On page 2 of Section 5, "Proposed Alternative and Basis for Use," of Enclosure D of the letter dated February 27, 2013, notes that comprehensive testing of the high pressure injection pumps will be performed each refueling outage instead of biennially for the fourth 10-year interval. It is stated in Section 7 that a similar relief request was authorized by the NRC for the third 1 0-year inservice testing interval at Davis-Besse Nuclear Power Station, Unit 1. Provide actual time frequency (months) of each refueling outage at which the comprehensive testing of the high pressure injection pumps was performed during the third 1 0-year inservice testing interval.
