In Non destructive testing, What is the design temperatures?
Direct Answer
Option C: colder than –10°C
Non-destructive testing (NDT) requirements for materials are intensified when design temperatures fall below -10°C. This threshold is critical because lower temperatures increase the risk of brittle fracture in steel, necessitating rigorous weld inspections to ensure the structural safety of the fuel containment system under cryogenic operating conditions.
