Ebwr Core 1a Physics Analysis

A Performance Analysis of the Ebwr at Various Power Levels

“…Having established the subregions, the same procedure was followed as outlined in detail in Ref. 5. Void-dependent cross sections were calculated, and for regions 3 and 6 corrections for the control rod were made accordingly.!")…”

Physics Analysis of Proposals for Ebwr Core 2

“…The atomic densities given in Table 1 correspond to the "large" unit cell in EBWR associated with "Class A" cross sections as defined in Ref. 2, in which the basis is taken as the repeating 9-element sublattice of the EBWR, 12.75 in (32.385 cm) square, complete with its adjoining control rod channels, spacers and other structural materials. Stainless steel fueled followers are incorporated into the composition.…”

“…The cross sections of the reflector water are the same as those reported in Ref. 2. A fictitious material having the properties of a l/v-absorber was used to represent fission products.…”

“…In addition to the fuel element cladding, other structure present (see Ref. 2) includes: box material (also assumed to be Zr); control rod guides (Zr); control rod followers (Zr); and spacer material (Zr and HgO).…”
