Prairie Island Nuclear Generating Plant Revision No. I to License Amendment Reauest - Dated June 24, 1983 Corrections to XN-NF-83-38 i

Prairie Island Units 1 and 2 Limiting Break LOCA-ECCS Analysis Using EXEM/PWR Correction 1 Page 5, 6th line from top The sentence "The unbroken loops were assumed symmetrical and modeled as one intact -loop with appropriately scaled input" should be eliminated. The sentence is inappropriate since the Prairie Island reactors have only two loops.

Correction 2 Page 5, 7th line from botton The sentence "This axial power profile in configuration with the current K(Z) function developed by the NSSS vendor will not be used to define operating envelope for F "q should be replaced with:

"The Fg determined with this axial profile in combination uith the current K(Z) function developed by the NSSS ven: dor will be used to define .

the envelope for F gwhere the K(Z) curve should be modified such that LHGRs are determined by the NSSS vendor analyses."

Correction 3 Page 8, Table 2.1 The table entry for primary coolant volume should be reduced from 10,309 to 10,247 ft to reflect the reduction in primary volume resulting from the plugging of 5% of the steam generator tubes.
