Document Type and Number:
Japanese Patent JPS5838900
Kind Code:
A
Abstract:
A pond for the storage of hazardous materials, such as irradiated nuclear fuel elements, under water. Upper (8) and lower (6) impervious membranes extend without interruption beneath the floor (1) of the pond and the edges of the membranes lead into a trench (9) surrounding the pond. Any leakage through the floor is directed normally by the upper membrane (8) into the trench (9). The lower membrane (6) provides an additional impervious barrier in the event of a leak in the upper membrane (8) and again directs the leakage into the trench thereby avoiding contamination of the ground beneath the pond.
