Deep Isolation asks states to include waste disposal in their nuclear strategy
Nuclear waste disposal technology company Deep Isolation is asking that the National Association of State Energy Officials (NASEO) consider how spent nuclear fuel and radioactive waste will be managed under its strategy for developing advanced nuclear power projects in participating states.

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.
