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 potential of a catalyzed fusion-driven fast hybrid blanket to regenerate Canada deuterium uranium (CANDU) spent fuel is investigated. The investigations are done to achieve enrichment grades of fissile isotopes (EGFIs) in four applications: 1. recycling in a conventional commercial CANDU reactor (EGFI = 0.71 to 0.9%) 2. recycling in an advanced conceptual CANDU reactor with a high burnup rate (EGFI = 1%) 3. recycling in an advanced breeder with thorium fuel (EGFI > 1.5%) 4. recycling in a conventional light water reactor (LWR)(EGFI>3%). The regeneration periods of 5 to 7, 6 to 9, 12 to 15, and >30 months, respectively, are evaluated for the four reactor types under a first-wall fusion neutron current load of 1014(2.45-MeV n)/cm2-s and 1014(14.1-MeV n)/cm2-s, corresponding to 2.64 MW/m2 and a plant factor of 75%. During the regeneration process, the burnup rates vary from 2000 MWd/t (for conventional CANDU) to 10000 MWd/t (forLWRs), so that multiple recycling becomes possible.
