A feasibility of rapid setting cement (RSC) as an agent of immobilization for certain elements such as fission products or radioactive materials was explored. Cerium (Ce) and cesium (Cs) have been selected as a surrogate for U and/or Pu and fission products, respectively, in this study in three phases. In Phase I, RSC was evaluated for physical properties (e.g., porosity, density, pH values ...
These fibers are added to the concrete mix and account for 20 to 25 percent of the end product. The fibers vary from polyester to fiberglass bars, basalt, steel, and stainless steel. Each of these integrated fibers create a progressively stronger end product, with steel and stainless steel delivering the greatest gains in strength.

The chemical forms of important fission products (FPs) in the primary circuit are essential to the source term analysis of high-temperature gas-cooled reactors because the volatility, transfer, and diffusion of these radionuclides are significantly influenced by their chemical forms. Through chemical reactions with gaseous impurities in the primary circuit, these FPs exist in diverse chemical ...
Cesium-137 (137 Cs), a major by-product of nuclear fission, is a medium half-life (30.2 years ) radionuclide of special concern from a radiological safety point of view because of its high mobility in the environment and its decay to a metastable gamma emitter.
It simply involves the addition of cement or a cement-based mixture, which thereby limits the solubility or mobility of the waste constituents. ... of contaminated material. The end product resulting from the solidification process is a monolithic block of waste with high structural integrity. ... (e.g., cesium, strontium, and cobalt) and toxic ...
The aim of the present study is to investigate the possibility of solidifying exhausted synthetic zeolite A, loaded with (137)Cs and/or (90)Sr radionuclides, in Ordinary Portland Cement (OPC). Several factors affecting the characteristics of the final solidified waste product towards safe disposal such as mechanical strength and leaching ...

12%Radioactive cesium found in municipal solid waste incineration (MSWI) fly ash can be easily eluted through contact with environmentally sourced water, such as rainwater. Dissolution suppression treatment of radioactive cesium, such as through cement solidification or geopolymer solidification, has been previously studied. Treatment through …
cesium from concrete. The objective of this evaluation was to quantify the effect of residence time of radiological contamination, such as would result from an urban "dirty bomb", on concrete relative to decontamination efficacy of various decontamination technologies. The technologies chosen for the evaluation were selected from among the
Overall between 5 and 59% of cesium was adsorbed on cement mortar at equilibrium. The quantities of adsorbed Cs at equilibrium ranged from 0.0395 to 22.34 μg cesium/cm 2 of coupon surface. At the same time, the equilibrium concentration in solution ranged from 0.0069 mg L …

Cesium-137 . An inevitable byproduct of nuclear fission is the production of fission products which are highly radioactive. Cesium-137 and strontium-90 are the most dangerous radioisotopes to the environment in terms of their long-term effects. Their intermediate half-lives of about 30 years suggests that they are not only highly radioactive but that they have a long enough halflife to be ...
The leaching rate of cesium has been studied in cement. The solidification matrix was a standard Portland cement with increased sulphate resisting properties mixed with 300 kg/m3 or 350 kg/m3 powdered ion exchange resins, and with or without 5 weight-% zeolite added to the grout. The leaching rates from an ordinary cement matrix and a cement matrix mixed with zeolite were measured to be …
