Criticality safety technology in the next decade

The technology for critical safety has drawn heavily from weapons and reactor activities over the last fifty years. During the next decade, criticality safety is faced with many problems, such as storage of fissile material waste, depleted uranium application for criticality safety, regulatory improvement, experiments and benchmarks, burnup credit, dry storage of spent fuels, criticality safety calculations development, consensus on subcritical margins, etc. The author gives an overview of the technology of criticality safety in the next decade, and a preliminary discussion on some concerning criticality safety problems
