Researchers at Purdue University have developed a versatile mechanical testing device for in-reactor (nuclear reactor) testing. This rig can test a variety of creep and tensile specimen geometries and is designed to operate in the harsh environment of in-situ reactor testing. The device has a modular design, which allows it to hold and test a variety of specimen geometries. The mechanical properties of creep and tension are crucial for validating material performance in a reactor. Additionally, this design can also be used outside of a reactor. The compact grip design is suitable for testing sub-sized specimens in small apparatuses, such as in-situ creep capsules. It eliminates high stresses in unwanted areas (which is a problem with traditional grip designs) and allocates the stresses in the gauge length of the specimen (a new feature of this grip design).

- Directs stresses along gauge length.
- Capable of in-reactor testing for a variety of sub-sized specimen geometries
- Compact enough to fit in small test apparatuses.

- Sub-size tensile/creep testing
- In-reactor testing
- Power plants
- Engine control systems
- Spacecrafts (re-entry)

Technology Validation:
This technology has been validated through fabrication and testing of a prototype.
