On Bohr's Stationary Orbits?

Bohr proposed that electrons do not radiate energy as they orbit the nucleus, but exist in states of constant energy which he called stationary states

stationary states
A stationary state is a quantum state with all observables independent of time. ... It is also called energy eigenvector, energy eigenstate, energy eigenfunction, or energy eigenket. It is very similar to the concept of atomic orbital and molecular orbital in chemistry, with some slight differences explained below.

. This means that the electrons orbit at fixed distances from the nucleus (see Figure below).

What are Stationary of orbits?

In celestial mechanics, the term stationary orbit refers to an orbit around a planet or moon where the orbiting satellite or spacecraft remains orbiting over the same spot on the surface. ... A stationary orbit is sometimes referred to as a "fixed orbit".

Why electron does not lose energy in stationary orbits?

Stationary orbit means the electron stays there. If it were radiating, that would mean losing the energy and that means electron jumping to lower state => orbit was not stationary.
