SHIELDING OF A FAST BREEDER REACTOR--I. THE PRIMARY SHIELD

Technical Report ·
OSTI ID:4337076
The differing shieldmg requirements of a fast breeder reactor and a thermal reactor are discussed. The functions of a stainless steel layer inside the reactor vessel of a fast breeder are outlined: neutron reflector, gamma-ray absorbing thermal shield, and an inelastic neutron scatterer to protect the vessel walls against radiation damage. The use of borated graphite outside the vessel is discussed. The rotating plug shield is described. Shielding calculations and a primary shield design drawing are given for the Fermi Fast Breeder Reactor. (M.H.R.)
