I whakaturia a NSEN i te tau 1983, he mea motuhake i roto i te mara o nga reera rererere rereke.I muri i nga tau o te torotoro me te mahi, kua hangaia te raupapa hua o mua:

• Takitoru rererere rererere rereke
• Rarere pūrerehua mahi teitei
• Te konganuku ki te konganuku rewharewha rewharewha
• -196°Cryogenic rerererererererere
• High pāmahana tiaki ahi rererere valve
• Rererererererere papamuri
• Rererererererere atete wai moana

I roto i te mara ngaio, arotahi ki runga i nga maru rerehua.Kei te whakapai tonu a NSEN i ona ake tohu me te whakamatau i tona kaha.
