The national policies of the U.S., Norway, and Russia have converged to address this risk through the Arctic Military Environmental Cooperation (AMEC) initiative. This paper discusses joint activities on solid radioactive waste (SRW) storage technologies in the Arctic for the Russian Navy. These are Western as well as Russian developments and will facilitate meeting Russia’s needs for storing solid radioactive waste from decommissioned nuclear submarines. All work is directed at applications at Andreeva Bay or other SRW management sites in northwest Russia. Andreeva Bay is the Navy site with the largest inventory of SRW, and the Russian Navy has recently completed construction of an SRW storage facility at this site. The technologies which have been selected so far are 1) a coating for concrete and metal, 2) containers for waste storage and transportation, and 3) various materials used i...

The existing SRW storage site at this shipyard is filled to capacity, which is forcing the shipyard to reduce its submarine dismantlement activities. The Polyarninsky Shipyard Waste Management Installation is planned as a combination of several AMEC projects. It will have several elements, including a set of hydraulic metal cutting tools, containers for transport and storage, the Mobile Pretreatment Facility (MPF) for Solid Radioactive Waste, the PICASSO system for radiation monitoring, and a Waste Storage Facility. Hydraulically operated cutting tools can cut many metal items via shearing so that dusts or particulates are not generated. The AMEC Program procured a cutting tool system, consisting of a motor and hydraulic pumping unit, a 38-m...

Inadequate management of this waste poses a substantial threat for pollution of the fragile Arctic environment. The Arctic Military Environmental Cooperation (AMEC) Project 1.3 has assessed waste treatment options, selected technologies, and is now designing and constructing a comprehensive SRW pretreatment system to meet this problem (1). The chosen approach is to design, construct and deploy a novel Mobile SRW Pretreatment Facility (MPF). A key feature of the concept is the mobility aspect, which allows the system to be readily transported between the various shipyards and intermediate SRW storage sites on Russia’s Kola Peninsula and in Severodvinsk. These sites either currently store or will generate the majority of the SRW in the region. Much of the existing waste storage is in poor condition. Based...

This paper discusses joint activities over the past year among Norwegian, Russian, and U.S. technical experts on solid radioactive waste storage technologies in the Arctic for the Russian Navy. These are Western as well as Russian developments and will facilitate meeting the Russian Navy's needs for storing solid radioactive waste from decommissioned nuclear submarines. The first batch of multiple- use steel containers for transportation and storage of solid radioactive waste have been fabricated at a Russian shipyard and work on the second batch is in process. The partners are also working on single- use concrete containers for transportation and long-term storage, lightweight modular storage buildings, and Russian-made radiation monitoring equipment for use in waste storage facilities. ...

We discuss its foundations and some corrections to scaling which must be taken into account for an adequate estimation of H. Using this method, we analyze a set of artificially generated curves with known Hurst exponent and compare the result with Fourier analysis. We also discuss the case where the surface to be analyzed has a curved bias with a maximum or minimum. In this case, the relation between the scaling exponents associated with the first-return histograms and the Hurst exponent H is different from the unbiased case.
