NRC restores expiration dates for renewed Turkey Point licenses
The Nuclear Regulatory Commission announced this week that it has restored the expiration dates of the Turkey Point nuclear power plant's units 3 and 4 subsequent license renewals (SLR) to July 19, 2052, and April 10, 2053, respectively.

Silicon carbide (SiC) fiber–reinforced SiC matrix (SiCf/SiC) composites, employing two SiC fibers, KD-I and KD-II, respectively, were fabricated by the precursor infiltration and pyrolysis process. A pyrocarbon coating was used as the fiber-matrix interface. In addition, the effects of heat treatment on the properties of the SiC fibers and SiCf/SiC composites were investigated. Results revealed marginal performance degradation of the KD-I and KD-II SiC fibers after heat treatment at 1100°C for 1 h. However, heat treatment at 1400°C for 1 h led to the decrease in the single-filament tensile strength of the KD-I and KD-II SiC fibers by 50.2% and 10.1%, respectively. In addition, the flexural strength of the SiCf/SiC composites, which were fabricated using the KD-I and KD-II SiC fibers, decreased by 49.6% and 15.9%, respectively. The difference in the composition of the KD-I and KD-II SiC fibers demonstrated that the SiC fibers and SiCf/SiC composites decreased by varying degrees.
