Regarding system piping mitigation, does anyone use lancing/hydrolasing or mechanical vibration as planned scheduled items in outages to reduce whole line dose rate fields vs. just hotspots?
We are looking at performing one or both techniques on our condensate makeup lines to reduce rates from 7-10 mrem/hr to 1-2 mrem/hr, as this is a high traffic area for entry and exit. We were challenged in our scope meeting to see what the industry does. Chuck Creamer Charles E. Creamer Health Physicist Tennessee Valley Authority Browns Ferry Nuclear Plant P.O.
