“…To ensure safe operation, constant monitoring and evaluation of the technical condition of the containment at all operation stages are carried out. For containment constructed in recent times in accordance with NP-010-16 " Rules for the Design and Operation of Localizing Safety Systems for Nuclear Power Plants" methods for monitoring its technical state have been developed and implemented [1][2][3][4][5][6]. For containments erected in 1980-2010, the task of assessing the technical state remains relevant, and in some cases this task becomes critical.…”

The theory of the containment technical condition estimation of NPP units is considered in the paper. The theory is that the results of a regular built-in system intended for determining and evaluation of the containment stress-strain state during the acceptance and operation period must be duplicated by the mobile geodetic system results, obtained at the same stages of the containment existence. At the same time, the proposal for applying this theory to the containments constructed in 1980-2010 has been developed. The possible initial working environment is considered and the proposals for this technique implementation are introduced in the conditions under consideration. The proposals presented provide an objective control of the containment for an unlimited period of their operation.
