Creep-fatigue damage for a structure with dissimilar metal welds of modified 9Cr-1Mo steel and 316L stainless steel
TL;DR: In this paper, a creep-fatigue test with a structural specimen made of Mod. 9Cr-1Mo steel and 316L stainless steel has been carried out and the test results were compared with those of the evaluations by the high temperature design codes of ASME subsection NH and RCC-MR to quantify the conservatism.
Journal ArticleDOI
Investigation of ratcheting characteristics of modified 9Cr–1Mo steel by using the Chaboche constitutive model
Gyeong-Hoi Koo,Jae-Han Lee +1 more
TL;DR: In this article, an inelastic constitutive equation of the Chaboche model, which can simulate ratcheting behavior at high temperatures, is investigated for modified 9Cr-1Mo steel.
Journal ArticleDOI
Conceptual design of the sodium-cooled fast reactor kalimer-600
Dohee Hahn,Yeong-Il Kim,Chan Bock Lee,Seong-O Kim,Jae-Han Lee,Yong-Bum Lee,Byung-Ho Kim,Hae-Yong Jeong +7 more
TL;DR: The Korea Atomic Energy Research Institute has developed an advanced fast reactor concept, KALIMER-600, which satisfies the Generation IV reactor design goals of sustainability, economics, safety, and proliferation resistance.
Journal ArticleDOI
Thermal ratchetting deformation of a 316L stainless steel cylindrical structure under an axial moving temperature distribution
TL;DR: In this paper, a structural test of a 316L stainless steel cylinder was carried out to simulate the thermal ratchetting behavior occurring at the thermal liner of a liquid metal reactor as a free surface of a hot sodium pool moves up and down under plant heat-up, cool down conditions and other thermal transients.

Integrated horizontal and vertical seismic isolation bearing
TL;DR: In this article, a seismic isolation bearing device is described in which a laminated elastic rubber-steel bearing adapted to isolate horizontal seismic loading cooperates with a vertical isolation device employing a compression spring, or equivalent device, effective for isolating vertical seismic loadings.
