Obsolescence Solutions

Obsolescence is one of the most challenging issues facing the nuclear power industry today. Failure of an obsolete part can lead to a number of problems such as extended outages, loss of revenue and greater operating costs. Having a proactive strategy in place will help a plant avoid having to do costly maintenance and repairs because a part is not available. Utilities have recognized seven types of solutions to the obsolescence issues ranging in first time cost, complexity, and permanence.

Regardless of which type of solution best meets your needs, Curtiss-Wright Nuclear’s brands Enertech, Scientech, Qualtech NP, and Nova can offer a best fit solution.

Curtiss-Wright Nuclear brands combined can meet whatever obsolescence solution type you prefer. Curtiss-Wright Nuclear’s Enertech brand in particular specializes in four of these obsolescence solution paths:

Special Manufacturing Runs

Enertech has established manufacturing license agreements with critical suppliers that have retired nuclear quality assurance programs. These license agreements enable the purchase of genuine OEM parts with all the necessary qualifications and certifications. Enertech has obtained intellectual property rights for various obsolete nuclear products and is also an expert at “build to print” manufacturing. In addition many of our partners who still have their nuclear quality assurance programs still support some of their obsolete components through special manufacturing runs.

Rebuild RepairRebuild/Repair

Enertech offers field service engineers and technicians for the repair, rebuild, and remanufacturing of obsolete valves, pumps, heat exchangers, and instrumentation either onsite or at one of our local qualified service centers.


Enertech has an extensive experience working with utilities to upgrade obsolete components to the most current model while still maintaining all form, fit, and function requirements. By providing this value added service, Enertech is able to help plants minimize modification costs.

Design Change

Enertech has an extensive portfolio of advanced valves, actuators, pumps, heat exchangers, and digital instrumentation to help eliminate reoccurring maintenance and enhance overall equipment reliability. Our design and application engineers will to support these complex projects to ensure the scope of the modification is minimized while maximizing the improvement in equipment reliability.
