The principle behind applying this research towards homeland security is well-known, and the DoD actually have backed a neutrino detector dedicated to non-proliferation and monitoring called "Watchman".

Interestingly, OP is correct in that the American has no interest or influence on the experiment in the article. In fact, the SNO+ experiment (backed primarily by Canada and the UK) is actively competing with other upcoming American-led experiments backed by the DOE and DOD.
