Influence of the Lira Facilities on The Radiation Conditions of the Adjacent Territories: Results of the Four-Year Monitoring
The Lira facilities are six underground cavities with the volume of each is 50000 cubic meters, it were made at the depth of 800 - 900 meters with use of underground nuclear explosions. They were made in 1983-1984 and located in the northern part of Contractor site Karachaganak oil and gas condensate filed (KOGCF). In compliance with adopted classification of nuclear explosions all carried out explosions are correspond to category of Total Camouflet Explosions i.e. accident – free and without essential ejections of radioactive substances. The cavities TK-1, TK-2, TK-3, TK-4 and TK-6 during completion after explosions were dry and suitable for further construction and cavity TK-5 was filled by water. Now the cavity TK-1 and TK-4 are technological developed, partially filled by condensate and they are under pressure about 40-atmosphere pressure. The works on cavity TK-6 construction did not complete because of breakage. To control cavity TK – 5 condition the control – observation wells regime was made.
