H Canyon
• Built between 1951 and 1954
And began operating in 1955.
• Recovers uranium from spent
reactor fuels.
• Also has recovered Neptunium
and Plutonium.
• About 1000’ x 120’ x 75’ .
• Two canyons – Hot and warm
each divided into 18 sections.
• No entry permitted into the Hot Canyon due to radiation rates and limited entries into the Warm Canyon.
• All work in canyons performed by overhead cranes.
• Use of nitric acid in processing has degrade concrete in some areas.

Potential Robotics Applications in H Canyon
• Removal of concrete degradation products from canyon cells and sumps and in-cell repair of concrete walls.
• Inspection and repair of canyon structures such as the Canyon Air tunnel or exhaust stack.
• Size reduction of failed canyon equipment to reduce waste volume.
• Transfer of high dose material from shipping drums into fuel tubes.
• Inspect and repair piping in difficult to access locations such as confined spaces.
• Interior inspection of piping.
• Waste drum movements and assay.
• Emergency response to chemical and/or radiological solution spills.

HB Line
• Built in early 1980’s and began
operating in 1955.
• Recovers neptunium and
plutonium from solution.
• Sits atop H Canyon
• Most operations are hands-on
Inside glove boxes with little
potential for application of robotics.

K Area Complex Plutonium Storage
• Originally built as a production reactor, it was refurbished at the
end of the cold war to store excess Pu.
• It also contains one glovebox to examine
Pu storage containers to ensure
continued safe storage.
• Provides plutonium metal feed to HB Line
for conversion to oxide. Plutonium oxide
Is then shipped back to K Area.

Potential Robotics Applications in K Area
• Movement and stacking of drums in the material storage area to improve safety and reduce radiation dose to workers.
• Semi-autonomous inspection and scanning of building structures and components.
• Unpacking high-risk plutonium storage drums.
• Movement of drums of heavy water.

L Area Spent Fuel
SRNS – Savannah River Nuclear Solutions
• Originally built as a production reactor, now only the fuel basin is used to receive and store US origin spent nuclear fuel from both foreign and domestic research reactors.
• Also ships fuel to H Area for dissolution and recovery of uranium.

Potential Robotics Applications in L Area
Cask decontaminationand surveying
• Fuel integrity inspections during storage
• Fuel inspections before opening a transportation package (enter package through vent/drain ports)
• Building inspections similar to K Area including underwater
• Nuclear Material Accountability of dry fuel storage area
• Underwater Cask lid bolt removal
• Inspection of Basin water filtration system
• Emergency response radiological events.
