Description/Abstract Lattice parameters, fast fission ratio, initial conversion ratio, thermal neutron fine structure, thermal neutron spectrum parameters and buckling, have been measured at CRNL for a wide range of natural uranium lattices.The lattices consisted of regular arrays of fuel clusters, containing natural U metal, UO$sub 2$, UC, U$sub 3$Si/Al cooled by D$sub 2$O, AIR, organic liquid and in a few cases H$sub 2$O, in D$sub 2$O moderator, for a wide range of lattice pitches.$sup 238$U resonance absorption rates in these lattices can be derived from the lattice parameters.These absorption rates have been related to effective $sup 238$U resonance integrals by means of the EPITHET computer code.(auth)
