Modern nuclear physics is impossible without the implementation of projects of the megascience class, for the creation of which the efforts of many organizations and countries are consolidated. The level and complexity of experiments carried out with the use of such facilities is provided by scientific researchers with a wide range of competencies. The education of such researchers is an important task for scientific and educational organizations. These issues were discussed at the 2nd conference "Personnel training and legal support for the implementation of scientific projects of the Mega-science class" organized by National Research Nuclear University MEPhI and Kutafin Moscow State Law University on June 25, 2020. The aim of the Conference was to discuss the policy management issues of implementation of the Mega-science class research projects.
