Subject:

Monticello - Draft RAI on Relief Request (TAC ME8093)

Randy and Rick:

The NRC staff is reviewing the licensees September 28, 2011, letter which conveys a number of relief requests. The NRC staff has developed the following two questions regarding Relief Request PR-06:

(1) Section 5 states that: For determination of whether the In-service Testing (IST)

Acceptance Criteria is met, Table 1 and Table 2 are proposed to be used to analyze the data. Both Tables have a note that states For Information Only, actual data may change during 5th IST Interval. Please explain how the tables can be used to analyze the data, when the tables are for information only and the data may change.

(2) Table 2 has a column titled Lower Alert Range (<psid). The values in this column are 0.93 times the differential pressure reference value, which is the upper end of the alert range. Based on these values, should this column not be titled Upper Alert Range (<psid) instead?

You may choose to accept this e-mail as conveying a formal RAI. If you need clarification of the questions, the NRC staff would be glad to discuss these questions with you in a conference call. In order to meet your need date of September 1, 2012, we request that you formally respond no later than August 15, 2012.
