Title: Experimental evidence for ‘buckle, ruck and tuck’ in neutron irradiated graphite

Abstract

The current mainstream theory for radiation-induced dimensional change of nuclear graphite is based on the notion that interstitially displaced carbon atoms will coalesce into dislocation loops (i.e., additional basal planes). This standard atomic-displacement model has been challenged by theories based on first principles calculations. The so-called ‘ruck and tuck’ of basal planes has been proposed as an alternative mechanism to explain the observed c-axis expansion under irradiation; however, no such defects have been observed experimentally so far. In this study, the first experimental evidence for the presence of a ‘ruck and tuck’ defect in high-temperature neutron-irradiated nuclear graphite is presented.

A macro-scale ruck and tuck mechanism for deformation in ion-irradiated polycrystalline graphite

Journal Article Liu, Dong ; Cherns, David ; Johns, Steve ; ... - Carbon

A vein structure, which becomes more pronounced with increasing ion dose, was found on the surface of polycrystalline HOPG (highly oriented pyrolytic graphite) implanted by ex situ C+ (up to 1.8 x 10(17) ions/cm(2)), and in situ Ar+ in a transmission electron microscope (TEM). These veins are found to be independent of the crystallographic orientations and are associated with the formation of pores. Underneath the veins, a triangular-shaped core was formed with the graphite platelet inside the core displaced up towards the surface. A macro-scale 'ruck&tuck' geometry was thus generated at these triangle structure boundaries. Progressive movement of dislocations alongmore »« less

Development of a Scanning Microscale Fast Neutron Irradiation Platform for Examining the Correlation Between Local Neutron Damage and Graphite Microstructure

Technical Report Pinhero, Patrick ; Windes, William

The fast particle radiation damage effect of graphite, a main material in current and future nuclear reactors, has significant influence on the utilization of this material in fission and fusion plants. Atoms on graphite crystals can be easily replaced or dislocated by fast protons and result in interstitials and vacancies. The currently accepted model indicates that after most of the interstitials recombine with vacancies, surviving interstitials form clusters and furthermore gather to create loops with each other between layers. Meanwhile, surviving vacancies and interstitials form dislocation loops on the layers. The growth of these inserted layers cause the dimensional increase,more »« less

Fullerene-like defects in high-temperature neutron-irradiated nuclear graphite

Journal Article Johns, Steve ; He, Lingfeng ; Bustillo, Karen ; ... - Carbon

Irradiation-induced defect evolution in graphite is particularly important for its application in graphite-moderated nuclear reactors. The evolution of defects directly influences macroscopically observed property changes in irradiated nuclear graphite which, in turn, can govern the lifetime of graphite components. This article reports novel defect structures and the irradiation response of microstructural features occurring in high-temperature irradiated nuclear graphite IG-110. High resolution transmission electron microscopy (HRTEM) was used to characterize specimens neutron-irradiated at a high temperature (≥ 800°C) at doses of 1.73 and 3.56 atomic displacements per atom (dpa). Concentric shelled and fullerene-like defects were found to result in swelling alongmore »« less

Formation of carbon nanostructures in nuclear graphite under high-temperature in situ electron-irradiation

Journal Article Johns, Steve ; Poulsen, Tyler ; Kane, Joshua J. ; ... - Carbon

Defect evolution in nuclear graphite has been studied in real time using high-temperature in situ transmission electron microscopy. In situ electron-irradiation was conducted at 800 °C on a 200 kV transmission electron microscope with a dose rate, given in terms of displacements per atom per second, of approximately 1.46 × 10^–3 dpa/s. Defect domains consisting of ordered arrangements of pentagons, hexagons, and heptagons exist intrinsically in nuclear graphite and in addition are readily produced via electron-irradiation; however, at elevated temperatures these defect domains undergo atomic rearrangements resulting in the formation of carbon nanostructures via curling and closure of the basalmore »« less

Topological Defects in Graphite under Irradiation using Molecular Dynamics

Journal Article Raj, Anant ; Eapen, Jacob - Transactions of the American Nuclear Society

Graphite is the preferred material for moderating elements and structural components in a Very High Temperature Reactor (VHTR). It has a layered structure with basal planes constituted by carbon atoms arranged in a hexagonal lattice. Graphite accommodates a wide variety of defects such as vacancies, interstitials, and dislocation loops; a detailed description can be found in a review paper by Telling and Heggie. The layered configuration in graphite engenders energetic conditions that favor the formation of topological defects. Unlike the interlayer defects, which often are sp{sup 3} hybridized, topological defects maintain their sp{sup 2} bond connectivity. Several types of topologicalmore »« less
