PURPOSE: A tritium measuring and distributing apparatus is provided to improve the accuracy and the reliability of a tritium measuring operation by optimizing the size of a measuring container and the frequency of a measuring operation. CONSTITUTION: A plurality of measuring containers(3) accurately measures tritium. A tritium storing and a supplying container(2) stores tritium extracted by a tritium extracting unit. A tritium storing container(4) stores distributed tritium. A tritium analyzing unit(5) measures the purity of tritium. A manifold(6) connects tritium-related containers and the measuring containers. A pump circulates gas in the manifold. A tritium purifying container collects tritium remained the measuring containers and the manifold.
