以中国改进型三环路压水堆(CPR1000)堆内构件的螺栓联接拧紧力矩作为问题研究的出发点,探讨堆内构件的螺栓联接件翻版设计中,以国标米制替代统一英制的具体步骤和方法,列出了在转化设计中必须考虑的影响螺栓联接拧紧力矩大小的螺栓结构要素,以确保CPR1000堆内构件螺栓联接结构的可靠性,避免在反应堆运行过程中因螺栓联接结构的松动或紧固件脱落而威胁到反应堆的安全运行.
以中國改進型三環路壓水堆(CPR1000)堆內構件的螺栓聯接擰緊力矩作為問題研究的齣髮點,探討堆內構件的螺栓聯接件翻版設計中,以國標米製替代統一英製的具體步驟和方法,列齣瞭在轉化設計中必鬚攷慮的影響螺栓聯接擰緊力矩大小的螺栓結構要素,以確保CPR1000堆內構件螺栓聯接結構的可靠性,避免在反應堆運行過程中因螺栓聯接結構的鬆動或緊固件脫落而威脅到反應堆的安全運行.

To ensure the reliability and safety of the screw connection in reactor operation, the screw tightening torque of CPR1000 internals is as a start for the study. The step and method for replacing the inch screw by meter screw in the transformation design of CPR1000 internals is discu.ssed, and screw structural elements which have influence on screw tightening torque are given in this paper.
