ERPI Research Paves Way for Lokring Fittings to be used in Constellation Safety-Related Applications

ERPI Report Cover

After collaborating with EPRI, Constellation will have 680 safety-related fittings manufactured by Lokring Technology, LLC on its nuclear fleet shelves ready for use this year. The fittings—an alternative to socket-welded fittings—will reduce installation time, cost, radiation exposure and outage critical path.

Expanding Lokring Fitting Applications

Lokring’s line of mechanical fittings for connecting small-diameter piping and tubing operate successfully in marine, power, and process piping systems. The company’s products—including compression-type fittings that connect tubing and piping with no welding or grinding—previously were installed in several non-safety-related applications at nuclear power plants.

However, the fittings had not been proved compliant with Nuclear Regulatory Commission (NRC) 10 CFR 50 Appendix B program requirements nor with the ASME NQA-1 Code requirements.

The Success Story talks about how they worked through the process to get these products qualified and showed how they reduced radiation exposure.
