“…Stable isotope ratio mass spectrometry and computer modelling can be very useful to restore the irradiation parameters of graphite or other carbonaceous materials by using experimental and modelling results of 13 C generation in the irradiated material [51]; consequently, by combining aerosol mass spectrometry, stable isotope mass spectrometry, chromatography, and computer modelling the solutions of environmental problems in the future can be found.…”

“…However, only part of nuclides in minor places of interest could be measured in the graphite stack directly. Because of that, modelling of build up of activation products in the reactor and validation of calculated results with ones determined experimentally in a limited amount of accessible points is the only affordable way to evaluate the activity of short-and long-lived radioactive waste [3][4][5][6].…”

In this work concentrations of minor graphite impurities in virgin graphite of the Ignalina Nuclear Power Plant (Ignalina NPP) measured by high resolution inductively coupled plasma mass spectrometry (ICP-MS) are presented and applicability of the method for the evaluation of minor graphite impurities is discussed. It is shown that ICP-MS is a promising technique for determination of graphite impurities in 10 ppm -10 ppt concentration range as a rapid and relatively cheap method. The most important nuclides for evaluation of short-and long-lived activation products in the Ignalina NPP graphite were measured with the accuracy sufficient for the radioactive waste classification. These results could be used for planning of dismantling and disposal of the Ignalina NPP graphite.

“…There are several papers dealing with the problems of the irradiated Ignalina NPP graphite [Ancius et al, 2005, Mazeika et al, 2015, Narkunas et al, 2010, Plukiene et al, 2014, Remeikis et al, 2010, Smaizys et al, 2005 or the graphite of other NPPs with RBMK reactors [Bylkin et al, 2001, Bylkin et al, 2004. Some of them provide numerical estimations [e.g.…”
