Ukraine Energoatom – Ukraine

“The YT-800 significantly reduces radiation risk by removing 99% of aerosols during reactor tank cleaning.”
β€” Nuclear Operations Lead, Energoatom

Energoatom is Ukraine’s state-owned nuclear energy operator, managing several active reactor sites. These facilities rely on underwater cooling and storage pools that must be regularly cleaned of sediment, biofilm, and radioactive particles. Safety is paramount, and manual cleaning is restricted due to radiation exposure. Energoatom uses remotely operated robotic cleaning units to maintain these critical assets, minimizing human entry and ensuring compliance with international nuclear safety standards. The approach is central to the company’s mission to operate safely under both normal and contingency scenarios.

The Challenge

When draining reactor tanks, radioactive aerosols are released, forcing a 24–48 hour ventilation period before staff can re-enter. This delayed schedules and increased operational costs.

The Weda Solution


Β Energoatom integrated the YT-800, specially configured for nuclear applications, to clean the floor and walls prior to tank drainage β€” drastically reducing aerosol presence.
