Nuclear Power Infrastructure
High-specification secondary cooling loop descaling and surface prep.
High-specification secondary cooling loop descaling and surface prep.
Nuclear Power Generation Facilities
Secondary cooling loop descaling, forebay dredging, and ALARA-compliant surface preparation.
Nuclear generating stations demand uncompromising technical precision, rigorous radiological safety compliance, and flawless execution during planned outage critical-path windows.
Chow Marine provides specialized secondary-side decontamination, deep water intake clearing, and emergency response services designed in accordance with ALARA (As Low As Reasonably Achievable) radiation protection principles and nuclear quality assurance standards.
Our technicians undergo comprehensive background screening, nuclear security clearance, and specialized radiation protection training. We operate clean, closed-loop UHP systems that prevent cross-contamination in auxiliary buildings, heat exchanger bays, and turbine halls.
In offshore cooling water intakes on the Great Lakes, our teams perform remote ROV and diver-supported thermal water jetting to clear cooling channels of invasive biofouling without introducing foreign materials that could disrupt condenser vacuum efficiency.
ALARA Planning & Pre-Brief
Pre-job dose estimation, micro-containment engineering, radiological zoning, and tool mock-up validation.
Secondary Loop Isolation
Installation of certified radiological barriers, HEPA air handling, and HEPA-filtered vacuum extraction lines.
Precision Decontamination
Low-volume, ultra-high pressure water jetting to eliminate fixed oxide layers and heavy scale with minimal secondary waste generation.
Health Physics Survey
Swipe testing, gamma spectroscopy confirmation, and release certification in full compliance with CNSC guidelines.
