QSA Global, Niowave to collaborate on Ac-225 production using Ra-226
QSA Global, a provider of radioisotope products, and Niowave, a Michigan-based producer of medical radioisotopes, announced that the companies will codevelop a scalable radium purification process using Niowave’s radium-226 processing technology to meet the demand for actinium-225, an alpha-emitter used in the treatment of cancer. According to the companies, the strategic partnership marks a significant advancement in the field of radiopharmaceutical technology, enhancing the supply chain for critical radioisotopes, including Ac-225.
Niowave uses a closed-loop cycle to produce high-purity Ac-225 and other alpha emitters from Ra-226 using a superconducting electron linear accelerator. According to the company’s website, the electron beam impinges on a photon converter to irradiate the Ra-226, inducing a photon-neutron reaction to Ra-225, which decays to Ac-225.

The MultiScale ThermoHydrologic Model (MSTHM) is used to predict thermal-hydrologic conditions in emplacement drifts and the adjoining host rock throughout a proposed nuclear waste repository. This modeling effort simulates a lower-temperature operation mode with a different panel loading than the repository currently being considered for the Yucca Mountain license application. Simulations address the influence of repository-scale thermal-conductivity heterogeneity and the influence of preclosure operational factors on thermal-loading conditions. MSTHM can accommodate a complex repository layout, a development that, along with other improvements, enables more rigorous analyses of preclosure operational factors. Differences in MSTHM output occurring with these new capabilities are noted for a new sequential waste-package-loading technique compared with a standard simultaneous-loading technique. Alternative approaches to modeling repository-scale thermal-conductivity heterogeneity in the host-rock units are investigated, and a study incorporating geostatistically varied host-rock thermal conductivity is discussed.
