Message from the President

Toru Yamaji, President

The nuclear power covers 30% of Japan's power generation, and it is considered as an environment friendly energy source because of its effective reduction of CO2 emission, which is one of the factors of global warming. According to Japan's national energy policy, nuclear power generation is promoted in our country, besides recycling uranium resource used for the power generation due to limited availability of the energy resources.

Nuclear Waste Management Organization of Japan (NUMO) was established in line with Japan's Specified Radioactive Waste Final Disposal Act. Our mission is to implement safe and secure geological disposal of vitrified high-level radioactive waste (HLW) and low-level radioactive waste with low heat production and long half-lives (TRU waste), which are by-products from the uranium recycling process.

Like other overseas countries, the research and development on geological disposal have been driven forward over 3 decades in Japan and the technical basis has been established robustly.

Based on this technical basis, NUMO will promote the disposal project that includes investigations, selection of repository site(s), construction, operation and closure of the repository, prioritizing on securing safety in accordance with basic principles: stepwise project development, respecting initiatives by local communities and transparency in the project.

Because of highly public and long-term nature of the geological disposal project, which extends to about 100 years, the voluntary decision by the local communities is considered the top priority. Hence, NUMO adopted an open solicitation approach to find candidate areas for the feasibility study of final repository from countrywide municipalities.

Our stepwise siting process consists of three stages: literature survey, preliminary investigation and detailed investigation. Areas to be surveyed or investigated at each stage will be selected carefully in respect of opinions of the concerned local communities.

While enthusiastically committing to communication activities to achieve mutual understanding on necessity and safety of geological disposal and focusing on further technical development, NUMO will proceed the project to launch repository operation around late Heisei 40 (late 2030), working closely with the government and power suppliers who are also waste generators.
