核动力舰船生物屏蔽不同陆上核动力装置生物屏蔽,其重量、体积受到极大限制,屏蔽空间也极度不规则。如何设计出经济上合理、技术上可行、体积小、重量轻、相对性能最佳的生物屏蔽,是一项复杂的系统工程。本文概述了核动力舰船生物屏蔽设技术的特点和要求;总结了核动力舰船生物屏蔽设计的一般方法、设计流程和生物屏蔽材料研制及应用情况;提出了将点核积分法同蒙特卡罗方法相结合的核动力舰船生物屏蔽设计方法,可为核动力舰船生物屏蔽设计提供参考。
The biological shielding of nuclear power naval ship is different from the biological shielding of nuclear power reactor on land.The weight and volume of the biological shielding is greatly restricted. The shielding space is extemely irregular. How to design economically reasonable, technically feasible, small volume, light weight, relative performance best biological shielding is a complex system engineering. This paper gives characteristics and requirements about biological shielding design of nuclera power naval ship; Summarizes the general method of biological shielding, process of biological shielding design, study and application of biological shielding mateiral; proposes integrated Monte-Carlo method and Poine-kernel integral method for the biological shielding of nuclera power naval ship. This paper can give some reference to the biological shielding of nuclear power naval ship design.
