Cooper Relief Request-RP-06-MB6821 I had a telephone conversation with Ron Rogers of Cooper, 402-825-5304 this aftemoon( 3:30pm).
The following the summary of the discussion:
I tried to explain to him, in my own words, what I understand to be the staff's concerns.
I pointed out that there are following concerns:
a) On page 1 of 15, the submission states that Cooper wants to follow the normal test frequency to avoid subjecting the pumps to unneccessary wear, potential challenge to the plant, and entry into TS LCO...
BUT on page 4 of 15, It states that vibrations at these low frequencies should not be detrimental to either the pump or the motor...
These two arguments do not support each other I b) The submission does not provide any basis for presumption that the observed vibration levels historically have not been detrimental to the performance of the pumps nor would they detrimental to the performance of the pumps in the future( until next test).
c) The Variation in the vibration results need to be explained and the basis for raising the Alert Level' need to be provided in the submission This includes the basis for the Revised Alert Leval'.
d) My explainations are subject to corrections by the NRC staff.
Ron is going to talk to the appropriate person(s) In his organization and get back to me.
Further, teleconversations/Leleconferences may be needed.
John Huang, Please let me know If I have mis-understood the subject.
Thenks.
