Advanced Surveillance,Diagnostics,and Prognostics Techniques Used for Health Monitoring of Systems,Structures,and Components in Nuclear Power Plants
(0) The International Atomic Energy Agency (IAEA)has initiated a new Coordinated Research Programme (CRP)on Surveillance, Diagnostics, and Prognostics (SDP)techniques and systems applicable to both existing and future nuclear power plants (NPPs). Twenty-five organizations from thirteen IAEA Member States take part in the research program. The project identifies, and plans to complete, research required in the fields of on-line monitoring, diagnostics, and performance prediction including data acquisition, processing and analysis techniques, integration, overall system operation and maintenance. Emphasis is given to (1)increased SDP needs in existing NPPs arising from power uprates and license renewals and (2)built-in SDP capabilities in new NPP designs. The research activities under this CRP are grouped into the following four separate areas: (1)Reactor signal noise analysis used for parameter estimation and dynamic testing, (2)Acoustic noise monitoring methods and systems used for loose parts monitoring and leakage detection, (3) Prognostics for structural integrity using on-line non-destructive techniques, and (4) Instrument and equipment condition monitoring and predictive diagnostics. This paper discusses the first two areas in detail. The technical subject of the CRP was identified by the IAEA Technical Working Group on Nuclear Power Plant Control and Instrumentation (TWG-NPPCI)as an area of high importance.
