By the end of this second expansion the U.S. government was $4 billion poorer and plutonium production had doubled at Hanford. HAPO was directed to speed development of a new chemical separations process known as reduction-oxidation (REDOX), and to build a giant plant to deploy it. Six new labs were built in the 300 Area of Hanford to find new ways to produce plutonium that would be more efficient. A machine shop was also built; these new buildings became known as the "Tech Center". Eighteen more waste tanks were constructed, along with two waste evaporators because tank space was rapidly running out.
HW was seen as so vital to national security that 3,000 men in three anti-aircraft battalions were deployed Camp Hanford in March 1950. They established a base administration area near the North Richland trailer park and 16 forward positions on the Hanford site.
