description: The given work is devoted to solving the problem of reducing heat loads on divertor plates and considering the efficiency of krypton compression in the divertor region in comparison with other impurities. Nowadays, impurity seeding is necessary to reduce the heat loads on the divertor. The impurity begins to radiate (the radiation is scattered isotropically), taking energy from the plasma electrons, thus reducing the heat flux (in the electronic channel). Via the SOLPS-ITER code, modeling of ASDEX Upgrade scrape-off layer plasma with krypton seeding was carried out. We considered three variants with different puff rates: 4e16 c^(-1), 4.2e18 c^(-1), 3e19 c^(-1). To analyze the efficiency of krypton compression the cases with the same puff rate, but with other impurities seeding (N, Ne, Ar) were considered. It was shown that the impurity concentration in the equatorial plane is smaller in case with krypton puffing, which is an indicator of compression. Compression is directly related to the length of ionization â the shorter the length, the better the compression. For the case with 4.2e18 c^(-1) puff rate also a case with argon with a rateÂ  1e19 c^(-1) was considered. These cases demonstrate the same percentage of radiation, which is 50 percent. In this series of casesÐ± it was demonstrated that the compression of krypton for this regime is higher than the compression of argon.
