The process is complete when all critical characteristics are verified and the item is designated for use as elri basic component. As far as the dedication process goes, the requirements for it are somewhat loose. This paper will review these aspects of adopting digital control technology and improvements in plant monitoring and network communications to nuclear power plants.
