China successfully acquires Nickel-64 isotope CNNC, PUBLISHED 16.01.2025 The Research Institute of Nuclear Industry Physical and Chemical Engineering (IPCE), a subsidiary of China National Nuclear Corporation (CNNC), recently successfully acquired Nickel-64 isotope with over 99 percent abundance per gram, marking that China has become a global leader in the research and development of new-type stable isotope. The extraction of Nickel-64 isotope requires special separation techniques to elevate the enrichment level of 36-neutron atoms to high abundance. Additionally, the materials used in the Nickel-64 isotope enrichment process are highly unstable, which poses strict requirements for relevant facilities and techniques. Right now, there are only several countries which have mastered Nickel-64 isotope extraction technology. Therefore, the price of Nickel-64 isotope is extremely high, equivalent to that of several hundreds of gold by weight. Nickel-64 is the precursor nuclide of radioactive nuclear copper-64 isotope. Copper-64 is a new PET imaging isotope with a half-life of 12.7 hours, which is featured with high clarity, a wide-scanning time window, and reliable supply. Copper-64-labeled drugs have been widely used in the diagnosis of neuroendocrine tumors, hypoxic tumor and Alzheimer's disease. The IPCE has further strengthened its cooperation with C-Ray Pharmaceutical (Chengdu) Co., Ltd and employed the latter's automatic production facilities and nuclear isotope research strength in the production of copper-64 isotope with nickel-64, achieving an EOB capacity of 2Ci. The quality indicators have surpassed both international and domestic standards, filling a domestic gap in the self-sufficient supply system for key medical isotopes. Other news: 38 nuclear power units with a total capacity of 29.3 GW are scheduled to be commissioned by 2042. Rosatom starts pilot operation of a fuel fabrication facility for the BREST-OD-300 fast reactor Currently, the facility operators are mastering the technology and gaining experience. Turbine installation completed at Unit 1 of Akkuyu NPP The Akkuyu NPP turbine-generating unit consists of a combined high- and medium-pressure module, two low-pressure modules, and a generator. |
Hero of the day 
National flag of Russian Federation hoisted on Yakutia nuclear icebreaker Yakutia is the fourth icebreaker actually built under Project 22220. Its service life is 40 years. As is the tradition, the icebreaker is named after a region adjacent to the Northern Sea Route. INTERVIEW
