Below are sample questions representative of the exercises included on this worksheet and related 12.133 Nuclear Reactions, Fission, and Fusion skill assessments:

Problem 1Difficulty: Mastery

Which integrated comparison is correct for a fission reactor and the Sun?

ABoth use oxygen-supported chemical combustion as the main energy source.

BBoth use uncontrolled uranium fusion in their outer layers.

CA reactor uses stellar fusion, while the Sun uses U-235 fission fragments.

DA reactor uses a controlled neutron-induced fission chain, while the Sun uses gravitationally confined fusion in its core.

Solution & Explanation:Commercial fission reactors use controlled neutron-induced fission chains. The Sun is powered mainly by core fusion under gravitational confinement.

Problem 2Difficulty: Mastery

Use the accompanying fusion triple-product graph. Which trajectory moves a plasma most directly toward ignition conditions?

AThe path that lowers temperature and lowers confinement at the same time.

BThe path that increases oxygen concentration while removing all plasma.

CThe path that increases temperature and the density-confinement product toward the threshold region.

DThe path that changes only the graph color and no physical variable.

Solution & Explanation:Fusion ignition requires sufficient temperature and density-confinement product. A trajectory toward higher values on both axes moves toward the threshold.

Problem 3Difficulty: Mastery

How do delayed neutrons affect the meaning of a reactor's effective multiplication factor in practical control?

AThey are ignored because only electrons can change reactor power.

BThey contribute to the total neutron population and make near-critical control possible over longer response times.

CThey make k meaningless because no neutrons are produced in fission.

DThey cause fusion to replace fission in every thermal reactor.

Solution & Explanation:Effective multiplication includes neutrons that can cause later fissions. Delayed neutrons are few but crucial for controllable changes near criticality.
