NorthStar dismantled, removed, and packaged the reactor, systems, and structures and decontaminated and removed radiologically contaminated surfaces, components, and debris with unrestricted site release in accordance with 10 CFR 20. This included the removal and packaging of the 60R/hr. rotary specimen rack and other irradiated hardware from the reactor core area into a Type A cask. Built in 1959, the research reactor was placed in “safe storage” mode in 1998, when its 30-year operating license expired. The 1.5 megawatt reactor was used for research, student instruction, and service to the industry. It produced no electricity, but was used in a wide variety of research applications. The NRC terminated the University’s reactor license in January 2013, following NorthStar’s demolition of the facility and FSS. Working within the regulatory framework of the Nuclear Regulatory Commission (NRC) and Environmental Protection Agency (EPA), contaminants were removed inside the facility and included neutron-activated aluminum, steel, concrete, and fission products and laboratory radiological nuclides used in various experiments.

SURGICAL DEMOLITION The five-block Kips Bay, multi-building campus was squeezed between FDR Drive, First Avenue, and the Queens-Midtown Tunnel vents, with the tunnel running un- der the property. NorthStar demolished the 11-story office building and support structures first. The switch house and frequency house both had an arched roof like a gymnasium, so it was carefully removed to reduce the potential for the walls to become unstable. The next phase was the most challenging. Three 300-foot steel stacks, reinforced with gunite, towered over the two 17-story power plants. These structures were dismantled by hand in a very controlled manner until the core machinery was visible. The exterior walls of the power plants rose flush to the sidewalk boundary requiring hand demolition on these exposed walls to protect pedestrians, traffic and contiguous property. High-reach equipment was used on the demolition of the lower level power plants The Safe Decontamination & Decommissioning Experts 18 Key Power Clients 2 Humboldt Bay Power Plant | Eureka, CA Highlights 143-Acre Shuttered Power Plant TRC Customer Solutions Debris Recycling Mechanical Demolition Torch Cutting Demolition Hazardous Material Abatement Zero OSHA Recordables December 2014 PG&E’s Humboldt Bay Power Plant (HBPP) was repowered to more efficiently meet California’s growing power needs. As part of this effort, NorthStar abated and demolished shuttered major components of the plant to make room for new facilities, including a 2.7 million gallon liquid fuel oil tank, 4,200-linear-foot fuel oil pipeline, and series of structures, facilities, and underground utilities. The 143-acre nuclear power plant site was built in the 1950s and operated from 1963-1976 until concerns about newly discovered seismic faults combined with more stringent nuclear requirements following the Three Mile Island accident rendered the small plant unprofitable. In 1988, the nuclear plant went into SAFESTOR status, except for two original fossil-fuel-powered steam-turbine generators, which continued to produce power. The underground utilities posed a unique set of challenges. Record drawings of the subsurface conduit locations and the changes that had taken place over the last 50 years could not be located. As a result, the subsurface demolition had to be meticulously executed. Also, pre-project engineering evaluations and procedures included field “hold points” to identify and verify if utilities were ‘live’ so work crews would be safe and avoid disruption to plant operations.
