Subject:

LaSalle County Flation Unit 2 Fine Motion Contcol Rod Drive Demonstration Test License NPF-18 NRC Docket No. 50-374

Dear Mr. Denton:

Attached for your review and approval is a General Electric Topical Report entitled LaSalle Unit 2 Fine Motion Control Rod Drive Demonstration Test Description NEDO 31130, dated December, 1985. The proposed test consists of replacing one peripheral locking piston control rod drive module with a Fine Motion Control Rod Drive for approximately one plant fuel cycle.

At the end of the test period, the FMCRD will be removed for inspection and the plant restored to its pretest configuration.

This Topical Report will serve as the basis for a planned Technical Specification change request to follow shortly. The installation of the FMCRD is planned during the upcoming Unit 2 Fall 1986 refueling outage. The proposed test for Unit 2 is the same as the one originally scheduled for Unit 1 in the ongoing outage. The Topical Report NEDO 31130 has included more detailed discussion of the plant modification and the effect on installed systems. Also included is a more detailed discussion of appli-cable code considerations.

Please direct any questions you may have concerning this matter to this office. A fee remittance of $150.00 is enclosed in accordance with 10 CFR 170.
