Project Scope:

• Provide a temporary ventilation system to support this critical-path torus re-coat project.
• Design to support grit blasting, application of the new coating system, and accelerated curing to ensure critical-path performance.
• Design, fabricate/procure system components, supervise installation, and provide ongoing engineering support for the coating operations.

Description:

• Maintained a sufficient air-exchange rate within the torus to minimize the airborne DAC levels.
• Maintained the torus volume at a lower negative pressure relative to the torus room and the floors above.
• Generated a sufficient capture velocity across the manway access to minimize the migration of contamination across that boundary.
• Controlled temperature and humidity to support the coating application and minimize the cure time.
• All system objectives were achieved for this critical-path project with no malfunctions or time lost.
