Vistra’s Perry nuclear plant approved for license renewal
Texas-based Vistra Corporation has announced that its license renewal application for the Perry nuclear power plant was approved by the Nuclear Regulatory Commission. The plant first connected to the grid in 1986 and is still operating under its original 40-year license, which was set to expire next year.

C.2. Creep Property | Status of Metallic Materials Development for Application in Advanced High-Temperature Gas-Cooled Reactor / Material | doi.org/10.13182/NT84-A33429
Articles are hosted by Taylor and Francis Online.
Creep rupture tests on six candidate alloys for intermediate heat exchangers of high-temperature gas-cooled reactors were carried out at 1173 to 1323 K in helium with small amounts of H2, CH4, CO, and C02, and at 1173K in H2 + 15% CO + 5% C02. The creep rupture strengths of each alloy were scarcely different at 1173 K in both environments. At higher temperatures in helium environments, the degradation of the creep rupture strengths appeared in carbide-strengthened alloys because of decarburization. The alloy, which mainly uses α-W as a strengthener, showed stable creep rupture strength up to 1323 K in spite of severe decarburization.
