HRC BULLETIN 87-01, "THINNING 0F PIPE WALLS AT NUCLEAR POWER PLANTS" L

On July 9, 1987, NRC Bulletin 87-01 was issued and requested that licensees submit information concerning their programs for monitoring the thickness of pipe walls in high-energy single-phase and two-phase carbon steel piping systems. The Baltimore Gas and Electric Company provided its response to the Bulletin in a letter dated September 9,1987.

The information that you provided is being used to determine the extent of industry participation and implementation of erosion / corrosion inspection programs, and to obtain data on obs!rved pipe wall thinning. The staff does not plan to determine the adequacy or the acceptability of your current program at this time.

As such, no further plant specific action with respect to NRCB 87-01 is required.

You will be notified should there be any further action that may be required regarding the subject of Pipe Wall Thinning.

Sincerely, pristual signi,e ty:
