Abstract

MELCOR is a computer code for the simulation and safety analysis of nuclear facilities, comprising several modules for the calculation of thermal–hydraulic phenomena and aerosol physics. However, MELCOR offers limited support for interactive control, such as valve opening or flow rates redefinition, as its batch execution mode does not allow real-time modification of model parameters. To overcome this limitation, we present MELGYM, a Gymnasium-based interface that facilitates interactive control in MELCOR. MELGYM enables the training of reinforcement learning agents on MELCOR simulations, introducing real-time interaction and enabling the definition of reward functions based on simulation outcomes.

MELGYM: MELCOR仿真的动态控制界面

MELCOR是一个用于核设施模拟和安全分析的计算机代码，包括几个用于计算热水力现象和气溶胶物理的模块。然而，MELCOR提供了有限的交互式控制支持，如阀门开度或流量重新定义，因为它的批量执行模式不允许实时修改模型参数。为了克服这一限制，我们提出了MELGYM，这是一个基于体育馆的界面，可以促进MELCOR中的交互控制。MELGYM可以在MELCOR模拟上训练强化学习代理，引入实时交互，并根据模拟结果定义奖励函数。

期刊介绍： SoftwareX aims to acknowledge the impact of software on today''s research practice, and on new scientific discoveries in almost all research domains. SoftwareX also aims to stress the importance of the software developers who are, in part, responsible for this impact. To this end, SoftwareX aims to support publication of research software in such a way that: The software is given a stamp of scientific relevance, and provided with a peer-reviewed recognition of scientific impact; The software developers are given the credits they deserve; The software is citable, allowing traditional metrics of scientific excellence to apply; The academic career paths of software developers are supported rather than hindered; The software is publicly available for inspection, validation, and re-use. Above all, SoftwareX aims to inform researchers about software applications, tools and libraries with a (proven) potential to impact the process of scientific discovery in various domains. The journal is multidisciplinary and accepts submissions from within and across subject domains such as those represented within the broad thematic areas below: Mathematical and Physical Sciences; Environmental Sciences; Medical and Biological Sciences; Humanities, Arts and Social Sciences. Originating from these broad thematic areas, the journal also welcomes submissions of software that works in cross cutting thematic areas, such as citizen science, cybersecurity, digital economy, energy, global resource stewardship, health and wellbeing, etcetera. SoftwareX specifically aims to accept submissions representing domain-independent software that may impact more than one research domain.
