Radiation situation dynamics at the Andreeva Bay site for temporary storage of spent nuclear fuel and radioactive waste over the period 2002 –2016

The Coastal Technical Base (CTB) №569 at Andreeva Bay was established in the early 1960s and
intended for the refueling of nuclear submarine reactors and temporary storage of spent nuclear fuel
(SNF) and radioactive waste (RW). In 2001, the base was transferred to the Russian Ministry for
Atomic Energy and the site remediation began. The paper describes in detail the radiation situation
change at the technical site in Andreeva Bay from 2002 –2016, the period of preparation for the most
critical phase of remedial work: removal of spent fuel assemblies. The analysis of aggregated
indicators and data mining were used. The article suggests the best number and location of
checkpoints needed to ensure sufficient accuracy of the radiation situation description. The fractal
properties of the radiation field are studied using the Hurst index. The relationship between
checkpoints was assessed using the method of searching for checkpoint communities. The decrease in
the integral of the ambi...
