o ATTACHMENT LCR 95-05, Supplement 1 Restated below are the NRC staff questions raised during the May 19,1995 conference call followed by the PECO Energy response.
NRC Ouestion 1:
What type of packing is used in MO-2-23-157 Has it been upgreded?
PECO Energy Response: Modification 1909, which was performed in November 1988, upgraded the packing material from asbestor tr. graphite.
NRC Ouestion 2:
Describe the procedure used by PECO Energy to cackses' MO 2-23-15.
PECO Energy Response: The procedure used to backseat MO-2-23-15 is as follows:
- 1) the valve is opened from the control room to its normal full open position; 2) the open limit switch is jumpered to allow additional travel in the open position; 3) the valve operator motor is momentarily energized (for a predetermined amount of time) allowing inertia to coast the stem into the backseat.
NRC Ouestion 3:
Did PECO Energy considered GE SIL-385 while performing the backseating of MO-2-23-15.
PECO Energy Response: The guidance provided in GE SIL 385 was reviewed and appropriately applied prior to backseating MO-2-23-15.
The backseating procedure as described above prevented overstressing and damage to valve components.
MO-2 23-15 is not a normally backseated valve. It is only backseated on an as needed basis using administrative controls which ensures that an evaluation and analysis is performed prior to backseating.
The valve manufacturer was contacted prior to backseating MO-2-23-15 for information and alternatives.
