TEXTO
(*)Motor Control Centers (MCCs) are vital to the operation and control of nuclear power plants. A
significant and growing problem within the global nuclear industry is the aging of MCC components.
Obsolescence of various components within the MCCs such as molded case circuit breakers, starters, relays,
heaters, transformers, etc. are impacting the reliability of MCC to perform their intended safety function.
(**)Many OEMs have sold off product lines, discontinued vintage products or merged with other companies.
This has complicated the procurement of replacement parts needed to maintain reliability of MCCs. The
combination of aging installed equipment, component obsolescence and surveillance testing is forcing many
plants to aggressively address MCC refurbishments or face unplanned outages due to unavailability of critical
motors.
(***) Companies such as NLI offer replacements for most legacy MCCs. NLI has supplied thousands of
MCC replacement cubicles for ITE 5600 Series, GE 7700 Series, Westinghouse Type W Series, Cutler
Hammer F-10, 9800 Series, Cutler-Hammer DC cubicles, as well as many other vintage OEM styles.
Replacement requires identification of suitable available components, design drawings, layout design,
dedication, qualification and fabrication. Many components—and in some cases entire motor control
centers—are no longer available or not supported by the OEM.
Due to extreme degraded voltage requirements at many plants, modifying starters with custom coils designed
coils is required, NLI has been doing this for over 10 years. This potentially saves plants millions of dollars
in calculations and modifications. Few companies possess the technical expertise to accomplish this
modification.
Replacement cubicles are not the only answer to the obsolescence issue, offering a variety of MCC services
from full replacement to refurbishment of existing components are additional solutions. Retrofiting existing
MCCs by replacing stabs, latches, and structural components for better seismic rigidity are examples of
refurbishment of existing MCC’s.
