SYSTEMATIC EVALUATION PROGRAM TOPIC III-8.A LACROSSE TOPIC:

III-8. A. LOOSE PARTS MONITORING AND CORE BARREL VIBRATION PROGRAM I.

INTRODUCTION

~ The purpose of this topic is to review the inservice surveillance program to detect loose parts and excessive motion of the main core support structure. The objective is to detect loose parts or excessive vibration before they can cause flow blockage or mechanical damage to the fuel or other safety related components.

II.

REVIEW CRITERIA Standard Review Plan (SRP) Section 4.4, Regulatory Guide (R.G.)

1.133.

III.

RELATED SAFETY TOPICS AND INTERFACES V-1 Compliance with codes and standards (10 CFR 50.55a).

IV.

REVIEW GUIDELINES See Evaluation.

V.

Evaluation 1.

LOOSE PARTS MONITORING:

' R.G.1.133, " Loose-Part Detection Program for the Primary System of Light-Water-Cooled Reactors," Revision 1, describes features for monitoring loose parts within the reactor coolant pressure boundary (RCPB). These features include sensors strategically located on the exterior surface of the,RCPB caoable of detecting acoustic disturbances, specifications for system sensitivity, alert levels, data acquistion modes and other system and procedural requirements. Lacrosse does not have a loo'se parts monitoring program that meets the criteria of this guide.

2.

CORE BARREL VIBRATION:

This issue is only a problem for Combustion Engineering built plants.

r

' ' VI. C0fiCLUSION 1.

A Loose Parts Mortitoring Program, (i.e., detection system and-procedures as specified in Section C.2 and C.3 of R.G. 1.133, Rev. 1) as currently required for.new facilities does not exist at the Lacrosse facility. The need to actually implement a Loose Parts Monitoring Program will be determined during the integrated assessment.

2.

The core barrel vibration issue has been deleted for Lacrosse.
