On-power Detection of Pipe Wall-thinned Defects Using Ir Thermography in Npps

The number of aging nuclear power plants (NPPs) has increased recently. Accordingly, the number of operational interruptions has increased due to malfunctions of the NPPs secondary systems. These cases occur in the secondary systems of NPPs with a range of structures due to fatigue, wall-thinned defects, corrosion, etc. Of these problems, wall thinned defects occur in the pipes by the diffusion...

Risk-Informed Incident Management for Nuclear Power Plants

Decision making as a part of nuclear power plant operations is a critical, but common, task. Plant management is forced to make decisions that may have safety and economic consequences. Formal decision theory offers the potential for a structured approach capable of taking into account risk-related aspects (plant and worker safety, for instance) and, at the same time, important factors like eco...

New Generation Nuclear Power Plants

− The radioactivity measurement techniques being developed within the EMRP “MetroFission” Joint Research Project (JRP) [1], are aimed at performing on-site activity measurements, by the development of a portable Triple to Double Coincidence Ratio (TDCR) system along with associated digital electronics. The TDCR standardisation method for beta-emitting radionuclides (e.g. H and Pu) produces an e...

Seismic Isolation of Nuclear Power Plants

The paper presents the world state-of-the-art of the Nuclear Power Plants (NPPs) provided with seismic isolation and focuses on the main problems related to the application of this technology to so peculiar structures, characterized by high masses, large sizes and severe safety requirements due to the possibility of relevant accidents with release of radioactivity and other extremely dangerous ...
