National Centre for Nuclear Research (NCBJ) has been created on September the 1st 2011 by the decree of the Polish Government with a clear goal to form Technical Support Organization for Polish regulator and public administration. It was done by merging two institutes, the former Institute of Atomic Energy POLATOM and the former Andrzej Soltan Institute for Nuclear Studies, which worldwide reputation and successful research in various fields of nuclear power-related studies are well known. The fields of activity are widely focused on the nuclear physics, cosmology, electronics as well as detectors, accelerators, material research and many more. The main factor of National Center for Nuclear Research development was the participation in the European Structural Founds program "Swierk Computing Centre" from the beginning. In the frame of this particular program, the collaboration with the IAEA, NEA OECD, Euratom and research and TSO organizations from different countries began. The international collaboration plays the key role in the development of the Technical Support Organization expertise, which aim is to become the institution able to provide experts' support for decision-makers in nuclear power industry in Poland. Expertise and knowledge is expanded by the engagement in the large scope of safety code users international trainings, by being involved in various projects and benchmarks. The National Centre for Nuclear Research participates in, among the others, EURATOM projects such as NURESAFE (creation of BE Codes platform). Moreover NCBJ is involved in EURATOM FP7 projects such as NC2I-R (Cogeneration Initiative), ASAMPSA_E (Advanced PSA), and ALLIANCE as part of the ALLEGRO project. In most of these groups our centre is taking active part in development as well as in management activities. Thanks to experiences gained and with work on research we are effectively expanding knowledge, experience and expertise to meet future's demands as a Technical Support Organization for first Nuclear Power Plant in Poland. The IT infrastructure of "Swierk Computing Centre" is located in newly adapted building in Swierk which is specially dedicated for the headquarters of the Centre. This Centre will prepare the competence base capable of providing advanced data processing services for domestic nuclear power engineering and conventional power industry, simulations of fuel processes, simulation and monitoring of radiological hazards as well as to conduct scientific and developmental research in related fields.
