For the PT examinations, Holtec stated that they have been performing the hydrostatic test first and followed by PT weld examinations, and there has never been any issue with the post-pressure PT weld examinations. Almost 2,000 systems have been load and the hydrostatic test performed on the MPC, in which more than 1,000 are HI-STORM 100 system and more than 250 are FW system.
