Weld repair of Heavy Section Steel Technology program vessel V-7. Final report
The Heavy Section Steel Technology (HSST) Program by ORNL and sponsored by the NRC has been pressure-testing intermediate sized vessels roughly scaled to nuclear reactor pressure vessels. One such vessel, ITV-7, intentionally flawed in the axial direction, was hydraulically pressurized to failure--leakage occurred when the vessel was pressurized to 2/sup 1///sub 2/ times the design pressure. Arrangements were made with the HSST Program Office to use this vessel for the purpose of repairing the thru wall flaw according to Section XI procedures. The repair was performed to demonstrate the utility of such a weld repair. The report documents details of the procedures used with that repair.
