Abstract
It’s suggested to develop the additional NPP measuring channels verification regulations in order to reduce verification labourintensiveness and increase economic NPP operation efficiency. This regulations should afford an opportunity for componentwise verification and for basic and alternative complete verification of the NPP measuring channels depending on the verification reliability requirements. The uniformly precise, cross and combined methods are identified as alternative methods of complete verification. This article proposes the main regulations development problems and presents requirements for the basic regulations provisions. It’s emphasized that the developed regulations of the provisions on the application complete verification of the NPP measuring channels should allow: to control the channel error as a single measuring device without demounting its components; to reduce the verification time allocated during power generating unit hold; to preserve the acceptable level of the measurement channel verification results reliability. An example of the complete verification reliability estimation procedure is given as one of the most important criteria for selecting the verification method.
