Final answer:
The reader can conclude that most states are storing their spent fuel in casks rather than in pools.
Step-by-step explanation:
After analyzing information from both the article and the bar graph titled "Storage of Commercial Spent Fuel by State Through 2013", the reader can conclude that most states are storing their spent fuel in casks rather than in pools. The article mentions that the waste fuel is being stored in "temporary" pools and is accumulating. Additionally, the graph shows that the number of casks used for storage is higher than the number of pools in most states.
