While other teenagers might be busy taking care of their personal pages online or playing games for hours，14-year-old Jackson Oswalt from Memphis has been busy doing something different.He has spent his free time building his own nuclear reactor （核反應(yīng)堆） in his home.Now，the boy is praised by city leaders for his achievement as he is the youngest person to have achieved nuclear fusion （核聚變）.
At just 12 years old，Jackson chose to spend his time exploring his interest in nuclear physics.After scouring the Internet，the student learned of the story of Taylor Wilson，an Arkansas boy who won recognition in the field of science as the youngest person to achieve nuclear fusion in 2008 at the age of 14.Jackson was greatly inspired by him.
The process of the nuclear experiment is not easy at all.But Jackson thought if Wilson could do it，then he could，too.Maybe he could even break Wilson's record in the process.The boy started his project by turning his playroom into a laboratory.Then he bought different kinds of things to build own nuclear fusion reactor.
"The beginning of the scientific research was just learning about what other people had done with their fusion reactors，" Jackson said.His parents spent nearly ＄8，000 to ＄10，000 supporting his nuclear experiment. "With the money，I searched for and bought the parts that I needed.Often the parts I found were not exactly what I wanted，so I had to make improvements to them."
Jackson's hard work finally paid off.Hours before his 13th birthday，he made history as the youngest person to achieve nuclear fusion in January last year.Months after the project，Jackson continued to test his fusion reactor to further prove his project.On Tuesday，Memphis City leaders officially praised Jackson's achievements with a resolution.
