Ko te "Nautilus", i neke atu i te 513,550 maero moana (951,090 km). Ko te tauira pūkaha karihi e whai ake nei ko te Experimental Boiling Water Reactor, te kaiwhakawhanake o te maha o nga tipu karihi hou, me te Experimental Breeder Reactor II (EBR-II), i whakahekehia e te konutai, me te whakauru i tetahi whare tukurua wahie. I whakarerekētia a EBR-II ki te whakamātautau i ētahi atu hoahoa pūkaha, tae atu ki tētahi pūkaha tere-neutron, ā, i te tau 1982, te ariā o te Pūkaha Tere Integral - he hoahoa hurihuri i tukatuka anō i tōna pūkaha ake, i whakaiti i ōna ururua ngota, ā, i mau i ngā whakamātautau haumaru o ngā hapa ōrite i pā ki a Chernobyl me Three Mile Island
