ACCESSION #: 9707150337



                         Interim Report (97-005)



Subject;



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

(a)(2)



Title:



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.



Discovery Date:



May 13, 1997



Corrective Actions to Date:



Nonconformance report (NCR 6159) was prepared and processed by the

of a response to the NRC inspection report.



Evaluation Completion Schedule Date:



See "Corrective Actions to Date" above
