REQUEST FOR ADDITIONAL INFORMATION SPRING 2014 STEAM GENERATOR INSPECTIONS ENTERGY OPERATIONS, INC.
ARKANSAS NUCLEAR ONE, UNIT 2 DOCKET NO. 50-368 By letter dated August 18, 2014 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML14230A898), Entergy Operations, Inc. (Entergy, the licensee) submitted information summarizing the results of the Spring 2014 steam generator tube inspections performed at Arkansas Nuclear One, Unit 2. These inspections were performed during refueling outage 23 (RFO 23). In a letter dated June 23, 2014 (ADAMS Accession No. ML14170A060), the U.S. Nuclear Regulatory Commission (NRC) staff summarized a conference call that was held with the licensee during RFO 23.
In order to complete the review, the NRC staff requests responses to the follow questions:
ESGB-RAI-1 The Cycle Effective Full Power Year (EFPY) and Cumulative SG EFPY columns in Table 1-1 agree with each other up until outage 2R20. Please confirm the values for EFPY in these columns.
ESGB-RAI-2 The NRC staff notes that in Tables 3.6.1 and 3.6.2 of the letter dated August 18, 2014, the %
Plugged columns appear to be incorrect based on the number of tubes plugged in each SG.
Please clarify.
ESGB-RAI-3 In the teleconference summary dated June 23, 2014, the NRC staff noted that an evaluation of blockage of the top support plate will be done as part of the eddy current auto-analysis that is verifying the position of the AVBs [anti-vibration bars]. Please discuss the results of the position verification of the AVBs and the evaluation of the blockage of the top support plate.
ESGB-RAI-4 Please discuss the results of the primary side channel head inspections and the tube plug inspections.
ESGB-RAI-5 Please provide a tubesheet map so the NRC staff can better understand the locations of the indications. In addition, please provide the thickness of the tubesheet with and without cladding.
ESGB-RAI-6 In Section 3.2 of the letter dated August 18, 2014, a number of dents were reported. It was indicated that these dents were present in the preservice inspection. Please discuss whether these dents have been increasing in size (voltage). Please discuss whether these dents are service-induced or have been present since the preservice inspection. If service-induced, please discuss the cause.
ESGB-RAI-7 A number of possible loose part (PLP) indications were reported in both steam generators. In steam generator B, three parts were removed, reducing the number of PLP indications to one.
Please discuss whether visual inspections were performed at all PLP locations. If visual inspections were performed, please discuss the results of these inspections. If any loose parts were left in the steam generators, please discuss the results of any assessments performed on the effect these parts may have on tube integrity.
