Nuclear Balance-of-Risks

Nuclear reactor technology has allowed the world-wide use of nuclear reactors for energy production. With the world faced with mounting carbon dioxide levels and global warming a concern, nuclear energy provides a low carbon emission alternative to traditional energy sources (World Nuclear Association and MIT study). This aspect of nuclear energy makes it a very attractive energy alternative. With President Obama wishing to expand the United States nuclear power plant program, the question becomes an issue of balance-of-risks.

Accelerating nuclear reactor development provides a low carbon emission energy source; however there is risk associated with the use of nuclear materials. If we do not take advantage of nuclear’s low carbon footprint and instead pursue other, higher carbon footprint strategies, we risk exacerbating global warming issues. There are other options, as well, such as cleaner technologies, emerging energy technologies and reducing fertility rates to decrease population size.

We seek to understand the low probability, high impact, long-tail risks associated with the use of nuclear materials. Since the dawning of the nuclear age, mankind has worked to harness the power of the atom. There have been many benefits from the use of radionuclides. However, there are risks as well.

Risk areas to consider in looking at nuclear energy include:

• Economic, including Externalities
• Design and Construction
• Natural Disasters
• Operations and Management
• Political and Regulatory
• Terrorism, War and Sabotage
• Radioactive Waste Treatment and Storage

We have had experience with nuclear accidents that display some of that high impact, long-tail risk. Previous blog articles have discussed Chernobyl, Three Mile Island and Fukushima (3/12/11, 3/25/11 and 3/28/11).

We have seen historical flooding on the Missouri River which threatened Fort Calhoun Nuclear Plant and Cooper Nuclear Plant in Nebraska. Recently we have seen the large Las Conchas Wildfire threaten the Los Alamos Energy Department facility in New Mexico.

These situations, including those situations where facilities were threatened but not breached, are all reminders that radiation is a serious risk and not simply an abstract probability.
