Dear Mr. Marion:

SUBJECT:

TRANSMITTAL OF DRAFT TECHNICAL REPORT DOCUMENTING THE PARAMETRIC EVALUATION OF SUMP SCREEN BLOCKAGE AT PRESSURIZED WATER REACTORS A public meeting between the NRC, the Nuclear Energy Institute, and the three Pressurized Water Reactor Owners Groups has been scheduled for July 26 and 27, 2001, to discuss the preliminary findings from the Generic Safety Issue (GSI) 191 study, Assessment of Debris Accumulation on PWR Sump Performance. The preliminary findings are documented in the draft Los Alamos National Laboratory report entitled, GSI-191: Parametric Evaluation for Pressurized Water Reactor Recirculation Sump Performance, dated July 2001. This report documents the parametric evaluation of sump screen blockage that was performed as part of the GSI-191 study. The draft report has been made publicly available to facilitate discussions with the industry at the July public meeting on the preliminary technical findings from the GSI-191 study.

If you have any questions regarding the enclosure to this letter, please contact Michael Marshall (301-415-5895). If you have any questions regarding arrangements for the July 26 and 27, 2001 public meeting, please contact Joe Birmingham (301-415-2829).

Sincerely,

/RA/
