Relating to a study regarding the feasibility of integrating into the electric grid facilities that use nuclear energy to generate electricity.

HB 3423 requires The University of Texas System to study the feasibility of adding nuclear energy facilities (including both fusion and fission reactors) to Texas' electric grid. The study must compare costs and benefits, with results reported to the legislature by September 1, 2026. This bill does not change any laws or policies - it only mandates a study to inform future decisions. It expires December 1, 2026, and affects no specific groups beyond directing the UT System to conduct the analysis.
