Nuclear power station neutralization pool leak detection device

The invention belongs to the technical field of nuclear power station neutralization pool design, and particularly relates to a nuclear power station neutralization pool leak detection device. The cofferdams are arranged around the bottoms of the neutralizing tank A and the neutralizing tank B; drainage ditches are arranged at the bottoms of the neutralization tank A and the neutralization tank B and in the cofferdam; the tail end of the drainage ditch is provided with a sump; the neutralizing tank A and the neutralizing tank B are overhead through strip-shaped buttress foundations of the neutralizing tank; and a neutralization tank bottom overhaul space is arranged at the bottoms of the neutralization tank A and the neutralization tank B and between the strip-shaped buttress foundations of the neutralization tanks. The problems that nuclear power station neutralization pool leakage cannot be found in time and a plant foundation is possibly eroded are solved, a small amount of leakage can be found in time, le
