Food Irradiation and Agriculture










From the New York Times:
Pierre Lagoda pulled a small container from his pocket and spilled the contents onto his desk. Four tiny dice rolled to a stop.

“That’s what nature does,” Dr. Lagoda said. The random results of the dice, he explained, illustrate how spontaneous mutations create the genetic diversity that drives evolution and selective breeding.

He rolled the dice again. This time, he was mimicking what he and his colleagues have been doing quietly around the globe for more than a half-century — using radiation to scramble the genetic material in crops, a process that has produced valuable mutants like red grapefruit, disease-resistant cocoa and premium barley for Scotch whiskey.

“I’m doing the same thing,” he said, still toying with the dice. “I’m not doing anything different from what nature does. I’m not using anything that was not in the genetic material itself.”

Dr. Lagoda, the head of plant breeding and genetics at the International Atomic Energy Agency, prides himself on being a good salesman. It can be a tough act, however, given wide public fears about the dangers of radiation and the risks of genetically manipulated food. His work combines both fields but has nonetheless managed to thrive.

The process leaves no residual radiation or other obvious marks of human intervention. It simply creates offspring that exhibit new characteristics.

"You seek for knowledge and wisdom, as I once did; and I ardently hope that the gratification of your wishes may not be a serpent to sting you, as mine has been."

Mary Shelly
Frankenstein
Ah, Frankenstein...one of the most anti-technology books in existence.

If only you were legally allowed to burn down all the university nuclear engineering departments in the US. Wouldn't that be wonderful?

Mary Shelly was a rather gifted novelist, and her monster was completely fictional.

In the real world, genetically modified organisms mean that more people have access to disease free food that has been exposed to fewer pesticides. Those who decry the beneficial effects of radiation are effectively arguing that we should return to the nineteenth and prior centuries, when most children died before reaching their fourth birthday, and cities were dependent upon migration in from the countryside to sustain their populations as the urban mortality rate was much greater than the urban birth rate.

I am fortunate to live in an age when I can drink water without fear of cholera, eat raw produce without much fear of botulism, salmonella or pesticide poisoning. If Gunter wants to live a primitive lifestyle, good luck to him, perhaps we'll be relieved of his contributions to this blog when he gives up his computer. (BTW Gunter aren't you scared of the radiation from your computer monitor?) The vast majority of the world's population want to enjoy the benefits of modern technology, including those associated with nuclear technology.

Imagine how history might have been different if the technology had existed during Mary Shelly's lifetime. The Irish Potato Famine might have been averted.

Yep, better give up on those other technological innovations, too. Things like the wheel, the lever, refined metals, medicines, plastics, electricity, computers, aircraft, geez, it's just too dangerous. Never know what kind of MONSTERS (ahhhhhh!) those might spawn.

Making Clouds for a Living

Donell Banks works at Southern Nuclear’s Plant Vogtle units 3 and 4 as a shift supervisor in Operations, but is in the process of transitioning to his newly appointed role as the daily work controls manager. He has been in the nuclear energy industry for about 11 years.

I love what I do because I have the unique opportunity to help shape the direction and influence the culture for the future of nuclear power in the United States. Every single day presents a new challenge, but I wouldn't have it any other way. As a shift supervisor, I was primarily responsible for managing the development of procedures and programs to support operation of the first new nuclear units in the United States in more than 30 years. As the daily work controls manager, I will be responsible for oversight of the execution and scheduling of daily work to ensure organizational readiness to operate the new units.

I envision a nuclear energy industry that leverages the technology of today to improve efficiency…

Nuclear: Energy for All Political Seasons

The electoral college will soon confirm a surprise election result, Donald Trump. However, in the electricity world, there are fewer surprises – physics and economics will continue to apply, and Republicans and Democrats are going to find a lot to like about nuclear energy over the next four years.

In a Trump administration, the carbon conversation is going to be less prominent. But the nuclear value proposition is still there. We bring steady jobs to rural areas, including in the Rust Belt, which put Donald Trump in office. Nuclear plants keep the surrounding communities vibrant.

We hold down electricity costs for the whole economy. We provide energy diversity, reducing the risk of disruption. We are a critical part of America’s industrial infrastructure, and the importance of infrastructure is something that President-Elect Trump has stressed.

One of our infrastructure challenges is natural gas pipelines, which have gotten more congested as extremely low gas prices have pulled m…

Innovation Fuels the Nuclear Legacy: Southern Nuclear Employees Share Their Stories

Blake Bolt and Sharimar Colon are excited about nuclear energy. Each works at Southern Nuclear Co. and sees firsthand how their ingenuity powers the nation’s largest supply of clean energy. For Powered by Our People, they shared their stories of advocacy, innovation in the workplace and efforts to promote efficiency. Their passion for nuclear energy casts a bright future for the industry.

Blake Bolt has worked in the nuclear industry for six years and is currently the work week manager at Hatch Nuclear Plant in Georgia. He takes pride in an industry he might one day pass on to his children.

What is your job and why do you enjoy doing it?
As a Work Week Manager at Plant Hatch, my primary responsibility is to ensure nuclear safety and manage the risk associated with work by planning, scheduling, preparing and executing work to maximize the availability and reliability of station equipment and systems. I love my job because it enables me to work directly with every department on the plant…
