No. This is a map of estimated antineutrino rates generated from known data.

Data from a theoretical detector that can calculate where its detected neutrinos came from from could be compared to this to find anomalies, but we're not there yet

Probably not, unless the military is hiding some next level tech.

For example, the current generation of detectors, nearly all of which weigh upwards of a ton, have to be placed within tens of meters of a reactor’s core—inside a facility’s fence.
