Westinghouse decontamination and segmentation boxes are used to segment and decontaminate equipment, parts and other material that arise during operation and decommissioning of nuclear power plants or other nuclear facilities. The boxes are designed and developed to meet our customers’ specific needs regarding the capacity, plant layout, functional requirements, logistics, dose rate of material and degree of automation by focusing on as-low-as-reasonably-achievable principles. Based on Westinghouse’s broad experience in decontamination and segmentation, each box is equipped with state-of-the-art technology to fully address the needs of the customer. Several segmentation or decontamination technologies can be used inside the box to fulfill complex segmentation and decontamination tasks in a controlled environment.
Example of decontamination box internal equipment
Each decontamination and segmentation box is designed and constructed according to the required available space and the anticipated operation. No matter the size of the structure, steel parts can be assembled inside the dedicated location, and the interior walls box are welded, ground and polished. Furthermore, each box is equipped with a high-efficiency particulate air (HEPA) filter system that keeps a sub-atmospheric pressure inside the box and a directed airflow, even when the doors are open. Boxes can be modular or mobile, and used stand-alone or combined to form a series of boxes as an integrated part of a fully equipped decontamination and waste treatment process.
Depending on the desired application, a customized Westinghouse decontamination and segmentation box can be designed with:
Example of a multi-function box (e.g., segmentation, workshop, decontamination) with foldable roof opening
The advantages of having a customized Westinghouse decontamination and segmentation box include:
Westinghouse has successfully implemented decontamination and segmentation boxes in several German nuclear power plants and in a German research center, some of which have included a decontamination material recycling and treatment system.
