The micro-sized graphite dust plays an important role in pebble-bed high temperature gas-
cooled reactors, for the close relation with the fission products (FPs). However, an accurate …

Nuclear-grade graphite is a critically important high-temperature structural material for
current and potentially next generation of fission reactors worldwide. It is imperative to …

Raman spectroscopy has long been used in studying irradiation damage in carbon/graphite
materials. It is however unclear if the measurements from different types of materials are …

Excessive cracking can be a serious durability problem for reinforced concrete structures. In
recent years, addition of microencapsulated phase change materials (PCMs) to concrete …

The aim of this paper is to investigate the fracture performance of cement paste at micro
scale by both experimental and numerical methods. Micro cubic specimens with length of …

Herein, the first study is presented using 4D synchrotron X-ray microtomography to capture
all stages of crack development in neutron irradiated and radiolytically oxidised nuclear …

Nuclear graphite contains defects spanning from nanoscale basal cracks to sub-mm scale
voids. This study aims to establish an experimental method to investigate pre-existing …

Cement paste is the main binding component in concrete and thus its fundamental
properties are of great significance for understanding the fracture behaviour as well as the …

Fatigue strengthening of composites refers to the increase of residual strength after a
specific number of loading cycles. This eccentric behavior widely exists in carbon/carbon …

This work investigated the porosity evolution of POCO ZXF-5Q graphite that has been
irradiated by 340 kW, 120 GeV protons inside NT02 target system in Fermilab's NuMI …
