Atomic Canyon partners with INL on AI benchmarks
As interest and investment grows around AI applications in nuclear power plants, there remains a gap in standardized benchmarks that can quantitatively compare and measure the quality and reliability of new products.
Nuclear-tailored AI developer Atomic Canyon is moving to fill that gap by entering into a new strategic partnership with Idaho National Laboratory to develop and release the “first comprehensive benchmark suite for evaluating retrieval-augmented generation (RAG) and large language models (LLMs) in nuclear applications.”

The High-Temperature Engineering Test Reactor (HTTR) is a 30-MW(thermal) helium gas-cooled reactor that uses a prismatic block. The core bottom structure (CBS) of the HTTR consists of an arrangement of graphite components, and it supports the core elements within the reactor vessel. Vibration tests are performed with two scale models to clarify the seismic response of the CBS. The vibration characteristics of the CBS are clarified quantitatively, and the structural integrity of the graphite components is confirmed.
