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 L–mode scaling law of global energy confinement time in ion cyclotron resonance heating (ICRH) is proposed in this paper. The scaling is based on 292 observations from tokamaks PLT, JET, ASDEX, TEXTOR, JFT–2M and JIPP T–IIU. The regression analysis reveals the scaling being of the form: τE α a-0·18 R1·27 IP0·98 BT0·10 K0·20 n̄e0·12 Ptot-0·51. Comparision with other scaling laws and fitting the scaling law to the theoretical constraint model have shown many physical phenomena of ICRH wave damping mechanism. To reach the ignition condition, some modifications of experimental technique and tokamak configuration are needed to enhance the energy confinement time.
