Abstract

The results of high gradient magnetic filter (HGMF) model tests for coolant cleaning on a channel high power reactor multiple forced circulation line are presented. This coolant (water) was cleaned from iron and radionuclide corrosion products. The extracted particle size was 0.1-5 μm. Numerous experiments showed that the average efficiency for the nuclides ⁹⁵Nb, ⁹⁵Zr, and ⁶⁰Co was equal to 95-99% in cases when their initial radioactivity was more than 10^-7 Cu/l, most of them being extracted at the filter inlet. The obtained results show that this type of HGMF is better than the iron ball magnetic filter because the product quality and specific capacity are higher
