Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

Framatome, KHNP to investigate producing Lu-177 in South Korea
Framatome and Korea Hydro & Nuclear Power (KHNP) announced the signing of a memorandum of understanding to explore the possibility of producing the medical isotope Lutetium-177 at KHNP’s Wolsong nuclear power plant in South Korea. The companies also will investigate the feasibility of using the plant to support Korean production of medical radioisotopes in the future.

The ITER poloidal field (PF) coil power supply system consists of 14 basic converter units that feed six superconducting coils. The converter unit is the complicated, challenging, and unique system to realize four-quadrant operation compatible with the superconductive load and the demand for plasma control. This paper describes the final design of the control strategies, which are implemented in the local controller of the PF converter system. They are zero crossing current control strategy in circulating operation mode, current balance control strategy in parallel operation mode, and hysteresis band control strategy in mode transition. In addition, the performance of the control system is demonstrated by the analysis, and the control strategies are validated by the simulations and corresponding tests.
