1. A nuclear fuel cladding tube, comprising:
a container body that includes a wall portion separating inside and outside and is formed of a long-fiber-reinforced silicon-carbide composite material obtained by combining monofilaments of silicon carbide with a silicon carbide matrix, the wall portion having a thickness equal to a specific dimension; and
a lid configured to close at least one opening of the container body, formed of a material containing at least silicon carbide, and equipped with a wall portion separating inside and outside of the lid that has a thickness within a range of 1.2 to 1.9 times the specific dimension, wherein
the container body accommodates nuclear fuel of a nuclear reactor,
the lid is an end plug that closes the at least one opening at an end portion of the container body,
a shape of the lid is at least one of a shape of an outer stopper covering an outer periphery of the end portion of the container body and a shape of an inner stopper provided inside the at least one opening,
a bonding portion where the container body and the lid overlap is hermetically sealed,
a gap between the container body and the lid is sealed with an intermediate material under a state where the at least one opening is closed with the lid, the gap formed by overlapping the container body and the lid, and
at least the bonding portion is locally heated.
