Regulatory Guide 1.36 Compliance Testing
NRC Regulatory Guide 1.36 sets limits on leachable contaminants, such as chloride, fluoride, sodium, and silicate, in nonmetallic thermal insulation applied to austenitic stainless steel, because these ions can drive stress-corrosion cracking. Luvak tests insulation and related materials for these leachable ions by ion chromatography and related methods, reporting to the guide’s limits.
This testing helps nuclear suppliers and utilities confirm insulation materials meet Regulatory Guide 1.36 before use.
