Over the many years of my travels to Ukraine and my work at the United Nations I have collect copies of various KGB documents relating to Chernobyl. This is a secret KGB document drafted in 21 FEB 1979 being sent to the Central Committee of the Communist Party of the Soviet Union from Yu. Andropov, Chairman of the Committee
The topic of this letter:
Regarding shortcomings in the construction of the Chernobyl NPP
Secret CC CPSU [Central Committee of the Communist Party of the Soviet Union] Date: 21 FEB 79 05363 Subject to return to the General Department of the CC CPSU
[Header] COMMITTEE FOR STATE SECURITY OF THE USSR February 21, 1979. No. 346-A Moscow
[Addressee] To the CC CPSU
[Subject] Regarding shortcomings in the construction of the Chernobyl NPP
According to data available to the KGB of the USSR, deviations from design specifications and violations of construction and installation protocols are occurring at distinct sectors of the construction of the second unit of the Chernobyl Nuclear Power Plant. These deviations risk causing structural failures and personnel injuries.
The machine hall structural frame columns have been installed with deviations from the reference axes of up to 100 mm; horizontal bracing between columns is missing in specific locations. Wall panels are installed with deviations from the axes of up to 150 mm. The layout of the roof slabs was executed in violation of designer supervision directives. Crane tracks and braking platforms exhibit elevation disparities of up to 100 mm and are inclined up to 8 degrees in certain places.
The Deputy Head of the Construction Directorate, Comrade V.T. Gora, issued a directive to proceed with foundation backfilling in a sector where the vertical waterproofing is compromised in multiple locations. Similar violations, acknowledged by Comrade V.T. Gora and the Head of the Construction Complex, Comrade Yu.L. Matveev, were permitted in other construction sectors. Waterproofing degradation introduces the risk of groundwater infiltrating the station premises, leading to potential radioactive contamination of the surrounding environment.

The Directorate leadership is failing to allocate sufficient attention to the foundational support facilities, which dictate overall construction quality. The concrete plant operates erratically, yielding substandard product quality. Interruptions were permitted during the pouring of ultra-heavy concrete, resulting in the formation of voids and foundation delamination. The access infrastructure for the Chernobyl Nuclear Power Plant is in a critical state of disrepair.
Construction of the third high-voltage line is delayed. This delay constrains the operational power output limits for the second power unit.
Due to inadequate enforcement of occupational safety protocols, 170 personnel sustained workplace injuries during the first three quarters of 1978, resulting in 3,366 man-days of lost productivity.
The KGB of Ukraine has briefed the CC CPU [Central Committee of the Communist Party of Ukraine] regarding the substance of the identified violations.
