C-E in-Containment Nuclear Pressure Transmitter: A Qualification Status Report

Qualifying a piece of equipment for a Class IE incontainment nuclear application is a complex process. First the equipment must be "aged" to simulate a predetermined installed life in a way that is demonstrated to be realistic. Then it must be seismically and environmentally tested to conditions that envelop those that may occur in the design basis accidents. Once thi s process is complete, the equipment is said to be "qualified" for the duration of its installed life to operate properly during normal operation and accidents that are no more severe than the test conditions. The above statement is true only if the equipment is installed, interfaced, and operated consistent with the conditions under which the qualification was performed.
