NN Asks: How do a meteorologist’s forecasts shape nuclear utility planning?

July 6, 2022, 12:06PMNuclear News

Jennifer Call, Meteorologist:
When you think of a meteorologist, what is the first thing that comes to mind? For many it is your local TV meteorologist delivering a weathercast for the 5 o’clock news, or perhaps a meteorologist at the National Weather Service issuing severe storm warnings. But did you know that utilities rely on meteorologists for daily support?

Jennifer Call (jtcall@tva.gov) is an American Meteorological Society Certified Consulting Meteorologist (CCM) and an atmospheric analyst for the Tennessee Valley Authority. She serves on the ANS Standards Board and is the Atmospheric Subcommittee chair under the Environmental and Siting Consensus Committee.

Ultra Safe Nuclear Corporation (USNC), an advanced reactor and reactor fuel developer, announced last week that it plans to begin operations this summer at its Pilot Fuel Manufacturing (PFM) facility in Oak Ridge, Tenn., pending the receipt of the requisite state and local permits. The facility is located in the East Tennessee Technology Park, site of the Manhattan Project’s K-25 gaseous diffusion plant. USNC purchased an 8.7-acre site—which included a preexisting industrial building—from Heritage Center LLC in 2021.

The Nuclear Regulatory Commission has granted Dominion Energy’s request for an increase in the generating capacity of Millstone-3. The Richmond, Va.–based utility had applied for the power uprate last November, requesting an increase of approximately 1.6 percent.

NRC staff determined that Dominion could safely increase the reactor’s heat output, primarily through more accurate means of measuring feedwater flow, according to a November 18 press release. The NRC’s safety evaluation focused on several areas, including the nuclear steam supply systems, instrumentation and control systems, electrical systems, accident evaluations, radiological consequences, fire protection, operations and training, testing, and technical specification changes.
