Abstract

The invention relates to the field of reactor equipment and discloses a spherical fuel element cask flask which comprises a flask body. The flask body is internally provided with an inner cavity, theinner cavity is provided with a vertical upper flask plug hole, a lower sphere storage hole and a suction passage, and the suction passage is horizontally positioned between the upper flask plug holeand the lower sphere storage hole and penetrates the flask body. A flask plug is arranged in the upper flask plug hole, the lower end of the flask plug is hermetically connected with an upper port ofthe lower sphere storage hole, the upper end of the flask plug is connected with a drive end of a step motor, and a seal cover in hermetical fit with the upper end of the flask body externally coversthe step motor and is provided with a gas pipeline communicated with the seal cover. Two ports of the suction passage are provided with seal parts respectively. The spherical fuel element cask flask has great shielding and sealing effects on radioactive fuel elements, and safety in storage and reusability are realized.

Description

technical field [0001] The invention relates to the field of reactor equipment, in particular to a spherical fuel element shielding tank. Background technique [0002] The fuel used in the pebble bed high-temperature gas-cooled reactor is a spherical element with a diameter of 60 mm, which is circulated through the ball flow pipeline and equipment without reactor failure. When the ball system and equipment fail, it is necessary to take out the radioactive fuel elements, damaged elements or debris in the pipeline or equipment, and because the number of fuel elements or debris to be taken out under fault conditions is very small, it is necessary to be able to Provides radioactive shielding, easy handling, airtight, reusable containers. Contents of the invention [0003] (1) Technical problems to be solved [0004] The object of the present invention is to provide a spherical fuel element shielding tank to solve the problem of taking out and storing radioactive fuel element...
