Pool leak detection tube

The utility model belongs to the spent fuel receiving and storage technology filed, and particularly relates to a pool leak detection tube. The utility model aims to solve disadvantages in the prior art and provides a pool leak detection tube which solves problems that the pool leakage position cannot be determined because of accumulation water at a window, a leakage quantity problem and blocking of a leakage detection header pipe. The scheme of the pool leak detection tube is that: the pool leakage detection pipe consists of leakage detection branch pipes and header pipes; each pool leakage detection branch pipe is inclined toward the header pipe in each pool and is welded on the header pipe; and a window water outlet is higher than the leakage detection header pipe; and the four leakage detection header pipes in a pool bottom leakage detection chamber the four leakage detection header pipes in a pool bottom leakage detection chamber are arranged from high to low on a G065 pipe gallery after passing through
