Schulz Electric™ Refurbishes Critical Circulating Water Pump Motor in Only Four Days
Schulz Electric™ was contacted by a nuclear power plant in the New England region that serves a community of over 2 million homes. After five years of service, a 1500 HP, 4 kV, 24-pole circulating water pump motor (measuring approximately 7’ wide, 8’ tall, and weighing several tons) needed refurbishing while the plant was still online. To add to their concern, the power plant is located close to the ocean. The aging motor was not only approaching the end of its serviceable life, but was highly susceptible to moisture intrusion and the salt-laden air, which can build up in air passages within the motor. These environmental conditions can lead to elevated operating temperatures and corrosion developing on the rotor, stator, and shaft components. These factors combined, placed the plant at an increased risk of downtime that could have potentially led to a significant loss of revenue if they were forced into a shutdown event.

The Tritium Systems Test Assembly (TSTA) has been operating for 4 years with tritium inventories of up to a million Ci and a cumulative (circulated) throughput of over 10 billion Ci to date. During the operational life of the facility 40,000 Ci of HTO waste have been intercepted by the tritium waste treatment system. Stack releases for the 4-year period have totaled < 40 Ci, and exposure to operating personnel has been < 3 mREM/person/yr. This excellect record is due in large part to high priorities placed on tritium-safe design concepts, but real-time computer diagnostics have been equally important in enabling us to anticipate and prevent potential releases of tritium.This work is supported by the US Department of Energy, Office of Fusion Energy.
