Temporary power for refuel and uprate outages

A refuel outage is measured in days that each cost real money, and the work happens where permanent power was never installed. Porta-Safe units put GFCI-protected 120 V and welding power at the job, built to the plant's specification and documented the way a nuclear QA department expects.

What the environment adds

Documentation
Exact specification agreed to before the build; the documentation package issued with the unit is set to each customer's requirements.
Ruggedness
Heavy-gauge welded frames and enclosures for units that are craned, forked and moved through containment access every outage.
GFCI everywhere
Every receptacle a person plugs a tool or a light into is ground-fault protected.
Repeatability
Once a unit is specified for a plant, the next one is the same drawing — fleets stay consistent across outages.

Built by the OEM

Porta-Safe is a division of JNT Technical Services, Inc., which also supplies the nuclear industry through its Torq N' Seal® tube plug line. The people who quote a unit are the people who build it, so a question about a receptacle standard or a frame dimension gets an answer, not a callback.
