Chemical interaction layer between uranium oxide fuel pellet and zirconium alloy cladding in pressurized water reactor

open access: yesHe jishu, 2023
BackgroundDuring reactor operation, zirconium (Zr) alloy cladding is continuously oxidized as it gets in contact with fuel, and combines with the fuel to form a firm chemical interaction layer.

Chromium-Coated Zirconium Cladding Neutronics Impact for APR-1400 Reactor Core

open access: yesEnergies, 2022
The accident-tolerant fuel concept involves replacing the conventional cladding system (zirconium) with a new material or coating that has specific thermomechanical properties. The aim of this study is to evaluate the neutronics performance of a chromium

Development of fuel behavior analysis code for mechanical fuel cladding failure during reactivity insertion event in PWR

open access: yesMechanical Engineering Journal, 2021
Pellet-Cladding Mechanical Interaction (PCMI) failure is one of the failure mode which must be evaluated in nuclear fuel safety. PCMI is caused by mechanical load to the cladding due to fuel pellet expansion.

Numerical simulation of the effects of localized cladding oxidation on LWR fuel rod design limits using a SLICE-DO model of the FALCON code

open access: yesNuclear Engineering and Technology, 2020
A methodology for evaluation of mechanical and thermal effects of localized non-axisymmetric oxidation in zircaloy claddings on LWR fuel reliability is proposed. To this end, the basic capabilities of the FALCON fuel behaviour code are used.
