SUBJECT:

ANNOUNCEMENT OF SAFETY SYSTEM OPERATIONAL PERFORMANCE INSPECTION (SSOPI) ON THE RESIDUAL HEAT REMOVAL SYSTEM

Dear Mr. Liu:

This is to inform you that the NRC will perform a safety system operational performance inspection (SSOPI) at the Duane Arnold Energy Center (DAEC). We have chosen the residual heat removal (RHR) system as the focus for this SSOPI, which will use NRC Inspection Procedure 93801 " Safety System Functional Inspection" emphasizing the system operation aspects of the procedure. The inspection's onsite activities are scheduled for the weeks of April 7 and 21,1997. The details of this inspection, including the systems, were communicated to your staff (Mr. Robert J. Murrell of your licensing department) on Wednesday, March 5,1997.

Tha inspection will assess operation, design, maintenance, surveillance, quality assurance, and corrective actions associated with the DAEC RHR system, with a concentration on the operations and design aspects. To accomplish its objectives, the SSOPl team wil! review a broad range of information and system activities.

In order to most effectively perform this task, we would appreciate your providing information on the RHR system, as shown on the enclosed list. We would appreciate your having this information available for the team the afternoon of March 24,1997. Members of the team will be at the plant the week of March 24, to prepare for the inspection, gain some familiarity with your facility and fulfill access requirements.

We would also appreciate it if you would arrange for a short system overview presentation during this week end a general plant tour, including as much of the RHR system as is reasonably accessW.
