Nuclear Power Plant Selects Motivair Mission Critical Chillers

Motivair Corporation, based in Buffalo, New York, a global leader in Mission Critical Chillers and Cooling Systems announced completion of a large scale Nuclear Chiller Plant replacement project at the Donald C. Cook Nuclear Power Generation Station located in Lake Township, Michigan, USA.  Ten (10), water cooled, Low Temperature Process Chillers were installed to replace original equipment that had reached end of life.

A nuclear reactor’s Cooling System is paramount to safe operation of a nuclear power plant. With original water-cooled Westinghouse chillers operating beyond their 30-year life expectancy, a chiller replacement project became top priority for the DC Cook Nuclear Plant.

The project goals were demanding as expected from a Nuclear Plant. The new Motivair chillers had to be designed to match the original equipment footprint and the chilled water inlet and outlet connection locations needed to match exactly, thus minimizing any seismic re-certification of existing chilled water piping in the facility. Each chiller required extensive, individual capacity performance testing, client witness testing and 3rd party seismic testing.

Each water cooled chiller was capacity rated to produce 25 tons (88kW) of net cooling, making glycol for DC Cook at -5°F (-20.5°C).  On an expedited schedule, Motivair completed all design, manufacturing and performance testing on time for a successful project.
