Energy analyst: Clean energy dreams come only with advanced nuclear
Wald
“We’re going to have to do things differently if we hope to trim the output of climate-changing emissions,” writes Matthew L. Wald in an essay recently published by the Breakthrough Institute. Wald is an independent energy analyst, writer, and Nuclear News contributor who formerly worked for the Nuclear Energy Institute and the New York Times. In the essay, he says that despite optimism surrounding progress in clean energy, consumption of fossil fuels is growing, and greenhouse gas emissions are increasing.
Wald suggests that this situation is unlikely to turn around until small modular reactors and other advanced nuclear technologies are demonstrated to be commercially viable.
Race to zero emissions? Wald notes that “global consumption of fossil fuels grew 1.5 percent last year.” Furthermore, “the fossil mix is getting worse; oil was up even faster than total fossil consumption, and demand passed 100 million barrels a day for the first time.

A new calibration has been developed for the electromagnetic flowmeters located on the 14-in. lines of the primary sodium coolant system of the Enrico Fermi Atomic Power Plant. This new calibration has incorporated the experimental hydraulic characteristics of the primary sodium coolant loop, the voltage outputs of the flowmeters on the 14- and 6-in. lines, and the original calibration of the flowmeters on the 6-in. lines. Utilizing this new calibration, the system pressure drop was found to vary as the 1.9'th power of the flow rate of the primary system. This relationship is in good agreement with theory. A comparison of the measured sodium flow using the new calibration with the calculated value from heat balance measurements showed good agreement, with an average deviation of 1.7%. (The “as-read” values from the flowmeters based on the previous calibration, which were developed using pump hydraulic characteristics and the pump affinity laws, were too high by an average of 10%.) This new calibration is now being used in the Fermi plant.
