Rosatom Central Institute for Continuing THE TRAINING COURSE VENUE ROSATOM CENTRAL INSTITUTE FOR CONTINUING Education and Training (ROSATOM-CICE&T) Obninsk the cradle of Russian nuclear technology for peaceful use is the homeland o f the First-in-the-World nuclear power plant. EDUCATION AND TRAINING From education to competence building The city was founded in 1956. The famous Obninsk NPP was started up The Rosatom-CICE&T the only corporate education and training we pave the way to career success two years earlier, on June 26, 1954. institution of Rosatom in the eld of technical competence building I am happy that I had the opportunity to get acquainted with was established in 1967 for accumulation and transfer of best for nuclear professionals Your plant. I dipped into the future... practices in USSR nuclear sector. Jawaharlal Nehru, 1955 Obninsk is one of the major Russian science cities. In 2000, it was awarded the status of the First Science City of Russia. ROSATOM The First-in-the-World International Nuclear Power Plant, Obninsk Connected to the power grid on Training Course: June 26, 1954 Since 2010 Rosatom-CICE&T has been providing training for specialists of national nuclear infrastructure for the countries embarking on nuclear power Specics of State Scientic Centre of the Russian Federation Institute for Physics programmes. and Power Engineering named after A.I.Leypunsky (SSC RF-IPPE) At the 55-th Session of the IAEA General Conference Rosatom- founded in 1946 is the heart of fast reactor technology.
