Engine Systems Capabilities

Commercial Grade Dedication

ESI specializes in the dedication of commercial grade items intended for nuclear safety-related applications. This parts qualification process meets the requirements of 10CFR50 Appendix B and 10CFR Part 21, thereby providing our customers with assurance that the parts and services conform to applicable industry requirements.

Testing

To support our parts qualification program, ESI performs a wide variety of tests using specialized test equipment. This includes material, functional, seismic shake table, and environmental testing. ESI’s material lab utilizes:

Optical emissions spectroscopy
X-ray florescence analysis
Fourier transform infrared spectroscopy (FTIR)
Rockwell, Brinell, and Knoop microhardness

The functional test lab includes apparatuses to test temperature and pressure sensitive devices along with adjustable voltage and current sources for electrical testing. Within the seismic bay is a tri-axial shake table capable of duplicating customer specific seismic spectra while monitoring the component or assembly for functionality.

Controls

In addition to the worldwide nuclear distributorship for the Woodward product line, ESI has the in-house expertise to assist customers with all aspects of their controls needs. Whether it is product selection, component configuration, or functional testing ESI has the solution. The application may be to control prime mover speed or for generator voltage regulation.
