The effects of gamma radiolysis on the pH of WIPP brine A

Radiolytic Compounds Formed by Dissolution of Irradiated NaCl and MgCl2 · 6H2O in Water

“…In both cases, the sum of the oxidizing products was remarkably smaller compared to the amount of hydrogen. This effect was also observed from other authors [9,16] and could not be clarified until now.…”

H2 and Cl2 Production in the Radiolysis of Calcium and Magnesium Chlorides and Hydroxides

“…Very little information exists on the nature of the stable chemical products produced by the passage of ionizing radiation in solid chloride salts despite the importance of these materials in the storage of radioactive materials. Solid-state radiolytic effects such as the production of F, H, or V centers have long been examined in a number of chloride salts, especially NaCl. , A variety of studies have also been performed on salt brines, but as shown later there is very little relationship between the radiation chemistry of brine and a solid salt. − Pyrochemical processing of plutonium in chloride salt media has been proceeding for many decades. Significant amounts of plutonium-containing materials have accumulated that are often associated with large quantities of potassium, sodium, magnesium, and calcium chloride salts. − Salt content can be from about 8 to 20 wt %, depending on the degree of calcination.…”

Effects of radionuclide decay on waste glass behavior: A critical review

“…Sunder and Shoesmith [13] note that during radiolysis with spent fuel, 02-and OH are the predominant oxidizing agents, followed by H 2 0 2 and then 02. Alpha and gamma radiolysis of brines results in very high redox potentials due to scavenging of 90H radicals by halide anions and a resultant increase in the separation of H 2 from the aqueous phase [34,35]. Condensation of thin films of fluid on the glass samples may promote the formation of saline brines due to the rapid concentration increase of glass dissolution products in the limited volumes of water.…”
