McWilliams Nuclear EDM Machines have been used in the diesel room, air system, feed water system, pump & valve room, reactor coolant, ECCS system, containment, and many other locations in various Nuclear Power Plants. The particles are then captured by a catch basin connected to tygon hosing that flows into a local floor drain. Our FME nuclear EDM machine creates a (FME) hole from 0.25 to 3.8 inches in diameter by vaporizing a hole through the wall of the pipe using a copper, brass, or graphite electrode to create burr-free holes.ĭeionized water, which is readily available in the Chemistry Lab of every Nuclear Power Plant, is used to flush out vaporized particles created during the EDM process. McWilliams’ nuclear division machining services are a versatile EDM machining solution for nuclear power plants. We Provide Safe and Reliable Nuclear Division Machining

Our one of a kind, portable Nuclear EDM Machine provides a clean, burr-free solution that delivers precise drilling with efficient, water-based cleanup. Outdated nuclear processes use a power drill hole saw to drill the holes, which must then be vacuumed to remove burrs and metal debris that can damage nuclear fuel rods. The holes are a critical factor in the operation of Nuclear Reactors because they alleviate gas accumulation that causes an interruption of water flow through the pipes. Our FME nuclear EDM machines are used to create (FME) holes in pipes throughout the nuclear power plant for the installation of vent valves and other components. McWilliams’ Nuclear EDM Machines are unique, compact and portable to provide efficient nuclear division machining that is compliant with FME nuclear programs. In 2008, McWilliams Sales & Service created a Nuclear Division to provide EDM machining services to nuclear power plants around the country. Preventing foreign debris is important in nuclear power plants because the presence of debris can cause outages, damage equipment, and increase the risk of worker injuries. During routine maintenance, Foreign Material Exclusion (FME) programs are used to prevent debris and foreign objects from entering components such as nuclear power generators. Nuclear Power Plants in the USA conduct maintenance on their Nuclear Reactors every 12-18 months during planned shutdowns called outages in the Fall or Spring seasons.
