Popis: Monitoring and assessment of the technical condition of underground pipelines of process systems important to safety is a relevant task of the ageing management process for existing NPPs. Methods applied in other industries having underground pipelines (oil/gas/public utilities) could be considered. The paper is devoted to theoretical issues of overcoming the interfering redundancy contained in the mutually correlated functions of the acoustic method for inspection of underground pipelines. The method has been tested in intensive leak inspection of urban heating pipelines and potentially could be beneficial for detecting leaks in the early stages of their occurrence in underground pipelines of the essential service water system at NPPs.
