| Abstract | In this paper, the effect is discussed of both pressure and temperature variations and their bearings on the SRA UHB safety factors. A variable peak distribution characterised by probabilities of distinct design and operating conditions is proposed and developed for performing OOS UHB. A routine has been developed recognizing that such a distribution is generally not available in the SRA software. Bearing in mind that friction is an important parameter in the UHB and OOS analysis but not duly considered in the literature to date, an integrated UHB model is introduced in the SRA to account for axial friction. The probabilistic methodology, its implementation and significance are shown through a series of SRA and parametric studies using Monte Carlo simulations. It is demonstrated that a more sensible UHB SRA can be achieved to minimise unnecessary margins, whereby the design parameters can be represented by appropriate probability density functions taking into consideration of maximum design, operating and surge excursion conditions, system availability and reliability levels. Some conclusions and recommendations are presented on the selection of SRA input parameters. |

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.
