The accumulation of deposits in the secondary side of steam generators (SGs) increases the potential for accelerated tube degradation and flow oscillations. As these deposits harden and form crevices, they can cause conditions that lead to tube corrosion. To improve upon traditional mechanical deposit removal techniques and avoid the potential drawbacks of traditional SG chemical cleaning, advanced scale conditioning agent (ASCA) technology was developed in 2000.

Reliable and proper overhead crane performance is important to ensure personnel safety, nuclear safety, and the protection of important assets such as the reactor vessel internals, the reactor pressure vessel (RPV) head, fuel assemblies, and dry fuel storage casks.

"Irradiation assisted stress corrosion cracking of reactor vessel internals is an important consideration as nuclear plants reach extended lifetimes. One component that is critical to maintaining the structural integrity of the internals and that has been shown to be susceptible to aging mechanisms is the baffle-to-former bolts (or baffle bolts)."

Westinghouse, through its subsidiary WesDyne International, provides nondestructive examination (NDE) services and inspection equipment for both the nuclear and non-nuclear power generation industries.

The oil level indicating system on Westinghouse reactor coolant pump (RCP) motors monitors the oil inventory within the bearing oil reservoir. The concept behind the original system used on the lower oil reservoir on RCP motors was a simple transference of oil level from inside the bearing oil reservoir to an alarm reservoir and sight glass that is external to the lower oil reservoir.

Reactor coolant pump (RCP) control leak-off seal performance is heavily influenced by a variety of plant and environmental conditions that can directly impact the RCP seal leak-off rate, the dominant variable used to evaluate seal performance. Unplanned forced outages or an extension of an outage can result if leak-off rates approach their lower or higher operating limits.

Operators of Pressurized Water Reactors (PWRs) with reactor vessel (RV) nozzle dissimilar metal (DM) safe-end welds, which are susceptible to primary water stress corrosion cracking, are required to examine those welds with increased frequency unless mitigating actions are taken. Requirements for these examinations are specified in American Society of Mechanical Engineers (ASME) Section XI, Code Case N-770 latest approved revision specified in 10CFR50.55a.

In 2010, an international plant was shut down due to primary coolant leakage from a serviceinduced crack in a deformed pressurizer heater well insert (HWI). Intergranular stress corrosion cracking had initiated on the outside diameter surfaces of the heater sheaths, allowing primary water to enter the heater elements. The primary water then reacted with the magnesium oxide insulation inside of the heater internals, resulting in volume increase and subsequent splitting of the heater sheaths and HWIs.

Solving corrosion-related issues is a major challenge for the worldwide ageing fleet of nuclear power plants, looking for LTO (long-term operation). While utilities can proceed to replacements for many pipes affected by corrosion, a replacement strategy is not always possible. Other maintenance solutions are required for inaccessible or embedded pipes. Moreover, for those pipes which cannot be replaced, internal inspection and corrosion removal become an even greater technical challenge if the pipe’s diameter is small and when the remote access to the zone of interest requires to travel through bended sections and elbows.

Socket welds are used in numerous applications throughout the nuclear industry and due to the unique configuration, size and other limitations, ultrasonic inspection can be challenging. Westinghouse Inspection Services has the equipment, qualifications, and personnel to perform socket weld inspections for the thermal and vibration fatigue degradation mechanism. Even a slight stress flaw is detectable with the help of Westinghouse’s experience and advanced technology.

Over decades of operation, foreign material accumulates under the spent fuel pool storage racks, creating increased dose rates and operational challenges. This material can be in the form of particulate/sludge like material as well as foreign objects. Foreign material can be disturbed by water motion caused by fuel handling and spent fuel pool filtration. Water disturbance affects pool clarity and visibility, increasing the potential for human performance issues, schedule delays, and fuel damage.
