Particulate organic carbon (POC) concentrations were 0.44–5.01 mg L -1 , and δ 13 C and ∆ 14 C values were, respectively, –30.3 to –22.8 ‰ and –156 to –33 ‰. The organic matter in suspended solid samples consistently showed depleted 14 C, with an average ∆ 14 C value of –81 ± 37‰. The carbon isotopes showed seasonal variation, being higher in summer, and with a positive correlation to POC contents. These results suggest that the POC characteristics are controlled by a mixture of two endmembers, organic matter produced by phytoplankton activity within the lake and the watershed organic matter, under a shallow and semi-closed environment.","PeriodicalId":16569,"journal":{"name":"Journal of nuclear and radiochemical sciences","volume":"24 1","pages":"17-22"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75942967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The public’s concern stems not only from the worry over the safety of nuclear power plants (NPPs) but also from that over the management of high level radioactive waste (HLW). In order to alleviate the public’s concern over the management of HLW, transmutation of long-lived radioactive nuclides can be an effective measure from the viewpoint of reducing the life, heat and toxicity of HLW. The three systems of fast reactor (FR), accelerator-driven system (ADS) and molten salt reactor (MSR) are compared in terms of the efficiency of transmutation of HLW or minor actinide (MA) waste, the main component of HLW.","PeriodicalId":16569,"journal":{"name":"Journal of nuclear and radiochemical sciences","volume":"5 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83754316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
