NorthStar was selected to D&D the University of Illinois’ 1950’s era Mark II
Training, Research, Isotopes, General Atomics (TRIGA) reactor and nuclear
reactor laboratory. 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.

In March 2011, NorthStar was contracted by the University of Arizona to
decontaminate and decommission (D&D) the University’s Training, Research,
Isotopes, General Atomics (TRIGA) reactor and in its nuclear reactor laboratory.
NorthStar dismantled the reactor and its ancillary support systems, removing
all radioactive materials from the NRL, and reducing the radioactivity to levels
that permitted release of the licensed area for unrestricted use and License
termination. Activities were completed in accordance with 10 CFR 20.
Many of the reactor components and systems were either activated or
contaminated and were segregated from non-radiological components, so that
they could be disposed of as low level radioactive waste (LLRW). NorthStar’s
waste minimization emphasis resulted in a reduction to the overall volume of
waste. Highlights of the project included:
• D&D of unique reactor systems and configurations.
• Packaging of radiological contaminated debris for disposal at off-site
licensed facilities.
• Final Status Survey activities to support unrestricted release of the
University’s Nuclear Reactor Laboratory.

December 2014
The dismantlement of Consolidated Edison’s five-block steam and electricity
power plant in midtown Manhattan was phased over a five-year period,
tackling numerous challenges related to a densely urban and compact
construction site.
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 under 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

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.

Florida. There was no dropping of material allowed due to an operating turbine
within close proximity. All steel was lowered to the ground by crane. The scope
required the boiler and support equipment to be dismantled in 3 phases.
Phase I – Dismantle the Boiler without disturbing the main structure. This
phase was conducted by using pneumatic winches (Air Tugers) to lower the
steam piping, water wall frame and water walls. After the water walls were
lowered to the ground, the boiler roof and floor were opened and a 300-ton
crawler crane completed the boiler dismantlement.
Phase 2 – Dismantle the Coal Hoppers from the roof of the Turbine Building
while it was still operating. Working over the 150’ tall boiler structure, the 300ton crane was used to lift out sections of the Coal Hoppers allowing for
dismantlement of the steam drum remaining boiler support structure.
Phase 3 – Using the 300-ton crawler crane, remove the Steam Drum and upper
50’ of the boiler structure.
Multiple Critical lifts required around operating Turbine.
