Title: Safety Assessment Method and System for Radioactive Waste Complex Disposal Facility
Inventor: KIM HYE JIN
IPC: G06Q50/26
Filed: 2021-02-18
Granted: 2021-08-23
Abstract: Disclosed is a data processing technology for evaluating safety of a radioactive waste disposal facility. Nodes included in a radiation exposure scenario are divided into a transport medium node and a radiation exposure medium node and a radiation exposure dose for each radiation exposure scenario is calculated based on unified modeling of these. A radioactive waste transport process of the transport medium is modeled as a transport mechanism and a radiation exposure process of a radiation exposure medium is modeled as a Shine mechanism. The radiation exposure dose for each radiation exposure scenario can be calculated by sequentially calculating transport and exposure amounts between individual nodes along the nodes of the radiation exposure scenario. A complex disposal facility radiation exposure can be evaluated from a radiation exposure dose for each disposal facility by reflecting a groundwater flow model.
