e ATTACHMENT 1 REPLY TO A REQUEST FOR ADDITIONAL INFORMATION.
ON STATUS* OF*. CORRECTIVE ACTIONS FOR NRC BULLETIN 88-04 POTENTIAL SAFETY RELATED. PUMP LOSS I.
Corrective Actions -
- . Origin_aily Proposed Status -
. No corrective actions necessary. Engineering will initiate
. study to evaluate enhancements of cooldown and
- possible heatup operation which may reduce pump maintenance requirements.
COMPLETE
- II.
LOW HEAD SAFETY INJECTION (LHSI)
Corrective Actions -
-Originally Proposed Status -
- Small break LOCA scenarios will be conducted by November 1, 1988 on the simulator to verify the EOPs adequately address and therefore minimize o'peration of
- The LHSI pumps on the recirculation mode.
COMPLETE 111.
HIGH HEAD SAFETY INJECTION (HHSI)..
Corrective Actions -
No corrective actions* are deemed necessary.
- Originally Proposed Status. -
COMPLETE.*
IV. AUXILIARY FEED WATER (AFW)
Corrective Actions - Short Term Originally Proposed
. a.
- Appropriate_ procedur~s will be. reviewed and revised,* as necessary, by November 1, 1988 to minimize operation at' low flow/minimum flow recirculation.
. Status -
COMPLETE
- b. Operation/Engineering -personnel will be directed to limit: 1.JSe of.
these pumps in leak testing.
Status -
- COMPLETE
. \\ '
IV. AUXILIARY FEED WATER (continued)
Corrective Actions - Long Term Originally Proposed
- a. One auxiliary feedwater pump will be disassembled and inspected for degradation during the 1989 and 1990 refueling outage for each unit.
The remaining pumps will be inspected during subsequent outages.
Inspection results will determine the required inspection frequency and number of pumps inspected.
Status - INCOMPLETE. The Cycle 1 O refueling outages for Unit 1 and Unit 2 (the refueling outages originally referenced above) are currently scheduled for the fourth quarter on 1990 and second quarter of 1991, respectively, during which* this item will be initiated.
- b. Larger minimum flow recirculation lines are* scheduled to be.
installed in the 1989 and 1990 refueling outages for Units 1 and 2, respectively.
Status - INCOMPLETE. The Cycle 1 O refueling outages for Unit 1 and Unit 2 (the refueling outages originally referenced above) are currently* scheduled for the fourth quarter on 1990 and second
- quarter of 1991, respectively, during which this item will be completed.
