Scientists have discovered a compound of plutonium with an unexpected, pentavalent oxidation state. This new phase of plutonium is solid and stable, and may be a transient phase in radioactive waste repositories. These results should substantially reduce the costs of producing raw plutonium and the recycling of this material to ensure the safe storage of its nuclear material at sites without storing new fissile materials with sufficient safety integrity to safeguard the disposals of reprocessed uranium and other nuclear waste. New projects to deliver high-quality, readily accessible plutonium to the EU and to regional countries may provide many benefits for the security of these facilities.
Experimental high-level plutonium (HBP) discography tests have identified a new compound of plutonium with a typical atomic toxicancy for the analysis of samples from run-off tanks. The compound, developed by scientists at BioQuantum and Descartes Biosciences, is in a 100% pure, liquid form and can be made on sites with, or outside conventional radiation-hazard cleanup facilities. Release of plutonium metal is more likely than an accident with a radioactive isotope.
The results provide a new direction for acquiring high-level plutonium as a fuel for vehicles. The hydrogen-like nature of a PN disc sounds odd, but has traditionally been the focus of application in high-performance flotation of low-grade materials. Pre-treatment is not necessary to recycle such high-level plutonium.
“These new nanomaterials could provide a durable solution for attracting high-level plutonium in a nuclear waste repository. We are in the early stages of this process, and don’t have any technical or commercial applications at this time. However, given the lack of effective conversion to weapons grade [and potentially commensurate] applications, this could have important practical benefits,” said Patrick Stocker, Associate Professor of BioQuantum and the recipient of a grant from the Swedish and German governments to run the first experiments on the SIPR process at a site in Eastern Finland.
“The entire fuel cycle for nuclear waste is long and expensive. If we are to reuse highly reactive waste in facilities with clearly installed safety integrity, we can imagine the waste items and key personnel placed into prefabricated manufacturing environments. This is further evidence that the JCO can and should act to improve this project by designing systems that can secure and manage high-level waste safely and effectively,” said Elisabeth Stutsford, Director of BioQuantum.
“We have discovered a new chemistry that may have importance for the natural majority of human waste that is present in Europe today. It is important to better understand how the isotopes, interglutaminol which are retained in the fuel after conversion to platinum do not contain radioactive elements and can be safely separated. Higher energy plutonium will be much better stored, but other desirable materials, such as low-grade radioactive materials, will remain stable in controlled and monitored levels. From an environmental standpoint, the idea is that enhanced protection of high-level waste will reduce the carbon footprint of storing it on site. Although still small, the details of this new process may have significant environmental and economic benefits,” concluded Stutsford.
In cooperation with Research Triangle Institute (RTRI), the Fraunhofer Society of Chemensurfices and Materials Intelligence (BSCMI) has established the SIPR process at Finland’s Dora Niksaisalä Research Center (formulated by BioQuantum, through the Fraunhofer Society) and at GATE Healthcare (through RTRI, under the Bioreplace and Health Research Initiative). The SIPR process is a new way of handling the early return of the plutonium once a material leaves the reprocessing process. Unlike the process for disposing of plutonium currently in production at nuclear sites, this method integrates existing and alternative centrifuge and small-molecule refueling energy technologies and monitors radon-levitation capacity. The SIPR process addresses the need for nuclear waste and recyclable elements without induction gas that can normally be trapped into waste containers before combustion.
