Abstract

To provide a stratum disposal facility capable of efficiently transporting a waste package.SOLUTION: A stratum disposal facility 1 comprises: a disposal tunnel 21 in which a waste package 11 containing radioactive waste is placed and disposed of; a communication tunnel 9 that is connected to the disposal tunnel 21, and transports the waste package 11 to a connection part 55 with the disposal tunnel 21; and a first transport vehicle 47 that carries the waste package 11 and moves through the communication tunnel 9 using a pneumatic conveyance system. The first transport vehicle 47 can separably carry a second transport vehicle 49 that moves through the disposal tunnel, and an extension directions of the communication tunnel 9 and the disposal tunnel 21 at the connection part 55 are aligned.SELECTED DRAWING: Figure 7
