Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

Equation-of-state experiments using VISAR require the refractive index of undoped glow discharge polymer (GDP) and Ge-doped GDP at 532-nm-wavelength light. The index was measured with two different techniques. The first technique used measurements of pulsed laser reflections off a GDP foil suspended in refractive index fluid standards. Fluids with different indices were replaced until minimum reflection was achieved; this occurred at the matching index of the fluid and GDP film. The index of the correct matching fluid (or fluid mixture) was measured with an Abbé refractometer to produce nD (the refractive index at sodium D line, 589 nm) and was corrected for wavelength using manufacturer-supplied Cauchy equation coefficients. The second technique used interferometry to measure fringe shift over GDP and Ge-GDP bumps when submerged in various refractive index fluid standards. The fringe shift was minimized when matching the indices of the fluid and film. The refractive indices at 532 nm were 1.563 and 1.570 for undoped GDP and Ge-doped GDP, respectively.
