Thorcon’s design has undergone extensive independent evaluations, consistently earning positive assessments that set it apart from conventional nuclear power plants. 

Early reviews by Pacific Northwest National Lab (2012) confirmed the reactor’s criticality and stability. Further simulations by Milano Multiphysics validated burn rates, leading them to join the design team. 

Argonne National Lab (2017) used its advanced simulation tools to analyze Thorcon’s reactor neutronics, and confirmed the accuracy of Thorcon’s calculations.

Leading nuclear engineering firms, Empresarios Agrupados and Bureau Veritas, initially engaged as independent evaluators but later became partners due to their confidence in the design. 

Governmental evaluations in Indonesia have further reinforced Thorcon’s credibility. Key studies include the National Economic and Industry Committee (2017), an Office of the President-led supply chain review (2018), and year-long positive assessments by P3Tek (2019) and PLN-Engineering (2021). 

Based on these findings, Indonesia’s National Energy Council incorporated Thorcon’s demonstration plant into its next five-year plan.

Regulatory progress has also been significant. 

Indonesia’s nuclear regulator, Bapeten, spent three years evaluating Thorcon’s design which led to a pre-licensing agreement in 2023. 

When Thorcon formally entered the licensing process with Bapeten in February 2025, BAPETEN Deputy Chairman, Haendra Subekti, expressed appreciation for
Thorcon’s proactive approach to safety and security. “We recognize and appreciate the efforts of PT Thorcon Power Indonesia for their proactive consultations within the 3S (Safety, Security, Safeguards) framework,” Subekti said. “This approach ensures that all safety and security aspects are addressed and will help minimize technical and administrative obstacles as the licensing process continues.”

Thorcon stands out due to its rigorous validation, international partnerships, and governmental support, positioning it as a superior, well-vetted alternative to traditional nuclear power plants.
