<p>The piping components of primary heat transport system in nuclear power plants are subjected to cyclic loads during seismic events. Due to the cyclic loading, the fracture resistance and load-carrying capacity of piping components will reduce. The associated parameters of cyclic loading include the load history, load ratio, load range and the number of loading cycles to failure. Fracture studies were carried out on straight pipes of SA312 Type 304 LN welded stainless steel with circumferential through-wall crack subjected to cyclic loading under displacement control as well as load control. In the present study, the cyclic <i>J</i>-integral (Δ<i>J</i>) is evaluated for specimens subjected to cyclic loading under load-controlled and displacement-controlled conditions using six methods, namely <i>η</i> factor method, GE-EPRI method, reference stress method, R₆ method, limit load method and HRR method. Using the experimental load versus load-line displacement curves and crack growth data, the cyclic <i>J</i>-integral (Δ<i>J</i>) is determined for all specimens under cyclic loading. A significant reduction in fracture resistance was observed under cyclic loading. Further, crack growth resistance (<i>ΔJ–R</i>) curves were generated for the pipe specimens under load control and displacement control loading conditions. It was observed from the generated <i>ΔJ–R</i> curves that (1) under load-controlled mode, the <i>η</i> factor method yielded the highest values of cyclic <i>J</i>-integral with respect to crack extension and the R₆ method consistently yielded the lowest value among the different methods, and (2) under displacement-controlled loading, the HRR method yielded the highest value suggesting that it predicts higher fracture resistance and the R₆ method consistently yielded the lowest value among the different methods. The developed <i>ΔJ–R</i> curves are primarily useful to develop a stable crack growth model and to determine the initiation fracture toughness. </p>
