Creep & Stress Rupture Testing Services for the Nuclear Industry
Creep and rupture tests are utilised to evaluate and predict the time-dependent behaviour of materials at elevated temperatures under applied stress in tensile or compression. Deformation is measured as a function of time.
Understanding material properties is essential for designing nuclear safety-related components and systems used during processing, transport, and storage.
We can use this data to:
- Develop advanced materials that are fit for purpose
- Develop operating limits for existing materials in new environments
- Predict how joining techniques will perform under real-life conditions
- Estimate service life
- Develop maintenance schedules and reduce the risk of catastrophic failures of equipment under high-temperature and stress conditions
Lucideon has 22 creep / stress rupture test stands available, that can test specimens up to 10-1/8" in length ranging from carbon steel alloys and stainless steels to Inconel alloys. Tests may be conducted up to 1650°F in temperature and 10,000 lbs in load. Temperature and creep readings are recorded and monitored continuously to ensure accuracy of results.

Lucideon has developed geopolymer formulations for diverse applications and has built the understanding to control important characteristics
A geopolymer formulation characterized by a low initial viscosity, suitable to immobilise a wide range of waste types such as oils, chemicals and solid waste, is introduced and characterised
