Nuclear Regulatory Commission August 16, 1999 Page 2 Corporation is notifying the NRC of its intention to perform
' future Low Power Physics Testing (LPPT) at Catawba and McGuire using the Westinghouse developed DRWM technique.
The supporting analytical computations for this technique will-be
. performed.by Duke..-Subject to NRC's concurrence, the first applications of' Duke's analytical computations to support DEWM in LPPT will' occur with the startups of McGuire Unit 1, Cycle 14 and Catawba Unit 2 Cycle 11. -These startups are projected to occur on or~about' October 31, 1999 and April 2000, respectively.
The application of this technique, described in WCAP-13360-P-A, Revision 1, was approved by the NRC as documented in References 1-and 2.
The Westinghouse application of DRWM at Catawba and McGuire, as well as the upcoming planned
-applications of DRWM by Duke, meet the NRC provisions for use as defined in Reference 2.
the attached Topical Report DPC-NE-2012, " Dynamic Rod Worth i
Measurement Using CASMO/ SIMULATE," dated August 1999 describes the results of the six DRWM benchmark cycles at Catawba and
-McGuire and discusses Duke's qualification to use DRWM at Catawba and McGuire.
Please address any comments or questions regarding this matter to J. S. Warren at (704) 382-4986 or P. M. Abraham at (704) 382-4520.
