KONKOLY THEGE MIKLÓS ÚT 1121 BUDAPEST, HUNGARY PROGRESS REPORT ON RESEARCH ACTIVITIES IN 2012 1 CENTRE FOR ENERGY RESEARCH PROGRESS REPORT 2012 Dear Reader, Welcome to the first Progress Report of the Centre for Energy Research, Hungarian Academy of Sciences. From January 1, 2012, the Institute of Isotopes joined the KFKI Atomic Energy Research Institute in the framework of a major reorganisation of the institute network of the Hungarian Academy of Sciences. The merging of the two institutes was carried out without substantial difficulties, however, it was a good argument to reconsider their strategies. As far as nuclear energy R&D&I is concerned, the strategy has remained unchanged. It consists of three basic elements, namely to provide the scientific background for the extended safe operation of the Paks NPP units, to participate in the preparation of constructing new nuclear units in Hungary, and to contribute to the international efforts related to the closure of the fuel cycle and the development of the new generation of power reactors. Concentrating human resources and infrastructures to these challenges is the most important duty of the management. Hopefully, the proposed Hungarian national nuclear R&D program will start rather soon and it will decisively influence the activities of the research centre. The establishing of a strong nuclear cooperation among the nuclear research centres of the Visegrád 4 countries aiming at the construction of a Generation 4 reactor also requires a strong governmental support. Additionally one can mention that the merging of institutes led to a situation when a great part of the national knowledge base on nuclear safety and security is concentrated in the same institution and the synergies can be utilized. As far as the Institute of Isotopes is concerned, a new strategy was elaborated in 2012. The objective was to establish an R&D&I institute for national energy strategy, comparative analysis of using various energy resources, R&D concerning selected versions of environmental friendly energies, energy storage, etc. The elaboration of the strategy required a lot of internal discussions and finally the strategy was accepted by the Hungarian Academy of Sciences. As a consequence, the name of Institute of Isotopes was changed to Institute for Energy Security and Environmental Safety (valid from January 1, 2013). The R&D&I projects of the research centre have been continued in 2013, basically in the same way as it was common in the former KFKI Atomic Energy Research Institute. The Progress Report presents the results of various projects in a uniform manner. I hope you will find interesting to get acquainted with the results presented in the Progress Report.
