Title: Young's modulus evaluation of high burnup structure in UO₂ with nanometer resolution

Abstract

The mechanical properties of a well-characterized irradiated light water reactor fuel pin with an average burnup of 72 MWd/kgU were investigated by utilizing nano-indentation technique. Young's modulus and hardness are reported as functions of radial positions covering from mid radial position in the urania pellet to high burnup structure, fuel-cladding chemical interaction zone and zirconium-based cladding. Here, by probing microstructure of the high burnup zone, the mechanical properties of sub-grains and the interaction between them were examined at the nanometer scale. Force-displacement curves from each of these individual sub-grains suggest they resemble single crystal UO₂. However, these restructured grains are weakly bonded to their neighbors.

Evaluation of the Effect of Burnup Acceleration on UO₂ Microstructure Evolution

Technical Report Cheniour, Amani ; Godsey, Kara ; Wallen, Zane ; ...

Accelerated fuel qualification (AFQ) is a methodology by which new nuclear fuels are developed in an accelerated time frame compared with historical fuel qualification approaches. AFQ generally relies on high-fidelity physics-based modeling and simulation tools to adequately describe fuel performance as well as on revolutionary methods to accelerate burnup accumulation and collect relevant data more quickly. This report summarizes the use of advanced fuel modeling and simulation tools to evaluate microstructures from commercially irradiated fuel and microstructures from proposed MiniFuel irradiations, in which burnup accumulation is accelerated while prototypic temperature conditions are maintained. In this milestone, we used the mesoscalemore »« less

High frequency acoustic microscopy for the determination of porosity and Young's modulus in high burnup uranium dioxide nuclear fuel

Conference Marchetti, M. ; University of Montpellier, IES, UMR 5214, F-34000, Montpellier ; Laux, D. ; ...

During irradiation UO{sub 2} nuclear fuel experiences the development of a non-uniform distribution of porosity which contributes to establish varying mechanical properties along the radius of the pellet. Radial variations of the porosity and of elastic properties in high burnup UO{sub 2} pellet can be investigated via high frequency acoustic microscopy. Ultrasound waves are generated by a piezoelectric transducer and focused on the sample, after having travelled through a coupling liquid. The elastic properties of the material are related to the velocity of the generated Rayleigh surface wave (VR). A 67 MWd/kgU UO{sub 2} pellet was characterized using the acousticmore »« less
A Fission Gas Release Model for High-Burnup LWR ThO{sub 2}-UO{sub 2} Fuel

Journal Article Long, Yun ; Yuan, Yi ; Kazimi, Mujid S ; ... - Nuclear Technology

Fission gas release in thoria-urania fuel has been investigated by creating a specially modified FRAPCON-3 code. Because of the reduced buildup of {sup 239}Pu and a flatter distribution of {sup 233}U, the new model THUPS (Thoria-Urania Power Shape) was developed to calculate the radial power distribution, including the effects of both plutonium and {sup 233}U. Additionally, a new porosity model for the rim region was introduced at high burnup. The mechanisms of fission gas release in ThO{sub 2}-UO{sub 2} fuel are expected to be essentially similar to those of UO{sub 2} fuel; therefore, the general formulations of the existing fissionmore »« less
Evaluation of BISON's Transient Fission Gas Release Model on High-Burnup UO₂ MiniFuel

Technical Report Cheniour, Amani ; Capps, Nathan ; Pastore, Giovanni

BISON's fission gas release (FGR) model has been evaluated and tested over several hypothetical thermal transient cases at high burnup and validated against FGR experimental data from an annealing test at high burnup. Diffusion-controlled FGR is accounted for in the model by including several physical mechanisms such as the diffusion of fission gas to grain faces, grain boundary sweeping, grain growth, and intergranular bubble growth. Under temperature variations, FGR is increased due to the development of micro-cracks at grain faces. This existing transient capability, however, was developed based on transient fuel behavior during power ramps and the associated micro-cracking process.more »« less

Clarification of rim structure effects on properties and behaviour of LWR UO{sub 2} fuels and gadolinia doped fuels

Conference Sonoda, T ; Kameyama, T ; Sasahara, A ; ...

At the peripheral region of high burnup fuel pellets, a crystallographic re-structuring is observed, commonly called the 'rim structure', which is characterized by the existence of highly dense small sub-grains, whose size is approximately 100 nm, and the accumulation of small pores with average size around 1 {mu}m. This restructuring can influence the fuel performance including, e.g. fission gas release behaviour, temperature, hardness and density. In order to clarify the threshold burnup and temperature of rim structure formation and fuel performances of LWR UO{sub 2} fuels and gadolinia-doped ((U,Gd)O{sub 2}) fuels whose usage is increasing for higher burnup in LWR,more »« less
