Victor Stello, Jr.
Executive Director for Operstier.s FROM:
James K. Asselstine -
1-I m
SUBJECT:
SURRY PIPE BREAK t
The March 12, 1987 edibon ~of Nucleonics Week contains an article on the French research program on secondary pipewaTT thinning (p. 2). That article states tiat the French " initiated a 'very thorough' investigation of corrosion-erosion a few years ago in connection with thinning in walls
- of J-tubes injecting steam generator coolant."
! would appreciate a brief 4
} description of how we are approat.hing the possible problem of corrosion-erosion in feedrings and J-tubes.
In addition, I would like to know the rationale for not citing VEPC0 for failure to comply with GOC-1 in that the corrosion-erosion phenomena persisted undetected to the point that there was a catastrophic pipe rupture.
