ZPPR assembly 13. Detailed work plan No. 19: transformation from 13B/2 to 13B/3
At the completion of the ZPPR-13B/2 construction, the broken-hexagonal-blanket configuration of ZPPR-13B/2 will be immediately converted to the dispersed-blanket configuration of ZPPR-13B/3. This conversion will consist of interchanging blanket drawers and fuel drawers with a net subtraction of fuel drawers and a slight radial contraction of the reactor core. The fraction of double-fuel-column drawers will increase slightly. Fuel/blanket interchanges will be made in a series of steps from the center outward. Outer-radial blanket and radial reflector boundaries will be adjusted in a single step. Flux distribution measurements will be made at each step using the 64 in-core fission counters. Final criticality will be achieved by adjusting the ratio of double to single fuel-column drawers.
