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.

A simple fusion experiment for the production and control of deuterium-tritium-ignited plasmas for scientific study is considered. The basic elements of fusion product alpha-particle behavior at ignition are analyzed. Alpha-particle containment is rather high even with the assumption of significant levels of toroidal asymmetries. Production of thermally stable plasmas is possible because of the low-beta thermal damping provided by electron cyclotron emission. The stability of internal kink modes, high-number ballooning modes, and toroidicity-induced shear Alfvén eigenmodes is investigated in the presence of fusion alpha particles. These modes can be either stable or unstable depending on the selected operational regime at ignition.
