The ETRR-2 is the second Egyptian research reactor. The reactor is of an open pool type and shielding and dose calculation is one of the most important scopes for the reactor safety. The core radiation source has been calculated using the Madland-Nix model (MNM) for a prompt fission neutron spectrum. The ANISN code has been used to determine the flux and dose through the axial and radial layers of the reactor shielding. It has been found that the calculated dose in the outer area of the reactor shield does not exceed the maximum allowable dose level which is in a good agreement with the measurement.
