The initiatives to mitigate environmental impacts in midterm are reflected in the Integrated Plan of the ROSATOM’s Environmental Policy Implementation in 2012 and until 2015 (hereinafter referred to as the Plan). According to the Methodological Recommendations for Implementation of the ROSATOM’s Environmental Policy, the Plan is annually updated and contains organisational and engineering nature aimed at reducing negative impacts of the environment.

Results of 2013
JSC Rosenergoatom Concern:
- at Balakovo NPP, the traditional lighting sources of the plant area and premises were replaced with new generation lighting sources based on light-emitting diodes, and a heavy oil-contaminated drain pumping system was upgraded;
- at Smolensk NPP, the scheduled preventive maintenance of the water treatment equipment was carried out along with that of service storm and storm sewage systems; the water chemistry system was upgraded;
- at Kalinin NPP, a filter for the clean-up of dielectric fluids was installed to reduce the amount of generated draining of turbine oil. The fish protection system Pirs and sonar system Peskarik were installed in the pilot commercial operation at the plant’s water intakes.
FSUE PA Mayak:
- during tests of the membrane sorption technology of LRW clean-up at the radioisotope plant, radionuclide clean-up factors of 105 were achieved;
- tests of the new system of local gas clean-up of caesium-137 were continued at the radiochemical plant; the system is based on ceramic cartridges with high-temperature heating. Implementation of this system will allow for local trapping of caesium-137 and reduce its atmospheric release by two orders.
FSUE Aleksandrov NITI:
- the local system for extra drain water clean-up from petrochemicals of 0.3 m3/h capacity was modernised;
- the pilot operation of the pilot system to test its capability to clean-up from petrochemicals to achieve the permissible content of 0.03 mg/l was started;
- the operation of the modular membrane sorption system for LRW conditioning was resumed after a prolonged outage; the system is capable of minimising the radioactive waste volume and reprocessing 30 m3 of LRW to the level permitting its discharge into the natural environment.
- the work was carried out to replace low-efficiency electric ash traps at Boilers Nos. 2 and 6 with high-efficiency wet ash traps; this reduced ash discharges to 6,221 t from 7,743 t in 2012.
- the coal-fired boiler house of the in-situ leaching section was refurbished with the replacement of the critical equipment (boilers, fume exhausts, cyclones) with more advanced ones and the replacement of the gas clean-up equipment with the one having higher efficiency in terms of exhaust gas clean-up; this reduced pollutant releases into the atmosphere. In 2013, the total release of solid substances into the atmosphere during operation of the coal-fired boiler house amounted to 23.807 t, down 4.366 t from 2012 (28.173 t). In 2013, the total amount of liquid and gaseous releases amounted to 74.348 t, down 10.948 t from 2012 (85.296 t).
