Abstract

Abstract

Single temperature evaluation and multi-temperature analysis about the Pre-Cracked Charpy Specimens PCVN and 1/2 PCVN specimens of Chinese RPV steels were done. Both of the reference temperature T₀ of PCVN and 1/2 PCVN specimens were calculated. The results were corrected by the size criterion constant. The results showed that the size criterion constant equal 100 was appropriate for the application.
