METHOD OF ASSESSMENT OF RELIABILITY OF PROTECTIVE CONTAINMENT OF NUCLEAR REACTOR Russian patent published in 2016 - IPC G01M99/00 

FIELD: building.

SUBSTANCE: invention relates to the field of construction and operation of nuclear power stations and, in particular, to the period of the prestressing, testing and subsequent operation of the hermetically sealed reactor containments offices reactor. Method is specified on the labeling section of the protective containment controlled points and performing cycle-wise determine their position. In this study surveying created with reference to the axes forming the capital or building structures protective containment or structural elements of technological equipment installed in the containment. In monitoring the internal and (or) the external geometric parameters determine the protective containment phases after complete erection of the sealed containment after its complete program voltage. When tested at the stage of creating the maximum internal pressure and subsequently the operation during each scheduled preventive maintenance, according to the results obtained phased interstage determines the amount of displacement parameters of the test points. Specify interstage movements controlled points determine the safety factor of constructions protective containment and determine the condition of compliance with the operational reliability of the protective containment.

EFFECT: technical result is to increase the accuracy of the estimate of operational reliability sealed protective casings according to the results of the prestressing, the tests and the subsequent maintenance period.
