Monticello - Draft RAI from EICB re. Proposed EPU Amendment (TAC MD9990)

Ken:

Our review of your 11/5/09 application for an extended power uprate amendment is ongoing.

Our Instrumentation and Controls Branch (EICB) has provided the following draft RAI questions. Please contact me to set up a conference call to discuss these questions:

(1) Enclosure 5, Page 2-104, Table 2.4-1, identifies various instrument setpoints where analytical and/or allowable values have been changed. Provide a summary calculation for the revised setpoints. This summary calculation should provide all the values calculated in accordance with the setpoint methodology, such as acceptable as found band, acceptable as left value, etc., and a reasoned quantitative or qualitative analysis for these values.

(2) The surveillance frequency in TS Section 3.3.1.1, Surveillance Requirement SR 3.3.1.1.6, is proposed to be revised from 2000 effective full power hours to 1770 full power hours, However, no detailed analysis to justify the change was provided. Please provide the calculation to demonstrate the basis for the proposed change.

This e-mail aims solely to prepare you and others for the requested conference call. This e-mail does not convey a formal NRC staff position, and does not formally request for additional information.
