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.

Activation analysis was performed for the outboard (o/b) and inboard (i/b) blanket and shield of ITER. The options of using PCA or Tenelon were assessed. The o/b blanket and shield qualify as class C LLW. If Tenelon is used, it qualifies as class A waste. The i/b shield by itself qualifies as class C waste only if Tenelon is used. If PCA is used, then class C qualification can be realized if the i/b and o/b shields are disposed of together. The total amount of 14C produced in the coolant is 4650 Ci for LiNO3 and 54 Ci for LiOH. The Be/SS/W i/b shield results in a decay heat much less than that in an all W shield. Under adiabatic heat-up conditions, the PCA structure can withstand a L0CA and after one day the temperatures do no exceed 700°C.
