Castrol Nucleol G121 - Radiation Resistant Grease - 2351
Castrol Nucleol G121 is a radiation resistant grease based upon a high viscosity mineral oil with an inorganic thickener system, which gives outstanding thermal and radiation stability. Castrol Nucleol G121 also provides a high level of corrosion protection for components exposed to hostile environments.
Due to the high viscosity of the base oil of Nucleol G121 it gives good performance in low speed bearings but is not suitable for use at moderate or high speeds. Nucleol G121 is ideally suited for the lubrication of control rod mechanisms. Nucleol G121 comfortably exceeds the UKAEA Schedule I requirements for radiation resistance and is fully approved for use within nuclear installations.
Nucleol G121 meets the Schedule I volatility limit of 4% after 400 hrs at 150ºC with CO2 flow of 1 litre/min.
