Materials Testing Reactor was mankinds first nuclear reactor for testing materials.1953Submarine Thermal ReactorAlso known as S1W, the Submarine Thermal Reactor marked the birth of Americas nuclear navy.1955Special Power Excursion Reactor TestThe SPERT experiments (I-IV) regularly pushed reactors far beyond normalsafety limits in order to discover whatthe normal safety limits were. 1953Boiling Water Reactor No. 1 Boiling Water Reactor No. 1 (BORAX-I) was the first of five reactors to test the safety and operating parameters of reactors using boiling water as a moderator and coolant.'
