[.Scott]

TL;DR Summary

The SNO+ Experiment in Canada is still in development, but analysis of early antineutrino detections are believed to be from appear to be the from Ontario reactors 240Km away.

The SNO+ Experiment in Canada is still in development, but analysis of early antineutrino detections as published in Physics Review Letters and as referenced in the SNO+ results page are believed to be from appear to be the from Ontario reactors 240Km away.

SNO+ may be in development, but SNO already produced a Nobel.

This is news, but not new. Kamland has done this, and there are multiple groups looking at more portable devices to do nuclear non-proliferation: drive up to the site boundary and measure whether the core is, e.g. breeding plutonium when it shouldn't be..
