"Pure Water at SNO+ Detects Distant Fission Reactor Anti-Neutrinos"
The SNO+ neutrino detector project has shown that it can detect anti-neutrinos originating from nuclear fission reactors over 240 kilometers away, including Canadian CANDU and US LWR types. The low detection threshold of the SNO+ detector, even in its incomplete state, has made this possible. The focus of SNO+ on nearby nuclear fission reactors is due to the constant beta decay that occurs in their nuclear fuel, which produces electron anti-neutrinos in a predictable manner.
