101. ASSESSMENT OF MARINE OIL POLLUTION USING KOSMOS-1870 AND ALMAZ-1 RADAR IMAGES

Author

Ivanov, Y.Yu.

Abstract

Radar imagery of sea-surface pollution by oil and surfactants from a synthetic-aperture radar (SAR) from the Kosmos-1870 and Almaz-1 spacecraft is described and analyzed, and a classification based on visual interpretation keys is presented. The possibilities of using a 9.6 cm SAR for monitoring surface pollution, determination of imaging conditions, and keys for identification of oil pollution are discussed. The advantages and limitations of SAR for the monitoring of marine oil spills are demonstrated on the basis of an analysis.

Abstract

The paper provides an assessment of the problem, which presents the management of spent nuclear fuel (SNF) from ship nuclear power units (NPU) in the north-west region of Russia and suggested is a concept of solving the problem. The concept is based on the utilization of the regional underground storage facility for long-term storage of defective, damaged and other kinds of SNF that can not be reprocessed. Presented are the results of the study of operational safety of such SNF storage, including the nuclear and radiation safety, removal of residual heat and protective properties of the rock massif in an emergency scenario.
