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 analysis of an l = 2 torsatron with a relatively small pitch angle of the helical winding, which requires an additional toroidal field (TF), is presented. The main advantage of this torsatron design, as compared with a conventional torsatron having a large helical winding pitch angle and no TF coils, is the reduction of the helical winding current and the helical ripple of the magnetic field. This facilitates construction and operation of the most complicated component of the magnetic system, the helical winding, and also reduces the plasma losses due to magnetic field ripple. An experimental device of this type, URAGAN-2M, now under construction at the Kharkov Institute of Physics and Technology, is described. The reactor prospects of this concept are also discussed.
