Experiment on the Absorbtion of Long-Lived Radionuclides

Introduction Long-lived radioactive nuclides in radioactive waste are serious pollutants that travel through groundwater, and geological substances affect their adsorption. The presence of radionuclides and toxic metals in waste is a major environmental problem. Paper candesium (iv) water pollutants such as arsenic, antimony, cadmium, cobalt, copper, chromium, rare earth elements (REE) have become a problem for the past few years. Many important elements of REE The field and the nuclear fuel cycle (NFC), the analysis of these elements and the widespread application of separation technology are attracting attention by technology

Selective separation based on the DIAMEX-SANEX process optimizes long-lived radionuclides (focusing on the separation of Am and Cm) for recycling in the IV generation fast neutron reactor where uranium is used as blanket fuel did. This option can also be combined with the COEX and DIAMEX-SANEX processes. All three processes are evaluated during the development process and one or more processes are selected for industrial scale development to build a pilot plant. In the long run, the goal is to recover the entire uranium, plutonium, and subactuator elements. In fact, one technology - promising GANEX or similar technology - needs to be verified in the 4th generation fast reactor industrial development around 2040, at that time the current La Hague factory needs to be replaced There will be.

Larsen explained that long-lived cosmogenic radionuclides are formed when the cosmic ray that continues to collide with the earth is crushed to oxygen atoms to produce a rare isotope called 铍 10 (10 Be). "In regions where erosion is occurring rapidly, there are few 10 Be due to it being lost, but in slowly eroded areas the soil accumulates more 10 Be." Of these, each 10 Be atom Can be measured. These concentrations are used to quantify annual soil erosion depths before Midwest agriculture.
