| Abstract | The Government of the Russian Federation has intention to develop nuclear energy and involve in the fuel cycle additional amount of fissile materials. In theory it could lead to increasing activities of terrorist's groups by using nuclear materials as an object for blackmailing. The governmental system of nuclear material control and accounting was dedicated to prevent alike scenarios. Unfortunately, this continuously improving system still has some dark spots. One of those is possibility of unique seals faking. According to official ROSATOM guidelines for applying sealing technologies: “…there is no official data concerning sealing systems that could not be faked…”. At the same time, G8 states propose “3S (safety, security, safeguards)” initiative during 34th G8 summit, the main idea is to unite methods by using different “S” areas. Within this initiative TOLMI has launched the project on NDT methods application for fingerprinting by structural features of containers with nuclear materials. Nowadays, NDT is mainly focused on safety purposes, but it seems possible to apply these methods for providing national and IAEA safeguards. The microstructure of the containers material as well as of the dedicated weld seam applied to the lid and the container body provides a unique fingerprint of the full container, which can be reproducibly scanned using an appropriate technique. Weld seams investigation performed by ultrasonic backscattering technique for providing those fingerprints is described in the paper. |

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.
