NEI Nuclear Notes

Energy experts are at war over a radical assertion that by mid-century the United States will be able to meet all its energy needs with wind, solar and hydro power. The claim was made in 2015 by four academic researchers , led by Mark Z. Jacobson, for the continental United States, and it asserts that those renewables will replace not just the coal and natural gas used to make electricity, but also the gasoline and diesel that run cars and trucks, and the gas used in home heating. The paper is regularly cited by environmentalists who claim that the current fleet of U.S. nuclear reactors could close without any consequences to grid reliability. But last week, a group of prominent researchers, some from Stanford and UC-Berkeley, and others from the National Oceanographic and Atmospheric Administration, Carnegie Mellon and other mainstream organizations, published a second paper that said that while they support the expanded use of renewables, Professor Jacobson et al. were dreaming....

A group that includes oil and gas companies in Pennsylvania released a study on Monday that argues that twenty years ago, planners underestimated the value of nuclear plants in the electricity market. According to the group, that means the state should now let the plants close. Huh? The question confronting the state now isn’t what the companies that owned the reactors at the time of de-regulation got or didn’t get. It’s not a question of whether they were profitable in the '80s, '90s and '00s. It’s about now. Business works by looking at the present and making projections about the future. Is losing the nuclear plants what’s best for the state going forward? Pennsylvania needs clean air. It needs jobs. And it needs protection against over-reliance on a single fuel source. What the reactors need is recognition of all the value they provide . The electricity market is depressed, and if electricity is treated as a simple commodity, with no regard for its benefit...

Researchers at the Penn State College of Medicine  recently published a study  claiming that analysis of thyroid tumors showed tissue differences, based on where the patient lived. People who lived near Three Mile Island at the time of the 1979 accident had tumors more likely to have come from radiation exposure than people who developed thyroid cancer while living elsewhere, according to the researchers. Science is advanced by experts who publish new findings, and readers who then evaluate the conclusions and how they fit into the existing body of knowledge. We welcome all contributions to knowledge. But scientific studies should be read with care, so their claims can be understood, and so we can determine how the findings fit with what was previously understood. And these findings don’t fit. Three Mile Island Nuclear Generating Station Despite what a reader might assume from a news headline, this paper does not assert that Three Mile Island is the cause of any canc...
