Wright officially sworn in for third term at the NRC
The Nuclear Regulatory Commission recently announced that David Wright, after being nominated by President Trump and confirmed by the Senate, was ceremonially sworn in as NRC chair on September 8.
This swearing in comes more than a month after Wright began his third term on the commission; he began leading as chair July 31. His term will conclude on June 30, 2030.

A scaled model boiling water reactor (SMBWR) uses water at 0.095 MPa in a transparent heated channel 0.5 m in length with four electrical heated fuel simulator rods. The axial void profile in the channel is measured using conductivity probes. The boiling channel exhibits bubbly and churn flow regimes. In the present study, the bubbly-churn regime transition is investigated using the variance, kurtosis, and skewness of the probability density function (pdf) derived from the conductivity measurements. The positioning of five conductivity sensors along the boiling water channel allows examination of the gradual changes in the flow regime characteristics. The results indicate it is possible to detect the bubbly-to-churn flow regime transition using the pdf distribution attributes of the conductivity probes.
