| Abstract | The pending upgrade of the Tokamak Fusion Test Reactor (TFTR) for D-T operation will require extensive changes to the supporting hardware around its perimeter. The entire machine will be surrounded by 30 in of reinforced concrete, making access to the subsystems on the TFTR nearly impossible. A review and modification of each subsystem will be required to ensure compatibility with the concrete igloo. One of the major changes included a complete redesign of the vacuum vessel heating/cooling system. Relocating the main cable tray system which is presently located around the upper perimeter of the machine was another major task. These trays carry the cables for the bakeout heating system and for numerous diagnostic systems. A system to control the routing of existing and new systems that require a penetration through the new igloo or enclosure walls was set up. These penetration documents will control all items passing through the igloo shield. The process by which TFTR will be prepared and modified so that the new igloo walls can be installed is described. Several of the major subsystems being modified are discussed.< |

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.
