Code Requirements: If leakage occurs at a bolted connection, the bolting shall be removed, VT-3 visually examined for corrosion, and evaluated in accordance with IWA-3100. (IWA-5250(a)(2) Corrective Measures)
Alternative Testing: If leakage occurs at a bolted connection, during the performance of a :

REllEF REQUEST Basis for Relief: Current Code requirement specifies that all bolting must be removed Q in the event of a bolted connection leak for the purpose of VT-3 examination and evaluation. This would require placing the associated component or portion of piping out of service possibly resulting in a plant shutdown, delaying plant startup, or placing the plant in an unsafe condition for continued operation, as all VT-2 examinations are preferably performed at nominal operating n
