Nuclear Power Production

<p><span>By analysing the two long-lived anthropogenic Uranium (U) isotopes U-233 and U-236 in different compartments </span><span>of the environment affected by releases of nuclear power production or by global fallout from nuclear weapons tests</span><span>, we showed that the corresponding isotopic ratios U-233/U-236</span><span> differ by one order of magnitude. Based on these experimental results which were obtained with the ultra-sensitive detection method Accelerator Mass Spectrometry, we suggested a representative ratio for nuclear weapons fallout of </span><span>U-233/U-236</span><span> =</span><span> (1.40 ± 0.15) ·10</span><sup><span>-2</span></sup><span> and (0.12 ± 0.01) ·10</span><sup><span>-2</span></sup><span> for releases from nuclear power production. Consequently, the </span><span>U-233/U-236</span><span> ratio not only </span><span>has the potential to become a novel sensitive fingerprint for releases from nuclear industry, but could also serve as a powerful oceanographic tracer due to the conservative behaviour of U in ocean water which does not suffer from chemical fractionation. </span></p><p><span>As a first application of this paired tracer, we studied the distribution of U-233 and U-236 concentrations in addition to I-129 in the Baltic Sea which is known to have received inputs of radionuclides from various contamination sources including the two European reprocessing plants, global fallout from weapons testings and fallout from the Chernobyl accident. Our data indicate an additional unidentified source of reactor U-236 in the Baltic Sea demonstrating the high sensitivity of the U-233/U-236 ratio to distinguish different emission sources in water mixing processes.</span></p>

The Impact

Abstract. The results of the study aimed to assess the influence of future nuclear power plant Hanhikivi-1 upon the local thermal conditions in the Bothnian Bay in the Baltic Sea are presented. A number of experiments with different numerical models were also carried out in order to estimate the extreme hydro-meteorological conditions in the area of the construction. The numerical experiments were fulfilled both with analytically specified external forcing and with real external forcing for 2 years: a cold year (2010) and a warm year (2014). The study has shown that the extreme values of sea level and water temperature and the characteristics of wind waves and sea ice in the vicinity of the future nuclear power plant can be significant and sometimes catastrophic. Permanent release of heat into the marine environment from an operating nuclear power plant will lead to a strong increase in temperature and the disappearance of ice cover within a 2 km vicinity of the station. These effects should be taken into account when assessing local climate changes in the future.

The article discusses the outcomes of the researches of zoo/plankton of various type nuclear power plants cooling pools located in different in terms of hyd ro g r aph ic c h a r ac t e r i s t ic s a nd z o opl a n k t on s t r uc t u re c at c h ment b a s i n s . I n Kop or ye B ay, a part of the Bay of Finland water area, discharge of warmed waters of Leningrad Nuclear Power Plant caused the decrease of plankton invertebrates’ quantitative indicators. In the Beloyarsk Nuclear Power Plant cooling pool warming in the most cases was favorable for the zooplankton abundance and biomass increase. In both researched reser voirs the warm water discharge resulted in the decrease of the total species number in the communities. The Neman River (the Baltic Nuclear Power Plant designed receiver for waste waters) in the period of the research was not affected by the nuclear plant impact. As a whole, for this water course water area ma ximal values of zooplankton abundance and biomass have been registered during spring periods while their decrease has been observed in summer and autumn. The most degree of trophity was noted near towns of Grodno, Kaunas, Yurbarkas and Neman.
