Definitions
- the invention relates to a device for shielding a fluid wall bushing against high-energy electromagnetic Radiation, nuclear radiation or corpuscular radiation.
- the after-treatment of spent fuel elements nuclear power plants happen among other things in so-called "hot cells", i.e. in sections of nuclear facilities that are against outside neutron and gamma radiation shielded are. Such hot cells are usually located Machines for the aftertreatment of the fuel elements and lighting devices. The generated in the hot cells Heat and the residual heat of the spent fuel elements must be through appropriate ventilation wall bushings be discharged to the outside.
- hot cells i.e. in sections of nuclear facilities that are against outside neutron and gamma radiation shielded are.
- Such hot cells are usually located Machines for the aftertreatment of the fuel elements and lighting devices.
- the generated in the hot cells Heat and the residual heat of the spent fuel elements must be through appropriate ventilation wall bushings be discharged to the outside.
- the walls of the hot cell typically have one Thickness of 150 cm and consist of concrete or reinforced concrete.
- the Systems for ventilation of the hot cells are typically located outside the hot cells themselves.
- the implementation has also been straight and led through the walls without kinks.
- the implementations typically have a diameter of 50 to 75 cm.
- the shielding screws are made of iron and have several turns over the length of the feedthrough. This enables them to absorb gamma radiation.
- a rough measure of the absorption cross section for gamma radiation is the density of the material used for shielding.
- the concrete used has a density in the range of 2.35 g / cm 3 . If iron with a density of about 7.8 g / cm 3 is used, the screw flights must fill about a third of the space for the passage. The thickness of the screw threads and the pitch or the number of turns in the bushing are selected accordingly.
- Such iron screws are not suitable, however, Absorb neutron radiation.
- spent fuel treatment always occurs a mixed radiation of gamma and neutron radiation on.
- the neutrons are high-energy. So that Neutron radiation can be effectively absorbed the neutrons are slowed down first. This process is also called moderation or thermalization of Called neutrons.
- Hydrogen is particularly suitable for this.
- Polyethylene has proven to be a very hydrogen-containing solid (PE) proven for neutron moderation. Also borated PE or graphite are suitable.
- the PE blocks take up a lot of additional space. Further the iron screws weigh up to 2 tons. Corresponding their manufacture, transport and assembly are complex.
- the object of the invention is the shielding device of the type mentioned in terms of their space requirements and to improve their manufacture and assembly.
- the generic device characterized by a plurality of disk-shaped Shielding elements in the fluid wall bushing are spatially arranged in such a way that they collect the radiation, while the wall duct is permeable to the fluid remains; wherein each shielding element is at least one the radiation to be selected individually for each shielding element has absorbent material and wherein number and Shape of the shielding elements are chosen so that there is a desired Shielding characteristic for the radiation in the Wall penetration results.
- the shielding device according to the invention is modular individual shielding elements. So you can different parts made in a simple way transported and installed and also at a later date can be easily changed.
- the material of the individual shielding elements can be the requirements of the desired shielding characteristic to get voted.
- individual shielding elements will be used Materials form the individual components of the radiation absorb optimally. From the common arrangement of the different Shielding elements then total desired shielding characteristics.
- the individual shielding elements can in turn be made of different materials be composed. Combinations of both types of Shielding elements are equally possible. So it can any combination of those suitable for absorption Materials are used. That way you can the costs for the shielding materials and thus for the Shielding device can be optimized.
- An arrangement of the individual shielding elements can, for example consist in that in the form of panels trained shielding elements offset one behind the other are.
- the disk-shaped shielding elements as perpendicular to the axis Screw segments formed.
- the screw segments point a uniform shape and are each given a predetermined Staggered angles along their axis arranged one behind the other in the wall bushing. As a result this results in a helical shielding device.
- a shielding device the shape of which is thus obtained that comes very close to the iron screws.
- the pitch of individual screw segments Shield screw can be changed.
- fluid throughput and shielding be optimally coordinated.
- the Uniform screw segments are manufacturing technology particularly cheap.
- the ventilation ducts are approximately 150 cm thick reinforced concrete walls of the hot cells. They have a diameter of 50 to 75 cm and run straightforward.
- the one Wall bushing 1 has arranged shielding device overall a helical shape. This minimizes the Flow resistance for the air flowing through.
- the shielding device is made of individual disc-shaped shielding elements 2 and 3, which is the shape of Have screw segments.
- the shielding elements 2 exist made of iron to absorb gamma radiation and the shielding elements 3 made of polyethylene (PE) to thermalize neutrons and absorb.
- PE polyethylene
- the individual shielding elements 2 and 3 are on one central axis 4 of the wall bushing arranged one behind the other.
- 2 to 4 are examples of possible shapes of the screw segments shown.
- the shape of the screw segments is in no way based on the examples shown according to the 2 to 4 limited.
- the screw segments always have a central hub 5, so that they are placed centrally on axis 4 can.
- screw segments are based on ensure a sufficient shielding effect.
- the shielding elements are made of more absorbent Material made, so their area can be correspondingly smaller chosen and thus the flow resistance for the air due of the larger free cross section can be reduced.
- the number of turns that the helical shielding device has should have, however, is thereby limited below that even under a very unfavorable, oblique angle through the wall duct 1 running gamma quantum or neutron mandatory adequate shielding must experience. Furthermore, the shielding characteristic must be above the Cross section of bushing 1 be even.
- the shielding elements are chamfered at their edges, so that the shielding device is overall a smooth, step-free Has surface.
- the mass of the Screw stay the same to avoid the shielding effect Reduce.
- the individual Screw segments on one side with a projection and on their other side with a complementary recess be provided.
- Projection and recess are like this arranged that when the screw segments are placed one behind the other and inserting the projections into the recesses the given angular misalignment of neighboring screw segments between the individual screw segments. A later one Then change the screw pitch more difficult.
- the assembly of the shielding device can, as with a cast snail, done at the factory. It is more advantageous to assemble the device on site, if necessary directly inside the wall bushing.
