Integrity evaluations have been performed for the 2nd Fugen pressure tube test (8 years irradiation, 5.6 10 $^{21}$ n/cm $^{2}$ (E1Mev)). Test items mainly consist of tensile test, bending test, corrosion test and hydrogen analysis. It has become clear using these data that the pressure tube material has maintained its integrity during the irradiation by the integrity assessment on both tensile and fracture toughness properties. Besides, both thickness loss by corrosion and absorbed hydrogen content were lower than those of design values.
