r-SYSTEMATIC EVALdATION' PROGRAM g
TOPIC lil-8.A MILLSTONE 1 TOPIC:
III-8. A, Loose Parts Monitoring and Core Barrel Vibration Program 1.
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 struc-
. tu re.
The objective is to detect loose. parts or excessive vibration be-fore 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.
.s 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 2, 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 capable of detecting acoustic dis-turbances, specifications for system sensitivity, alert levels, data acquisition modes and other system and procedural requirements.
Millstone 1 does.not have a loose parts monitoring program that meets the criteria of this guide.
2.
CORE BARREL VIBRATION:
This concern is only for plants built by Combustion Engineering and has been resolved generically.
r VI.
CONCLUSION 1.
A Loose Parts Monitoring Program, (i.e., detection system and proce-dures 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
'<t Millstone 1.
2.
This issue is deleted for Millstone 1.
The need to actually implement a loose Parts Monitoring Propam will be deter-mined during the integrated assessment.
