Thanks for this info. I have to laugh at the ‘soft beta radiation’ portion of it though. No ionizing radiation is good for you. Granted beta radiation is easier to shield.loner wrote: ↑Sat Dec 15, 2018 9:02 pmFor the first time in history, Russian nuclear scientists, using gas centrifuges, enriched the radioactive isotope Nickel-63, which can be used to create so-called "nuclear batteries."
the Electrochemical Plant in the city of Zelenogorsk, Krasnoyarsk Territory, made the gas centrifuge method of the radioactive nickel-63 isotope to a level of more than 69%."
“In 2019, specialists of JSC ECP, as part of their research and development, plan to achieve an enrichment of the nickel-63 isotope at more than 80%. The initial nickel-62 for these works is currently being irradiated in the RBMK-1000 power reactor at Leningrad NPP"
A non-naturally occurring nickel-63 radioisotope has the unique properties of soft beta radiation without dangerous gamma radiation.
I do like that they are researching this, even if public opinion will most likely regulate this to spacecraft. I did a bit of googling and found they are up to 3.3 Wh per gram with this technology. That’s a pretty good power density if it can scale.
