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 measurement of 14-MeV neutron multiplication is given for a 4-cm-thick thoria assembly in rectangular geometry. This agrees within 2% of the corresponding calculated value of neutron multiplication obtained by using the general geometry Monte Carlo code MORSE-E and the Los Alamos National Laboratory 30-group neutron cross-section set Claw-IV in P3 scattering approximation. The results confirm Kushneriuk and Wong's calculational analysis of the Shief et al. experiment with a large cylindrical thorium metal assembly using the ENDF/B-IV library, as well as Kobayashi et al. 's differential neutron spectrum measurements in a spherical thoria pile and thorium metal slab by the time-of-flight method.
