Dear Mr. Liu:
SUBJECT:
DUANE ARNOLD ENERGY CENTER (DAEC) PROPANE TANK l
As part of the resolution for Generic Safety Issue (GSI) 106, the staff-has raised a concern associated with the 500 gallon propane tank located about 25 feet from the turbine building at DAEC. The concern relates to the potential i
impact that this tank may have on the Emergency Diesel Generators (EDG) during i
a seismic event.
If a seismic event were to occur, a loss of offsite power -
could occur as a result of the failure of the ceramic insulators on the station transformer. This demand would start the EDGs.
The seismic event i
could also cause a failure of the subject propane tank.
The tank failure could result in a loss of the EDGs and result in a station blackout. 'It is postulated that the faiiure and damage to the EDGs would' be related to ingestion of propane-through the combustion air-intakes.
Enclosed is a copy of a memorandum dated February 11, 1993, which identified the concerns associated with the tank.
Your staff had verbally informed NRR that you plan to include the propane tank l
in your Individual Plant' Examination of External Events (IPEEE),
You should i~
be assured that DAEC is meeting its' licensing basis for EDG operability requirements. However, please confirm in writing that you will accomplish the above in your IPEEE program.
Sincerely,.
