Definitions
- the invention relates generally to feedthroughs for passing electrical signals or currents through walls of hermetically sealed environments.
- the invention relates to feedthroughs suitable for radioactive environments such as nuclear reactors.
- Bushings for supplying or removing electrical signals and supply currents in hermetically sealed containers are known, for example, from DE 102009011 277 A1, DE 102009 014334 A1 and DE 102010 055 177 A1.
- the challenge is not only to hermetically seal the interior of the reactor, but also to shield the emerging radiation that penetrates in the case of gamma radiation. It is known to attach shields to the cable boxes in which the field cables are connected to the bushing.
- a bushing with cable boxes for use on a reactor containment is described, for example, in the above-mentioned DE 102010 055 177 A1.
- the invention is therefore based on the object of providing safe, hermetically sealed electrical leads through reactor or
- a bushing in particular a cable bushing, is provided for shielding against penetrating radioactive radiation
- a metallic tubular housing the ends of which are each provided with a closure, so that a hermetically sealed interior is formed in the tubular housing between the closures, the closures each having at least one insulating body through which at least one electrical lead-through conductor is passed, so that the leadthrough conductor is fixed electrically insulated from the tubular housing in the respective closure, and wherein
- At least one connecting conductor running in the interior is provided, which connects an electrical lead-through conductor on one of the closures with an electrical lead-through conductor on the other closure, wherein
- From the shield body are arranged, which are each perforated with at least one opening, wherein a connecting conductor is passed through the opening.
- this arrangement can limit the radiation emerging from the cable bushing on the outside of a reactor containment to a specified value.
- shielding bodies that are adjacent in the axial direction are constructed from mutually different materials. Different shielding bodies do not have to be installed in each case. For example, two similar shielding bodies can be joined together, which are then followed in the axial direction by a shielding body made of a different material, which then also has a different type of shielding effect.
- a neutron moderator is particularly suitable in combination with a further shielding body which has a material with a high effective cross section for the capture of thermal neutrons.
- at least one of the shielding bodies has a neutron-capturing material with an element with a capture cross-section for thermal neutrons of greater than 10 barns and an ordinal number of at least 5, preferably greater than 5.
- the neutron-capturing materials used are preferably those which contain at least one of the elements, cadmium, tungsten, silver or a rare earth.
- Cadmium is particularly preferred. This element has a high effective cross-section and is comparatively inexpensive. Cadmium is a poisonous heavy metal, but due to the hermetic enclosure in the cavity of the bushing, this does not mean any serious disadvantage.
- At least one shielding body with a gamma absorber is provided, in particular containing an element with an ordinal number greater than 30.
- Particularly preferred materials are tungsten and lead. Tungsten shields a little better than lead, is mechanically very stable and has a high melting point. In contrast, lead is considerably cheaper. If metallic cadmium is also used for a shielding body, the advantage of the high melting point of tungsten cannot be used, since cadmium also has a low melting point. Lead is therefore preferred as a component of a gamma absorber.
- the bushing is designed as a high-temperature bushing, for example for use in the reactor pressure vessel.
- the device contains high-melting metal hydrides as a shielding body for neutron moderation instead of plastics such as polyethylenes, polyetheretherketones or polyimides.
- the rare earth hydrides and zirconium hydride in particular have proven to be advantageous.
- the leadthrough can contain high-melting, inorganic boron compounds such as, for example, boron nitride, boron carbide in pure form or as a constituent of boron aluminum alloys (Boral) as neutron absorbers.
- cadmium in particular can be used as Neutron absorbers replaced and thus the implementation can also be used in environments with temperatures above the melting point of cadmium.
- materials whose melting point for the ambient temperature of a high-temperature application such as lead, is replaced by pure tungsten or as a component of high-melting alloys, in order to shield the gamma radiation.
- the use of tungsten is particularly advantageous here, since tungsten has a high melting point of 3422 ° C. in addition to a good absorption cross section.
- the implementation according to this development can also be used, for example, in areas with high operating temperatures, for example in the primary circuit, in particular of so-called small modular reactors.
- the opening in the shielding body is arranged at a distance from the inner wall of the tubular housing, so that the connecting conductor is held at a distance from the inner wall.
- the openings of the individual shielding bodies are offset from one another.
- the openings in successive shielding bodies can be rotated relative to one another and / or displaced in relation to one another in at least one plane.
- the hole pattern formed by this arrangement of the openings with respect to one another ensures that radioactive radiation does not pass through the passage in the area of the openings without having to penetrate at least one shielding plate.
- Fig. 1 shows a cross-sectional view of a bushing.
- FIGS. 2 to 5 show embodiments of closures in FIG.
- Fig. 6 shows a container for holding radioactive material with a
- Fig. 1 shows a bushing, here a cable bushing 1 in cross-sectional view.
- the cable bushing 1 of this example is designed so that particularly good shielding against penetrating radioactive radiation of a reactor is achieved if the end 31 shown on the left in the illustration protrudes into the reactor or reactor containment, or provides the electrical connections on the inside. At the opposite end 32, the outside lines are connected.
- the aim is to achieve extensive shielding despite the compact design.
- neutrons and gamma radiation are relevant for penetrating radiation from the reactor.
- the cable bushing 1 for shielding against penetrating radioactive radiation has a metallic tubular housing 3.
- the housing 3 can be welded directly to the reactor or reactor safety container wall for hermetic sealing. In general, it is therefore preferred to use a material for the housing 3 which can be easily welded. Steel, in particular, is suitable for this purpose, which is particularly suitable for a reactor or reactor containment vessel made of steel.
- the ends 31, 32 of the tubular housing are sealed with closures 5, 6.
- a hermetically sealed interior 8 is thus formed in the tubular housing 3 between the closures 5, 6.
- this is advantageous in order to include any gaseous radioactive reaction products.
- the double hermetic seal prevents radioactive substances from escaping even if the bushing fails on one side.
- the closures 5, 6 each have at least one insulating body 7, 9 through which at least one electrical lead-through conductor 10 is passed so that the lead-through conductor 10 is fixed in the respective closure 5, 6 in an electrically insulated manner from the tubular housing 3.
- at least one of the insulating bodies 7, 9 is an element made of glass, glass ceramic or ceramic. Both insulating bodies 7, 9 are preferably formed by elements made of glass, glass ceramic or ceramic. These elements are good electrical insulation materials and can be produced in a simple manner by melting or brazing in the case of ceramic in the respective closure. Typically, a one-to-one assignment is carried out with the lead-through conductors 10.
- the bushing can also have sensors and / or actuators that are connected via one or more bushing conductors 10.
- a gamma ray sensor 21 can be provided, which is read out via one or more feed-through conductors. This can be used, for example, to measure the neutron flux in the bushing via the gamma radiation emitted by a neutron absorbing material.
- the closures 5, 6 can be connected to the tubular housing 3 with circumferential weld seams 12, as shown. As shown, the closures can be in the form of short pipe sections or flanges. 2 schematically shows a perspective view of a closure 5, 6.
- the closure 5, 6 comprises a metal body 50 which, as mentioned, can have the shape of a flange or a pipe section.
- the metal body 50 has at least one opening 52 in which the insulating body 7 or 9 with the lead-through conductors 10 held therein is arranged.
- the insulating body 7, 9 can be formed from glass, glass ceramic or ceramic. This can then be produced by melting down glass or glass ceramic or brazing ceramic in the opening 52. During the melting or brazing, the leadthrough conductors 10 are held in their intended positions and, after cooling, are fixed in an electrically insulated manner in the glass, the glass ceramic or the ceramic.
- FIG. 3 shows an embodiment of a closure 5, 6 in plan view
- FIG. 4 shows a sectional view of the closure 5, 6.
- the closure according to FIGS. 3 and 4 has several insulating bodies 7, and 9 respectively.
- several openings 52 are also provided, in which the insulating bodies 7, 9 are fixed in a sealing manner.
- at least one of the closures 5, 6 of the bushings has a plurality of insulating bodies 7, 9 through which at least one bushing conductor 10 is passed.
- 5 shows a variant of the examples described above.
- This variant is based on the fact that at least one of the closures 5, 6 has several openings 52 which are closed with insulating bodies 7 and 9, at least one lead-through conductor 10 being fixed in at least one of the insulating bodies 7, 9.
- three insulating bodies 7, 9 are provided, through each of which three lead-through conductors 10 are passed.
- the embodiments with a plurality of openings 52, as the examples in FIGS. 3 to 5 are based on, generally have the advantage of a higher pressure resistance compared to the embodiment with a single insulating body.
- the packing density of the leadthrough conductors 10 is limited.
- At least one connecting conductor 13 running in the interior space 8 is provided, which connects an electrical bushing conductor 10 on one of the closures 5 to an electrical bushing conductor 10 on the other closure 6.
- shielding bodies 15 are arranged one behind the other in the axial direction of the tubular housing 3, each of which is perforated with at least one opening 17, a connecting conductor 13 being passed through the opening 17.
- the opening 17 or the plurality of openings is arranged at a distance from the inner wall 33 of the tubular housing 3, so that the connecting conductor 13 is kept at a distance from the inner wall 33.
- the connecting conductors 13 can generally be surrounded by an insulating sheath, for example a silicone sheath. This also provides insulation from metallic shielding bodies, such as those made of tungsten or lead.
- the shielding bodies 15 are made from special absorber materials.
- at least one shielding body 15 with a gamma absorber is provided. This contains an element with an atomic number greater than 30.
- tungsten and lead as metals with a very high density, have proven to be extremely efficient, the former being very expensive and only slightly better shielding than lead.
- two stacks 150 of shielding bodies 15 are provided, in which the two shielding bodies facing away from the end 31 are gamma absorbers 16.
- these gamma absorbers can be made of tungsten or lead, or contain at least one of these materials.
- At least one of the shielding bodies 15 has a neutron moderator 19 in the form of a hydrogen-containing material, in particular a plastic such as PE, PI or PEEK.
- At least one PEEK plastic containing shielding body 15 is provided for this purpose. Since the plastics PI and PEEK contain many hydrogen atoms, they act as a neutron moderator and also fulfill their function as an electrical insulator. In addition, PI and PEEK have one of the highest melting points among high-performance plastics, which is more than twice as high as that of PE. With a sufficient layer thickness, all fast neutrons are decelerated to thermal neutrons and can be captured by a neutron absorber.
- At least one of the shielding bodies 15 has a neutron-trapping material with an element with a trapping cross-section for thermal neutrons of greater than 10 barn and an atomic number greater than 5.
- thermal neutrons are suitable under other materials such as boron (as an alloy with aluminum: Boral) or cadmium. Boron has the decisive disadvantage that for every thermal neutron absorbed, one boron atom breaks down into lithium and helium. In this case, over time in a hermetically sealed system, as represented by the present implementation, a considerable pressure can build up due to the helium gas formed, as is the case, for example, in moderator rods in nuclear reactors.
- neutron-capturing materials are also those with at least one element selected from the group of rare earths, tungsten, and silver.
- gamma radiation is also generated, which is then absorbed by a shielding body 15 in the form of a gamma absorber, in particular by tungsten or lead shielding plates. Since the melting point of cadmium at 321 ° C is still below that of lead (327 ° C), the property of the high melting point of tungsten (3422 ° C) cannot be used when using cadmium. Lead is also much cheaper. Lead as a gamma absorber is therefore particularly preferred when using metallic cadmium as a neutron absorber.
- the degree of shielding can be controlled over a wide range via the layer thicknesses of the various absorber materials and the number of absorber bodies. With a design as shown in FIG. 1, the radiation from the container can be shielded essentially completely.
- the problem can arise that the gamma radiation acting on it leads to a change in the material over time.
- the preferred PEEK as well as PI plastic for the neutron moderator (s) 19 is characterized by a particularly high resistance to gamma rays.
- a further development of the invention provides that the bushing is filled with an inert gas, for example nitrogen. Alternatively, the bushing can be evacuated. Both measures lead to a reduction in the number of ionizable particles in the implementation.
- the radiation-induced ok is characterized by a particularly high resistance to gamma rays.
- Aging of the plastic can be reduced or at least slowed down, thus increasing the service life of the implementation.
- a degeneration of the neutron moderator can at least be slowed down by providing, without limitation to the example shown, according to a preferred embodiment that two shielding bodies are provided, one of which comprises a neutron moderator 19 and another a shielding body 15 with a neutron catcher Material 18 is provided.
- a gap 22 can generally be provided between the shielding bodies 15 with neutron moderator 19 and neutron-capturing material 18, as is also shown in the example shown.
- This intermediate space 22 can optionally, unlike in the example shown, also be completely or partially filled with a gamma absorber 16 or a corresponding shielding body 15.
- At least three shielding bodies 15 are provided, with a shielding body 15 with a neutron-capturing material 18 and after the shielding body in one direction after a shielding body 15 with a neutron moderator 19 15 with a neutron-capturing material 18 from a shielding body 15 with a gamma absorber 16 in the tubular housing 3 are arranged.
- the cable bushing 1 is then installed in a container in particular in such a way that the above-mentioned direction along the tubular housing 3 points outwards from the container interior. In this way, the neutrons are first slowed down, then captured.
- both the gamma radiation originating directly from the inside of the container and the gamma radiation generated during neutron capture in the bushing itself can then be captured by the gamma absorber.
- this sequence of shielding bodies can also be repeated at least once.
- an insulating end plate 25 is placed on at least one of the insulating bodies 7, 9 on the outside. These end plates 25 serve, among other things, to support the lead-through conductors 10 laterally. This can be useful, for example, when tensile forces are exerted on the cables connected externally to the lead-through conductors 10.
- the leadthrough conductors 10 can protrude from openings in the end plate 25.
- the lead-through conductors within the end plate 25, which consists of an electrically insulating plastic, end in channels present therein and are then also connected with cables inside the end plate in the channels.
- a plastic in particular PEEK or PI, is also preferably used for the end plate 25.
- a body made of boral or generally a material containing boron can also be added to the outside as a neutron moderator, since the creation of helium gas does not lead to a pressure build-up in the bushing here.
- cable boxes or plug connectors 31 can be provided in order to hold the supplied cables.
- the cable boxes or connectors 31 can be kept compact compared to known bushings, since the task of absorbing radioactive radiation, which otherwise occurs through materials in the cable box or connector, is already implemented by the shielding body 15 from inside the implementation.
- shielding materials can also be accommodated in the cable boxes or plug connectors 31, provided that space is available for this.
- the tubular housing 3 is preferably made of high-strength steel that is easy to weld.
- 6 shows schematically an example of a container 2 with a cable bushing 1 according to a further aspect of this disclosure.
- the cable bushing 1 produces one or more electrical connections from the environment into the interior 35 of the container.
- the container 2 is designed to contain or receive radioactive material 20.
- the container 2 can for example be designed as a steel or reinforced concrete shell.
- a tube 27 can be welded or cast into the container wall 2, as shown. The bushing 1 can then be pushed into the pipe 27 and sealed with the pipe 27 with a circumferential weld seam 29 be welded.
- the cable bushing 1 can also be welded directly to the edge of an opening in the container 2. In addition to welding, other connection methods, such as screwing, may also be considered. This also applies to the connection of the closures 5, 6 to the tubular housing 3 of the bushing 1.
- the container 2 is in particular a reactor or reactor containment of a nuclear reactor.
- the radioactive material 20 in this case then comprises the fuel of the nuclear reactor or the reactor itself if the container 2 represents the reactor containment.
- other containers 2 for radioactive material can also be used. Because of the compact
- the cable bushing 1 is also suitable for transport containers, for example to transport fuel rods.
- the cable bushing can have a specific sequence of shielding bodies 15 in order to attenuate the radiation emanating from the material 20 in the interior 35.
- the cable bushing has a neutron moderator 19 in the outward direction from the interior 35, then a neutron-capturing material 18 and, behind it, a gamma absorber 16.
- the cable bushing 1 is generally also suitable for use in encapsulated systems in which radioactive material is processed, for example in systems for producing fuel rods or processing radioactive waste.
