LLNL, Ampera partner to develop thorium-based TRISO fuel
Lawrence Livermore National Laboratory has formed a strategic partnership with Ampera to develop the company’s nuclear fuel concept through a project named THUNDER, for Thorium Unimodal Droplet Ejection for Reactors.
The focus of THUNDER is fabricating TRISO made with kernels of thorium rather than the usual uranium. LLNL and Ampera will evaluate and optimize liquid metal–jetting technology to produce highly uniform, spherical kernels of thorium-232 for later processing into TRISO fuel.

Radioactive effluents and concentrations expected from the Clinch River Breeder Reactor (CRBR) during normal operation have been assessed. Developed were the individual off-site dose values as well as population doses within an 80-km (50-mile) radius of the proposed facility. Comparison has been with the as low as reasonably achievable (ALARA) exposure objective as in 10CFR50, Appendix I, of the Code of Federal Regulations. All estimated releases are well within the concentration limits found in 10CFR20. The calculated doses to individuals are consistently lower than values of 10CFR50, Appendix I. Population exposures are a very small fraction of that due to background radiation. Exposures due to CRBR effluents are also in conformity with cost-benefit arguments of the ALARA objective. Measures are in place to follow the design progression and operation of the facility to retain the ALARA aspect of the doses associated with the effluent releases.
