  The Neutron Activation Analysis (NAA) plays an exceptional role in the modern
nuclear engineering, especially in detection of hazardous substances. However,
in the aquatic environment, there are still many problems to be solved for
effective usage of this technique. We present status of SABAT (Stoichiometry
Analysis By Activation Techniques), one of the projects aiming at construction
of an underwater device for non-invasive threat detection based on the NAA.
