National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Performance test of condensate polishing system for Qinshan Nuclear Power Plant.

DE96618364

Publication Date	1995
Personal Author	You Zhaojin, ; Qian Shijun, ; Lu Ruiting,
Page Count	9
Abstract	The flow chart, resin performance and water quality specifications of the condensate polishing system for Qinshan Nuclear Power Plant (QNPP) are briefly described. The initial regeneration process and the following service of the condensate polishing system are introduced. And the ability to remove corrosion products and ionic impurities of the condensate polishing system are verified during start-up, normal power operation and condenser leakage of the plant. The result shows that the performance of condensate polishing system in QNPP can completely meet the design requirements. Especially during the start-up of the unit or the leakage of the condenser, despite the inlet water quality of the polishers is far worse than the specified standard, the outlet water quality is still controlled within the indexes. Finally, several existing problems, such as 'volume ratio between resins is not optimum' and 'the inert resin and anion resin can not be stratified completely', in the condensate polishing system are also discussed. (4 refs., 1 fig., 8 tabs.). (Atomindex citation 27:026199)
