                         Interim Report (97-005)


Interim report of evaluation of a deviation pursuant to 10 CFR 21.21



Adequacy of Systematically Meeting Generic Design Criteria for ATRIUM-10

Fuel Design

Identification of Basic Activity

Same as title

Basic Activity Supplied By:

Siemens Power Corporation - Nuclear Division

Nature of Deviation;

The NRC did not consider during NRC Inspection 99900081/97-01 SPC to have

sufficiently satisfied generic design criteria.  Further, issues

surrounding the ANFB CHF correlation as applied to ATRIUM-10 provided

support to this concern.  Specific to this example, the NRC believed that

SPC failed to implement all aspects of the methodology including handling

of the flow bias nature of the ATRIUM-10 CHF behavior.
