A silica gel-based system that demonstrates cost-effectiveness, stability and easy maintenance, is proposed, and the corresponding simulations are performed in this study. With the system, depressurization and CHF enhancement can be simultaneously realized. Several parameters such as the particle size, initial steam partial pressure and containment free volume on the steam removal efficiency are considered to assess the overall applicability of the system to nuclear power plants. The adsorption process becomes saturated in relatively short periods, and peak pressures by ejected high-temperature steam can be mitigated thereby. Besides, the silica gel-based system will show great functionality, especially for the small-sized reactors.

提出了一种具有成本效益、稳定性和易于维护的硅胶基系统，并在本研究中进行了相应的模拟。该系统可以同时实现降压和CHF升压。考虑了几个参数，如颗粒大小、初始蒸汽分压和蒸汽去除效率的安全壳自由体积，以评估系统对核电站的整体适用性。吸附过程在相对较短的时间内达到饱和，从而可以减轻喷射高温蒸汽的峰值压力。此外，基于硅胶的系统将显示出强大的功能，特别是对于小型反应器。
