Unless you are implying that the reaction is not useful because the Ni63 would remain radioactive for so long. However Ni63 could be a useful portable/remote/no-moving-parts energy source. Initially about 32 W/kg, dropping off to half that after 100 years. Think of the sort of applications that currently use solar panels. Regards,
