The Waste Treatment Facility No. 1 is equipped with an incinerator for the treatment of radioactive combustible solid waste generated from facilities at the Nuclear Science Research Institute. To obtain conformity confirmation with the New Regulatory Requirements, seismic evaluations were conducted on the facility's building and its incineration equipment. As a result, neither the building nor the equipment satisfied the required seismic standards. Therefore, seismic reinforcement work for the building and equipment was carried out from April 2018 to March 2019. This report outlines the results of seismic evaluation and design, as well as the construction process and safety management during the seismic reinforcement work.
