Acknowledgments
I would like to thank the numerous people who shared their memories and their expertise about the SL-1 incident. Among those most generous with their time were John Byrnes, Robert and Bette Vallario, Stephen Hanauer, Dr. George Voelz, Don Petersen, Egon Lamprecht, Susan M. Stacy, Ed Fedol, and Diane Orr. Special thanks must also go to the graduates of the U.S. Army's Nuclear Power Program, who graciously cast their memories back more than forty years.
Nuclear theory, nuclear engineering and nuclear radiation are complex subjects, and I make no claim of expertise. In an effort to make this book readable—and to keep the focus on the human drama at the SL-1 reactor—I chose to boil these concepts down to the basics. Any errors in fact or context from doing so are entirely mine.
Finally, I would like to acknowledge my two wonderful daughters, Shannon and Caitlin, whose support never wavered during the long gestation of this book.

Prologue

It's hard to say when it all went to hell.
The mug shots of Jack Byrnes and Dick Legg taken at the beginning of their last military assignments betray no hint of the elemental forces that would soon engulf them. Missing from the muddy black-and-white photographs is evidence of the reckless passions and base instincts of two saboteurs—or, conversely, the bewildered innocence of a couple of patsies—that would make them the main players in one of the most mysterious human dramas in industrial history. Sure, if you search their faces for telltale signs of character, you might glimpse something intense and smoldering in the deep-set eyes of Jack Byrnes; you might detect a slight, smug smile on the squarish face of Dick Legg. But that's just mental rubbernecking. It's been more than four decades since the photographs were snapped, and they don't offer up much besides a musty smell and a record of bad haircuts. There's no indication the two weren't destined for long lives and ordinary deaths.
The passage of years and the death and silence of friends and family have left but the bleached bones of the two men's histories. They left no diaries, no record of notable achievements, and few anecdotes to hint at the mix of characteristics that made up their personalities. When they arrived in 1959 in Idaho's fertile Snake River Valley to take up what would be their final posts, Byrnes and Legg were still unformed, still works-in-progress, their individual potentials and futures as fuzzy as their service photographs. They were typical American boys on the cusp of manhood, at that age when character, talent, and limitations are just beginning to emerge. Born in the late 1930s in quiet American towns, the two played soldiers while real ones marched across Europe in World War II. As teens, they saw a great explosion in American power as those soldiers came home and rebuilt their country on the GI Bill, a package of government benefits that allowed soldiers to buy houses and attend college. Byrnes and Legg were young men of their time, schooled in the buoyant hopes of prosperity and order, confident that progress would give them better lives than their fathers, agitated by the sense of change and possibility that was sweeping America at the cusp of the 1960s.
The new god that emerged after World War II—the tripartite deity of industry, science, and technology—promised to make all these things possible, even for those of modest means and education. It was the atomic age, when Americans decided they had the knowledge, right, and wisdom to harness for other uses the terrible power released upon Hiroshima and Nagasaki. The atom had ended the war, smote the enemy. But surely its power could be tamed, used to power boats and planes, deliver unlimited electricity, revolutionize medicine. Atomic energy, America's leaders promised, would checkmate America's enemies while it bestowed on all others the gift of limitless energy. It was a seductive idea—using nondescript uranium ore to transform the world.
By the time Jack Byrnes and Dick Legg peered at the lens of a military camera, they had bought into this atomic-powered version of the American Dream. They were determined young men in a hurry, hungry for the good things in life, cocksure about their abilities and opportunities. For them and thousands of others, there was no better place to find the new America than at the National Reactor Testing Station, located on the vast expanse of sagebrush in Idaho's Lost River Desert. Established in 1949, the classified site lay just west of the Snake River Valley and was a monument to the golden age of nuclear science. It was a place where American men fearlessly played with the atom. When Byrnes and Legg arrived, almost two dozen nuclear reactors dotted the desert floor, prototypes of machines that would revolutionize propulsion and energy—and life. Government-issued films of the time celebrated the “new hope of the atomic era” and hinted at the blessings it would afford. Standing before models of prosperous and gleaming cities, film narrators—invariably white men in crew cuts and black suits—championed the glorious changes nuclear power would introduce to the arts, humanities, and sciences. An article in a 1958 issue of National Geographic concludes that “abundant energy released from the hearts of atoms promises a vastly different and better tomorrow for all mankind.”
There were a few people who had doubts about the message. Ranchers and sheepherders in the American West were starting to voice concern about radioactive fallout from the nuclear weapons testing then being conducted in the Nevada desert, fallout that had made its way north to the Lost River Desert. Some experts and interest groups were raising questions about storing radioactive materials and locating nuclear plants near large cities. There were even some who scoffed at the rosy nuclear future portrayed in publications and documentaries at the time. But generally, the American people—and the folks in Idaho—believed the benefits of atomic energy outweighed the dangers it posed. For Byrnes and Legg, the lure of the atom had little t
o do with the promises and peril it posed to mankind. For them, it meant a paycheck and it meant a brighter personal future. They joined a select group of young engineers, construction workers, soldiers, and scientists flooding the wilds of Idaho to turn nuclear dreams into reality.
Then came January 3, 1961, a day that foreshadowed the dimming of the atomic dream, even if it remains a curiously obscure date to all but a few nuclear insiders. That afternoon, Byrnes arrived at a small experimental army nuclear reactor for his shift with Legg and a trainee, Richard McKinley. The three were scheduled to perform routine maintenance work. Nothing suggested that it would be anything other than an ordinary night.
But just a few short hours later, the ordinary became extraordinary. The events that unfolded in the crude silo of Stationary Low-Power Unit 1 on that January night would spawn more than four decades of scandalous rumors and speculation in the closed world of the nuclear industry. That one cataclysmic night would underscore the fragile line between the fallibility of man and the complexity of an intricate science. It would also reveal, but only much later, how a government shaped by a pervasive Cold War mentality would protect the then-fledging nuclear industry from public scrutiny.
While there were markers on the road leading to the chaos and calamity of that night—men with increasingly tumultuous personal affairs and a reactor with malfunctioning equipment—it was impossible to predict how these elements would collide in such a mysterious, unprecedented manner. Despite a nuclear testing facility that housed highly sensitive, top-secret equipment and some of the brightest minds of that generation, there was no way to measure, test, or imagine what would happen in the frigid southeastern Idaho desert on that January night. There was no way to predict the disaster.
1. Nuclear Apprenticeship
In late October 1959, United States Army soldier Jack Byrnes, twenty years old, set off from his hometown of Utica, New York. A trunk was tied to the roof of his black Oldsmobile; his wife, Arlene, was beside him in the front seat, and his son, Jackie, not yet two, was squeezed in the back among the couple's possessions. They were headed west to Idaho for a new adventure, a more promising future. A reel of eight-millimeter film the couple shot in Yellowstone National Park, not far from their new posting, snared them in celluloid. Jack is handsome and well built, his blond hair just starting to darken. Arlene, blinking at the camera, is thin, pretty, and vivacious. She dotes on young Jackie. Yellowstone is devoid of tourists. Old Faithful erupts on cue.
Born June 22, 1939, in Utica, John Byrnes III was the oldest of four children in a Catholic family. His father was a hard-working real estate salesman. By the early 1950s he was making a pretty good living—good enough to buy a cabin nestled amidst New York State's Finger Lakes. During summer and winter vacations, the elder Byrnes introduced his son—everyone called him Jack—to water sports and snow skiing, expensive pastimes even then. Soon Jack, a naturally athletic kid, was blasting watery arcs offshore from his dad's cabin and carving hairpin turns on the icy slopes of local ski hills. Bright and easily bored, the teenaged Byrnes didn't have a lot of interest in school. He liked girls, he liked driving fast, and he liked going out with his buddies to cruise Utica's hot spots and those in the nearby town of Rome.
“He was just a happy-go-lucky guy,” recalls one acquaintance. “He was one of those daredevils. He'd try anything.” Others, though, say the young Byrnes was more complicated than that, even in his adolescent years. Away from his friends, Jack was a serious, intense young man. He liked to do things his way, and when that didn't happen, his temper could flare.
During his high school years, he met Arlene Casier, who attended Rome Free Academy. Arlene, whose father had died, was living with her mother, a quiet, dignified woman. According to a good friend of theirs, both Arlene and Jack yearned for security and the good things in life, and both were in a hurry to get them. Byrnes, his father said years later, was a kid who wanted to grow up fast. At seventeen, he fudged his birth records and joined the United States Army. By the time he was nineteen, he had married his eighteen-year-old sweetheart and begotten a child.
After Jack's basic army training, Jack and Arlene plunged headfirst into the stressful world of military life, where the pay is low, moves are frequent, and extended family is always too far away. The couple quickly discovered just how little control they had over their new life. Their first posting in Newfoundland, a sea- and wind-battered province on Canada's east coast, could hardly have been more remote. During his stint in Canada, the Byrnes's first and only child, John—called Jackie by family members—was born. While adjusting to fatherhood, the young GI was assigned to mechanical training and spent his first year and a half in the military learning how machinery worked, how to maintain it, and how to fix it.
Sometime in 1958, Byrnes became aware of a new nuclear program run by the army at Fort Belvoir, Virginia, just south of Washington, DC. The army had built a small teaching reactor and was recruiting men from all three branches of the military service to learn the science of coaxing heat and electricity from atoms. The army planned to have the trainees operate a string of small, portable nuclear reactors that would be located in remote areas of the world. It seemed like an exciting prospect to Byrnes, certainly far better than fixing a tired generator at a bleak army base. He applied for the training program and was accepted. One of his classmates was Dick Legg, who had strolled into the nuclear world in much the same way.
* * *
Sailor Dick Legg, twenty-five years old, left for Idaho Falls, then a bucolic town with a population of about thirty thousand nestled on the banks of the Snake River, about the same time as Byrnes. The backseat of his car was filled with archery gear. No one sat in the passenger seat, but finding a girl would be a top priority after he settled in at his new posting. He, too, was excited about his move west. Although relocating to southeastern Idaho meant putting a lot of distance between him and his family in upper Michigan, Legg was an outdoorsman, and the landscape he saw flying past the car window as he drove confirmed that there would still be expanses of forests he could walk through with his bow at the ready.
Dick Legg was born in 1934, the youngest of Louis and Mary Legg's three sons. The family liked to say that the newest member of the family was the last of the three Ds: Don, Doug, and Dick. Louis Legg owned a small timber mill near the Huron National Forest. Legg and his brothers were bused, and later drove themselves, from their hometown of Roscommon, population five hundred, north to the larger town of Grayling to attend school. Legg, who showed no interest in sports, was a B and C student; smart enough, but distinguished mostly by his classroom antics, which earned him a reputation of being a class clown and a prankster. Legg's favorite way to spend his free time was to take off on his own into the wilds of Michigan. What he really liked—long before he had a driver's license—was careening in one of his brothers' cars down country back roads. Before he had reached his teens, Dick had taken up archery, and it became a passion. He often roamed the woods near his home with a bow in hand. Something about the solitude of the sport agreed with him.
As a teenager, Legg worked at his father's mill during summer vacations, helping run a massive blade through the stripped logs. The work put muscles on Dick, a source of pride for a guy who was touchy about his height of five foot six. But even with the muscles, Legg didn't easily attract women; he sported black-framed “geek” glasses, a pouty lower lip, and a large mole near his left nostril. But he did get attention, both wanted and unwanted, with his quick wit, smart-ass comments, and pranks. Legg's cousin remembers him as a jokester with a ready smile and, as the youngest in the family, a kid not weighed down by the expectations attached to his older brothers. The only major shadow over Dick Legg's young life was cast in 1949, when he was fifteen. His brother Doug was driving a new car down a back road at high speed when he lost control of the vehicle, crashed, and was killed.
After Dick graduated—with no great distinction—from high school in the mid-1950s, he drove to Grayli
ng to enlist in the navy. Attending college apparently was never considered; there were no higher education degrees among the Legg men. But Dick's oldest brother, Don, had been in the service, and it seemed like a good place to learn a trade. Dick settled on the SeaBees, the navy's construction battalions, and was slotted to become a construction electrician. For the next two years, he shuttled around the eastern seaboard from one training program to another, learning the intricacies of electricity—how to harness it and how to fix the machinery when something went wrong. Then Legg learned that the army was looking for sailors and airmen to join its nuclear program; it sounded interesting. Like Byrnes, Legg was ambitious and confident—cocky even—in his abilities, and he didn't see a great future in being a run-of-the-mill electrician.

In early 1959, Legg and Byrnes arrived at Fort Belvoir to begin the training course in the nuclear program. Although they would later prove to be a fateful pairing, the two men didn't appear to have interacted much during their training in Virginia. One classmate recalls that few of the men socialized, as there just wasn't enough time. Byrnes and Legg, along with fifty-eight other men, were thrown into an intensive training course, with only four months devoted to academic courses before undertaking another four months of hands-on training in specialty duties at the fort's small training reactor, dubbed SM-1.
