Embodiment Construction

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] The packaging shell is cylindrical and consists of two parts: an upper shell 6 and a lower shell 1. The upper shell 6 and the lower shell 1 are hollow structures, both inside and outside are metal shells, and the interior is filled with 3# aluminum silicate fiber 2, 3# aluminum silicate fiber plays the role of buffering and heat insulation. The filling density of 3# aluminum silicate fiber in the upper and lower cladding is 180±15%kg / m 3 .

[0025] When filling, the aluminum silicate fiber is cut into circular plates or circular rings according to the filling area, and then laminated into the filling area one by one. Partial discontinuous areas are filled with loose blankets. Each layer of aluminum silicate fiber blanket is pressed into a special layer. After the tool is compacted and filled, the parts are weighed to ensure that the fi...

Abstract

The invention relates to a packaging shell for a uranium tetrafluoride powder container with the storage and transportation abundance not exceeding 20%. The packaging shell is cylindrical and is composed of an upper cladding shell and a lower cladding shell, the upper cladding shell and the lower cladding shell are of a hollow structure, the interior and the exterior of the upper cladding shell and the interior of the lower cladding shell are metal shells, and the interior of the inner metal shell and the interior of the outer metal shell are filled with aluminum silicate fibers; the upper pressing plate is welded with the upper cladding inner and outer metal shell, the lower flange is welded with the lower cladding outer metal shell, the lower pressing plate is welded with the lower cladding inner and outer metal shell, the upper cladding and the lower cladding are connected through the upper flange and the lower flange by using a fastener, a sealing gasket A is arranged between the upper pressing plate and the lower pressing plate, and a sealing gasket B is arranged between the lower flange and the upper flange. Lifting bolts are installed on the upper flange and the lower flange and welded to the upper flange, and a supporting heat insulation assembly is arranged at the bottom of the lower cladding. The packaging shell can also be used for storing and transporting triuranium octaoxide powder and uranium dioxide powder containers with abundance not exceeding 20%.

Description

technical field [0001] The invention relates to a packaging shell for storing and transporting uranium tetrafluoride (powder) containers with an abundance of not more than 20%. , Uranium dioxide (powder) container. The packaging shell is suitable for road and rail transportation of the above three uranium compound (powder) product containers, and belongs to a uranium compound powder transportation system with an abundance of no more than 20%. Background technique [0002] The packaging shell is mainly used for the transportation of uranium tetrafluoride (powder) between the nuclear fuel element plant and the user. According to the requirements for radioactive materials in GB11806-2019 "Regulations for the Safe Transport of Radioactive Materials", the transport package of uranium tetrafluoride (powder) container must pass the corresponding safety test verification before it can be transported. [0003] At present, there is no packaging shell for storage and transportation o...
