Assembly Types 0, 1, 2, and 3 Schematic of the Grid Spacer Estimates of the Grid Spacer Dimensions Assumptions: 1. Strip thickness of 0.3 mm; 2. Homogeneous arrangement. Dimensions used as reference values: 1. Outside rod diameter of 12.3 mm; 2. Outside water rod diameter of 15.0 mm; 3. Rod pitch of 16.2 mm; 4. Grid spacer total width of 132 mm. Technique used: 1. Simple measuring/scaling technique by applying two different scale ratios (vertical and horizontal) to the side view drawings (as provided by JNES). 2. Adjustments to the above-mentioned reference values to match all dimensions. Comment: Errors are possible because the graphics made available might have been deformed through different copying processes.
