which of the following statements is correct regarding spent fuel rods?

they are no longer radioactive.

they contain only one type of isotope of the fuel (uranium).

they usually remain radioactive for less than 100 years.

they are scheduled for deep underground burial.

During a nuclear reaction, fuel rods generate a tremendous amount of heat. ... Problems cooling these pools have officials worried that the spent rods could ... appear to be related to one or more of the spent fuel storage pools at the plant. ... These fission byproducts are also very radioactive.

does that kind of help a little?

They are scheduled for deep underground burial

Explanation:

Honestly none of these answers are correct in a sense.

They are no longer radioactive - This one is absolutely false since spent fuel rods remain dangerously radioactive for about for about 10,000 years

They contain only one type of isotope of the fuel (uranium) - There will be some 235 isotopes as well as some 238. Other isotopes might be present as well but only in very small amounts.

They usually remain radioactive for less than 100 years - As mentioned above, spent fuel rods remain dangerously radioactive for about 10,000 years.

They are scheduled for deep underground burial - This answer is probably the best as it it somewhat true. In the 1980's there was a plan launched by the federal government to bury spent fuel below Yucca Mountain in Nevada. However, this project was later called off to think of a better means of containment.

However...

Scandinavia and Finland have already approved an approach known as "deep storage" and have already begun to work on their own sites.

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
