships analogous to CCTE's DOE/CNSC engagements.
Broad incumbents
- TerraPower: TerraPower is a well-capitalized advanced-nuclear company developing the Natrium reactor with proprietary HALEU fuel, competing for the same advanced-fuel and DOE-partnered ecosystem in which CCTE operates, but at much larger scale and with its own reactor design.
- Framatome: Framatome is a global nuclear fuel and services incumbent supplying fabricated fuel assemblies and fuel-cycle engineering to LWR and research reactors, representing the established competitor CCTE must displace or partner with for commercial fuel deliveries.
- Westinghouse Electric Company: Westinghouse is a major nuclear fuel supplier and reactor OEM with established fuel-fabrication infrastructure, serving as the dominant incumbent whose customers CCTE must win over for PHWR/CANDU fuel business.
- BWX Technologies (BWXT): BWXT manufactures nuclear fuel components and TRISO fuel for US government and commercial programs and operates nuclear fabrication facilities, positioning it as an incumbent advanced-fuel supplier with which CCTE could partner or compete.
- Cameco Corporation: Cameco is a leading uranium producer and nuclear fuel-cycle services provider for CANDU and LWR operators, making it a relevant incumbent peer in the CANDU fuel market that CCTE targets with ANEEL.
Others
- Centrus Energy: Centrus operates the only US-based HALEU enrichment capability and is a strategic MoU partner of CCTE; as the upstream feedstock supplier, it is an adjacent ecosystem participant rather than a direct fuel competitor.
Emerging players
- Terrestrial Energy: Terrestrial Energy is developing an integral molten salt reactor with proprietary fuel and is engaged in parallel CNSC pre-licensing activities, making it a comparable emerging advanced-nuclear technology company pursuing similar regulatory pathways in Canada.
