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.

An experimental apparatus has been developed to carry out tritium permeation experiments for candidate first-wall materials subjected to a high flux of low energy tritium ions, and installed in a glovebox. The experimental apparatus consists of five main systems; (1) a tritium ion source with energies variable from 20 to 1400 eV, (2) a main chamber system for directing an ion beam onto a heated target and for measuring various implantation-related experimental parameters by means of SIMS and AES, (3) a downstream system for measuring the permeated tritium through the target specimen by means of QMS, (4) a tritium supply and recovery system and (5) evacuation system. Operational tests with the system have yielded deuterium ion-beam with more than 90% deuterons and intensities from 2x1015 D+/cm2s at 200 eV to greater than 3x1015 D+/cm2s at 1000 eV. The energy width of the ion beam was about 10% of the beam energy ranging from 100 to 1400 eV. Baseline pressure as low as 9x10−9 Torr and 1x10−9 Torr have been achieved in the main chamber and downstream system, respectively.
