Activation analysis for materials of RF DEMO-S reactor was performed in order to choose appropriate waste management procedure. Helium cooled ceramics Li_4SiO_4 breeding blanket option was considered. The consideration is based on European waste forth-levels (NAW, LLW, MLW, and HLW) classification, which is adopted by IAEA. Ultimate aim of waste management is hands-on recycling for major part of reactor materials. For this goal low Activation materials is proposed with limiting contents of long-term impurities. RF Sanitary Rules of Radioactive Waste Management (SRRWM-85) and US NRC rules 10CFR61 were considered. Radiological safety is estimated Waste Management (SRRWM-85) and US NRC rules 10CFR61 were considered. Radiological safety is estimated According to RF Radiogical Safety Norm (RSN-96) guideling, which is based on International Commission on Radiological protection (ICRP) recommendation.
