In prosperous countries, most people die of cardiovascular disease, cancer, diabetes, lung and respiratory tract conditions and dementia. In all these cases, apart from diabetes, the specialist will probably refer the patient to the nuclear medicine specialist.
This referral is usually to perform a scan (90% of cases), but increasingly it also involves (cancer) treatment or pain management.
The photo taken by the nuclear medicine specialist and the prescribed treatment both involve medical isotopes. And those medical isotopes? They come from a nuclear reactor.
In the nuclear reactor, uranium atoms are split under controlled conditions. This creates a cloud of neutrons. By firing these neutrons at a target, they become radioactive.
This produces isotopes: artificial substances with radioactive properties which we can use in medicine. We currently use 24 reactor isotopes for medical purposes. And this may increase in the future.
After the irradiation, a series of purification and processing steps takes place in various laboratories. The entire nuclear infrastructure consists of the reactor, laboratories and the parties which quickly prepare the irradiated materials.
Due to the short life span of the isotopes, having all the parties in one location and the availability of sophisticated logistics are vital to be able to rapidly transport the irradiated materials to the hospitals.

Without medical isotopes, we can't do anything. And our Nuclear Medicine department at the Antoni van Leeuwenhoek Hospital might as well just close.
To produce radiopharmaceuticals for the treatment of cancer patients worldwide, the NRG reactor in Petten, as part of an international reactor network, is of great importance. - Dr. Richard Henkelmann
Since the closure of the Canadian NRU reactor, the Netherlands has become the world's largest manufacturer of medical isotopes.
Because Technetium-99m dominates in terms of market share, the expectations for this market are crucial. A slight growth is expected over the next 20 years. This growth can mainly be attributed to countries where nuclear medicine is currently still in its infancy.
In Western countries, there has been a particular rise in demand for therapeutic isotopes. For example, there are high expectations for lutetium-177 and holmium-166.
When the reactor is on, there is a characteristic blue glow. In the reactor core, small enough to fit under an office chair, isotopes for medical applications are produced.
The HFR in Petten has been producing medical isotopes for over 60 years. However, the reactor in Petten AND other reactors worldwide are getting old. Within 15 years, three quarters of the reactors which are currently suitable for producing medical isotopes will be decommissioned.
If the HFR, which is responsible for 70% of the European production of medical isotopes, is not replaced by a new reactor, the availability of diagnostic isotopes will be at risk. For the (growing) market of therapeutic isotopes, that will create an impossible situation. Many patients could then no longer be treated with therapeutic isotopes.
We are therefore working on a new isotope reactor: PALLAS.
Without isotopes from the reactor, we cannot provide the best possible care. And there is no way to produce isotopes for treatment.
