What is the radioactive liquid waste drain tank

Release time:

2025-06-06

Radioactive liquid waste drain tank is an important equipment in nuclear facilities for collecting and temporarily storing radioactive liquid waste. Its design and management need to follow strict safety regulations:

Core functions
• Collect radioactive liquid waste (such as cooling water and decontamination wastewater) generated from nuclear reactors, laboratories, etc.
• Provide radiation shielding to prevent the leakage of radioactive substances.
• Be equipped with a liquid - level monitoring and alarm system to ensure controllable capacity.

Design essentials
• Material: Adopt a multi - layer shielding structure of stainless steel + lead lining/concrete.
• Anti - corrosion: Special coating on the inner wall for anti - corrosion treatment.
• Redundancy design: Double - wall structure + leakage detection system.
• Seismic resistance level: Meet the seismic standards of nuclear facilities (e.g., IAEA NS - G - 1.6).

Safety regulations
• Implement the "Nuclear Safety Law" and the "Regulations on the Safety Management of Radioactive Waste".
• Conduct regular pressure tests and radiation monitoring.
• Be equipped with emergency standby storage capacity (usually ≥30% of the designed capacity).

Operation and maintenance requirements
• Implement real - time monitoring of the concentration of radioactive nuclides.
• Transfer the liquid waste through a sealed pipeline system.
• Staff must wear personal dosimeters and follow the ALARA principle.

Note: The specific technical parameters need to be determined according to the nuclear facility license documents.
