Now only one Dry Storage Facility of Spent Nuclear Fuel (DSFSNF) is operated in Ukraine – facility on Zaporizhska NPP. Many different thermal investigations were done for ventilated containers of DSFSNF. In this work the generalization of scientific approaches to the thermal safety assessment are carried out. The multi-stage approach to the definition of thermal state of containers' group,...
Bushehr Nuclear Power Plant, commercially operated in Sep 2013, is a Russian type VVER 1000/446; its reactor core consists of 163 fuel assemblies which have 3 up to 4 years’ fuel life time. In this pressurized water reactor, removed spent fuel assemblies are transferred into a pool near the core. This pool has been designed to store spent fuels for 9 years and after this period, this pool will...
The IRSN (Institut de radioprotection et de sûreté nucléaire), the French technical support organization, was asked by the parliamentary inquiry Committee on the safety and security of nuclear installations to provide a report on the concepts and safety issues regarding storage of spent fuel from nuclear power reactors.
Based on its expertise in France and on its knowledge acquired during...
Thermal analyses of dry storage systems use margins in their design basis input assumptions to ensure the peak cladding temperature does not exceed an established regulatory limit. Due to these margins, a best-estimate understanding of the thermal behavior of the dry storage system is generally not available from these design licensing basis models. The development of accurate best-estimate...
Spent nuclear fuel (SNF) possesses potential security risks; consequently, nuclear security issues have to be considered and addressed for effective management of SNF. The vulnerability of SNF to theft, for constructing a radiological dispersal device, and to the terrorist attack during storage or transport is a major concern for States having such type of nuclear materials. Hence, the...
On March 2019, the regulatory body of Japan, NRA, issued new regulations on dual purpose cask (DPC) for dry storage of spent fuel on the site, along with the licensing process of design certification on DPC. The requirements ensure consistency with those for the interim storage facility off the site and with transport regulations.
