A nuclear decommissioning project achieved a significant reduction in waste classification and disposal costs by deploying Epcon’s custom, sealed batch thermal treatment system. The system is engineered for fully contained operation, utilizing integrated Direct-Fired Thermal Oxidation (DFTO) and robust safety controls to provide safe thermal decontamination and guaranteed compliance under the most stringent regulatory oversight.
Nuclear Decommissioning – Sealed Thermal Treatment System with Integrated Emissions Control
Executive Summary
Project Overview
A nuclear decommissioning effort required thermal treatment of contaminated equipment and components to remove hazardous residues and reduce waste classification prior to final disposal. The process was safety-critical, demanding a sealed environment to prevent the uncontrolled release of contaminants and a reliable system to treat all off-gases generated during heating under strict regulatory scrutiny.
Epcon engineered a containment-focused system designed for safe thermal treatment, auditable control logic, and high reliability in a high-risk environment.

The Challenge
Decommissioning environments require extreme attention to containment, emissions control, and auditable documentation. The customer faced several critical issues:
- Controlled Containment: Need for a fully sealed chamber to prevent the uncontrolled release of contaminated vapors and particulates during thermal processing.
- Emissions Handling: Requirement for a reliable method to capture and completely destroy hazardous off-gases generated when heating contaminated equipment.
- Regulatory Oversight: Demand for a system with redundant safety instrumentation, interlocks, and auditable control logic to satisfy strict oversight and documentation requirements.
- Disposal Cost: High disposal costs associated with contaminated waste that could be reduced by lowering the contamination level via thermal treatment.
The Solution
Epcon engineered a sealed batch oven with integrated DFTO emissions control. The system’s design addresses containment and compliance simultaneously.
Sealed Thermal Treatment Chamber
Sealed Thermal Treatment Chamber
- The oven features a fully sealed construction to contain all vapors and particulates during the thermal process.
- The chamber’s design protects the integrity of the containment boundary throughout the controlled thermal decontamination cycle.
- Off-gases are routed directly from the sealed oven into the DFTO for controlled, high-temperature destruction of all hazardous pollutants.
- This ensures only clean, compliant exhaust is discharged.
- Utilizes automated safety interlocks and PLC-based monitoring for stable, repeatable operation.
- The control logic provides a fully auditable record of the thermal process and emissions control performance.
