Dear Dr. Murley:
Subject:
Oyster Creek Nuclear Generating Station Docket No. 50-219 IE Bulletin 86-02, Response to Action No.1 IE Bulletin 86-02 " Static-0-Ring Differential Pressure Switches" was received at the Oyster Creek Nuclear Generating Station on July 22, 1986. Action Item No.1 required a report to be submitted on the identified switches within seven (7) days. This letter meets the requirements of Action Item No.1.
Attachment I documents the four applications of the identified SOR, Inc.
switches at the Oyster Creek Nuclear Generating Station. This information is correct as of the date of this letter.
However, it should be noted that the last two applications listed on the attachment (Reactor Low Level and Reactor Low-Low Level) are presently scheduled for replacement by an analog trip system during the present refueling outage.
If any further information is required, please contact Mr. John Rogers of my staff at (609)971-4893.
Very truly yours, w 1
