Abstract

Background

Development of a two-component nuclear power system with a closed nuclear fuel cycle based on new-generation fast reactors represents an important task put forward in the Strategy for the Development of Nuclear Power in the Russian Federation until 2050.

Aim

To generalize the results of developments for the project of a new generation commercial power unit with a BN-1200M reactor and to substantiate innovative engineering solutions for its equipment and systems.

Materials and methods

The BN-1200M project uses both reference engineering solutions that have proven themselves well during the operation of BN-600 and BN-800 power units and advanced solutions for the core, main circulation pumps, steam generator, cold traps, reloading system, and layout of the primary and secondary circuit equipment. The current work is focused on the justification of mixed uranium-plutonium fuel, design of the emergency heat removal system, operational safety, manufacturing technology for structural elements of a two-module vessel steam generator, new structural materials, etc.

Results

An engineering design for a sodium-cooled BN-1200M fast neutron reactor has been developed; the competitiveness of the project has been substantiated; design materials for the power unit have been developed. The results of R&D on selecting emergency core protection using passive equipment in the emergency heat removal system for natural circulation along the circuits and justifying new structural materials in heat exchange equipment have increased the level of safety, reliability, and cost-effectiveness of the BN-1200M reactor as compared to previous projects and promising energy sources.

Conclusion

The completed work became a transition to the commercial development of the designed power unit with a high-power BN-1200M reactor plant in a two-component nuclear power system. This stage of commercial development solves the urgent task of completing the experimental validation of engineering solutions for equipment, including the development and testing of prototypes on sodium benches.

BN-1200M项目现状:回顾
发展以新一代快堆为基础的封闭式核燃料循环双组份核电系统是《俄罗斯联邦至2050年核电发展战略》提出的一项重要任务。目的总结BN-1200M反应堆新一代商业发电机组项目的开发成果,并为其设备和系统提供创新的工程解决方案。材料和方法:BN-1200M项目采用了BN-600和BN-800发电机组运行过程中行之有效的参考工程解决方案,以及堆芯、主循环泵、蒸汽发生器、冷阱、再装填系统和一次、二次回路设备布置的先进解决方案。目前的工作重点是铀-钚混合燃料论证、应急排热系统设计、运行安全性、双模容器蒸汽发生器结构元件制造技术、新型结构材料等方面的工作。结果开展了钠冷BN-1200M快中子堆工程设计;项目的竞争力得到证实;动力装置的设计材料已经开发出来。在沿回路自然循环的应急排热系统中选择使用无源设备的应急堆芯保护以及在换热设备中使用新型结构材料的研发结果,与以前的项目和有前景的能源相比,提高了BN-1200M反应堆的安全性、可靠性和成本效益水平。结论本工程的完成为双组份核电系统大功率BN-1200M堆电厂设计的动力机组的商业化开发提供了过渡。这一阶段的商业开发解决了完成设备工程解决方案实验验证的紧迫任务,包括在钠台上开发和测试原型。
