本报告提供了与核电厂安全相关管道系统的物理设计、施工、运行和改造相关的成本数据。这些成本是地震烈度和新建和运营电厂建设时间的函数。它还包括一些拟议的简化抗震设计和施工方案的成本效应。成本分析包括管道系统和支架以及材料、制造和安装的工程成本。涵盖了三个建筑时代:1966年至1974年年中、1974年年中至1980年和1981年至1990年。其中包括这些年份工厂的当前管道系统更换和改造成本以及原始建设成本。 管道的抗震设计和施工成本也以总工厂成本的百分比和两个地震设计加速度水平给出:0.1 g OBE-PGA和0.3 g OBE-PGA。所提供的数据来自现有文献以及这些数据的外推。本文件——第426号WRC公告的出版由焊接研究委员会压力容器研究委员会赞助。

This report presents cost data associated with the physical design, construction, operation and modification of nuclear power plant safety-related piping systems. These costs are given as a function of seismic intensity and time period of construction for new and operating plants. It also includes the cost effect of a number of proposed simplified seismic design and construction initiatives.Included in the cost analyses are the engineering costs for both the piping systems and supports and of material, fabrication and installation. Three eras of construction are covered: 1966 to mid-1974, mid-1974 to 1980, and 1981 to 1990. Included are current piping system replacement and modification costs for plants of these vintages as well as the original construction costs. The cost of seismic design and construction of piping is also given as a percentage of overall plant cost and two levels of seismic design acceleration: 0.1 g OBE-PGA and 0.3 g OBE-PGA. The data presented are taken from the existing literature plus extrapolation of these data.Publication of this document - WRC Bulletin No. 426 was sponsored by the Pressure Vessel Research Council of the Welding Research Council, Inc.
