| Abstract | To enhance the containment integration for nuclear safety, sealing performance of those numerous penetrations has to be concerned. Surface roughness of the sealing pairs contact ends has great influence on the leakage characteristics. Following the essence of leakage phenomena, a theoretical mechanism model of leakage rate for rubber sealing structure was built based on percolation theory, where rough contact interface was treated as an aperture region. Deformation behavior of the roughness was solved by using Hertz contact theory. The mechanism model can realize the conversion of leakage rate between different operating conditions, which is important to leakage rate prediction. And the model can be easily combined with macro mechanical analysis of the sealing structure, which is helpful for their optimum design. Validation and convenience of this model is verified through two concrete examples. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
