AUTOMATED RADIOLOGICAL MONITORING AT A RUSSIAN MINISTRY OFDEFENCE NAVAL SITE

摘要

The Arctic Military Environmental Cooperation (AMEC) Program is a cooperative effort between thernmilitary establishments of the Kingdom of Norway, the Russian Federation, and the United States. Thisrnpaper discusses joint activities conducted over the past year among Norwegian, Russian, and U.S.rntechnical experts on a project to develop, demonstrate and implement automated radiologicalrnmonitoring at Russian Navy facilities engaged in the dismantlement of nuclear-powered strategic ballisticrnmissile launching submarines. Radiological monitoring is needed at these facilities to help protectrnworkers engaged in the dismantlement program and the public living within the footprint of routine andrnaccidental radiation exposure areas. By providing remote stand-alone monitoring, the Russian Navy willrnachieve added protection due to the defense-in-depth strategy afforded by local (at the site), regionalrn(Kola) and national-level (Moscow) oversight. The system being implemented at the PolyarninskyrnRussian Naval Shipyard was developed from a working model tested at the Russian Institute forrnNuclear Safety, Moscow, Russia. It includes Russian manufactured terrestrial and underwater gammarndetectors, smart controllers for graded sampling, radio-modems for offsite transmission of the data, andrna data fusion/display system. The data fusion/display system is derived from the Norwegian PicassornAMEC Environmental Monitoring software package. This computer package allows monitoringrnpersonnel to review the real-time and historical status of monitoring at specific sites and objects and tornestablish new monitoring protocols as required, for example, in an off-normal accident situation. Plansrnare being developed to implement the use of this system at most RF Naval sites handling spent nuclearrnfuel.
