ANS Nuclear Cafe

The keynote speech of this morning's Opening Plenary was delivered to a large crowd by newly-installed Deputy Secretary of Energy Dan Brouillette, who followed ANS President Bob Coward's positive and hopeful, if wary, tone on the platform.

"There's no one I'd rather go into battle with," said ANS President Bob Coward to a packed Opening Plenary audience this morning, "than nuclear professionals," in reference to the stated purpose of ANS in advancing nuclear technologies.  Coward's very first remarks set the tone for a speech that was remarkably hopeful and bright given the recent blows that nuclear energy has suffered here in the United States.

What is an ideal energy source for electricity production? Students in my class say the ideal source must be plentiful, sustainable, inexpensive, reliable, safe, and produced right here in the United States thereby providing jobs.

The recent destruction of Puerto Rico's electric power infrastructure has been on the front page of every important news source at one time or another since the event near the end of September.  Recent reports show that perhaps as little as 10 to 15 percent of the island has electric power available now.

The Young Professionals Congress (YPC), the only joint American Nuclear Society (ANS) and North American Young Generation in Nuclear (NAYGN) meeting held anywhere, is a once every two years event held in Washington D.C. in conjunction with the ANS Winter Meeting.  For both of us, 2015 was our first opportunity to attend a YPC and after first hearing about it, we both immediately recognized the value and importance of the meeting.  As attendees and planners for 2015 and 2017, we are eager to share some of the great content associated with YPC 2017 and encourage you to attend. Remember, while YPC is a young professionals-run event, geared toward those early in their careers, there is plenty of content for the established professional to gain from attending.

As the month of October does its seasonal dance across the warm fall color spectrum, there's a bright cool color prominent on television shows and football fields: pink. October's pink represents breast cancer awareness month.

One of the things that's important to consider this week - National Clean Energy Week - is whether or not energy sources we depend upon are actually clean.  While we think of solar and wind energy as being pretty clean, we are also reminded that they are not reliable, and they do experience periods of time when they just don't work.  What we use to fill in that power gap is from sources we can control, independent of weather or time of day. These are sources we call "dispatchable" generating sources, because we can dispatch them and expect they'll answer the call to provide power.

Hurricane Irma shocked the country this week with images of wind and water that haven't been seen in some time along the hurricane-wary coastlines of the United States. Although people in those regions always have preparation for these storms somewhere in their minds, the two Florida Power & Light (FPL) nuclear plants-both of which powered through the hurricane-had both a background of design and preparedness to stand on as well as some recent, last-minute preparations.

Concerns about global warming and water scarcity have motivated many researchers to consider the potential for nuclear desalination, i.e., integrating a desalination plant with a nuclear power plant, as a means of producing drinkable water. There are numerous benefits to integrating a desalination plant with a nuclear power plant such as carbon-free electricity, low-marginal cost of generating electricity compared to fossil fuels, and a consistent power supply, unlike intermittent renewable electricity sources like wind and solar. Nearly 46 percent of the world's nuclear power capacity is within fifty miles of a coast according to data from the World Nuclear Association. In the U.S., several nuclear power plants are located near the coasts in states such as California and Florida where large-scale desalination plants have been constructed in the last decade. Thus, for locales with existing nuclear power plants and sufficient demand for desalinated water, nuclear desalination is an attractive option.

In a world fraught with loud, anti-nuclear voices, including a recent satirical news show that had a bit on nuclear waste, I've been pondering ideas that would provide a media platform to help counter the attacks on nuclear. While I am still a penniless grad student who lacks the budget of a weekly HBO nightly show, I believe I may have found a compromise. Starting today, Friday, September 1, 2017, I will be launching the bi-weekly podcast RadioNuclear.

People are bad at evaluating risks-especially from artificial, exotic, or invisible sources. When it comes to radiation, most people are not only bad at evaluating risks, but can be irrational to the point of being phobic about them. Interestingly, many of those who are frightened of radiation do understand that it's part of the environment-they're just scared of artificial radiation, mistakenly thinking that it's somehow different from natural radiation. One of my colleagues at the Ohio Department of Health took a phone call from a worried citizen in the early 1990s and tried to explain that the radiation exposure they were concerned about (from Ohio's uranium enrichment plant) was actually less than the radiation from a cross-country flight. "Yeah, but that's that good cosmetic radiation" was the caller's answer, to which my colleague simply replied with a sigh.

On Sunday night, the brilliant comedic satirist, John Oliver, presented a very funny, if basically wrong, segment on nuclear waste.

The next few years mark a turning point for commercial nuclear power in the United States, because after that there will be only a decade until 2030. That is when some fraction of the nation's aging nuclear fleet built in the 1970s and 1980s is expected be decommissioned when renewed licenses run out. Nuclear plants in the United States originally were given 40-year licenses and most have been renewed, and those expire in the 2030-2050 time range. Of course, this also assumes some plants cannot attain a second license renewal. If construction of new reactor units is not started soon, the existing plants could be shuttered before any new units come online. That is based on the 15-year construction timeline it takes for new nuclear construction in the U.S. This will have the unfortunate impact of leaving the nation without some of its reliable, clean, base-load energy that the country has relied on to provide 20-30 percent of its electrical generating capacity for the past 40 years.

The Democratic People's Republic of Korea (DPRK), often referred to as North Korea, is testing ballistic missiles capable of reaching California with a miniaturized atomic warhead. Neither component is fully developed yet.
