  A significant amount of alpha particles, upto $\sim$ 35 MeV are produced in
the reactor environment. Alpha induced reaction on natural Zirconium, a reactor
component, upto 40 MeV has been measured using stacked foil activation
technique. The total neutron production cross section from all possible
channels for $\alpha$ energies upto 35 MeV is also estimated using TALYS 1.96.
The isomeric cross section ratio for the production of the radionuclide
$^{95}Nb$ has been measured and reported for the first time.
