Pitch-to-diameter ratio

WebbThe fuel rods in a PWR are 1.1 cm in diameter and 3.66 m long. The rods are arranged in a square lattice, as shown in Fig. P4.4, with a pitch-to-diameter ratio of 1.33. For a period of time during a particular core uncovery incident, the core remains at 40 bar pressure, while saturated liquidwater enters the bottom of the core. Webb1. The Minimum part PD (pitch diameter) is larger by 6 X the “One Value Plating Thickness”. 2. The Maximum part PD (pitch diameter) is larger by 4 x the “One Value Plating Thickness”. 3. The Tap “H” = a PD that is located at 40% of the before plate limits – minimum after plate limit \ .0005 (“H” limit increment). Selecting the ...
