Claims

C1strongest claim

For representative assumptions, a 20 kt detector in the Strait of Gibraltar reaches a local benchmark score Z_A ≃2.54 for an assumed 100 MW thermal-power sensitivity-study case in a conservative worst-case transit (with Poisson operating point (P_FA, P_det) ≃ (5.5×10^{-3},0.51) at threshold k=2), while a three-detector line raises the mapped score to Z_A ≃4.66.

C2weakest assumption

The analytic scaling relations and numerical estimates rest on the validity of chosen representative values for detector efficiency, background rates, and submarine reactor power output under real-world conditions, as stated in the abstract for the 'conservative worst-case transit' and 'sensitivity-study case'.

C3one line summary

Antineutrino-based detection can function as a barrier for locating nuclear submarines, with a 20 kt detector achieving Z_A ≈ 2.54 in the Strait of Gibraltar for a 100 MW case and higher scores with multiple detectors.
