The development of nuclear science and technology and the peaceful utilization of nuclear energy are one of the greatest achievements of human beings in the 20 th century. However, with the continuous development of nuclear energy and nuclear technology, particularly since the middle of the last century, human development utilized nuclear fission energy to generate large amounts of high-level solid waste. High-level radioactive waste liquid solidified bodies generated by the post-treatment of the spent fuel, the spent fuel discharged by a nuclear power station and prepared for direct disposal in one-time pass and the like belong to high-level radioactive solid wastes.

Since high level waste contains nuclides that are highly radioactive, highly calorific, highly toxic, and have long half-lives, it is desirable to isolate them from the human living environment for a long period of time and reliably. How to safely dispose of high-level waste has become a difficult problem of the current radioactive waste management, has attracted extensive attention of the international society, and all nuclear countries in the world regard the safe disposal of high-level waste as a strategic task of ensuring the sustainable development of nuclear industry, protecting human health and protecting environment. The development process of nuclear energy in advanced countries in the world shows that the problem of safe disposal of radioactive waste, especially high-level radioactive waste, has become one of the factors restricting the sustainable development of nuclear energy. Therefore, the safe disposal of high-level waste is a major problem related to the homeland environment, public safety and health and sustainable development of the nuclear industry, is also an essential important link in the activity of the nuclear industry, and the disposal problem of high-level waste must be researched and properly solved.

At present, high level solid waste disposal libraries of various countries in the world are still in site selection and laboratory stages, and high level solid waste generated in the nuclear fuel circulation process is basically in a temporary storage state. In order for these wastes to be conveniently transported, buffered, disposed of, and ultimately disposed of, they must be safely packaged, buffered.

The thickness of the barrel bottom is 10 mm.

8 reinforcing ribs are arranged on the periphery of the barrel body.

The shift forks are 3 in number, and the turnplate is uniformly arranged for a circle.

The bottom of the barrel is a square stainless steel plate; the periphery of the steel plate is rounded, and four corners of the steel plate are provided with guide mechanisms.

The invention has the following remarkable effects:

(1) 8 strengthening ribs are arranged around the barrel body to enhance the strength of the barrel body.

(2) The barrel bottom is a square stainless steel plate (with the thickness of 10mm), so that the barrel bottom is prevented from deforming when waste is filled in the barrel.

(3) The periphery of the barrel bottom steel plate is rounded, and the four corners are provided with guide mechanisms, so that the waste barrel is ensured not to rotate when being transported on a roller way.

(4) The lip-shaped sealing ring is arranged on the flange, and when the barrel cover is in butt joint with the barrel body, the sealing of the inner space of the barrel body is ensured, and the radioactive substances are prevented from overflowing.

(5) The upper pressure plate, the lower pressure plate, the rotary disc and the central plate are connected into a whole through bolts, the outer sealing ring and the inner sealing ring are arranged in the T-shaped groove of the rotary disc and the central plate, when the rotary disc rotates, the sealing of the inner space of the barrel body can be ensured, and the radioactive substances are prevented from overflowing.
