JANTI Guideline mitigation SCC ULBW
JANTI Guideline on underwater laser beam clad welding for preventive maintenance against SCC was published. This paper introduces the summary of that guideline. Underwater laser beam welding has good advantages for the repair and mitigation work for operating nuclear plants' reactor internals. Since it does not need to drain the water from RPV, preparation before the work can be very concise, and dose rate that workers suffer can be controlled in very low level. And heat input during the welding procedure ...

ambient temperature temper bead welding BWR PWR repair SCC underwater laser beam welding
It is known that stress corrosion cracking (SCC) might occur at the weld of a reactor pressure vessel or core internals. Underwater laser beam clad welding for mitigation of SCC has been already established and the guideline “Underwater laser beam clad welding” was published. Moreover, the guideline “Seal welding” was also published as a repair method for SCC. In addition to these guidelines, the guideline “Underwater laser beam repair welding” was newly published in November, 2012 for the repair weldi...
