- Ken, In case I did not send the draft RAI previously:
By letter dated July 16, 2013, (Agencywide Documents Access and Management Systems Accession Number [ADAMS] ML13199A037), Exelon Generation Company, LLC. (the licensee),
submitted a license amendment request to revise the Quad Cities Nuclear Station, Units 1 and 2 Technical Specifications to support use of neutron absorbing inserts in spent fuel pool.
REQUEST FOR ADDITIONAL INFORMATION QUAD CITIES NUCLEAR POWER STATIONS, UNITS 1 AND 2 REGARDING USE OF NEUTRON ABSORBING INSERTS IN SPENT FUEL STORAGE RACKS DOCKET NOS.: 50-254 AND 50-265 TAC NOS.: MF2489 AND MF2490
- 1. On page 23 of the July 16, 2013 submittal, it states The surveillance trees were placed within one of the QCNPS SFPS Since SFP conditions in each Unit could be different, identify in which Units SFP are the trees placed and whether the placement is considered bounding for both pools. Discuss why placement of coupons in one pool will ensure adequate material surveillance representing all panels.
- 2. On page 26 of the July 16, 2013 submittal, it states Two rack inserts from the Unit 1 SFP will be visually inspected. Discuss and justify whether inserts from Unit 2 will be visually inspected. If the inserts in Unit 1 are the only ones to be visually inspected, please discuss why a Unit 2 inspection is not necessary.
- 3. In NET-300054-01 Rev 0, the visual inspection of the coupons revealed some rust colored pitting.
- a. For coupons F15 and F16, discuss the cause of this pitting. Include whether the pitting is indicative of what the SFP inserts may be experiencing.
- b. For coupon F11, discuss whether the carbon steel tool chain was the cause of the large pit. If not, discuss the cause of the large pit.
If you require a call for clarification, let me know as soon as possible. Otherwise I will discuss a final response by March 24, 2014.
