The Widest Selection
Of World-Class Motors
For Nuclear Applications
For over 90 years, the Reliance brand name has been
synonymous with reliability. Reliance nuclear motor designs
have been field-proven around the world in commercial nuclear
utilities and radioactive waste facilities with the most stringent
requirements. Our nuclear motors have proven themselves in
type test after type test.
As a leading global manufacturer of high-quality motors, Baldor
offers the widest selection of nuclear motors available from a
single source. Our product line encompasses over 250,000
ratings, types, styles, and sizes – from fractional through
15,000 HP – including AC motors designed to run with the most
advanced adjustable speed technology.
In addition to continuous-duty, three-phase, squirrel-cage AC
induction motors, we offer a full range of specialty motors and
specialized construction features, including:
•
•
•
•
Intermittent duty
Vertical hollow shaft (Above NEMA)
Specialized mounting
NEMA Premium® Efficiency electrical designs
Our capabilities extend to researching and developing
customized design solutions for critical applications. From
standardized to highly-engineered motors, we offer solutions for
virtually every ¼ HP to 15,000 HP nuclear motor requirement.
There are Reliance-brand nuclear motors driving pumps, fans,
compressors, and motorized valve actuators in nuclear power
plants across the United States, Canada, Europe, and Asia.
Also, Reliance nuclear motors support industrial operations,
such as nuclear waste cleanup and nuclear fuel reprocessing
procedures. When you chose Reliance nuclear motors, you
can be sure that every motor component, from the motor
hardware to the rotor and stator, will be 100% in compliance
with your specification and the requirements of the IEEE and
NUREG standards governing nuclear power plants.
Our nuclear motors are designed and manufactured to meet
the specific requirements of your environment, including:

Other Application-Specific Requirements
Mild Environment Motors
Reliance nuclear motors are designed to meet the specific
requirements found in specifications developed by nuclear
power plants and nuclear fuel reprocessing facilities. Each
specification is reviewed to determine normal and extraordinary
operating and environmental conditions, radiation exposure
levels, and LOCA (Loss of Coolant Accident) or other incident
environments. This information is provided to Design
Engineering to insure that the motor for the specific application
is sized and designed to meet all of the environmental and
operating conditions over the qualified life (40 years in most
power plants) of the motor.
Baldor offers a line of Class 1E motors in NEMA and most
IEC frame sizes that meet the IEEE 334-1994 definition for
a Mild Environment Product, with a total integrated radiation
dosage of < 1 X 104 Rads over a 40-year Design Life. These
motors have a Class H insulation system with VPI encapsulated
windings for extended thermal life. Standard features include
Severe Duty construction, Neoprene gaskets and seals, and
a non-metallic, low-loss fan design to reduce friction and
windage losses. A wide range of modifications and accessories
are available.
When required, Seismic Response Data and Curves are
provided by the nuclear facility to enable Engineering to
mechanically design a motor that will withstand the earthquake
stresses that the facility may be subject to. A Seismic Analysis,
either static or dynamic, is then performed to determine that
the design will meet the specified requirements. The analysis
performed meets the requirements of IEEE 344-1975, 1987.
These motors are completely manufactured and tested under
our 10CFR50, Appendix B Nuclear QA program. Available
software documents include a Seismic Analysis, Certificate of
Compliance, Routine Test Report, and a Mild Environmental
Qualification (EQ) Report.
Harsh Environment Motors
Reliance nuclear insulation systems, both the type H/RH
random wound and the F-RBI form wound systems, have been
qualified by rigorous accelerated life testing under severe
high temperature conditions, high humidity tests, accelerated
radiation endurance testing, and mechanical stress testing.
These qualification tests were conducted on both “motorette”
components and on complete motors. Based on the results
of this testing, both of these insulation systems are qualified
for a total integrated radiation dosage of up to 2 X 108 Rads
over a 40-year life, with a 60-year life at reduced operating
temperatures.
It is the performance and results of this testing that form
the basis for the Environmental Qualification Report that is
prepared and submitted with each Class 1E Safety-Related
nuclear motor.

Quality Control Checklist for Nuclear Motors
• All critical components are 100% inspected and
dimensionally checked against parts drawings, with all
measurements recorded.
• Samples of all materials such as wire, insulation, and
fasteners are destructively tested.
• Every manufacturing step is verified and recorded.
• Processes such as dip and bake and VPI are qualitycontrolled.
• Resins and varnishes are tested daily or before each
application.
• Ovens are calibrated, with baking times and temperatures
recorded.
