1.) The "Band of Stability" refers to the
a.) neutron vs electron plot indicating the location of stable nuclei
b.) electron vs. proton plot indicating the location of stable nuclei
c.) proton vs neutron plot indicating the location of stable nuclei
d.) electron vs proton + neutrons plot indicating the location of stable nuclei
True / False ?? a-e

b.) U-235 is fissionable
c.) Naturally occurring uranium is composed of approimately 99% of the non-fissionable istope
d.) water is used to control a fission reaction through neutron moderation
e.) neutron absorption is accomplished through control rods.

possible a.) the US enriches uranium using the 'gas centrifuge method'
"No gas centrifuge commercial production plants are currently operating in the United States. However, both Louisiana Energy Services (LES) and USEC Inc. have recently received licenses to construct and operate commercial enrichment facilities. USEC Inc. was granted a license in February 2004 for a demonstration and test gas centrifuge plant, which is currently under construction. Both of these commercial facilities are now under construction. In addition, on December 30, 2008, AREVA Enrichment Services, LLC (a subsidiary of AREVA NC, Inc.), submitted an application to the NRC, seeking a license to construct and operate a gas centrifuge facility in Bonneville County, Idaho. This proposed plant is known as the Eagle Rock Enrichment Facility. "
true b.) U-235 is fissionable
"is because U235 is "fissionable," meaning that it starts a nuclear reaction and keeps it going. "
true c.) Naturally occurring uranium is composed of approimately 99% of the non-fissionable istope
"When uranium is mined, it consists of about 99.3% uranium-238 or U-238"
false d.) water is used to control a fission reaction through neutron moderation
it is a coolant, not a neutron absorbant.
"The reactor's core contains fuel assemblies that are cooled by water circulated using electrically powered pumps" http://www.nrc.gov/reactors/pwrs.html
true e.) neutron absorption is accomplished through control rods.
"A rod, plate, or tube containing a material such as hafnium, boron, etc., used to control the power of a nuclear reactor. By absorbing neutrons, a control rod prevents the neutrons from causing further fissions" http://www.nrc.gov/reading-rm/basic-ref/…
