The Introduction of the Safety Assessment of HLW Disposal in 2014–2017 in China

Conference paper


In China, “The Law on Prevention and Control for Radioactive Pollution” issued in 2003 determined that the high-level waste will be disposed in a deep central geological repository. The main work of China Institute for Radiation Protection (CNNC-mandated comprehensive research) about HLW disposal is safety assessment. In 2006–2010, the CIRP have done some of the works about safety criteria and safety requirements: public radiation protection for post-closure of repository: 0.3 mSv/a; timescale: 10,000a. The CIRP also have established SA methodology and routine. Some software about safety assessment such as AMBER, Ecolegy, GoldSim, ProFlow can be familiarly used. The main works in 2014–2017 about the safety assessment that will be done are the research of safety requirements of the EBS and host rock, the research of safety function of the EBS and host rock, establishing the safety indicators’ system of the EBS and host rock, establishing the FEPs list and the scenario analysis in the conceptual and planning stage, the near-field temperature simulation based on the conceptual design of the repository, and the safety assessment of Beishan Preliminary Repository. Some of the above-mentioned work details will be introduced in this paper. The scenario development is the key step in HLW geological disposal. The features, events, and processes (FEPs) should be first considered. The FEPs can be sorted and grouped to form the scenario. It is very useful and has reference valve for developing the FEPs of HLW geological disposal in a conceptual and planning stage in China by introducing the FEPs’ established and sorted methods. The FEPs list will be built in 2014–2017. Some of the works will be researched in 2014–2017. The details of these works will be introduced in this paper.
