Recommendation for the negligible creep domain for P91 : MATerials TEsting and Rules MATTER Deliverable 5.3
Stefan Holmström (JRC-IET), Jia-Chao Chen (PSI)
The report is a recommendation on the methodology for determining the negligible creep (NEC) domain for P91 steel. The objective to define the actual TNEC curve for P91 was fully reached and time safety factors involved in the recommended curve was calculated and found to be conservative. The curve can be recommended for use in the nuclear design codes. The report also contains the new data collated in the negligible creep domain (375-450°C).
