Safety
• HFIR/REDC– yellow railings, caution signs, fire doors,
PPE, radioactive waste bins, support for power loss, professional training, dosimeter, eye wash, shower, hot cell containment, contamination check
• Safeguards Lab– Safety goggles, safety training,
caution/radiation signs, samples in envelopes
• Graphite Reactor– PPE, training, caution/radiation signs,
railings, portal shielding

Security
• HFIR/REDC– locked doors, cameras, instrument/manual shut down, log book,
dog bone size, HEU, grant of access for foreign nationals
• Safeguards Lab– RFIDs on guns, output/depleted uranium barrels, limited access,
security cameras, portal monitoring
• Graphite Reactor– Top secret facility used for Pu production– Materials produced stored in barn before transported to LANL– Barbed wire for U-233 storage

Material Control and Accounting
• HFIR/REDC– Measurement of small amounts of isotopes– Transport of materials – Mass spectrometry
• Safeguards Laboratory– Helium-3 and plastic scintillator detectors for neutron and gamma
portal monitoring.– Testing of uranium enrichment live accounting.– RFID for material tracking and better efficiency.
• Graphite Reactor– Accounting for irradiated fuel/Pu production

Inspection
• HFIR/REDC– Not regulated by NRC, under DOE– Look for adherence to protocol, did reactor behave properly in
given situation
• Safeguards Lab– Mock set ups, no SQs of material
• Graphite Reactor– NRC/ IAEA did not exist
