The high-level underground research laboratory (URL) is not only a test facility used to understand the deep geological environment and crustal stress, obtain deep rock and water samples, and verify the long-term performance of engineering barriers in the real deep geological environment, but also an important means to develop and verify the construction, backfilling and sealing technologies of the repository. It is an essential platform for the research and development of high-level radioactive waste disposal technology. In order to reduce safety risks in the operation of URL, by analyzing factors such as the engineering characteristics, spatial structure, and personnel distribution of URL, and in response to potential safety risks in URL, a study was conducted on the design of emergency evacuation facilities for URL. Through research, rescue chambers were identified the location of the mobile rescue capsule and the disaster avoidance route of the URL have been developed, and emergency plans have been developed for the safe operation of the URL under disaster conditions.
