Abstract

The invention relates to a spent fuel transportation container comprising a stainless steel outer cylinder (2), a stainless steel inner cylinder (3), a lead layer (5), a bottom end (1) and an upper end (6). The container is characterized in that tin layers (13) are provided on the inner wall of the outer cylinder (2) and the outer wall of the inner cylinder (3). According to the invention, the fitting rate of applied lead between the stainless inner and outer cylinders can be higher than 97.5%, such that product quality is ensured.

Description

Spent fuel transport container
Technical field
The invention belongs to nuclear fuel container, particularly a kind of spent fuel transport container transporting nuclear reactor RY-1 type.
Background technology
Because spentnuclear fuel has the decay heat of very high radiation energy and drawing crack sell of one's property life, so container must have certain screening ability and the capacity of heat transmission, require the in-built spentnuclear fuel of container inner core for this reason, between urceolus and inner core, lead layer is installed, laminating rate between lead layer and stainless inner/outer tube surface must reach more than 80% just for qualified, domestic experience of not warding off lead at stainless steel surfaces, because lead is special poor to the wetting state of stainless steel surfaces, add and ward off plumbous difficulty, both at home and abroad can for reference and reference without detailed data.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of and ward off at stainless inner/outer tube wall surface the spent fuel transport container that lead reaches more than 80%.
The technical scheme that technical solution problem of the present invention adopts is: a kind of spent fuel transport container, comprises stainless urceolus, inner core, lead layer, bottom head and upper end, it is characterized in that hanging one deck tin layers on the inwall of urceolus and the outer wall of inner core.
The invention has the beneficial effects as follows: this invention is warded off plumbous laminating rate and reached more than 97.5% between stainless steel inner/outer tube, ensure that the quality of product.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, illustrate with embodiment.
Fig. 1 is the sectional front view of spent fuel transport container.
In figure: the head of 1-bottom; 2-urceolus; 3-inner core; 4-vent port; 5-lead layer; 6-upper end; 7-gas port lid; 8-exhausr port; The upper hanger of 9-; Hanger under 10-; 11-bottom; Lead layer at the bottom of 12-; 13-tin layers.
Embodiment
Embodiment, with reference to accompanying drawing, a kind of spent fuel transport container, comprises stainless urceolus 2, inner core 3, lead layer 5, bottom 1 and upper end 6, it is characterized in that hanging one deck tin layers 13 on the inwall of urceolus 2 and the outer wall of inner core 3.Between the tin layers 13 that inner core 3 and urceolus 2 are hung, warded off lead layer 5, bottom 1 is equipped with in bottom, and end lead layer 12 and bottom 11 are equipped with in bottom 1, and upper end 6 is equipped with in upper end; Upper end 6 is provided with exhausr port 8, the vent port 4 that exhausr port 8 and lead layer 5 are established together with, gas port lid 7 exhausr port 8 is equipped with; Be fixed with hanger 9 in the upper end of urceolus 2, bottom is fixed with lower hanger 10, convenient shipment.
Succeeding in developing of this invention, very large contribution has been done in the progress for China's nuclear power technology, facilitates the development of Nuclear Electricity, solves the difficult problem relying on import, has very large economic benefit and social benefit.
