MARSEILLES, Ill. — As a contractor, Jim Orr will never forget his first time at La Salle Station in December 1973.

Although he recalls the long, brisk walk from the parking lot to the plant, what stands out in his mind are the security barriers and safety measures set in place before he entered the nuclear facility.

“It was intimidating to say the least!” Orr recalls with a smile. “Although security in 1973 wasn’t what it is today, it was a completely eye-opening experience to step into the nuclear world.”
