SUPPLEMENT TO REQUESTS FOR RELIEF
ENTERGY OPERATIONS, INC.RIVER BEND STATION - UNIT 1
RESPONSE TO NRC REQUEST FOR ADDITIONAL INFORMATION REGARDING RELIEFREQUESTS RBS-ISI-016 AND RBS-ISI-017
Question 1:
In the RAI we asked if Entergy had performed any other examinations in the area of the CRDHousing welds. Entergy responded in saying that in the 2 nd 10-year IS[ interval it performed VT-1 visual examinations of CRD bolting and found some with some of the bolting that had pittingand corrosion. Entergy stated it removed the bolts and replaced them. The question is didEntergy determined what was the root cause of the pitting and corrosion of the bolting?
Response:
The subject indications were documented on inspection reports and addressed under theCorrective Action Process. The level of classification of the conditions did not warrant theperformance of root cause or apparent cause evaluations. The conditions were characterizedby use of a supplemental examination method (eddy current), then evaluated against pre-established acceptance criteria and found acceptable. The conditions were corrected byreplacement of the subject fasteners under the Work Management Process.
Pages 3 - 15 are a sample of an unsatisfactory examination, a supplemental examination, theassociated evaluation and a page from the Work Order that replaced the subject fasteners.
Question 2:
The other issue is in one of the RAI questions we asked Entergy if it had considered using aremote camera to examine the CRD welds since there have been improvements in quality of theequipment, Entergy answered no. Will Entergy consider using a remote camera for the nextinterval; in this case for RBS it would be the 3 rd 10-year interval.
Response:
Entergy will continue to investigate and evaluate for suitability alternative inspection methods,such as the remote camera suggested by the NRC, for the third and subsequent ISI intervals aslong as the impracticality remains. It should be noted that Entergy fully understands that use ofany examination method other than the volumetric or surface method specified in ASME Code,Section XI, Table IWB-2500-1 will require relief approved by the NRC.
Since the ISI scope for the upcoming refueling outage (RF-17) has been selected,implementation of alternative methods determined to be suitable would begin Spring 2015, whichcorresponds with refueling outage RF-18.
