Quality control of in-service inspection in nuclear island
During the refueling outages of PWRs, ISI in nuclear island will contribute to find the equipment degradation generated during its normal operation, which can lay a foundation for the safe operation of nuclear power plant. ISI of nuclear island equipment was carried out from two sides: implementation and management. A detailed process of nondestructive testing and quality control during the preparation stage, project implementation stage and postsession integration stage was presented in accordance with the project procedures. Main responsibilities of quality control personnel stand out in the whole process.
Management Process and Human reliability Analysis of In-service Inspection for the Mechanical Components in PWRs
Based on the management strategy of in-service inspection, emphatically analysing the human reliability of in-service inspection persons, aimed at improving the management system and raising the management level for in-service inspection for the Mechanical components in PWRs.
Correlations for mass transfer between fluidized spheres and a liquid
Abstract Data on mass transfer between the solid particles and the liquid in a fluidized bed have been analyzed. After a convenient selection, various correlations have been derived. They show that for a given fluidized system, the Sherwood number is independent on the Reynolds number.
