Integrity assessment of spent fuel assembly in vertically and obliquely dropping cask
Journal of Mechanical Science and Technology, 2021It becomes important to manage adequately spent nuclear fuels (SNFs) for storage away from reactor and/or final disposal as the plant onsite capacity nearly reaches to saturation state. Although the Korean government has enacted relevant regulations and safety measures including several kinds of test for transport cask, a matter of interest should be ...

A spray cooling technique for spent fuel assembly stored in pool
Kerntechnik, 2016Abstract For the safety of spent nuclear fuel assemblies stored in storage pool in the extreme condition where the water is lost completely, a passive spray cooling technique was designed, and its effectiveness has been validated by a functional experiment.

CFD simulation of air ventilated spent fuel cask design for PWR fuel assemblies
2016 International Conference on Emerging Technologies (ICET), 2016Dry storage casks are standalone containers that can be used to store spent nuclear fuel for an extended period of time. This paper is about the modeling and simulation of air ventilated dry storage cask used for long term storage of spent fuel assemblies from pressurized water reactors.

Investigation of the spent RBMK fuel assembly encapsulation by hot isostatic pressing
Atomic Energy, 2007A block diagram of spent fuel assembly encapsulation, a scheme for outfitting a gasostatic facility, a brief description of the construction of the gasostat, and a proposed design of a protective capsule containing one spent RBMK fuel assembly are presented. An isostatic processing scheme, which makes it possible to obtain long, defect-free, protective

Neutron Resonance Transmission Analysis of Reactor Spent Fuel Assemblies
1983A method called Neutron Resonance Transmission Analysis (NRTA) is under study which would use a pulsed neutron beam for nondestructive isotopic assay of a complete spent fuel assembly. Neutrons removed from the collimated beam by absorption or scattering in the resonances of the various isotopes in the spent fuel appear as dips in the neutron ...

Integrated Nondestructive Assay Systems to Estimate Plutonium in Spent Fuel Assemblies
Nuclear Science and Engineering, 2015AbstractAn integrated nondestructive assay (NDA) system combining active (neutron generator) and passive neutron detection and passive gamma (PG) detection is being analyzed in order to estimate the amount of plutonium, verify initial enrichment, burnup, and cooling time, and detect partial defects in a spent fuel assembly (SFA).

Nuclear Analysis for the Boraflex Used in a Typical Spent-Fuel Storage Assembly
Nuclear Technology, 1995The safety and credibility of boraflex, a neutron absorbing material widely used in the spent-fuel storage assembly, has been analyzed from a nuclear point of view. The nuclear heating (absorbed dose) rate and the neutron-induced radioactivity for the boraflex under a typical nuclear environment were calculated.

Effective Thermal Conductivity and Edge Conductance Model for a Spent-Fuel Assembly
Nuclear Technology, 1994In a typical transportation or storage cask, each spent-fuel assembly resides in a square enclosure that is backfilled with a nonoxidizing gas. For design purposes, it is desirable to have a simple yet accurate method to predict the maximum fuel rod temperature in a spent-fuel assembly in these casks.
