ON THE OPTIMIZATION OF ENGINEERED SAFETY BARRIERS AT A NEAR‑SURFACE RADIOACTIVE WASTE DISPOSAL FACILITY PROVIDED LOW-LYING GROUNDWATER LEVELS

JOURNAL: 2024, ¹ 3 (28), p. 76-82

AUTHORS: N.A. Anisimov, E.V. Sizonenko

ANNOTATION:

The paper explores the potential for optimizing the designs and materials of protective screens at a near-surface radioactive waste disposal facility (NSDF) provided its base being installed above the groundwater level. It presents the calculation results evidencing that the drainage windows provided in the bottom protective screen (instead of continuous clay retainer) would reduce considerably the radionuclide releases from the NSDF into groundwater. The paper discusses the advantage associated with gravel-sand mixture used instead of clay in the lateral protective screen designs contributing to additional drainage of seepage water from the disposal compartments with radioactive waste packages.

Keywords: radioactive waste, engineered barriers of NSDF, radioactive waste packages, anti-immigration barrier, intensity of radionuclide releases to the ground water level.
