SUBJECT:

ANNOUNCEMENT OF SAFETY SYSTEM OPERATIONAL PERFORMANCE INSPECTION

Dear Mr. Wadley:

This is to inform you that the NRC will perform a safety system operational performance l inspection (SSOPI) at the Prairie Island Nuclear Generating Plant. We have chosen the i auxiliary feedwater, the safeguards chilled water, and the control room eentilation systems l 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 era scheduled for the weeks of April 28 and May 12,1997. The details of this inspection, -.wding the systems, were communicated to your staff (Mr. Albrecht of your engineering de rtment) on Friday, March 14,1997.

The details of the inspection were confirmed in a (,Jnversation between the senior resident inspector and Mr. Albrecht on Monday, March 17,1997.

The inspection will assess operation, design, maintenance, surveillance, quality assurance, and corrective actions associated with the selected Prairie Island systems, with a 1 concentration on the operations and design aspects. To accomplish its objectives, the SSOPl team will review a broad range of information and system activities.

)

1 In order to most effectively perform this task, we would appreciate your providing information on the selected systems, as shown on the attached list. We would apfreciate your having this information available for the team the afternoon of April 14,1997.

Members of the team will be at the plant the week of April 14 to prepare for the j inspection, gain some familiarity with your facility and fulfill access requirements. l l

We would also appreciate it if you would arrange for short system overview. presentations I during this week and a general plant tour, including as much of the selected system as is j reasonably accessible.
