Obsolete Parts

Obsolescence and the ability to obtain qualified replacement and spare parts are primary concerns in the nuclear industry. As your partner, Westinghouse would like to make you aware of an imminent obsolescence challenge that could impact your plant.

Out with the old and in with the new. It’s a familiar adage, but one that has profound connection to today’s “throw-away” society. From electronics to automobiles to appliances, we are focused on obtaining new rather than fixing old. However, in a highly regulated industry, that doesn’t always apply.

Nuclear plants consist of many components, which are thoroughly tested and inspected to ensure they can perform required functions. As nuclear power plants are reaching 50-year milestones on their way to lifespans of 80 years, components that are no long manufactured or qualified to the current regulated standards or are no longer available from the original manufacturers need to be replaced. Testing new parts can be done, but sometimes at a significant cost. 

At Westinghouse, Nuclear Parts Operations (NPO) plays a vital role in maintaining the critical assets of our customers and in helping to ensure safety and reliability through the high-quality spare and replacement parts, component repair services and equipment upgrades we provide.

See below to learn more about obsolescence issues that could impact your plant.

Gemco Switches

A number of nuclear power plant control rooms were outfitted with Gemco® Series 404 rotary selector switches as part of the original design.

Westinghouse has engineered a switch to replace the now-obsolete Gemco switch which will also perform longer and more reliably than the original. Furthermore, replacing the original Gemco switches with the new will minimize the potential for any failures during the life of the original Gemco switch assemblies.

HFB and MCP molded case circuit breakers

HFB and MCP molded case circuit breakers are used in motor control centers and a vast majority of circuit protection applications. The current manufacturer of these specific breakers will stop accepting orders on Jan. 1, 2018.

Since alternate replacements for the 10 Amp HFB1010, HFB2010 or HFB3010 do not exist, we urgently recommend acquiring any breakers in this category in sufficient quantity to allow for reliable plant operation.

In the spirit of Delivering on the Nuclear Promise, we are also offering a discount on all of these HFB circuit breakers.

Please contact your nuclear parts specialist for more information.
