By the end of Operation Crossroads in the summer of 1946, the US had built a total of 9 atomic bombs and detonated 5 of them, leaving only 4 in the stockpile. Records obtained by the Bulletin of the Atomic Scientists suggest that by the end of 1946 the US had built 5 more atomic bombs, ending the year with 9 in the stockpile.
While the Hanford reactors had a design capacity of 3 atomic bomb cores every month, its very obvious that they were being operated far below capacity through 1945 and 1946 to minimize neutron irradiation damage to the graphite moderator and/or shutdown for repairs frequently.

Why did the US use atomic bombs instead of trying an invasion of japan?
The US was actually planning both (23 atomic bombs in 1945 and invasion in late october 1945 followed by more atomic bombs in 1946 and a second invasion in spring 1946), the invading troops would be fighting on the world's first "atomic battlefield" with atomic bombs detonating within sight of invading US troops roughly twice each week through the duration of the invasion. Both Japanese and invading US troops would be exposed to fallout from these bombs every day.Fortunately the Japanese surrendered after only the first 2 atomic bombs and more than a month before the first planned invasion, making the rest of the US plans unnecessary.
How long did it take to make all three atomic bombs?
As of august 1945 the US had the industrial capacity to make 3 atomic bombs a month. In november 1945 this would increase to 7 atomic bombs a month. As Japan surrendered before this, the US scaled back production and had only made 9 atomic bombs by the end of Operation Crossroads in the summer of 1946, five of which had been detonated.
