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.

A conceptual fusion synfuel production system has been developed with the unique features of: (1) a fusion blanket producing high-temperature (1250°C) process heat, and (2) the GA sulfur-iodine thermochemical cycle. The system incorporates a two-zone blanket which achieves a tritium breeding ratio of 1.1 while delivering a high fraction (30%) of the fusion heat at high temperatures (1250°C). The multiple barriers to tritium permeation in the blanket design permit the hydrogen product to meet 10CFR20 regulatory requirements without stringent requirements on the tritium recovery systems. A ceramic heat exchanger, incorporating SiC tubes and headers to contain the process stream and a cooled, Inconel 718 pressure shell to contain the helium, was designed for transferring the heat from the high-temperature coolant to the process. A good heat-line match of the blanket heat-source temperature distribution to the requirements of the thermochemical plant was attained under the dual goal of maximizing process efficiency and minimizing the hydrogen cost. The results are a process efficiency of 45%, an overall plant efficiency of 43%, and an estimated cost of hydrogen of $12 to $14 per Gigajoule of hydrogen ($11 to $13 per million Btu).
