Engineers Develop More Accurate AI Algorithm for Improving Nuclear Reactor Performance

To expand the availability of electricity generated from nuclear power, several countries have started developing designs for small modular reactors (SMRs), which could take less time and money to construct compared to existing reactors. Toward this effort, a Purdue University study has made progress in enabling artificial intelligence to improve monitoring and control of SMRs. Read on to learn what this means.
