AP1000 CVS Stairwell Door

Application: Vogtle Units 3 & 4

The CVS Stairwell Door is a Health Physics Engineered Barrier designed to secure access points within the Chemical and Volume Control System (CVS) stairwell at the AP1000 facility. This system provides a robust, lockable solution for access control while maintaining compliance with radiological boundary management requirements.

Key Features

• Tool-Free Installation: Utilizes threaded jacking feet to anchor to existing stairwell structure—no welding required

• Access Control: Enhances physical security of stairwell entry points

• Health Physics Integration: Supports ALARA objectives by reinforcing radiological boundaries

Installation Considerations

• Wall Clearance: Installation may require relocation of nearby wall-mounted light fixtures

• Non-Invasive: Minimal impact to existing infrastructure

Specifications

• Frame: Heavy-duty steel construction

• Panel: Welded mesh gate for visibility and containment

• Mounting: Four-point jacking system for secure placement

This barrier is engineered to provide fast deployment, durability, and effective control over stairwell access in nuclear facility environments.
