Special Issue Information
Dear Colleagues,
The degradation processes of alloys’ mechanical properties after neutron irradiation represent important issues for studies from a scientific and an industrial point of view. The wide scope of alloys used at nuclear power plants or experimental nuclear installations (including ITER or spallation source) is facilitated by neutrons of different energies, fluxes, or fluences. In fact, many nuclear facilities try to operate beyond projected lifetime, and processes such as plant lifetime management (PLIM) or plant lifetime expension (PLEX) are widely used at scientific or industrial conferences and papers. Lifetime expension is considered in over 50% of projected values. In connection to regular power upgrades of these installations, the neutron load of design steels and alloys has substantially increased. Typical representatives could include the VVER reactor type, which is the most distributed type in the world, with a lifetime level of 60+. The protection of sufficient safety margins for the long-term operation of a wide scope of nuclear installation should be based on the deep understanding of physics and metallurgy.
The theoretical and experimental analysis, neutron irradiation (experimental or in real conditions), simulation, verification, and validation of codes and processes, as well as the proper and plausible interpretation of achieved results towards new findings and conclusions supporting new knowledge in the area of properties of alloys after neutron irradiation, will be the main scope of this Special Issue. Applications for the nuclear industry directed to the long-term safe operation of nuclear installations are welcomed.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
