When difference(s) exist from the original item, an equivalency evaluation is performed to determine if any changes in design, material, manufacturing process, form, fit, or function could prevent the replacement item from being interchangeable under the design condition of the original items and performing its required safety function.

We have extensive experience in successfully performing Item Equivalency Evaluations on a wide variety of components (mechanical, electrical, etc.) for a wide range of applications, to meet nuclear safety standards.

The equivalency evaluation is documented and includes the following:

Identification of the change(s) in design, material, manufacturing process, configuration, form, fit, or function of the replacement item that is different from the original item.

Evaluation of the change(s)

Confirmation that the changes do not adversely affect the current design or safety function of the item.

Equivalency evaluations help determine the acceptability of the difference in the item to perform its safety function and identify critical characteristics for acceptance for the replacement item
