1. Section 9.2 of Attachment 2 to the licensing amendment application dated July 5, 2002, addresses Design Basis Accidents (DBA). The submittal states that radiological consequences due to postulated DBAs have been calculated using a source term of 102% of the current licensed reactor thermal power. However, the staff finds that the analyses addressed in the Updated Final Safety Analysis Report (UFSAR) appears to indicate that the radiological consequences may have been determined at the current rated thermal power. Please provide discussion on the analyses/evaluation addressed in Section 9.2, identifying changes, if any, to the assumptions, methodologies, and accidents analyzed from those documented in the UFSAR. Please provide the results and acceptance criteria of the analyses referenced in Section 9.2.

2. Provide details about the grid stability analysis including assumptions and results and conclusions for the power uprate condition. Also, provide in detail (including the ratings) the effect of the power uprate on the following equipment:

a. Main generator

b. Isophase bus

c. Main power transformer

d. Startup transformer

e. Auxiliary transformer

f. Non-Class 1E loads increased Enclosure
