Snubber Testing and Rebuild Services

NTS offers comprehensive services to support plant maintenance and surveillance programs for all types and sizes of mechanical and hydraulic snubbers.

Our engineers and technicians work with proven equipment to perform repair and functional testing on site or at NTS Huntsville facility, the only off-site Radioactive Material Licensed facility for snubber services in the country. This full-service, one-stop approach works to keep your plant on schedule during outages. Our Quality Assurance Program is approved by more than 40 utilities and is in accordance with applicable portions of 10 CFR 50, Appendix B, ANSI N45.2 and 10 CFR.
