Review of Anchorage Systems for Externally Bonded FRP Laminates
Grelle, Stephen V.,Sneed, Lesley H. Korea Concrete Institute 2013 International Journal of Concrete Structures and M Vol.7 No.1
The most recent report by ACI Committee 440 on externally bonded fiber reinforced polymer (FRP) strengthening systems states that systems designed to mechanically anchor FRP should be studied in detail and substantiated by physical testing. To select and design an appropriate anchorage system for use in an FRP strengthening system, it is important that findings from previous research studies be known. This paper presents a comprehensive literature review of the performance of different mechanical anchorage systems used in FRP strengthening applications. Each anchorage system is discussed in terms of its purpose and performance. Advantages and disadvantages of each system are discussed, and areas in need of future research are explored.

Advanced Reactor Passive System Reliability Demonstration Analysis for an External Event
Matthew Bucknor,David Grabaskas,Acacia J. Brunett,Austin Grelle 한국원자력학회 2017 Nuclear Engineering and Technology Vol.49 No.2
Many advanced reactor designs rely on passive systems to fulfill safety functions duringaccident sequences. These systems depend heavily on boundary conditions to induce amotive force, meaning the system can fail to operate as intended because of deviations inboundary conditions, rather than as the result of physical failures. Furthermore, passivesystems may operate in intermediate or degraded modes. These factors make passivesystem operation difficult to characterize within a traditional probabilistic framework thatonly recognizes discrete operating modes and does not allow for the explicit considerationof time-dependent boundary conditions. Argonne National Laboratory has been examiningvarious methodologies for assessing passive system reliability within a probabilistic riskassessment for a station blackout event at an advanced small modular reactor. This paperprovides an overview of a passive system reliability demonstration analysis for an externalevent. Considering an earthquake with the possibility of site flooding, the analysis focuseson the behavior of the passive Reactor Cavity Cooling System following potential physicaldamage and system flooding. The assessment approach seeks to combine mechanistic andsimulation-based methods to leverage the benefits of the simulation-based approachwithout the need to substantially deviate from conventional probabilistic risk assessmenttechniques. Although this study is presented as only an example analysis, the resultsappear to demonstrate a high level of reliability of the Reactor Cavity Cooling System (andthe reactor system in general) for the postulated transient event.

Planar organic spin valves using nanostructured Ni<sub>80</sub>Fe<sub>20</sub> magnetic contacts
AlQahtani, H.,Bryan, M.T.,Hayward, T.J.,Hodges, M.P.,Im, M.Y.,Fischer, P.,Grell, M.,Allwood, D.A. Elsevier Science 2014 Organic Electronics Vol.15 No.1
Planar organic spin valves were fabricated by evaporating organic semiconductor PTCDI-C<SUB>13</SUB> onto pairs of patterned Ni<SUB>80</SUB>Fe<SUB>20</SUB> magnetic nanowires separated by 120nm. Control over the relative alignment of magnetisation in the nanowires was achieved by including a domain wall 'nucleation pad' at the end of one of the wires to ensure a large separation in magnetic switching fields. Switching behaviour was investigated by optical and X-ray magnetic imaging. Room temperature organic magnetoresistance of -0.35% was observed, which is large compared to that achieved in vertical spin valves with similar materials. We attribute the enhanced performance of the planar geometry to the deposition of the semiconductor on top of the metal, which improves the quality of metal-semiconductor interfaces compared to the metal-on-semiconductor interfaces in vertical spin valves.
