Janesville, WI – Today, Congressman Bryan Steil (WI-01), announced that the Department of Energy’s (DOE) Office of Energy Dominance Financing will award SHINE Chrysalis, LLC in Janesville, WI a $263 million loan to support the construction of a new medical manufacturing facility in Janesville. The facility will use fusion and fission technology to provide a secure domestic supply of Molybdenum-99 (Mo-99), a medical isotope used in life-saving diagnostic imaging. Once completed, this will be the largest such facility in the world.

In May and September of 2025, Steil wrote to DOE Secretary Chris Wright regarding SHINE’s innovative work on Mo-99 and the importance of the Chrysalis project.  He emphasized the need for strong public-private partnerships in building domestic manufacturing.

Following the announcement, Steil released the following statement:

“American supply chains ensure healthcare workers and patients have access to the lifesaving tools they need to identify and fight diseases like cancer and heart disease. This critical work to save lives will now be done right here in Janesville,” said Steil. “Thank you, Secretary Wright and the Department of Energy for investing in Wisconsin and congratulations to SHINE on receiving this loan.”

Background:

  • SHINE Technologies is a radiopharmaceuticals company based in Janesville. 
  • Among its products, SHINE manufactures Molybdenum-99 (Mo-99) as a medical isotope for use in diagnosis and treatment of diseases. 
  • Mo-99 rapidly decays within 66 hours, necessitating a continuous supply chain which often comes from foreign countries. 
  • Congress has worked to promote Mo-99 production in the US through companies including SHINE, through the American Medical Isotopes Production Act of 2012.
  • Mo-99 isotopes and decay products are used in over 40,000 medical procedures each day to diagnose heart disease and cancers, study organ structure, and perform other medical applications.
  • According to DOE estimates, once complete, the Janesville facility will produce more than 75% of U.S. Mo-99 demand.
  • The facility will also enable Mo-99 delivery 24-36 hours faster than imported sources.
  • This will be the largest Mo-99 production facility in the world.
