You've entered the futuristic city of Neutropolis, where everyday life is just like today, except that advanced technologies have improved transportation, environmental quality, building structures, and overall quality of life. This is America in the Space Age, but you'll quickly discover that the technologies you'll learn about here are already in use and may even be a part of your daily life right now.
You'll also get acquainted with our friends, The Power Pack. Along with Proton, our friendly Nuclear Energy guide, The Power Pack students represent the diversity of a smart, successful society that embraces and uses clean, safe nuclear energy.

The lovable greeter, Proton, is a nurturing guide for both you and his young human companions. He’s friendly, helpful, and kind. Small but strong, he will lead you on your journey for knowledge about nuclear energy, its uses, challenges, and future outlook.
Electra On
Electra is a fashion-forward teenager who is concerned about sustainability and a clean environment. Her favorite subject is science, and she plans to study nuclear engineering after she finishes high school. She is far from “nerdy,” however, as her clothes and hairstyles are always on the cutting edge of cool. She is the eldest of the Power Pack.
Newt R. On
Electra’s younger brother Newt is a scooter-riding, fun-loving middle-schooler. He’s into space sports, toy rockets, and history. He spends a lot of time playing games with Proton, often asking historical and scientific questions that he hopes might stump his flying friend. He shows definite signs that he'll grow up to become a teacher.
Enrico Rey
A neighbor of the On family, Enrico is named after the famous scientist Enrico Fermi, a fact he hopes will help bring him fame of his own someday. Soon to learn to drive, his dream is to be a space explorer. Halfway in age between Electra and Newt, Enrico is easy friends with both of them. While he joins Newt in sometimes wild and reckless antics, Enrico tends to be the problem-solver of the group.
Ura Nehum
The youngest of The Power Pack, Ura is perhaps the smartest of them all. At eight, she already knows she wants to be a doctor. Somewhat of a “tomboy,” she can sometimes beat Newt in certain space sports, but she also loves to go shopping and hang out with Electra whenever the elder girl babysits her. Though always ready for fun, Ura is also concerned with safety and helping the group to make healthy choices.
