The Rift (14 page)

Jameel made a face. He had complained long and hard about the Cubs’ preseason trade.

The refueling was relatively simple, but the scale of it was always impressive. Larry enjoyed his visits to the containment structure, and since the reactor was shut down, and everyone else going through routine maintenance checklists, he had nothing more urgent at the moment than to suit up, enter the containment building, and play tourist.

The bright yellow clean suit he wore, complete with boots and gloves and a hood over his head, had nothing to do with protecting himself from radiation— the water flooding the space above the reactor would do that. The suit was to keep him from contaminating the water with one of his accidental byproducts, such as, for example, a hair. The demineralized water that was used to cool the reactor and its fuel was carefully maintained in order to make certain that it gave no chemical or mechanical problems.

The refueling machine began to hum as chains rattled in. Larry put his hands on the rail, looked down. The machine was large and moved back and forth on tracks placed over the water-filled refueling cavity. Its operators sat atop it, peering into the watery depths below.

Glimmering in the glow of floodlights, the squat silver-metal form of a fuel assembly began its descent into the reactor. Its glittering image was broken by the refraction of the little wavelets in the pool. The chains ceased to rattle, and the sound of the engine died. Electric motors gave brief whines. Jameel signaled to another of his crew. There was a subdued metallic clang, and then chains began to rattle again as the hook that had lowered the fuel assembly into the reactor withdrew.

The refueling process was nearing its end. Over eight hundred fuel assemblies needed to be moved— most were just moved within the reactor, but a third had to be replaced completely, the old assemblies moved through an underwater channel to the Auxiliary Building for storage, while new assemblies were carried the other way.

With an urgent hum of electric motors, the refueling machine began to move, sliding on its tracks toward the fuel channel, where it would pick up another fresh fuel assembly for movement into the reactor.

Larry smiled down at the operation and thought of horses.

Even with his fifty-five years and his degree in nuclear engineering, Larry Hallock still considered himself a cowpuncher. He had been raised on a ranch near Las Vegas, New Mexico, a long, rambling adobe building, built over generations, with a tin roof and a homemade water tower. Every summer afternoon, as the thermals rose from the valley floor, cool air would flow down from the Sangre de Cristo Mountains and bring with it the scent of the high meadows, the star flowers, white mountain daisies, and purple asters, the flowers that flourished in the brief growing season at ten thousand feet. For Larry, this was the perfume of paradise. Sometimes, even now, he woke from a dream with the scent in his nostrils.

When he was fourteen, his father had called him, his brother, and his sister into the little office from which he ran the ranch business, the mud-walled room with its old rolltop desk, well-thumbed ledger books, and Navajo rugs. His blue eyes gazed at them all from his leathery face.

“Do you love this business?” he asked. “Do you want to ranch for the rest of your lives?”

All three siblings nodded.

“Well, then,” their father said, “you better all go to college and become professionals, because it’s the only way you’re going to be able to afford to keep this place alive.”

They had taken their father’s advice to heart. Larry’s younger brother Robert was a doctor in Santa Fe. Larry had become a nuclear engineer. Both considered themselves cowboys at heart, and spent as much time as possible in New Mexico doing ranch work. And their older sister Mimi, who still lived on the ranch, commuted in her Chevy pickup truck to her law practice in Las Vegas. She had raised her children to carry on after her, which was more than Larry had managed— his daughter worked in biostatistics, whatever those were, in North Carolina’s Research Triangle, and his son studied Chinese literature at the University of Chicago. Both places were a long way from New Mexico, and when Larry thought about it he felt a breath of sadness waft through his heart.

He was remembering a grulla mare named Low Die that he had ridden when he was maybe twelve. She would set down wonderfully on her hocks, but for some reason she would not fall off to the right as well as she fell off to the left. When she spun to the left it was a thing of beauty, but when he wanted her to cut right, for some reason her coordination fell apart, and there were strange, unpredictable hesitations in her movement. It was almost as if she were
afraid
to turn right.

Experience suggested that such a fault might be the result of a spinal injury or deformity. But after a thorough examination it was concluded that Low Die’s spine was in perfectly fine shape.

So Larry had worked that strange horse patiently for weeks. He would work her first on moves that she could do well, moves in which she had confidence. He would praise her lavishly for every successful maneuver. Then he would run her for a while, so that she’d get tired and not think so much, just respond to the touch of his feet and hands.

And then he’d start turning Low Die in wide circles to the right. And the circles would get smaller and smaller until, eventually, she was falling off to the right just as he wanted.

That was how you solved a problem. You broke it down into pieces, and you solved the pieces one at a time. With patience, you could get anywhere, even into the dimwitted brain of a horse.

Low Die. A beautiful cutting horse. He’d ridden her for years.

“You see that homer in the Red Sox game?” Jameel called up from his post on the refueling machine.

“Oh yeah,” Larry said. “A thing of beauty.”

In Larry Hallock’s estimation, the problems involved in managing nuclear power were not dissimilar to those involved in training a horse. The universe operated by certain principles, and these principles could be applied anywhere, by anyone of sufficient skill and intelligence. The statement of a problem contained within itself the elements of its own solution. You needed to break the problem into its parts, to work on each in its turn. You needed patience and a sense of perspective. Humor didn’t hurt, either. Sometimes you found yourself turning circles, as Larry had when he was training Low Die, but you needed to realize that even when you were turning in circles, you were still getting somewhere.

Poinsett Landing was a complex system, and its complexities were increased by its massive scale. The statistics themselves were vast enough to strain the imagination. The power station required a dozen years to build, 1,800 miles of electrical wire, 100 miles of pipe, 125 miles of conduit, 16,000 tons of steel, 29,000 tons of rebar, and nearly 150,000 cubic yards of concrete. The reactor vessel, the steel pressure cooker in which nuclear fission took place, stood eighty feet high, its sides were over eight inches thick, and it weighed two million pounds. It sat in a steel-and-concrete containment structure twice as high as the reactor vessel, three and a half feet thick and sheathed with stainless steel, built so strongly that it could withstand the 300-mile-per-hour winds of a tornado, or even the impact of a Boeing 747 being deliberately crashed, by suicidal terrorists, into the building from above.

But when you got right down to it, a nuclear power station, with all its vastness, was a very simple system compared to a biological organism such as a horse. Its size was a measure of its relative inefficiency— it was enormous because people hadn’t worked out how to generate power with the compact efficiency of a biological organism. Animals, with their complex organization and chemistry, their mobility and intelligence, were marvels of concentrated efficiency. They were brilliant engineering. By comparison, Poinsett Landing Power Station, complex as it was in certain ways, was simplicity itself.

Which was good, as far as Larry Hallock was concerned. An animal, be it a human being or a horse, was intricate enough so that when something went wrong with it— a broken leg, cancer, mental illness— it was difficult to fix. The problems at Poinsett Landing were, by comparison, simple.

Take the problem of Poinsett Landing’s site, for example.

The massive containment building, with its huge steel nuclear reactor, its three-foot-thick concrete walls sheathed with steel, had presented a particular problem to the plant’s designers. A large, heavy building requires a large, stable foundation. The best foundation of all is solid bedrock.

But bedrock is at a premium in the Mississippi Delta. The land consists of layers on endless layers of mud laid down by repeated floodings of the great river. The mud can extend thousands of feet below the level of the land. There is no bedrock on which to safely build large structures and anchor them against the dangers of their own weight.

But the Delta land was cheap, much cheaper than elsewhere. With the plant requiring two thousand acres of land, the price of the land was a prime consideration in the plant’s cost. The plant’s designers were asked to solve the problem of building the huge, heavy structure on land that would not support it.

The engineers simply built their own bedrock beneath the containment structure, a huge mat of concrete laced with a webwork of steel. This pad was twelve feet thick and sat in the rich Delta land like a paving stone, and it supported the vast two-million-pound weight of the reactor vessel, the steel-and-concrete containment structure, and the control facility, which leaned against the featureless containment building like a child clinging to his mother’s hip.

It was a tried and true technique, Larry knew, often used in areas like Miami Beach, where large buildings had to be constructed on shifting sand. It had the advantage of simplicity. The huge pad would be there forever: after it had been set in the Delta soil, no one would ever have to think about it again.

“Waaal,” Larry Hallock said, “let’s get this sucker warmed up.” He stood behind his metal desk, perched on its platform above the rest of the control room. The lights and indicators, which were on panels above the operators’ heads, were at eye level for Larry. He scanned them, noted the orderly rows of green and red lights, nothing amiss.

The room looked like the headquarters of a James Bond villain. Metal surfaces, control panels, thousands of buttons, displays with blinking lights. All painted in avocado green and harvest gold, the signature colors of the 1970s, the decade in which the room was designed and built.

Larry wondered if a more recent control room would be painted different colors. Would a nineties control room, he wondered, be Hunter Green?

A box from Dunkin’ Donuts on one of the computer monitors near the door spoiled the illusion of a supervillain’s retreat. Larry helped himself to a chocolate doughnut.

“We’re set,” Wilbur said, having, from his lower perspective, just scanned the displays himself.

“Let’s give ’er the spur,” Larry said.

You didn’t want to start up a nuclear reactor with a bang. It would take almost a full day to get the reactor on line, to first increase temperature within the reactor, then start pushing steam through the turbine to generate enough power to put on the grid.

It was like handling a big horse, one that could stomp you flat just by accident, just because you weren’t paying attention. You just wanted to give it a little kick with your heels, get it moving without startling anyone, least of all yourself.

It was tricky enough so that Larry wanted to be in the control room for the procedure, just in case Wilbur, who was the control room operator and would be giving the orders, needed some backup. Larry was the shift supervisor, in charge of everything going on at the plant during his shift. Wilbur was in charge of the reactor under Larry’s supervision.

Larry and Wilbur watched the displays as boron carbide control rods were partially withdrawn from the reactor, as neutrons began to multiply and the chain reaction began. The scent of roses floated through the control room: Larry had bought a massive vase of yellow roses for his wife, who had a birthday today. He moved the roses out of his line of sight, sat in his wheeled metal chair, and thought about putting his boots up on his desk, but decided not to.

Larry put a hand on the scarred metal surface of his desk and felt a little tremor through his fingertips. Pumps, distant but powerful, steam moving through massive pipe. Valves tripped open as pressure built.

Words floated to Larry as he watched the displays. Something about Ole Miss and the Rose Bowl.

No day was complete without talk of football. Not in Mississippi.

One of the operators interrupted the talk of the gridiron in order to make a report. “Holding at ten percent.”

Ten percent was one of the check points, where all concerned would be looking at their instruments to make certain that everything was operating normally.

Larry scanned the displays over the operators’ heads. Everything looked fine.

“You going to do anything special for your wife’s birthday, Mr. Hallock?” Wilbur asked.

“Tonight we’ve got reservations at the Garden Court in Vicksburg.”

“Getting some of that Creole food, huh? It’s too hot for me.”

Larry grinned. “You best not try New Mexico chile, then.”

“I don’t even put pepper on my grits in the morning.”

Larry looked at the displays, at the lights shifting, red and green.

“Bland is boring,” he said. “Me, I like a little spice in my life.”

“Everything checks, Larry,” Wilbur said. “Still holding at ten percent.”

“Waaal,” Larry said, “let’s goose her a little.”

Boron carbide rods slid smoothly out of the reactor. Neutrons turned water to steam. Steam shot under unimaginable pressure through massive thirty-six-inch pipes.

Larry put his boots on the desk and thought about horses.

Four shocks of an Earthquake have been sustained by our town, and its neighborhood, within the last two days. The first commenced yesterday morning between two and three, preceded by a meteoric flash of light and accompanied with a rattling noise, resembling that of a carriage passing over a paved pathway, and lasted almost a minute. A second succeeded, almost immediately after, but its continuance was of much shorter duration. A third shock was experienced about eight o’clock in the morning, and another today about one.
