DCrutchfield RE:
REACTOR CNITY SEAL RING. GENERIC ISSUE (PAR)
Me have completed our review of your response to our letter of February 2, 1978, in regard to the potential for the reactor cavity annulus seal ring to become a destructive missile in the event of a loss-of-coolant accident
.pipe break inside the reactor cavity.
1 Your response acceptably resolves this issue for R. E. Ginna Nuclear Power Pl ant.
Sincerely, Ornal
