Subject:

FW: TS Bases revisions Alan Regarding the I&C reviewer's question concerning our markup of the TS Bases in our application for 24-month fuel cycles, we will alter our planned revisions to delete the reference to "operating experience" as a basis for extension of a Surveillance Requirement from 18 to 24 months.

For example, the current wording typically reads, "Operating experience has shown these components usually pass the Surveillance when performed at the 18 month Frequency." This statement is found in numerous locations in the Bases.

We will revise such statements to read, typically, "Instrument drift analysis has concluded that the components can be reliably expected to pass the Surveillance when performed at the 24 month Frequency."

Please let me know if there are any further questions on this matter.
