No and no.

Explanation:

Acceleration is the rate at which velocity changes. If the velocity is not changing, there is no acceleration.

Velocity is a vector quantity. This means that direction is also a part of velocity. In circular motion, the direction is always changing, so the velocity is always changing. In circular motion, constant speed is possible, but constant velocity does not occur.
