Advances and Perspectives in Nuclear Thermal Hydraulics and Nuclear Safety

Dear Colleagues,

Significant advancements in nuclear thermal hydraulics and safety have been achieved in recent years by introducing novel computational techniques. These include methodologies such as Computational Fluid Dynamics (CFD), uncertainty quantification, and artificial intelligence.

CFD produces high-fidelity results that enhance the understanding of flow configuration and heat exchange, ultimately allowing for reduced safety margins. These capabilities have been integrated with state-of-the-art system thermal hydraulic codes to improve the prediction of system transients and accident scenarios.

Uncertainty quantification has become increasingly important for assessing the reliability of models and simulations. By accounting for uncertainties, engineers can better predict reactor behavior under various conditions, thereby improving safety and design robustness.

Artificial Intelligence (AI) has emerged as a powerful tool in nuclear thermal hydraulics, enhancing predictive capabilities and optimizing reactor operations and safety assessments. Machine learning algorithms analyze vast datasets to improve simulation accuracy and the efficiency of reactor simulation tools. AI-driven models can forecast potential issues before they arise, significantly boosting safety and operational reliability.

These advanced tools have been successfully integrated into studies of operational and developmental fission reactors, as well as in the design of novel next-generation fission and fusion reactor technologies.

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 250 words) can be sent to the Editorial Office for assessment.

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. Applied Sciences 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 2400 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.
