Mechanical Properties of Some Candidate Glasses for High-Level Radioactive Waste Management

摘要

The biaxial flexure fracture stress, fracture toughness and Young's modulus were measured for different nuclear glass compositions. The KIC values of all the nuclear glasses tested ranged from 0.90 to 1.10 MPa.msup(1/2), slightly higher than for Pyrex. Crystallization and incorporation of simulated metallic fines had no detrimental effect. (ERA citation 09:009459)
