“…The applications of TOUGH-FLAC cover geothermal (e.g., Jeanne et al, 2015;Rinaldi et al, 2015a), nuclear waste disposal (e.g., , compressed air storage systems , shale gas 2015), as well as geologic carbon sequestration (Rutqvist et al, 2008; and related induced seismicity (Cappa and Rutqvist, 2011;Rinaldi et al, 2014aRinaldi et al, , 2014bRinaldi et al, , 2015bRutqvist et al, , 2016Urpi et al, 2016). On the other hand, iTOUGH2 (Finsterle, 2004;2007;Finsterle et al, 2014) has been largely used for sensitivity analysis and parameter estimation for several hydrogeological application (e.g., Doetsch et al, 2013;Finsterle et al, 2013;Poskas et al, 2014;Wainwright et al, 2013;Yuan et al, 2015). Thanks to the PEST protocol (Doherty, 1994), the use of the inverse capabilities of iTOUGH2 can be extended to any numerical forward model; here, we apply for the first time the code iTOUGH2-PEST (Finsterle and Zhang, 2011) to a coupled fluid flow and geomechanics application.…”

“…Considering the mass flux and radionuclide radiotoxicity, it was observed that radionuclides 129 I and 226 Ra (in the long-term) are the dominant radionuclides in the release from the engineered barriers. In the study [12] the comparison of peak fluxes from the near field for Lithuanian RBMK-1500 and Swedish BWR SNF revealed differences that are not directly proportional to the differences in SNF inventory. This paper focuses on probabilistic uncertainty and sensitivity analysis of 129 I and 226 Ra release through the engineered barriers of the repository with RBMK-1500 SNF.…”

“…Preliminary studies on the radionuclide transport through the engineered and natural barriers of the conceptual repository for RBMK-1500 SNF were performed and presented in [10], [11], [12]. Considering the mass flux and radionuclide radiotoxicity, it was observed that radionuclides 129 I and 226 Ra (in the long-term) are the dominant radionuclides in the release from the engineered barriers.…”

“…Analizuojant PBK šalinimo Lietuvoje galimybes, atliktas giluminio atliekyno įrengimo kristalinėse uolienose išlaidų įvertinimas bei pradėtas bendrasis atliekyno saugos vertinimas [30]. Tęsdami saugos vertinimus, LEI Branduolinės inžinerijos problemų laboratorijos mokslininkai analizavo atliekyno evoliucijos scenarijus, atliekyno aplinkoje išliekant dabartinėms sąly-goms, joms keičiantis, esant nesandariam vienam iš šalinimo konteinerių, įvertinta įvairių veiksnių įtaka radionuklidų [31][32][33][34][35][36][37] ir dujų [38][39][40] sklaidai bei tarpusavyje susijusių šilumos mainų (T), fluidų (dujų ir vandens) pernašos (H) ir mechaninių procesų (M) įtaka atliekyno saugai [41][42][43][44]. Geologijos ir geografijos instituto tyrėjai vykdė požeminio vandens tekėjimo ir radionuklidų sklaidos iš PBK atliekyno kristalinėse uolienose pietrytinėje Lietuvos dalyje skaitinius vertinimus [45][46][47].…”

“…Tęsiant tyrimus buvo išnagrinėti radionuklidų sklaidos iš skirtingų reaktorių PBK ypatumai bendrinėmis sąlygomis [36]. Tyrimo metu buvo analizuojama radionuklidų, susidariusių Šve-dijos PBK ir Lietuvos RBMK-1500 kuro rinklės konstrukcijose bei pačiame branduoliniame kure, sklaida.…”
