Methodology and techniques of early detection anomalies

Assessment of the future radioactive environmental contamination threat by releases from dumped submarine and ship reactors with Spent Nuclear Fuel (SNF) is a project goal. The methodology of detection of traces of 85Kr and 3H (which the first are leaking from the SNF) in sea water is advanced. Search of ship nuclear reactors on a bottom in dumpsites on 85K plume is proposed. Investigation of releases from the dumped ship reactors with SNF of icebreaker “Lenin" in Kara Sea is launched (September 2003). Research has complex character: experiments with SNF, creation of techniques located on R/V “Ak. B. Petrov" and expedition works. Preliminary observation of hydrological characteristics in zone of marked dumpsites has been fulfilled. The first results on the 85Kr concentration in near-bottom layer of Kara and the Barents Seas also Tritium and Radiocesium during August 2003 were obtained
