I whakatūria a NSEN i te tau 1983, he tohunga ki te ao o ngā takirere pūrerehua rerekē. Whai muri i ngā tau maha o te tūhuratanga me te mahi, kua hangaia te raupapa hua o nāianei i raro nei:

• Takirere pūrerehua rerekē toru
• Takirere pūrerehua mahi teitei
• Takirere pūrerehua whakarewa ki whakarewa
• -196℃ takirere pūrerehua Cryogenic
• takirere pūrerehua tiaki ahi pāmahana teitei
• Takirere pūrerehua ārai
• Takirere pūrerehua ātete wai moana

I te ao ngaio, arotahi ki ngā takirere pūrerehua. Kei te whakapai tonu a NSEN i ana ake tohu me te whakaatu i tōna kaha.
