Adequacy of normative documentation to actual operating conditions of the pressure seal cables VGKK for nuclear power station

The normative documentation regulating sealing materials quality which separate the NPP accident localization zone is reported. The inadmissibility of the additivity principle application which is laid the foundation of current normative documentation covering the NPP accident localization zone output is concluded. It is shown that the qualification testing of the primary coolant circuit calls for accounting all factors arising from the reactor accident. The latter is cited as an example by using the hermetic cable input of controlling circuits
