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.
The American Nuclear Society (ANS) Standards Board shall be responsible for policy and procedural direction for the standards activities of the Society. The Standards Board oversees the activities of the Standards Committee. The Standards Committee is a historical term that is used to identify professionals who participate in various committees allocated by the Standards Board. The Standards Committee does not conduct itself as a committee. It does not meet nor act as a single body. It is simply a collection of qualified volunteers who participate in the development and maintenance of ANS consensus standards and related documents.
The Standards Committee is responsible for the development and maintenance of standards that address the design, analysis, and operation of components, systems, and facilities related to the application of nuclear science and technology. The scope includes the development and maintenance of standards on the following subjects and closely related activities:
The Standards Committee does not develop standards for the application of radiation for medical purposes. The Standards Committee may review standards being developed or issued by other organizations on related topics to help ensure consistency and completeness and to avoid duplication. Standards developed by the Standards Committee are intended to be issued as American National Standards.
