1 OurMission Tolicenseandregulatethe nationscivilianuseof byproduct,source,and specialnuclearmaterialsto ensureadequateprotection ofpublichealthandsafety, promotethecommon defenseandsecurity,and protecttheenvironment.

2 TheNRCRegulates

• Nuclearreactors commercialpowerreactors,researchand testreactors,newreactordesigns

• Nuclearmaterials nuclearreactorfuel,radioactivematerials formedical,industrial,andacademicuse

• Nuclearwaste - transportation,storageanddisposalof nuclearmaterialandwaste,decommissioningofnuclear facilities

• Nuclearsecurity - physicalsecurityofnuclearfacilitiesand materialsfromsabotageorattacks 3

WhatWeDont Do

• Regulatenuclearweapons,militaryreactors, orspacevehiclereactors

• Ownoroperatenuclearpowerplants

• Regulatesomeradioactivematerials,suchas Xraysandnaturallyoccurringradon 4

SomeNuclearFacts 99nuclearpowerplantssupply about20percentoftheelectricityin theU.S.

Nuclearmaterialsareusedin medicinefordiagnosisandcancer treatment.

Nuclearmaterialsarewidelyusedin industry,suchasindensitygauges, flowmeasurementdevices, radiographydevices,andirradiators.
