Are these nuclear Diamond batteries??

The following submission statement was provided by /u/Aeromarine_eng:
European researchers are developing batteries that use a radioactive isotope to power long missions in the Solar System.
ESA has relied on US or Russian partners, which have used plutonium-238 batteries.
Americium’s big advantage over plutonium is that it is cheaper and more abundant, repurposing waste that would otherwise be useless.
Americium has a longer half-life than plutonium-238, which means it lasts longer but packs less power per gram. But because americium is more readily available, producing one watt of power costs about one-fifth as much as it does using plutonium.
Over the next three years, the European Devices Using Radioisotope Energy (ENDURE) team will develop prototypes into models that can be tested in mission-like conditions.

What would happen if these became unstable mid launch?????

Depends on the volume. Generally, about the same as any of the RTG’s we’ve launched on NASA or ESA probes. Not much. It burns up and distributes in the atmosphere to almost nothing in a wide swath. But again it really depends on the volume and when the malfunction happens.
There was a huge uproar during the Cassini–Huygens probe launch and NASA studies because of it.

Radioactive batteries have been in use since the 60s. I'm pretty sure the safety of using them has been figured out.
