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.

At present, there are no regulatory guidelines to follow for US fusion power plant construction and operation. Thus far, the Department of Energy (DOE) has been regulating existing fusion experiments, following the 1996-1999 DOE Fusion Standards and using the spirit of the ASME (American Society of Mechanical Engineers) code. Considering this reality, a few options emerged for licensing ARIES-type power plants and the like. Developing new fusion-specific regulations stands out as the most logical option, but requires well-coordinated effort between DOE, regulatory agencies, and the fusion community with considerable funding and long lead-time. Nevertheless, a few recent developments seem promising: 1) The US Nuclear Regulatory Commission (NRC) plans to assert regulatory jurisdiction over commercial fusion devices, and 2) the ongoing effort within ASME will develop rules for the construction of fusion-energy-related components. The most recent NRC, ASME and fusion licensing developments are reviewed in this paper. In addition, an interesting comparison with ITER was made to foresee how US fusion power plants could leverage from ITER.
