Nuclear Industry: Radioactive Material Handling (Containment & Protection) Cleanroom Solutions

I. Application Scenarios & Solutions

1. Radioactive Material Storage & Processing

   • Negative Pressure Modular Cleanrooms:

     • Maintain ISO Class 4-5 air quality with HEPA/ULPA filtration (99.999% efficiency for ≥0.3μm particles).

     • Leak-tight welded structures with lead-lined walls for radiation shielding.

   • Biosafety Pass Boxes with Airlocks:

     • Enable safe transfer of radioactive samples using dual-door interlock systems and integrated decay chambers.

2. Waste Treatment Zones

   • Robotic Handling Cleanrooms:

     • FFU-supported laminar airflow to suppress airborne particulates during vitrification or compaction of nuclear waste.

   • Decontamination Air Showers:

     • High-pressure HEPA-filtered airflow to remove radioactive dust from personnel and equipment exiting hot zones.

3. Fuel Rod Fabrication

   • Inert Gas Cleanrooms:

     • Modular cleanrooms filled with argon/nitrogen to prevent oxidation, coupled with FFUs for particulate control during cladding.

4. Emergency Response & Maintenance

   • Mobile Containment Units:

     • Rapid-deploy modular cleanrooms with integrated air filtration for on-site repairs in contaminated areas.

II. Core Technologies & Compliance

• Radiation-Resistant Materials:
  Stainless steel cleanrooms with lead/borated polyethylene shielding (up to 5 Sv/h attenuation).

• Multi-Stage Filtration:
  Pre-filters + HEPA + activated carbon filters to capture radioactive iodine and particulates.

• Real-Time Monitoring:
  Integrated radiation sensors, pressure differential alarms, and particulate counters linked to SCADA systems.

• Certifications:
  Meet IAEA GS-R-3, ISO 17873 (nuclear facility ventilation), and 10 CFR Part 20 standards.
