ATS was founded in 1986 and specialized in Environmental Qualification (EQ) testing for the nuclear power industry. Our work soon expanded to include metrology, real-time software, and training support to the nuclear and process industries.
In 1989 Third Millenium Engineering division was created as we expanded our scope to include design and fabrication of test, calibration, and experimental equipment for both nuclear and non-nuclear customers.
In 2007 we expanded our laboratory capabilities to meet the requirements of new generation nuclear power plant designs. ATS was the first laboratory to meet the LOCA and MSLB requirements for the new Westinghouse AP1000 design.
The Nuclear Gateway division was formed to help suppliers and manufacturers of industrial equipment “break-in” to the nuclear industry by offering pre-qualification engineering tests. These tests allow evaluation of equipment for potential success in future Environmental Qualification tests.
