Alert: Unplanned HFR Outage Will Impact Isotope Supply


On January 24, the Emergency Response Team (ERT) of Nuclear Medicine Europe (NMEu) communicated that there will be a delay in the restart of the HFR Reactor that will impact the supply of Mo-99 and Lu-177 in coming weeks.

The delay is due to discovery of a water leak in the reactor beam tube cooling system. The NRG, which operates the HFR reactor, has not yet been able to discover the root cause of the leak and has put a project team in place to determine a plan of action; additional inspections are expected this week. After the root cause is discovered and repaired, regulatory review and approval must take place before the reactor can resume service.

HFR was scheduled to produce both Mo-99 and Lu-117 this week, so the delay will impact supply in coming weeks. “Medical institutions should contact their radioisotope suppliers to determine the specific impact on their orders,” per the communication from the ERT. Read the full letter here.

Last week, the Department of Energy (DOE) and Department of Health and Human Services (HHS), in accordance with the American Medical Isotopes Production Act of 2012 (AMIPA), issued a joint Secretarial certification that there is a sufficient global supply of Mo-99 produced without the use of HEU available to meet the needs of patients in the United States and that it is not necessary to export United States-origin HEU for the purposes of medical isotope production in order to meet United States patient needs. This certification triggers a congressionally mandated ban on exports of HEU for foreign medical isotope production effective January 2, 2022. The Federal Register notice may be viewed here

On January 2, 2020, DOE published a Federal Register notice (85 FR 3362) certifying that, at the time, there was an insufficient global supply of Mo-99 produced without the use of HEU and that the export of U.S.-origin HEU for the purposes of medical isotope production was the most effective temporary means to increase the supply of Mo-99 to the domestic U.S. market. This certification was effective for no more than two years from the effective date of January 2, 2020. The Federal Register notice stated that DOE would conduct periodic reviews of the domestic U.S. and global Mo-99 market and would work toward a certification to Congress, regarding the sufficiency of supply as soon as the statutory conditions are satisfied.

In October 2021, DOE sought public input as part of its certification development process and analysis to determine the sufficiency of Mo-99 supply to meet U.S. patient needs. SNMMI's comments may be found here.

Yesterday, Jubilant Pharma of Greater New York announced that its supplier is experiencing shortages of Sulfur Colloid that may extend until December. Therefore, the following ordering restrictions will be implemented for all Sulfur Colloid doses:

  • No cold kit will be sold
  • No weekend orders
  • There will be no orders allowed for Fridays
  • Only orders for first run production will be allowed
  • Maximum activity will is 10 mCi and latest calibration time will be 12:00
  • Orders allowed for Monday through Thursday
  • Only one vial is prepared per day. Once the activity for that vial is allocated, no more orders can be accepted for that day.

To request an accommodation, please contact your pharmacist.

August 19, 2021 Update on CholetecTM (Technetium (99mtc) Mebrofenin) Shortage

As of today, Choletec commercial availability from one manufacturer is anticipated for August 30th. That manufacturer is working on a routine production plan. Customer orders will be filled based on order date and available inventory. Until the manufacturer achieves a routine production schedule, product allocation will be in place due to the limited inventory.

June 24, 2021 Update on CholetecTM (Technetium (99mtc) Mebrofenin) Shortage

While a global shortage of Choletec (technetium (99mTc) mebrofenin) persists due to a vial shortage, we have reached out to various suppliers. More supply is on the way and should be released beginning mid-July. 

June 8, 2021 Update CholetecTM (Technetium (99mtc) Mebrofenin)

Today, one of our members reported an isotope shortage of Choletec (technetium (99mTc) mebrofenin). After conducting further research as to the cause of the shortage, the Society learned that the culprit is a shortage of vials.  This shortage is not unprecedented. Some time ago, there was a DTPA shortage because of a shortage of caps for the vials.

March 16, 2020 - Update 

SNMMI President Dr. Vasken Dilsizian released the following statement addressing how the COVID-19 pandemic may affect the supply of Mo-99.

Dear Fellow SNMMI Members,

Much like you, the SNMMI leadership has been closely following the rapidly evolving COVID-19 situation—monitoring the latest recommendations provided by the U.S. Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) to help address its inevitable impact on the nuclear medicine and molecular imaging community.  In line with the SNMMI’s mission to improve human health by advancing nuclear medicine, molecular imaging, and radionuclide therapy; SNMMI’s primary focus is on how this issue may affect our ability to care for patients; more specifically, how the COVID-19 pandemic may affect the Mo-99 supply situation.

Mo-99 Supply 

The SNMMI is particularly paying close attention to how the COVID-19 pandemic might affect different parts of the Mo-99 supply chain including production, target processing, and transportation. As you may imagine, many factors can affect this supply chain, including quarantines and closures of schools that result in the absence of key staff, as well as disruptions in the international transportation network.  In order to keep our members as informed as possible, SNMMI is currently taking the following steps:

  • Monitoring official government sites to obtain the most up-to-date information about the status of Mo-99 production and processing facilities;
  • Reaching out to our industry partners and working with trade organizations to ensure that we provide you with the most up-to-date and accurate information Mo-99 availability; and
  • Updating our membership as soon as we learn of any interruptions to the Mo-99 supply chain.

 At this time, no Mo-99 shortages have been reported. Moving forward, SNMMI will remain in close contact with government agencies, trade organizations, and other stakeholders in the nuclear medicine and molecular imaging community to help to ensure an adequate supply of Mo-99.

Warm Regards,

Vasken Dilsizian, MD

SNMMI President

October 31, 2018 - Update 

A significant shortage of Mo-99 is expected for the first half of November. The NTP facility in South Africa, which has experienced problems since late last year, has not yet been able to return to service, and a technical issue has developed with the High-Flux Reactor (HFR) in the Netherlands, which is now on unplanned shutdown.

The unexpected HFR shutdown coincides with a planned 11-day shutdown of the OPAL reactor in Australia that began October 29, so significant shortages of Mo-99 are anticipated starting in early November. With significant shortages anticipated, it is essential that users contact their generator/nuclear pharmacy providers for advice about their local situation. The Association of Imaging Producers & Equipment Suppliers (AIPES) Emergency Response Team is closely following the situation. The group issued an update on October 30, and SNMMI will post updates as they become available.

July 16, 2018 -Update

NTP Radioisotopes in South Africa reports that they expect to meet with regulators this week regarding their request to resume Mo-99 production operations. With OPAL having a scheduled shutdown from July 16 – 20 will make things more challenging. The AIPES Emergency Response Team is scheduled to meet again on July 23, 2018.
