摘　　要：福岛事故后,为进一步提高核电厂核安全水平,主要核电国家和组织正在开展新核安全目标和理念的研究。本文结合当前国际上核安全要求的发展趋势,对"设计扩展工况"(Design Extension Conditions,简称DEC)这一概念进行了初步探讨,主要包括其意义、内涵、可接受准则、对纵深防御原则的影响,以及设计扩展工况安全设施的设计要求等,希望为国内建立新的核安全要求起到抛砖引玉的作用。After Fukushima Dai-ichi nuclear accident, new nuclear safety objectives and principles are being studied in main nuclear power countries and organizations, to further improve the safety level of nuclear power plant. In this paper, a preliminary discussion on the concept of design extension condition （ DEC ） was conducted, mainly including its significance, connotation, acceptance criteria, the influence on the defense in depth principle, and design requirement of DEC safety featuresetc. This study may be valuable in the development of domestic new nuclear safety reauirements
