Summary
This standard specifies the principles of design parameters, material selection, selection of piping components, hydraulic calculation, piping arrangement and hanger design of conventional water vapor pipelines in PWR nuclear power plant. This standard applies to the 1000MW level and below the capacity of the second generation of improved PWR nuclear power units in the conventional island within the soda pipeline design, other PWR nuclear power unit conventional island soda pipeline design can refer to the implementation. This standard does not apply to the design of the following pipes in the conventional island of nuclear power plants: water supply and drainage pipelines; fire water pipes; soda pipelines containing radioactive media;
