Analysis on the Auxiliary Process System of Site Laboratory in Nuclear Power Plant

Key words: 
• site laboratory in nuclear power plant /
• low-level slightly radioactive-sewage /
• radiation zoning

Abstract: [Introduction] The site laboratory in nuclear power plant is the important technology building,and the auxiliary process system served is also important to provide the better process system design. [Method] This article took the site laboratory in Hongyanhe nuclear power plant as an example,and discussed the auxiliary process system. [Result] The results summarize the layout principles of radiation zoning according to the characters and source of the sample, and the system which for being slightly radioactive-sewage recovery and the design principles of piping layout and so on. [Conclusion] This article provides the useful experience for the process system design of site laboratory in nuclear power plant in the future.
