In this regard, it is expected that in the coming decades (possibly centuries), in the industrial application of CTS in powerful TNR of a particular design, only a mixture of heavy (deuterium [sub.1.sup.2]H) and superheavy (tritium [sub.1.sup.3]H) hydrogen isotope [sub.1.sup.1]H (protium) will be used as thermonuclear fuel [5, 14, 19].
The data on the ADSCs viability at 24 h and 72 h indicate that cell cultures are able to adapt to the replacement of protium by deuterium (at 24 h the acute toxicity in group No.1 is observed (Table 3), although the level of chronic toxicity remains high at 72 h).
