en.Wedoany.com Reported, On March 24, 2026, the "Exchange Seminar on Calorific Value Data of Combustibles in Nuclear Power Plants", organized by the Nuclear Safety Branch of the Chinese Nuclear Society and hosted by the Nuclear and Radiation Safety Center of the Ministry of Ecology and Environment (hereinafter referred to as the Nuclear Safety Center) and China Nuclear Power Engineering Co., Ltd., was successfully held in Shenzhen. More than 40 expert representatives from 16 organizations participated, including China Nuclear Power Engineering Co., Ltd., Shanghai Nuclear Engineering Research and Design Institute Co., Ltd., CNNC Energy Technology Co., Ltd., China Institute of Atomic Energy, Hualong International Nuclear Power Technology Co., Ltd., Suzhou Nuclear Power Research Institute Co., Ltd., Shanghai Fire Research Institute of the Ministry of Emergency Management, Guangzhou Building Materials Research Institute, Taishan Nuclear Power Joint Venture Co., Ltd., and Guangxi Fangchenggang Nuclear Power Co., Ltd. Zhang Chunming, Chief Engineer of the Nuclear Safety Center, attended the event.

Calorific value data of combustibles is a key fundamental parameter for fire extinguishing system design, fire hazard analysis, and combustible material management. During the meeting, participating organizations introduced the current status of selecting calorific value data for combustible materials in engineering design and plant management, while fire research institutions shared relevant standards and methods for calorific value testing. The representatives engaged in in-depth discussions on current data discrepancies and the lack of experimental support for some data, proposing a series of constructive solutions.

This seminar established an open and professional platform for industry exchange. It not only systematically reviewed the current situation but also fostered an industry consensus on "the necessity of strengthening the autonomy of fundamental data." The outcomes of the meeting will provide important guidance for subsequent specialized testing, filling data gaps, and building a foundational data system for fire safety in Chinese nuclear power plants.
