5 Our Mis s ion
- To licens e and regulate the nations civilian us e of byproduct, s ource, and s pecial nuclear materials to ens ure adequate protection of public health and s afety, promote the common defens e and s ecurity, and protect the environment.
6 Some Nuclear Facts 104 nuclear power plants s upply about 20 percent of the electricity in the U.S.
Nuclear materials are us ed in medicine for diagnos is and cancer treatment.
Nuclear materials are widely us ed in indus try, s uch as in dens ity gauges,
flow meas urement devices,
radiography devices, and irradiators.
7 The NRC Regulates
- Nuclear reactors - commercial power reactors,
res earch and tes t reactors, new reactor des igns
- Nuclear materials - nuclear reactor fuel, radioactive materials for medical, indus trial, and academic us e
- Nuclear was te - trans portation, s torage and dis pos al of nuclear material and was te, decommis s ioning of nuclear facilities
- Nuclear s ecurity - phys ical s ecurity of nuclear facilities and materials from s abotage or attacks
8 What We Dont Do
- Regulate nuclear weapons, military reactors, or s pace vehicle reactors
- Own or operate nuclear power plants
- Regulate s ome radioactive materials,
s uch as naturally occurring radon
9 How We Regulate
- Es tablis h rules and regulations
- Is s ue licens es
- Provide overs ight through ins pection, enforcement, and evaluation of operational experience
- Conduct res earch to provide s upport for regulatory decis ions
- Res pond to events and emergencies
10 As s urance of Plant Safety
- Require defens e-in-depth
- Require long-term maintenance of equipment
- Require continual training of operators
- Verify compliance with regulations
11 What We Do - Nuclear Was te
- The NRC regulates :
- Storage of s pent reactor fuel in fuel pools or dry s torage cas ks
12 What We Do - Nuclear Security
- NRC Requires :
- Well-armed and well-trained s ecurity forces,
- Surveillance and perimeter patrols,
- State-of-the-art s ite acces s equipment and controls,
- Phys ical barriers and detection zones, and
- Intrus ion detection s ys tems and alarm s tations.
13 NRC Performance Goals
- Safety: Ens ure adequate protection of public health and s afety and the environment.
- Security: Ens ure adequate protection in the s ecure us e and management of radioactive materials.
