Publikováno v: Procedia Structural Integrity. 19:346-361
Multi-purpose canisters (MPCs) are being employed for dry canister storage of spent fuel at nuclear plant sites as a temporary approach until an interim or permanent dry storage site(s) is available. For storage in coastal or lakeside regions and eve

Helium tribology of Inconel 617 subjected to laser peening for high temperature nuclear reactor applications
Autor: Keivan Davami, Lloyd A. Hackel, Ali Beheshti, Andreas A. Polycarpou, Vasilis Tsigkis, Saifur Rahman
Publikováno v: Applied Surface Science. 577:151961
Inconel 617 is among the best candidates for utilization in high temperature gas cooled reactor tribo-components. However, the combined effects of sliding contact, along with intermittent idle times and very high temperature material degradation, det

Autor: C. Brent Dane, Jon E. Rankin, Gareth Thomas, Lloyd A. Hackel, Pierre Oneid, William A. Neuman, Matt Walter, Fred Bidrawn
Publikováno v: Volume 8: Operations, Applications, and Components.
By generating very deep levels of compressive stress, laser peening can eliminate stress corrosion cracking of materials of use in the nuclear industry; tested materials include Alloys N06600 (Inconel 600), N06690 (Inconel 690), N06022 (Alloy C22) an

Laser shock peening and its effects on microstructure and properties of additively manufactured metal alloys: a review
Autor: Lloyd A. Hackel, Ali Beheshti, Ali Tajyar, Keivan Davami, Michael Munther, Tyler Martin
Publikováno v: Engineering Research Express. 2:022001
This review paper discusses the recent progress in laser shock peening (LSP) of additively manufactured (AM) parts. LSP is an advanced post-processing technique that optimizes the service lives of critical components for various applications by induc

Publikováno v: ASCE-ASME J Risk and Uncert in Engrg Sys Part B Mech Engrg. 4
In the present study, a general probabilistic design framework is developed for cyclic fatigue life prediction of metallic hardware using methods that address uncertainty in experimental data and computational model. The methodology involves: (i) fat
