The conference "Nuclear Energy for New Europe" is a traditional annual meeting of professionals from nuclear research and educational institutions, nuclear utilities and regulatory bodies from Europe and abroad. In the past two decades the conference was organized in various places in Slovenia, and this year, the jubilee 20th conference paid tribute to its roots: Bovec was the venue also of the first conference in June 1992.

The editorial activities of these Proceedings started in December 2010 with Call for papers and 159 abstracts were submitted by May. A Program Committee meeting was held in June in Ljubljana where the program of the conference was outlined. Contributed papers presented a variety of new scientific, technical and operational results. Around one third of contributions were presented orally and others as posters. Each paper was reviewed by two referees before being included in the Proceedings.

Following the tradition of previous meetings, award was given for the best paper prepared by first author aged no more than 32 years. Fourteen young authors participated in the contest and two Awards for Young Authors were presented to:
Davide Rozzia, Italy, for the paper
