South Korea looks to Southern and NuScale
This week, the United States and South Korea have taken two steps toward deepening their nuclear partnership through two notable announcements. First, the majority-state owned Korea Hydro & Nuclear Power signed a memorandum of understanding with Birmingham, Ala.–based Southern Nuclear.

A project to realize, in several years, a W/Cu divertor on Experimental Advanced Superconducting Tokamak (EAST) with ITER-like plasma-facing component (PFC) configuration was launched at Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP) in 2010. The ITER-like configuration should withstand the rapid increase in particle and power impact onto the divertor and demonstrate the feasibility of the ITER design under practical long-pulse tokamak plasmas. The project could help not only EAST experiments, but also realize ITER PFC technology validation and bring answers in a timely manner for the ITER full-W divertor for the nuclear phase. Southwest Institute of Physics (SWIP) will have 10% of the first wall (FW) procurement package of the enhanced heat flux (EHF) type. The materials have been developed and characterized according to the ITER-grade material specifications, including vacuum hot pressing (VHP)-Be, CuCrZr alloy, and 316L(N)-IG forged blocks, and qualification testing of the VHP-Be tiles joining to the CuCrZr heat sink by hot isostatic pressing (HIP) has been carried out. Some Chinese universities have started to explore new grades of W materials, e.g., carbide or oxide dispersion strengthened fine grain W materials, and investigated their behavior under high heat loads.
