Precision lubrication in nuclear
As the global nuclear sector turns towards ramping up the supply chain the important role of lubrication in optimising manufacturing and operation of nuclear-specific components like large forgings or the use of exotic metals cannot be over-estimated
Mel Kohl, Founder, CEO and President of Consultant Lubricants
BECAUSE OF THE EXTREME CONDITIONS of nuclear systems, precision and reliability are of the utmost importance. The large forgings and exotic metals used in nuclear manufacturing are exposed to high temperatures, stress, corrosion, and irradiation, making precision lubrication essential to their performance and durability. Precision lubrication involves using the correct type,
quality, and quantity of lubricant for machinery or other equipment, as well as lubricating the correct component in the appropriate place at the right time. The main purpose of precision lubrication is to enhance the reliability and efficiency of equipment, thus reducing the rate of wear and production downtime. Precision lubrication is particularly important in nuclear manufacturing that uses large forgings and exotic metals because of the extreme stress and environmental conditions they endure. Precision lubrication
plays a key role in: ● Reducing wear and tear on components ● Minimizing friction ● Enhancing corrosion resistance ● Extending the lifespan of machinery and its components ● Ensuring the safety and reliability of nuclear systems
Choosing a suitable, high-quality lubricant – such as the Consultant Lubricants graphite-based 7221 hot forging compound – and using appropriate methods of application are both crucial considerations. The most common lubricant type is R&O (rust
and oxidation) oil, used primarily in many light-duty conventional and nuclear applications. The second most common type is hydraulic fluid with anti-wear additives, which is used where there is a requirement for preventing asperity-to-asperity contact during mixed or occasional boundary lubrication. The third most common type is gear oil, which is used in most gearboxes and actuators. Other oils include compressor oils, turbine oils and transformer fluids. Typical greases used include polyurea, calcium sulfonate, and lithium complex. Another important consideration in respect of lubrication
is the role of continuous training and skill development for engineers and technicians. They are crucial for ensuring effective lubrication practices. Specialised training programmes focused on lubrication in nuclear environments are essential. These programmes ensure that personnel are well-versed in the latest lubrication
