Hydrogen is having a worldwide momentum as a clean versatile energy solution and this is the time for nuclear hydrogen production technologies to play its role in securing a clean and affordable energy future. For over four decades, several nations have been investigating the potential of tens of thermochemical cycles for efficient and sustainable hydrogen production. These cycles require high quality heat (i.e. heat at high temperatures) solely or along with electric power (i.e. hybrid thermochemical cycles) both of which can be provided by nuclear energy. This paper delivers a highlight on the potential of nuclear energy for hydrogen production. It also discusses the main features of five of the promising thermochemical cycles that are considered for integration with nuclear power plants. Furthermore, the paper highlights the current status and advances of R&D in these thermochemical cycles as well as the economics considering, cost estimation and highlight on the main safety consideration for large-scale nuclear hydrogen production using different nuclear-driver technologies.

氢作为一种清洁的多功能能源解决方案在全球范围内具有发展势头，现在正是核氢生​​产技术在确保清洁和负担得起的能源未来中发挥作用的时候。在过去的四十年中，几个国家一直在研究数十个热化学循环对高效和可持续制氢的潜力。这些循环仅需要高质量的热量（即高温下的热量），或者就需要电能（即混合热化学循环），两者都可以由核能提供。本文重点介绍了核能在制氢方面的潜力。它还讨论了五个有前途的热化学循环的主要特征，这些循环已考虑与核电厂整合。此外，
