... more and more close to people’s life, and nuclear and radiation safety has also attracted more and more attention from all walks of life. Therefore, while making effective use of nuclear technology, it is very necessary to do a good job of risk identification and safety management and control. Doing...

... Abstract Risk informed safety margin characteristics (RISMC) analysis Method, is a safety analysis method which combines probability safety analysis and determinism safety analysis of nuclear power plant. General RISMC analysis platform “CARS” (Coupling Platform for Advanced Risk Simulation...

... because it could assess overall impacts of risks and help to identify vulnerabilities to determine next steps to address security risks. With the integration of information system and physical system, cyber security of information system and functional safety of physical system interact with each other...

... Abstract Radiation exposure is an essential measure of social welfare. Every day the public was exposed to radiation, whether they were aware of it or not. Public people can only receive no more than 1mSv of radiation in a year based on Basic Safety Radiation Protection Regulations 2010 under...

... Abstract The Generation IV (GEN-IV) international forum is a framework for international co-operation in research and development for the next generation of nuclear energy systems. Within the GEN-IV sodium-cooled fast reactor (SFR) system arrangement, the SFR Safety and Operation (SO) project...

... Abstract In high-level waste treatment plants, rooms where the highly radioactive sources (such as the vitrification containers) are operated have high radiation protection risk. On the purpose of ensuring the safety of operators, it is necessary to design corresponding shielding walls, windows...

..., European safety authorities released new reference levels in the framework of WENRA 2013 (Western European Nuclear Regulators Association) standards for new reactors [1] to address external hazards more severe than the design basis hazards. Considering this input, the French and UK nuclear regulators have...

... Abstract According to the Periodic Safety Review Process, the safety level is re-assessed every ten years, considering national and international operational feedback, evolution of knowledge and best available practices. Protection against natural hazards is part of this safety level re...

... Abstract Over the years, power plants have been hit by numerous severe weather events (storm, flood, heat wave...). EDF (Electricity of France) and ASN (Nuclear Safety Authority) want to assess the future impact of severe weather events on the power plants. Furthermore, recent research...

... Abstract Following the Fukushima Daiichi accident, the Western European Nuclear Regulators Association (WENRA) updated in 2014 the safety reference levels (SRL) for existing reactors, introducing a new chapter specific to natural hazards. In 2015, in preparation for the 4th periodic safety...

... fraction (ARF) of a 7A drum’s contents when exposed to a pool fire than what is assumed in current safety basis documents. This potentially different ARF is currently unknown because, while studies have been performed in the past to quantify ARF for 7A drums in a fire, no comprehensive measurements have...
