QualTech NP provides nuclear grade spare parts for equipment used in nuclear power applications. Many OEMs have discounted support of their installed base of safety-related parts. We have qualified over 25,000 commercial-grade equivalents with the same form, fit and function as the original part.  Our vast array of qualified products covers virtually every plant need, whether the part is large or small; electrical, I&C or mechanical; “one of” or “many of”.  Examples of our qualifications include: circuit breakers transmitters, electronic modules, actuators, battery chargers, and motors.

QualTech NP maintains a searchable data base of qualified parts: 

QualTech NP maintains two test facilities, one in Cincinnati, OH and on Huntsville, AL, where CGD is performed.  Our NUPIC-audited facilities qualify equipment in accordance with EPRI  NP5652, IEEE 323 and IEEE 344. QualTech NP has extensive experience in providing CGD services. Working with your team our engineers determine qualification and testing requirements and then submitted a dedication plan for your acceptance. On completion of the dedication process, a final report and all required documentation are submitted to you per your purchase order.
