of contaminated surface) to leak to the surface of the pulp radioactive activity of about 0.3 Ci. Radioactive trace was localised, contaminated soil removed. 27 December 1993 – Incident at radioisotope plant where the replacement of a filter resulted in the release into the atmosphere of radioactive aerosols. Emissions were on the α-activity of 0.033 Ci, and β-activity of 0.36 mCi. 4 February 1994 – Recorded increased release of radioactive aerosols: the β-activity of 2-day levels of Cs-137 subsistence levels, the total activity of 7.15 mCi. 30 March 1994 – Recorded excess daily release of Cs-137 in 3, β-activity – 1,7, α-activity – by 1.9 times. In May 1994 the ventilation system of the building of the plant spewed activity 10.4 mCi β-aerosols. Emission of Cs-137 was 83% of the control level. 7 July 1994 – The control plant detected a radioactive spot area of several square decimetres. Exposure dose was 500 millirems per second. The spot was formed by leaking sewage. 31 August 1994 – Registered an increased release of radionuclides to the atmospheric pipe building reprocessing plant (238.8 mCi, with the share of Cs-137 was 4.36% of the annual emission limit of this radionuclide). The reason for the release of radionuclides was depressurisation of VVER-440 fuel elements during the operation segments idle all SFA (spent fuel assemblies) as a result of an uncontrollable arc. 24 March 1995 – Recorded excess of 19% of normal loading apparatus plutonium, which can be regarded as a dangerous nuclear incident. 15 September 1995 – High-level liquid radioactive waste (LRW) was found in flow of cooling water. Operation of a furnace into the regulatory regime has been discontinued. 21 December 1995 – Cutting of a thermometric channel exposed four workers (1.69, 0.59, 0.45, 0.34 rem) when operators violated process procedures. 24 July 1995 – Cs-137 aerosols released, the value of which amounted to 0.27% of the annual value of MPE for the enterprise. 14 September 1995 – Replacement covers and lubrication step manipulators registered a sharp increase in airborne α-nuclides. 22 October 1996 – Depressurisation occurred in a coil while channeling cooling water from one storage tanks of high-level waste. The result was contaminated pipe cooling system repositories. As a result of this incident, 10 people were exposed to radiation dose of 2.23 to 48 milli-Sieverts. 20 November 1996 – A chemical-metallurgical plant in the works on the electrical exhaust fan caused aerosol
