TEES Nuclear Science Center• 1 MW TRIGA Reactor
– Student, Professional, and Emergency Response Training.– Renewed pursuit of research (especially materials science)
• 4 or 5 Beam ports under redevelopment• Large irradiation venues (thermal column, dry cell, & large pool)• Two small hot cells for hot sample handling and isotope packaging.
– Neutron and high activity gamma irradiation of materials and biomaterials.
– Neutron activation analysis (rabbit tube delivery).– Isotope Production & Shipping.
Operating Since 1961
Basic Facts• 1 MW TRIGA (License R-83)
– Planning/construction began in 1957.– Operating since Dec. 18, 1961 (100 kW)
• Multiple Modifications in first 5 years (1965 to 1969 highlights)– Pool modification (dry cell) & stainless steel liner.– Cooling system installed to enable 1 MW
operation.– Core conversion (TRIGA for 1 MW and $3 pulse).– Construction of the “Laboratory Building”
• Multiple Changes over the Years.– 1973 FLIP TRIGA core transition.
• Refueled with LEU in 2006.– Reactivity insert limit dropped to $1.90– Considering/prepping for power uprate to 1.5MW.
Basic Capabilities• Flux levels for face and in-core positions, pneumatic
sample positions, dry cell and radiography beamport.
• Inactive Potential– Beam ports 1-3 & 5– Thermal column,– In-core dry tube.
