Used nuclear fuel storage options including implications of small modular reactors
This work addresses two aspects of the nuclear fuel cycle system with significant policy implications. The first is the preferred option for used fuel storage based on economics: local, regional or national storage. The second is the implications of small modular reactor (SMR) introduction for the …

COMSOL finite-element analysis : residual stress measurement of representative 304L/308L weld in spent fuel storage containers
The ultimate storage destination for spent nuclear fuel in the United States is currently undecided. Spent fuel will be stored indefinitely in dry cask storage systems typically located on-site at the reactor or at a dedicated independent spent fuel storage installation (ISFSI). Since these …

On selection and operation of an international interim storage facility for spent nuclear fuel
Disposal of post-irradiation fuel from nuclear reactors has been an issue for the nuclear industry for many years. Most countries currently have no long-term disposal strategy in place. Therefore, the concept of an intermediate nuclear spent fuel storage facility has been introduced as a method of …
