Subject:
Interim Report - DER 84-46 A 50.55(e) Potentially Reportable Deficiency Relating to Refueling Water Tank Penetration Sleeves.
File: 84-019-026; D.4.33.2
Reference:
Telephone Conversation between D. Hollenbach and T. Bradish on July 17, 1984
Dear Sir:
The NRC was notified of a potentially reportable deficiency in the referenced telephone conversation. At that time, it was estimated that a determination of reportability would be made within thirty (30) days.
Due to the extensive investigation and evaluation required, an Interim Report is attached. It is now expected that this information will be finalized by September 7,1984, at which time a complete report will be submitted.

'I.
Potential Problem Following completion of the final stress calculation for the Chemical and Volume Control' system (CH), it was determined that no design calculation had been performed for the sleeve-to pipe cap plate connection for two 20-inch diameter' pipes penetrating the Refueling Water Tank. Calculations were performed and revealed that the connection would be overstressed during a seismic event due to loads resulting from seismic anchor movement.
II.
Approach To and Status'Of Proposed Resolution Bechtel Engineering is currently studying this problem to determine reportability and technical justification for corrective action.
III.
Projected Completion of Corrective Action and Submittal of the Final Report Evaluation of this condition and submittal of the Final Report is forecast to be completed by September 7, 1984.
