Special Issue Information
Dear Colleagues,
Electrical cables are one of the most important pieces of equipment in terms of both abundance and role inside nuclear power plants (NPPs). It has been estimated that each NPP owns about 1500 km of cables, mainly used for delivering power, control, and measurement signals. Assessing the reliability of these cables is an extremely critical issue for the validation of the possible life extension of NPPs. As is already known, cable health status is strictly related to the condition of the primary insulation, usually made up of polymer-based compounds. In nuclear environments, these latter ones are typically subjected to both thermal and radiochemical aging, which significantly accelerates the degradation of the organic matrix.
This Special Issue aims to give an overview on the most recent advances in damage analysis and lifetime prediction of cables used in nuclear power plants. Selected contributions are invited to provide reviews and analyses of the main polymer degradation mechanisms and their effects on material reliability and properties at various scales (from physical–chemical to mechanical and electrical material behavior). Potential topics include but are not limited to:
- Multiscale analyses of degradation and aging mechanisms inside electrical cables;
- Lab-scale techniques for cable aging assessment;
- Development of non-destructive testing techniques for monitoring the health of cables on site;
- Lifetime prediction and reliability of cables under radiothermal stresses.

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. Energies is an international peer-reviewed open access semimonthly 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.
