The case of active nuclear reactors (and their fission-by products) presents a much more
challenging task as it is still not clear whether a reactor capable of withstanding re-entry can
actually be manufactured. The risk associated with moving used cores into a “graveyard”
orbit, selected specifically for disposal of nuclear powered spacecraft taking into account the
probability of future collisions, would be lower than re-entry with a used nuclear core. This
“graveyard” orbit needs to be selected with the aim to minimise space debris collision and
reduce future hazards.
Upon reaching their end of life, all spacecraft using nuclear reactors or using an RTG in
geosynchronous orbit, shall be transferred to a “graveyard” orbit. This graveyard orbit should
be selected in such a way as to assure stability (i.e. do not decay or present a collision hazard)
for the duration of the nuclear fuel’s half-life or until the radiation emitted does not pose a
hazard for human populations.
