“…Calculations show that during 122 h, pressure under the containment can raise up to 0.7 MPа, with the steam/air ratio being 2.7:1 [17]. This time is enough for the steam-air mass containing volatile radioactive fission products to penetrate (0.3% to 3% a day) into the intercontainment area and then into the environment.…”

The paper reports some technical solutions, which suggested or used for increasing of environmental protection during accidents at NPPs. For NNPs with two protective shells and pressure release system such as WWER-1000 a comprehensive, passive-mode environmental protection system of decontamination of the radioactive steam-air mixture from the containment and the intercontainment area was suggested. This system includes the "wet" stage (scrubbers, etc.), the "dry" stage (sorption module), and also an ejector, which in a passive mode is capable of solving the multi-purpose task of decontamination of the air-steam mixture. For WWER-440/230 NPPs three protection levels: 1) a jet-vortex condenser; 2) the spray system; 3) a sorption module were suggested and installed. For modern designs of new generation NPPs, which do not provide for pressure release systems, a new passive filtering system together with the passive heat-removal system, which can be used during severe accidents in case all power supply units become unavailable, was proposed and after modernization was installed at the KudanKulam NPP (India).

“…Calculations show that during 122 h, pressure under the containment can raise up to 0.7 MPа, with the steam/air ratio being 2.7:1 (Dillman, 1991). This time is enough for the steam-air joint containing volatile radioactive fission products to penetrate (0.3 to 3 % per day) into the intercontainment area and then into the environment.…”
