Validation of lifetime extension of power-generating units with RBMK reactors

A list of measures for extending the lifetime of power-generating units with RBMK reactors is presented. The normative approaches and criteria are indicated, an assessment of the technical possibility of lifetime extension, primarily for the critical components, of at least 15 years is examined. The technical measures for safe operation after the lifetime has been exhausted are examined for the No. 1 unit of the Leningrad nuclear power plant. Finally, validation is given for the possibility of subsequent safe operation of the critical components, equipment, and pipelines of the multiple forced circulation loop up to 2018.[PUBLICATION ABSTRACT]
