    • Nuclear power plays a key role as renewable energy in alleviating the worldwide energy shortage. The material degradation caused by high-temperature and high-flux neutron irradiation is the most concerning issue for nuclear reactor safety. A large number of He atoms produced through the (n, alpha) transmutation reaction diffuse and migrate in metals and accumulate to form He bubbles because of the extremely low solubility of He atoms in metal materials. The helium bubbles gather at the grain boundary or grain to cause swelling, hardening, embrittlement, and other damages to the in-core structural components. This paper mainly summarizes the research progress on He irradiation in steel and iron-based alloys, including the diffusion and accumulation of He atoms, the nucleation and growth of He bubbles, and the microstructure and macroscopic degradation of material performance caused by He irradiation. The mechanism of helium irradiation-induced corrosion in steel and iron-based alloys in recent years is reviewed as well. Moreover, the investigations on irradiation performance in additive manufactured stainless steels are summarized, and the mechanism of irradiation resistance is prospected.

  • Approaches and challenges to the study of loess : Introduction to the Loess-Fest Special Issue
  • 2018
  • Ingår i: Quaternary Research. - : Cambridge University Press (CUP). - 0033-5894 .- 1096-0287. ; 89:3, s. 563-618
  • Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
    • In September 2016, the annual meeting of the International Union for Quaternary Research's Loess and Pedostratigraphy Focus Group, traditionally referred to as a LoessFest, met in Eau Claire, Wisconsin, USA. The 2016 LoessFest focused on thin loess deposits and loess transportation surfaces. This LoessFest included 75 registered participants from 10 countries. Almost half of the participants were from outside the United States, and 18 of the participants were students. This review is the introduction to the special issue for Quaternary Research that originated from presentations and discussions at the 2016 LoessFest. This introduction highlights current understanding and ongoing work on loess in various regions of the world and provides brief summaries of some of the current approaches/strategies used to study loess deposits.
