It is because according to Bohr , an electron can revolve in that orbit only whose angular momentum is an integral multiple of h/2π i.e.

mvr = nh/(2π)

So, there are only some orbits which satisfy this condition . So, in that orbits , although the electron is accelerating , but then also it don’t release energy because in that particular state , the electron is stable.

But, now you should not worry about bohr model because it is failed. Now, quantum model is there according to which the electron is not in an orbit but, it is in an electron cloud.

Please approve it if you like it.

Thanks

Because electrons in Bohr model are only occupying the stable states.The orbits are quantised and electrons can only occupy only those orbits around the nucleus.
