Abstract

Fluid flow by pass systems. For application in the air outlet system of a nuclear reactor in which it is required to pass all the air through a carbon filter if iodine isotopes are leaked into the air. The air normally flows through one pipe into a chimney, but if required, this pipe is sealed imperfectly, by two valves, and the seal perfected by a fluid at higher pressure pumped into the region between the two valves. All the air then flows through a by pass tube contg. the filter.
