Abstract

This report contains the description of the test conditions, procedures, and main results of the following types of mechanical tests of unirradiated and irradiated Zr-1% Nb cladding:

• biaxial burst tests with liquid pressurized tube specimens in the temperature range 293–723 K;
• uniaxial tensile tests in axial direction with tube specimens in the temperature range 293–1200 K.

Results of these tests are compared with test results obtained in 1997–1999 using simple ring specimens (293–1200 K) and gas pressurized tube specimens (900–1400 K).
