How chemistry helps track and detect nuclear materials

Monitoring the use of nuclear materials is an issue of global concern, especially amid news that the United States is leaving the Joint Comprehensive Plan of Action (commonly known as the Iran nuclear deal), an agreement intended to limit that country’s nuclear program. But the same materials needed to build nuclear weapons also show up in power plants. So how can international regulators ensure nuclear materials are used only for peaceful purposes? Chemists are helping to develop techniques to spot illicit nuclear activity from afar and track it when it slips out of regulatory control. For example, a massive antineutrino detector called Watchman could be a powerful tool to keep tabs on distant nuclear operations—if scientists can get the chemistry right.
