Background

This Research Topic focuses on nuclear energy, including nuclear fuels, nuclear thermal hydraulics, nuclear power plant (NPP) severe accident, core sub-channel, generation IV NPP concept design, experiment two-phase flow, computation fluid dynamics simulation, and applications of new methods (such as artificial neural networks). These areas of study are devoted to improving the current understanding of heat and mass transfer, and fluid mechanics processes during nuclear industry application.

Nuclear fuels mainly include fuels and cladding materials, fuels and cladding structure, mechanical engineering, stress-strain, plastic deformation of fuels and cladding, oxidation of cladding, accident tolerance fuels materials development and thermal physical properties evaluation. Nuclear Thermal hydraulics mainly means NPP system thermal hydraulic analysis, including normal operation, beyond design basis accident and so on. NPP severe accident mainly include fuels and cladding materials candling, fuel-coolant interaction(FCI), debris bed heat transfer, core flow channel blockage, formation of melting pool, melt core and concrete interaction (MCCI). Core sub-channel means 2D analysis of NPP cores, to reveal the temperature and flow distribution in the core. Generation IV NPP concept design include very-high temperature reactor (VHTR), molten salt reactor (MSR), supercritical water cooled reactor (SCWR), gas cooled fast reactor (GFR), sodium cooled fast reactor (SFR), lead cooled fast reactor (LFR). Accelerator driven subcritical reactor can also be included. Experiment two-phase flow include the studying on heat transfer coefficient, nuclear critical heat flux in different nuclear industry structure. Computation fluid dynamics simulation means using CFD method to study nuclear projects. Applications of new methods is an inter-discipline, providing more opportunities to solve engineering problems in nuclear industry.

In this Research Topic, nuclear fuels, nuclear thermal hydraulics, nuclear power plant (NPP) severe accident, core sub-channel, generation IV NPP concept design, experiment two-phase flow, computation fluid dynamics simulation, and applications of new methods are all welcomed. Other topics not included but around these regions are also welcomed.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

• Who leads a Research Topic? 

  A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

  The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

• What is the role of a topic editor?

  As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

   

  You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

• What support will I receive when editing a new Research Topic? 

  As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).

• As a junior researcher, can I be involved in editing a Research Topic? 

  If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.
