研究期間：10203~10212;The success of low-level radioactive waste disposal facility requires comprehensive safety assessment and establishment of solid review techniques. Accomplishment of safety assessment should be provided for communication with the general public to reduce uncertainties on the safety concern of repository. Recent developments of the review techniques on radioactive waste disposal facilities were to meet the requirement of safety regulation to secure each step of facility design, safety assessment, construction, and operation. The Review Guidelines on Safety Assessment of Low-Level Waste Disposal Repository (0 version) was completed by the Fuel Cycle and Materials Administration in 2012. In order to improve the review guidelines and review techniques, the purpose of this study focuses on broad issues related to safety assessment reviews in low-level radioactive water disposal facilities. We will first review and analyze recent developments of safety models and verification techniques suggested by the International Atomic Energy Agency. The approved safety assessment conducted at the Texas Andrews site will be intensively evaluated as our major references. Other nations having similar site characterizations to Taiwan will be selected for further references focusing on what models, procedures, and results they employed for fulfilling the regulation requirements. With these intensive literature reviews, we will build the clear linkage between what data and results the applicant should prepare for safety assessment with respect to what key issues should be concerned in safety assessment on the regulation side. The purpose is to improve the review techniques and enhance the review guidelines on all aspects related to safety assessment. Suggestions on revision of broad issues related to safety assessment in the Review Guidelines on Safety Assessment of Low-Level Waste Disposal Repository will be provided to improve review capabilities of regulators and to enhance safety assessment techniques of applicants.
