SUBJECT:
Darrell G. Eisenhut, Director Division of Licensing Office of Nuclear Reactor Regulation BOARD NOTIFICATION 82-125 (TMI-1 and DIABLO CANYON )
RECENT ACRS EVALUATION CONCERNING PNR FLOW BLOCKAGE In accordance with the present NRC procedures for board notification, the enclosed information is being transmitted directly to the Commission.
The notification relates to an evaluation concerning flow blockage during natural circulation which was performed by H. Etherington.
Our assessment has concluded we are in general agreement with all of the points identified in Mr. Etherington's evaluation, and that all of his concerns regarding the phenomena of natural circulation flow blockage ha",e been previously identified by the staff and provided to the bo'irds in Board Notification BN-82-71.
- However, due to the interest in natural circulation and feed and bleed cooling in recent licensing proceedings, we believe it is in the best interest of the regulatory process to make the licensing boards aware of this recent evaluation.
tie do not believe that these results adversely impact our present staff position regarding reliance on natural circulation or the validity of,'fhed and bleed cooling as a defense in depth measure.
The staff is continuing to pursue with the BSW Owners the requirement for them to provide acceptable integral system experimental test data to aid in code verification and emergency operator procedure evaluation as part of TMI-2 action items II.K.3.20 and I.C.l respectively.
l<e will inform the boards of significant information if it causes us to change our technical position.
