WebHistory. The progenitor of the BWR line was the 5 MW Vallecitos Boiling Water Reactor (VBWR), brought online in October 1957.. BWR-1. BWR Type 1 (BWR-1, BWR/1): In 1955 GE developed their original VBWR design into the 197 MW Dresden 1 (6×6, 7×7) reactor, embodying the first iteration of GE's BWR/1 design. Dresden 1 used forced circulation … Reactor start up (criticality) is achieved by withdrawing control rods from the core to raise core reactivity to a level where it is evident that the nuclear chain reaction is self-sustaining. This is known as "going critical". Control rod withdrawal is performed slowly, as to carefully monitor core conditions as the reactor approaches criticality. When the reactor is observed to become slightly super-critical, that is, reactor power is increasing on its own, the reactor is declared critical.
