| 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). Advantages - 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. Applications - 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.
