What Are Reactor Building Renovations?
Reactor building renovations involve upgrading, restoring, or modifying the physical structures, systems, and safety components within or around the reactor building. These projects can range from concrete repairs to major system replacements.
Common renovation activities include:
-
Structural reinforcement and concrete restoration
-
Steel replacement and corrosion repair
-
Radiation shielding upgrades
-
HVAC and ventilation modernization
-
Pipe and valve replacement in containment areas
-
Electrical and instrumentation upgrades
-
Leak mitigation and containment improvements
-
Safety system modernization
-
Seismic reinforcement and structural retrofits
Every renovation must be executed with strict precision due to the sensitive and regulated nature of reactor environments.
