Why is electron rotating in h/2pi orbit does not radiate energy

We don't look at the electron as a particle rotating the nucleus instead we say its a standing wave surrounding the nucleus as first described in the Bohr model of the atom.

and as such doesn't radiate electromagnetic radiation. Later Quantum Mechanics refined it further explaining things that the Bohr model failed at.

Atomic physics

Here's some info on the standing wave concept:

and here's the square well problem that usually starts the discussion of Quantum Mechanics, its simpler than the Bohr atom but illustrates the same principles:
