“…Radioactive waste is generated throughout the nuclear cycle and accidental discharges, and 70 years of nuclear activities have resulted in a significant legacy of contaminated soil and sediment at nuclear facilities worldwide (McKenzie and Armstrong-Pope, 2010;Reistad et al, 2008;Zachara et al, 2013). Due to their need for cooling water several nuclear facilities (example.g.…”

In the UK, several coastal nuclear sites have been identified as vulnerable to future sea level rise. Legacy contamination at these sites has accumulated in sub-surface sediments at risk of future seawater inundation and intrusion. Porewater salinization, changes in pH and the influx of oxygen into sediments may impact the stability of sediment associated uranium (U). In this study, saturated column experiments were performed to compare the mobilisation of U from oxic and reduced sediments into seawater under environmentally relevant flow conditions. Uranium release profiles were independent of the initial geochemistry of the sediments. Uranium release from the sediments was kinetically controlled, showing relatively slow Highlights • Seawater intrusion promotes U mobilisation from oxic and reduced sediments • Initially reducing conditions result in stronger binding of U to the sediment • Mobilisation was pH dependent and kinetically controlled • Fe(III) phases formed during Fe(II) oxidation retard U release temporarily

“…The territory of the temporary storage site for radwastes in Guba Andreeva, which is now in the reconstruction stage, was contaminated as a result of the leakage of liquid radwastes and spills of solid radwastes as a result of impairment of the seal tightness of the packaging [1][2][3]. In this connection, the surrounding space and sea area were contaminated as a result of the transport of dust and fresh-water runoff.…”

“…The territory of the temporary waste storage site abounds with boggy sections in the anticlines of the relief at different hypsometric levels with surface and subterranean fl ows through water-bearing levels [2]. The Guba Zapadnaya Litsa opens into the Motovskii Zaliv of the Barents Sea and is navigable year round owing to warming by branches of the Murmansk coastal stream [7].…”

“…Radioecological state of the soil cover and marine environment. The operation of the temporary storage site in Guba Andreeva for more than 40 years has led to fragmentary contamination of the soil cover and deeper layers of soil as a consequence of spills and leakage during handling of solid and liquid wastes [2,3]. Therefore, for the surrounding territory it can be regarded as a source of contamination risk due to radionuclides.…”

Il'in, I. S. Usyagina, UDC 632.15(470.21+268.45) and N. E. Kasatkina The effect of a radiologically hazardous object -a temporary storage site for radioactive wastes in Guba Andreeva -on the radioecological state of its ambient environment is analyzed. Data on the concentration of 137 Cs and 90 Sr in the components of the land and marine ecosystems of the region are presented. It is shown that the radiation background and concentration of the technogenic radionuclides in the components of the environment are low and correspond to the background values characteristic for the Kola Peninsula and the coastal sea area. The effect of the waste storage site on the state of the ambient environment is very small and localized on sections adjoining the perimeter of the sanitary-protection zone.The radioecological state of Guba Andreeva, Guba Malaya Andreeva, and Guba Zapadnaya Litsa as well as the surrounding coastal territory is of interest for studying ecosystems with a prolonged source of contamination by technogenic radionuclides. The territory of the temporary storage site for radwastes in Guba Andreeva, which is now in the reconstruction stage, was contaminated as a result of the leakage of liquid radwastes and spills of solid radwastes as a result of impairment of the seal tightness of the packaging [1][2][3]. In this connection, the surrounding space and sea area were contaminated as a result of the transport of dust and fresh-water runoff.The aim of the investigation, performed in May 2012 jointly with the Federal Center of Nuclear and Radiation Safety and the SevRAO enterprise, was to analyze the effect of a radiation hazardous object on the radioecological state of the surrounding territory, water area, and terrestrial and marine biota.Natural Conditions of the Territory and Water Area of the Region of the Investigations. The temporary waste storage site occupies the territory of the cape, protruding into the water area of Giba Zapadnaya Lisitsa and forming a bukhta -Guba Andreeva -that is convenient for navigation. It lies on a coastal slope with a hilly relief and separate rocky elevations. The slopes of the cape have a steep slant toward the sea with steep sections. The rock base is comprised of ancient igneous rocks of the Precambrian shield and is covered by a moraine consisting of gravelly sandy loam and pebbly soils with sandy-loam and sandy fill. The thickness of moraines is 3.8-6.5 m. Marine sedimentary rocks, represented by sands, sandy loams, loams and clays, lying on deposits of the moraine, are observed in the coastal area. Marine deposits are developed in the northern part of the cape, forming Guba Andreeva and the territory of the temporary waste storage site. In other parts of the territory, they are encountered in fragments in the coastal zone and depressions in the relief between the water divides. The deluvial deposits are represented by large fragmentary hard-rock material and are developed on slopes [4].The surrounding landscape is subarctic tundra with fragments of forest tundra. The soil l...
