Inside Chernobyl Nuclear Power Plant 2011, Part III: Dosimetry Control RoomAugust 9, 2011
With a decade-plus lead on the rest of the RBMK fleet in confronting the uncertainties of the decommissioning process, which involves fuel movements and the continuing generation of radioactive wastes, Chernobyl Nuclear Power Plant must continue to remain particularly vigilant on matters of radiation safety. There is a well-maintained underground bunker at the ABK-1 administrative building that serves as a modern emergency operations center, for example. This year we visited the Phase I dosimetry control room as part of our tour, where a dosimetrist monitors radiation levels and aerosol levels in the rooms of the Unit 1 and Unit 2 complex, and monitors discharge of radioactivity from the operational VT-1 ventilation stack. The dosimetry control room is accessed from the +10-meter deaerator corridor, between Unit 1 and Unit 2 reactor buildings.

To compare and contrast facilities at Chernobyl with those at an operational RBMK-1000 plant, please see jencha’s wonderful recent photodiary from the Kursk NPP (the 12th photo shows the dosimetry control room there with obviously more modern equipment than ChNPP).
