Decay Tanks
The decay tanks developed by H2O EQUIPEMENT ensure the safe management of hospital radioactive effluents.
Designed to meet the strictest standards, they allow temporary storage, confinement, and neutralization of discharges from nuclear medicine departments and laboratories.
These solutions provide reliable treatment of nuclear effluents while protecting patients, staff, and the environment.
- Volume from 500 liters to 6000 liters
- Possibility to switch to multiple tanks
- Isolation and sampling
- Tanks fully custom-made according to available space, doors, and corridors for transport
- Complete alarm system with BMS, BAS, and supervision connectivity
- Remote display with the possibility to perform measurements
We provide guidance from the design phase to help identify the technical room and also determine the required volume.
Process with multiple custom-made tanks with diameter and height adapted to the volume
Alarms are centralized in our control panel, which reports to the supervision system or BMS/BAS
Possibility of a maintenance contract for the entire process
Decay Tank Effluent Treatment Station
H2O EQUIPEMENT specializes in designing custom solutions for the treatment of hazardous waters and effluents. We offer radioactive decay tank stations compliant with regulations, intended for hospitals, laboratories, and nuclear medicine departments.
Context and Challenges:
Radioactive effluents mainly come from medical and research activities, including nuclear medicine, brachytherapy, radionuclide injections, and the use of so-called « hot » sinks.
These discharges contain radioactive isotopes with varying half-lives. Before any release into the sewer network, they must be stored in decay tanks so that their radioactivity naturally decreases to a regulatory threshold.
In France, the decree of July 23, 2008 establishes the technical rules governing the management of these effluents. Each concerned facility must therefore be equipped with appropriate and secure devices.
Principle of a decay tank station:
A radioactive decay tank station relies on several essential elements:
- Storage tanks: generally at least two tanks to manage effluents alternately (filling one tank while the other is in decay).
- Adapted capacity: sizing depends on the volumes of effluents generated, their emission frequency, and the nature of the isotopes present.
- Dedicated technical room: sealed, secure, with clear signage and controlled access.
- Advanced security: level probes, visual and audible alarms, retention basin in case of leaks, centralized supervision possibly linked to BMS/BAS.
- Radioactivity control: sampling or continuous monitoring before any release into the public network.
- Differentiated management: possibility to separate short-lived effluents from others to optimize storage t
We bring our experience, our expertise and our know-how to support our customers through all their problems in the water industry.
