Dear Dr. Murley:
The' following is an update to our initial response to I/E j
As a result of recent reactor cavity seal testing performed at IMPELL Corporation on 2/7/85 and 2/8/85, it was determined that seal deflection ~ measurements, as proposed in our initial response to Bulletin 84-03, would prove inconclusive.
During the i
testing, it was observed that final seating of the' cavity seal does not occur until a significant head of water- ~(approx. ten feet)
~
covers the cavity seal.
This observation was discussed with Mr. Lee Bettenhausen and Mr. Henry VanKessel of NRC Region I.
It was agreed that Rochester Gas and= Electric would attempt to obtain vertical offset measurements as requested by Mr. VanKessel instead of the seal deflection measurements.
This was contingent upon acceptable. radiological dose rates '(in the work area).
These measurements were subsequently obtained with the results indicating less than a 1/4" offset existed between the reactor vessel flange and the refueling cavity.
A copy of the test matrix and the experimental results
.obtained from the IMPELL test have been transmitted'to Mr. VanKessel.
If any further information is necessary, please contact-Mr. Joseph Widay at the R.E. Ginna Plant.
Please -consider this as our final closeout to I/E Bulletin j
84-03 i
V truly yours,-
