| Abstract | Upgraded Apsara reactor is a 2 MW pool type research reactor. The reactor core is surrounded by two layers of BeO reflector assemblies. Three dimensional conjugate heat transfer analysis is carried out for the BeO reflector assemblies to predict the temperatures of the BeO as well as the aluminium surface which is used for cladding the BeO reflector. These reflectors get heated up due to interactions with neutrons and gamma rays from the reactor core. Since no dedicated forced cooling is provided to cool these reflector assemblies, the heat transfer from them mainly takes place by natural convection. These reflector assemblies are immersed in a pool of water which acts as the heat sink. In order to estimate the temperatures of aluminum clad, coolant water and BeO, a detailed three dimensional heat transfer analysis is carried out using computational fluid dynamics software PHOENICS. The results indicate that the maximum air gap between aluminium side clad and BeO blocks should not be more than 0.3 mm to keep the temperatures well within limits. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
