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.

A study on considerations and strategies for developing safety goals applicable to all nuclear facilities is presented. A scheme of basic safety goals and subsidiary safety goals is assumed, and quantitative basic safety goals for radiation protection of individuals in the vicinity of nuclear facilities are discussed. The risk limit rules are based on comparative risk factors for various health effects, including annual dose, health detriments, acute fatality, latent cancers, and severe hereditary effects. The comparative factor of 1% is used for nonfatal health detriments and 0.1% for fatal effects. A risk limit profile is generated from the risk factors, biological effects, and statistics of injury and mortality rates from general causes. The approaches have potential for developing integrated and comprehensive safety goals.
