NUCLEAR REACTOR SHIELDING
Protective Barriers for Controlled Nuclear Environments by Astra Shield
Nuclear reactors are powerful energy sources, but they generate intense ionizing radiation—including neutrons and gamma rays—that must be precisely controlled to ensure safety and environmental compliance. At Astra Shield, we provide engineered nuclear shielding systems that mitigate radiation exposure, support reactor operation, and maintain regulatory standards.
Our Shielding Expertise Covers:
- Neutron Radiation Shielding
We deploy hydrogen-rich shielding materials—such as borated polyethylene, water tanks, and concrete—to slow down and absorb fast neutrons effectively.
- Gamma Radiation Shielding
For penetrating gamma rays, we design layered barriers using lead, high-density concrete, steel, or tungsten composites, customized for energy levels and space constraints.
Where Our Shielding Is Used:
- Nuclear power plant cores & containment buildings
- Research and test reactors
- Spent fuel storage zones
- Hot cells and radiochemical labs
- Radiation waste processing & transfer stations
- Reactor control rooms & observation galleries
Shielding System Design Highlights:
Custom Simulation & Modeling
We use advanced radiation transport software to simulate dose distribution and optimize material thickness and placement.
Modular or Poured-in-Place Structures
Depending on site logistics, we offer precast panels, poured shielding blocks, or removable/modular enclosures.
Ventilation & Access Protection
Specialized shielded penetrations, labyrinth passages, and shielded HVAC inlets to preserve protection during operational use.
Structural & Thermal Integration
Designs include support framing, thermal resistance, and fire protection layers suitable for reactor operating environments.
Safety & Compliance
Our nuclear shielding solutions conform to stringent international guidelines such as:
- IAEA Safety Standards
- ANSI/ANS Nuclear Facility Design Standards
- NRC (US Nuclear Regulatory Commission) Requirements
- ISO and IEC Radiation Protection Codes
