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.

Neutron spectrum measurement based on the foil activation technique was carried out as a part of the JAERI/USDOE collaborative program on fusion blanket neutronics. The adequacy of the foil activation technique and the current dosimetry nuclear data for the D-T fusion neutron field were examined through the analysis of the spectrum in a Li2O blanket system enclosed with the Li2CO3. A method using a pair of activation indices (MPI) is newly proposed to evaluate the neutron flux around the MeV region of interest in a qualitative way. The multi-foil activation technique (MFA) with proper detector cross section data are promising to determine neutron spectra over a wide energy range.
