RE: Inspection of Sand Bed Drain Lines I am responding to my action item from Dave Ryan that this is not a commitment, but must remain in scope for the outage.

li' discuss with Don and John 0' during turn over. I also think it is a good idea to look at the drains and sandbed floor for debris that could get into the drains when the coating in the bays with drains is inspected. It is not a commitment to check the drains; but we would not look good if weflood the sandbed because the drains are plugged

RE: Inspection of Sand Bed Drain Lines With regard to the suggested Check of the configuration, suggest that we agree on the change and have the KS program engineer issue a revision to the appropriate recurring task(s) to implement the requirement.

RE: Inspection of.Sand Bed Drain Lines I agree with your assessment. I also reviewed the June 20, 2006 letter which responded to NRC concerns outlined in the June 1 Public meeting, and as expected, found no commitment to inspect the sand bed drain lines for blockage.
As a separate but related point, do we have a recurring task to ensure that the tubing that goes from the sand bed drain to the poly bottles is intact? It seems we should verify the integrity of this configuration on some regular interval, even if it is not a commitment.

Inspection of Sand Bed Drain Lines John, Please confirm the following conclusion relative to the sand bed drain line inspection. This is needed to satisfy an action item I received from an outage planning meeting this week. Thanks.
-Conclusion: It appears the inspection of the sand bed drain lines for blockage is not currently a commitment.
This is based on my review of the current A.5 table~of commitments, review of the July 7, 2006 letter to the NRC, and discussions with Ahmed Ouaou. Examination of the trough drain for blockage is a commitment and is contained in our table of commitments and is specifically listed in the July 7, 2006 letter. I have attached a copy of the letter for your reference if needed.

Subject:
DEBRIS LOCATED IN BAYS 7 AND 11 SANDBED DRAIN LINES
==
Description:==
Originator: PETER TAMBURRO Supv Contacted: Howie Ray Condition
Description:
Inspection of the Sandbed Drain Lines in accordance with Specification 1S-328227-004 Rev. 13 showed that the drain line in bay 7 has debris, which could cause blockage of this line. The debris looks like loose concrete. This does not meet the acceptance criteria in the specification per section 3.2.5.2.
In addition the inspection of the drain line in bay 11 shows some loose debris in the bottom of the line directly downstream of the first elbow.
However the line is not blocked and meets the acceptance criteria.
Operability The purpose of the drain lines is to route.water in the sandbed from the drywell vessel. At this time the remaining 4 lines are capable of,
performing this function. In addition since the line In bay 7 is not completely blocked it too would partially perform Its function by draining th~e sandbed. So far in 1R21 no water has entered the sandbed.
Engineering has inspected the 5 bottles every day since the beginning of the outage (R2088495). To date no water has been found in any of the bottles or on the floor outside, the sandbed bays.
Also Engineering and/or NDE have Inspected all 10 Drywell Sandbed bays. To date no water or moisture has been observed in these bays and the coating is in good condition..
Engineering will continue to monitor (on a daily basis) the trough drain line for changes in flow rate and the five polyvinyl bottles for water, Immediate actions taken:
Informed Howie Ray and the Engineering Control Center Recommended Actions:
- 1) Continue to monitor the five poly bottles and trough drain line daily per our commitments
- 2) Recommend cleaning the drain lines in bays 7 and 11.
