Abstract

In this paper the SOLUBLE IMPURITY DISTRIBUTION in a PGV-1000 steam generator has been analyzed. A PGV-1000 steam generator is a horizontal one with 750 MW thermal powers that produces 1467 t/h steam. In this paper a two-dimensional model is proposed to simulate the SOLUBLE IMPURITY DISTRIBUTION in the SG. It is shown that the model can estimate the impurity distribution with an error within 13%, in longitudinal direction, and within 35%, in traverse direction, of maximum impurity. With this model, various feed-water and blow-down systems are investigated. The calculated results show that the soluble impurity in a PGV-1000 steam generator can be considerably reduced. The computation results show that, in a standard feed-water and blow-down system, the average impurity can be reduced from about 100 times the impurity of the FEED WATER to about 25 times, and that the maximum impurity can be reduced from 270 to 180. And in the improved feed-water and blow-down system for PGV-1000 with a modification to the FEED WATER system the impurity can be reduced 40% approximately.
