Currently, there are many powerful drivers for an increase worldwide in nuclear capacity. Debates for the increase in nuclear capacity are made easier by addressing valid concerns about nuclear fuel cycle safety and proper disposal and or handling of waste material and other by-products of the nuclear cycle. In particular, there is an increased energy supply need in the future, thus, if the concerns in relation to nuclear technology are addressed, this may then permit the widespread safe use of nuclear energy as a preferred choice in the ever increasing energy provision question. Further, the expanding research in fields of nuclear science and the application to nuclear medicine demands an increase in the number of research reactors in countries participating in and intending to benefit from such research.
The growth of the used fuel and radioactive waste treatment market and the storage and disposal market is linked to this demand-driven growth in the number of nuclear power reactors and research reactors planned to meet increasing global demand for energy and nuclear sciences.
However, one of the arguments against the increase of nuclear sites is the generation of radioactive waste, and further, the potential for nuclear disasters such as those witnessed in Chernobyl and Fukushima Daiichi, for example, that have caused significant adverse global impact through their catastrophic failures. Generally, radioactive waste is often just buried in remote radioactive landfills or in countries which have a conscience, medium-term controlled sites, with the hope that the toxic waste will hopefully stabilise over time. However, nuclear waste often remains active for a very long time in a site—over thousands of years with some twenty natural half-lives being necessary before the waste is actually be proven to be stable and safe. Furthermore, effective radioactive waste management is crucial in ensuring that levels of radiation are not causing harm to the environment and to all forms of plant and animal life.
The present invention seeks to provide a method and apparatus for treating radioactive emission which may ameliorate the foregoing shortcomings and disadvantages or which will at least provide a useful alternative.
According to one aspect of the invention, there is provided herein an apparatus and a method for treating a source of radioactive emission.
The apparatus can include at least one reflecting means adapted or configured to be in proximity to the source for receipt of the radioactive emission and to at least partially reflect received emission towards the source, thereby effecting reduction of the radioactive emission from the source.
In one particular example, the reflecting means includes a wire array. In yet a further example, the reflecting means can include a plurality of wire arrays.
According to a further example, the wire of the wire array can include at least one coil of copper wire wrapped around a galvanised metal wire. In yet a further example, the galvanised metal wire is steel wire.
According to another example, the wire array includes spiralled wire formed in circles. It will be appreciated that the circles formed can be continuous, discrete, concentric, or in spirals.
In yet a further example, the wire array includes looped wire formed in zig-zags and or a serpentine formation. It will be appreciated that the wire array/s can include any form and number of wire/s in any combination of pattern, such as one or more spiralled wires, or one or more looped wires, or one or more wires stretched either longitudinally or transversely across other sets of wire/s.
It will be appreciated that the shape of the formation or type of the wire array can affect the type of radiation. Thus for example, circular wire arrays in the horizontal or vertical planes can affect alpha and beta rays, whereas serpentine formation with or without the copper wire can affect gamma rays. Thus, any one or more combinations of shapes/wire formations and types can be used to reflect various types of radiation, as required.
In yet another example, the apparatus includes a plurality of reflecting means. In another example, each of the plurality of reflecting means can include any one or a combination of wire arrays including looped wire formed in circles; and wire arrays including looped wire formed in serpentine or zig-zag arrays. In these examples, each type of wire formation can serve different purposes and types of radioactivity.
According to a further embodiment, the plurality of reflecting means is arranged to at least partially surround the source.
In yet another embodiment, the plurality of reflecting means is arranged within a container, the container being configured to hold the source therein. In yet a further example, the container holds the source at least partially in the centre, and one or more reflecting means are arranged within the container and around the sides of the container, thereby at least partially surrounding the source.
According to yet another example, the container has lead shielding. In yet a further example, the lead shielding is provided outside the container, on all sides of the container. Further, although the container can be of any size or shape, in one particular example, the container is a cube or rectangular prism which can accommodate the reflecting means and the source.
Accordingly, it will be appreciated by persons skilled in the art that the technology described herein can be included in small tea chest sized shapes; medium sized shipping container or single roomed shapes; or even larger warehouses aircraft hangers, and the like.
In yet a further example, the reflecting means is mounted on a panel. In one particular example, for low and intermediate level radiation, the panel or chest can be made from a piece or pieces of plywood and can hold the reflecting means thereon. It will be appreciated that higher level radiation materials may require less combustible substrates however any substrate which is an insulative material may be used to hold the array and it is not limited to wood or plywood.
According to another embodiment, the apparatus includes a plurality of panels, each of a plurality of the panels being placed internally around sides of the container, the source being placed centrally in the container such that the plurality of panels surround the source.
In yet a further example, the reflecting means includes an antenna, the antenna being configured to receive radiation and reflect radiation.
According to another example, the reflecting means includes a horn, the horn being configured to direct reflected radiation back onto the source. In yet a further example, the horn can be of any shape and can extend from one or more wire array/s as required.
In yet another embodiment, the source includes any one or a combination of: uranium; granite and americium. However, it needs to be appreciated that the source can be any matter which emits radiation such as that from historical nuclear test sites, hospital waste, nuclear power plant waste, radioactive water, and the like.
In yet another aspect, there is provided herein an apparatus for treating radioactive emission from a radioactive material, the apparatus including at least one reflecting means adapted to be in proximity to the radioactive material for receipt of the radioactive emission and to at least in whole or partially, reflect received emission towards the radioactive material, thereby stabilising the radioactive material. According to one specific example, the radioactive material is consequentially stabilised in a time frame that is significantly less than the documented natural decay of numerous (twenty or more ˜>2−20) half-lives.
In yet another aspect, there is provided herein a method of treating a source of radioactive emission, the method including disposing/placing/providing at least one reflecting means in proximity to the source, the reflecting means being configured to receive the radioactive emission and to at least partially reflect received emission towards the source, thereby effecting reduction of the radioactive emission from the source.
It will be appreciated that any combination of the features described above or herein is possible and is not limited to the examples provided herein.
The invention may be better understood from the following non-limiting description of a preferred embodiment, in which:
An example of an apparatus for treating radiation emission is shown in
In this example, the apparatus 10 includes at least one reflecting means 25 adapted to be in proximity to the source 15 for receipt of the radioactive emission 20. The reflecting means 25 at least partially reflects the received emission 20 towards the source 15, thereby effecting reduction of the radioactive emission 20 from the source 15.
As shown in the
It will be appreciated by persons skilled in the art that the apparatus 10 can include a plurality or a number of reflecting means 25, including one or more wire arrays 30, which can be formed in a variety of patterns. In the examples shown, the wire array 30 includes a spiralled wire 45, formed in one or more circles 50. In yet a further example, the wire array 30 includes looped wire zig-zagged or serpentine formation 55. It will further be appreciated that the reflecting means 25 can include various combinations of the different wire formations described herein. Accordingly, the apparatus 10 can include a plurality of reflecting means 25, which can be arranged to at least partially surround the source 15. In one particular example, the plurality of reflecting means 25 is arranged within a container 60. In these examples, the container 60 is configured to hold the source 15 therein. In a further example, which is further described below, the container 60 can have lead shielding, which is configured to form a barrier between the radioactive source 50 and the outside of the container 60.
According to a further example, one or more reflecting means 25 can be mounted on a panel 65. Thus, the apparatus 10 can include a plurality of panels 65, which are then each placed internally around the sides of the container 60, and the source 15 is then placed in the middle of the container 60, such that the plurality of panels 65 then surround the source 15.
It will be appreciated by persons skilled in the art that the reflecting means 25 can include one or more wire formations, which can include one or more antennas. In this particular example, the or each antenna is configured to receive radiation and reflect radiation. As further discussed below, the antenna can include a horn 80, where the horn 80 is configured to direct reflected radiation back onto the source 15.
In yet a further example, it will be appreciated by persons skilled in the art that the source can include any one or a combination of uranium, graphite, or any material which emits radiation, including property, an area or volume affected by radiation and living creatures such as mammals.
It will be appreciated by a person skilled in the art that the panel 65 can be any dimension. In the example shown in
Further, in the examples of
It will be appreciated by persons skilled in the art that the examples shown in
According to one specific example, the present method and apparatus was tested with a test sample of uranium ore, (which was placed in a container resembling a tea-chest (as shown in
In the aforementioned uranium ore example, the test sample was placed in the middle of the tea-chest sized cabinet, and was surrounded by a number of gamma radiation reflecting means on all sides of the body of the chest. The sample and the various reflecting means were then covered by one or more covers, and the lid of the chest was then closed. The chest was also covered in lead cladding, for occupational health and safety reasons, and to minimise any known external interference and internal radiation leaking to the outside. However, it will be appreciated that covering in lead is optional. In this example, a measuring device being a Geiger Counter was used to measure the ionising radiation being emitted. The measuring device used was an S.E. International Inc. Radiation Alert® Inspector, which is a handheld digital radiation survey meter.
Measurements were then taken by opening the ‘tea chest’ and reading the sample on a daily basis, once per day as close as possible to the same time of day.
It was observed that the radioactive emission from the sample proceeded towards stability, as shown in
Similarly to Example 1, above, further testing was conducted on granite as the source which emits radiation. The apparatus used was the same as that for Example 1.
The exposure of granite to the reflecting means reduced the radiation emitted from the granite. As shown in
Examples 1 & 2 are but a few examples of alpha beta gamma and neutron (or combinations thereof) as several other materials and tests were also carried out, however do not in any way materially affect the terms of this patent and should it be required, will at such time as necessary be the topic and discussion elsewhere if and as required.
According to one particular example, one or more horns 80 can be provided extending from the first type of wire formation 70. In the example shown in
It is hypothesised that in this type of structure, one of the wire arrays (such as the first type of wire formation 70) works to reflect back alpha and beta particles of radiation, whereas the second type of wire formation 72 works to reflect gamma radiation. It is further hypothesised that it is the two wire types of wire formations working together that effect decrease in radioactivity and (and hence increase in stability of the source), as shown in
It is hypothesised that as these two types of metallic material effectively acting as an antenna are directionally placed at 90 degrees to each other, they enhance stabilisation of radiation from the source 15. Additionally, it is hypothesised that the reflecting means 25 is able to change unstable clockwise movement of atomic matter into stable anticlockwise movement. That is, the antenna receives atomic matter having anti-clockwise movement and reflects it so as to have clockwise movement, thus forcing the atomic matter to stabilise.
It will be appreciated that there can be a number of panels 65 with reflecting means 25 disposed around, and in proximity to the source 15. The placement of the panels 65 can be such that there are a plurality of panels 65 on either side of the source 15. The panels 65 can be overlapping, and/or placed in various directions to each other.
Further to this, it will also be appreciated that on each panel 65 there can be a variety of different shaped reflecting means 25, not limited to the examples described herein. That is, the wire arrays 30 on each panel 65 can be of a different form and it is not necessary that all the panels 65 be identical, nor the wire arrays 30.
It will also be appreciated that the examples shown herein are examples of a container 60 only and that many other devices or forms of surrounding the source with reflecting means 25 may be possible.
It will be appreciated that the example shown in
It has been found that the present apparatus and method can reduce or even can negate ionising radiation, thereby stabilising radioactive material. In particular, it is believed that the four-layer unicursal labyrinth antenna system, with the transverse copper overlay, such as the example shown in
It is further hypothesised that the overlapping concentric wire array system described herein can generate a Vescial Pisces Interference Pattern resulting in a re-stabilisation of proton baryonic core. Unstable baryonic cores can demonstrate opposite spin by comparison with the more stable, proton baryonic cores. In effect, this system recovers the memory component of the proton structure, re-establishing coherence. Accordingly, it is hypothesised that this affects alpha particle radiation—especially if used with three or more layers×12 concentric steel 2 mm wire cores wound with 0.75 mm ceramic coated copper wire spiral with a 50% overlap.
It is also hypothesised that beta particle radiation can be affected with 3 layer×12 concentric steel 2 mm wire core with 0.75 mm ceramic coated copper wire spiral with 50% overlap, and a further alignment at 90 degrees to alpha particle componentry. The beta particles exhibit opposite spin to stable electrons due to weak meson core bonding. Being particulate in character, they also respond to re-patterning as occurs in alpha particle component effect.
In yet a further hypotheses, neutron radiation can be affected by three overlapping (by 50%) 2 mm steel wire spirals generating interference pattern overlaid by transverse copper grid generating a second interference pattern. It is hypothesised that neutron binary baryonic core has 4 bonds binding the neutron together, while unstable neutrons have only 2 bonds per baryon pair. Stable neutrons also exhibit anticlockwise spin whilst unstable neutrons have negligible or no spin component. This dual interference pattern resets the stable neutron pattern.
It will be appreciated that the method and apparatus discussed herein can be used in or as a part of a nuclear fuel cycle radioactive waste treatment system, including and not limited to nuclear waste contamination remediation industries, and the like.
It will be further appreciated that the method and apparatus discussed herein can be implemented in relatively quick time frames and inexpensive manner.
Further, the method and apparatus discussed herein can be used on any type or form of radiation source including radioactive material used in nuclear energy or power stations, in medical applications, research and development, mining applications, as well as military and weapon manufacturing and decommissioning industries. The method and apparatus discussed herein can also be applied to contaminated sites such as bodies of water, holding repositories of heavy water, both large and small buildings, and the like.
It may also be possible to use the method and apparatus discussed herein on animals, including humans who have been exposed to radiation, to assist in stabilising the radiation being emitted. For example, the method and apparatus described herein can assist in accelerating recovery from exposure to radioactive sources caused by medical radiation treatments such as X-rays, and dyes, or caused by ingestion or inhalation of, or contact with radioactive dusts, liquids, or gases from contaminated radioactively hazardous areas such as depleted uranium explosion sites and nuclear accident sites. Treatment by the method and apparatus as described herein can restore stability of any residual radioactivity of radioactive solids, liquids, or gases on or within the body.
Further, it may also be possible that with effective treating of a radiation source, such as treatment of radiation waste that is buried, and thereby stabilising the waste, the waste which has been stabilised can be reused in future applications.
The method and apparatus described herein can be installed or retrofitted for the treatment of either dry waste or pooled waste at existing nuclear power reactors, research reactors and waste treatment and processing facilities, providing an integrated capability to quickly process spent fuels and waste avoiding the current ‘on-costs’ of handling, transport, packaging and long-term storage.
The method and apparatus described herein can be integrated into the construction of nuclear power reactors, research reactors and waste treatment and processing facilities.
Further, the system and method described herein can be used in large-scale radiation contamination such as those caused by the Chernobyl and Fukushima Daiichi that have caused significant adverse global impact through their catastrophic failures. Further use can include the treatment of any decommissioned nuclear facility.
Accordingly, the advantages which can be achieved by embodiments of the apparatus and method described herein include, however are not limited to:
It will further be appreciated that although the present description has been made in relation to radiation, the present application may also have applications with respect to electromagnetic waves generally. Thus, the apparatus 10 may be able to reflect any type of electromagnetic wave and diffuse its effect on it's surrounding environment.
Those skilled in the art will appreciate that the invention described herein is susceptible to variations and modifications other than those specifically described. All such variations and modifications are to be considered within the scope and spirit of the present invention the nature of which is to be determined from the foregoing description.
It will be appreciated that any form of the word “comprising”, “comprises”, “comprised”, and the like, as used herein, is used in an inclusive manner and is not excluding or limiting in its nature or meaning.
