Mitsubishi Cold Fusion LENR Patent Granted Transmutes Nuclear Waste

Amazingly enough LENR patents are now being granted, after passing the muster of the patent examiner. They must perform, as described, in order to do so. Each time I rejoice, and after studying it deeply, appreciate the brilliant and applied efforts undertaken to achieve such a patent granted.

Abstract

The present invention produces nuclide transmutation using a relatively small-scale device. The device that produces nuclide transmutation comprises a structure body that is substantially plate shaped and made of palladium (Pd) or palladium alloy, or another metal that absorbs hydrogen (for example, Ti) or an alloy thereof, and a material that undergoes nuclide transmutation laminated on one surface among the two surfaces of this structure body.

The one surface side of the structure body, for example, is a region in which the pressure of the deuterium is high due to pressure or electrolysis and the like, and the other surface side, for example, is a region in which the pressure of the deuterium is low due to vacuum exhausting and the like, and thereby, a flow of deuterium in the structure body is produced, and nuclide transmutation is carried out by a reaction between the deuterium and the material that undergoes nuclide transmutation.

Now this LENR patent has been granted, Dec. 4th, 2013

Years of consolidated efforts between multiple branches of advanced arts of science has led to improvements, another successful LENR patent is granted. This important LENR technology transmutes nuclear waste to benign elements, with simpler processes than used today, much less expensive machinery, and can even handle those hard to transmute actinides, such as Cs-137.

A Key to How

[0032] According to the nuclide transmutation method described above, the material that undergoes nuclide transmutation is transmuted to a nuclide having a similar isotopic ratio composition, and thereby the nuclide transmutation reaction can be promoted.

Description of Arts Related to Actinides Remediation

[0004] Three types of disposal processing methods are known:

i) disposal processing for actinides and the like by neutron irradiation in a nuclear reactor such as a fast breeder reactor or an actinide burn reactor;

ii) nuclear spallation processing for actinides and the like by neutron irradiation in an accelerator,

iii) and disposal processing of cesium, strontium, and the like by gamma ray irradiation in an accelerator.

Known Processing Methods are Problematic

Hence the growing stockpiles of nuclear waste. Presently utilized nuclear waste disposal processes are clearly inadequate, difficult, and extremely expensive as described here.

[0010] However, in the case of carrying out nuclide transmutation using a nuclear reactor or an accelerator, as in the disposal processes in the above-described examples of conventional technology, there are the problems in that large-scale and high cost apparatuses must be used,

[0011] Furthermore, in the case of processing, for example, Cs-137, which is a long-lived radioactive nuclide fission product, when transmutating Cs-137 radiated from an electron power generator of about one million KW to another nuclide using an accelerator, there are problems in that the necessary power reaches one million KW and a high strength and large current accelerator become necessary, and thus efficiency is low.

[0012] In addition, in contrast to a thermal neutron flux of about 1×1014/cm2/sec in a nuclear reactor such as a light water reactor, the neutron flux necessary for nuclide transmutation of Cs-137, which has a small neutron interaction cross section, is about 1×1017 – 1×1018/cm2/sec, and there is the problem in that the necessary neutron flux cannot be attained.
