What is the main risk during the temporary storage of high-level nuclear waste? A.High-level nuclear waste is prone to undergo fission and create a nuclear explosion when left on its own for extended periods of time. Therefore, high-level nuclear waste must be monitored and maintained with control rods. B.High-level nuclear waste rapidly breaks down into toxic and corrosive chemicals once it is out of the nuclear reactor. The storage facility must be prepared to handle corrosive chemicals for long periods of time. C.High-level nuclear waste generates a lot of heat for 40-50 years. The storage facility must have cooling systems to prevent this heat from building up, damaging the container, and posing a danger to people and the environment. D.High-level nuclear waste requires specialized equipment to transport. Very few vehicles that can transport nuclear waste exist, and improper transportation vehicles will leak radiation to the environment.

Write out the nuclear equations for the following reaction descriptions (fill in missing isotopes). a. Radon-222 decays, forming an alpha particle and b. undergoes an electron capture to form sulfur-32. decays, forming a beta particle and rubidium-86. c.

10.The most researched type of fusion reactor is a design called tokamak. What is the main problem with these reactors? A.the necessary fuel to maintain the reaction B.keeping the plasma contained for long periods of time C.storing the radioactive waste and products safely D.harvesting the small amount of energy released efficiently

Potassium (Z = 19) has three primary isotopes: K-39, K-40, and K-41 a. Determine the most likely type of nuclear decay that K-40 undergoes and write the balanced nuclear equation for one of these decays. b. Potassium-argon (K-Ar) dating is commonly used to determine the age of a sample by measuring the amount of Ar-40 present which was produced by the radioactive decay of K-40. Write the balanced nuclear reaction to show how K-40 becomes Ar-40.
