1模型评估参数的选择目前,在消防领域,国内外有一种发展趋势,即将基于风险的性能化评估引入到防火工程实践中。这种趋势不仅存在于一般的防火领域,也存在于核电厂防火领域。2002年,美国消防协会(NFPA)颁布了NFPA 805-2001《轻水反应堆发电厂防火装置性能化消防标准(2001版)》(以下简称NFPA 805)。2004年7月,美国核监管委员会(NRC)修改了美国联邦法规第10条,50.48节关于防火保护的内容,允许反应堆授权方 Selection of Model Evaluation Parameters At present, there is a trend in the field of fire protection both at home and abroad. That is, risk-based performance evaluation is introduced into fire prevention engineering practice. This trend exists not only in the general field of fire prevention, but also in the field of nuclear power plant fire prevention. In 2002, the National Fire Protection Association (NFPA) promulgated NFPA 805-2001 Performance Standardization of Fire Protection Systems for Light-Water Reactor Power Plants (2001 Edition) (NFPA 805). In July 2004, the U.S. Nuclear Regulatory Commission (NRC) amended Article 10 of the US Code of Federal Regulations, Section 50.48 on fire protection, allowing reactor licensees
