e SYSTEMATIC EVALUATION PROGRAM TOPIC III-8.A BIG ROCK POINT TOPIC:. III-8.A, Loose Parts Monitoring and Core Barrel Vibration Program I.
INTRODUCTION The purpose of this topic is t9 review the inserv*ice surveillance program to detect loose parts and excessive motion of the main core support struc-
. ture.
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.
III.
RELATED SAFETY TOPICS AND INTERFACES V-i, Compliance With Codes and Standards (10 CFR 50.55a)o IV.
REVIEW GUIDELINES See Evaluation.

EVALUATION
- 1.
LOOSE PARTS MONITORING:
R.G. 1.133, "Loose-Part Detection Program for the Primary System.of Light-Water-Cooled Reactors, 11 Revision 2, describes features for monitoring loose parts w.ithin the reactor coolant pres*sure bounda-ry
"(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.
Big Rock Point does not have a loose parts monitoring.Program that meets th~ criteria of this guide.
- 2.
CORE BARREL VIBRATION:
This concern is only for plants built by Combustion Engineering and has been resolved generically.

VI.
CONCLUSION i;. A Loose Parts Monitoring Program, (i.e., detection system and proce-dures as spec1fied in-Section C.2 and C.3 of R.G. 1.133, Rev~.1) as currently required for new facilities does not exist at* Big Rock Point.*
- 2.
The portion of Topic III-8.A related to Core Barrel Vibr.ations does* not apply to Big Rock Point.
Th.e need to actually implement a Loose Parts Monitoring Program will.be deter-mined during the integrated assessment.
