Northwest Demolition was contracted for the demolition of site improvements within the controlled area of the Humboldt Bay Nuclear Power Plant. The site’s reactor containment was sub-grade, with the lowest levels stretching some 90 feet below the ground surface. Project scope involved the demolition of a variety of support structures, as well as the refueling building, spent fuel pool, and the complete removal of the buried caisson structure. The caisson demolition involved sub-grade multi-story demolition and material removal from within the confines of an installed slurry wall.

Northwest Demolition was originally brought on-board for consulting services, but was later contracted to perform the complex demolition operations. This project showcases Northwest Demolition’s consulting expertise, as well as our ability to successfilly transition from strategic planning to operational production.
