Pcm to percent
Type a value in pcm to get it in % instantly.
0.1%
That's about the same as a control rod step. That is about 0.15 dollars of reactivity.
What it means
How far from critical?
Dollars use β = 0.0065 for uranium-235. A plutonium-fuelled or high-burnup core has a smaller β, so the same pcm is worth more dollars.
The math
How to convert pcm to %
To convert pcm to percent, multiply by 0.001.
Example: 100 pcm × 0.001 = 0.1 %.
In the other direction, 1 % = 1,000 pcm.
