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.

Sliding mode control is an effective methodology for controlling systems with variable structures, providing a systematic approach to the problem of maintaining stability and consistent performance in the presence of modeling imprecision, uncertainties, and disturbances. The observation problem of the uncertain and nonlinear nuclear systems is investigated by using sliding mode observers (SMOs). Three different applications with uncertainties are under consideration: point reactor kinetics equations, nonlinear xenon dynamics, and a U-tube steam generator system. Numerical results are presented to illustrate the effectiveness of the SMO.
