However, in the Three Mile Island Nuclear Station Unit 1 (TMI-1) License Renewal Application (LRA), Amergen Energy Company, LLC, (the applicant) has indicated that degradation of Boral is insignificant and no AMP is required. The applicant provided several justifications for not having an AMP, but has stated that they will continue to implement a surveillance program. |
| | In order to complete its review, the staff requests that the applicant provide a description of the surveillance program that will be implemented during the period of extended and include the following information in the response: |
| | : 1. Provide the scope of the program, including the structures and components that will be under surveillance. |
| | : 2. Describe how the neutron-absorbing capacity and degradation of material will be monitored, including a description of the parameters, calculations, and acceptance criteria. |
| | : 3. Discuss how the structures and components will be maintained for the period of extended operation, including the methods, techniques (e.g., visual, weight, volumetric, surface inspection), frequency, sample size, data collection and timing. |
| | : 4. Confirm that TMI-1 has sufficient Boral coupon samples to maintain the sampling frequency through the period of extended operation. Also include: |
| | : a. The location of coupons relative to the spent fuel racks. |
| | : b. The mounting of the coupons and whether or not they are fully exposed to the spent fuel pool water. |
| | : c. The specific testing procedures used for determining Boral-10 areal density, verifying surface corrosion, (if any), and examining for blister formation. |
| | : d. The location of the coupons after removal from the pool for inspection and reinsertion in the pool. |
| | : 5. Describe how Boral will be monitored and trended. |
| | : 6. Describe the acceptance criteria of the program and how it ensures that Borals structure and function are maintained over the period of extended operation. |
| | : 7. Describe the corrective actions that would be implemented if coupon test results are not acceptable. |
| | : 8. In September 2003, inspection of Boral test coupons at Seabrook Nuclear Station revealed bulging and blistering of the aluminum cladding. Discuss the impact, if any, that this event is considered to have on the Boral surveillance program at TMI-1. |

SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION FOR BORAL NEUTRON ABSORBING MATERIAL IN SPENT FUEL POOL RACKS, THREE MILE ISLAND NUCLEAR STATION, UNIT 1, LICENSE RENEWAL APPLICATION (TAC NO. MD7701)
Dear Mr. Gallagher:
By letter dated January 8, 2008, AmerGen Energy Company, LLC (AmerGen) submitted an application pursuant to 10 Code of Federal Regulation (10 CFR Part 54) to renew the operating license for Three Mile Island Nuclear Station, Unit 1 for review by the U.S. Nuclear Regulatory Commission (NRC or the staff). The staff is continuing to review the information contained in the license renewal application and has identified, in the enclosure, areas where additional information is needed to complete the review. Further requests for additional information may be issued in the future.
Items in the enclosure were discussed with Chris Wilson, of your staff, and a mutually agreeable date for the response is within 30 days from the date of this letter. If you have any questions, please contact me at 301-415-2878 or e-mail Jay.Robinson@nrc.gov.
Sincerely,
\RA\

REQUEST FOR ADDITIONAL INFORMATION BORAL NEUTRON ABSORBING MATERIAL IN SPENT FUEL POOL RACKS THREE MILE ISLAND NUCLEAR STATION, UNIT 1 LICENSE RENEWAL APPLICATION DOCKET NUMBER 50-289 RAI#: 3.3.2.2.6-1 Reduction of Neutron-Absorbing Capacity and Loss of Material due to General Corrosion The Generic Aging Lessons Learned (GALL) Report recognizes the possibility of the existence of aging effects in the Boral used in the spent fuel storage racks and the need for having a plant specific aging management program (AMP). However, in the Three Mile Island Nuclear Station Unit 1 (TMI-1) License Renewal Application (LRA), Amergen Energy Company, LLC, (the applicant) has indicated that degradation of Boral is insignificant and no AMP is required. The applicant provided several justifications for not having an AMP, but has stated that they will continue to implement a surveillance program.
In order to complete its review, the staff requests that the applicant provide a description of the surveillance program that will be implemented during the period of extended and include the following information in the response:
- 1. Provide the scope of the program, including the structures and components that will be under surveillance.
- 2. Describe how the neutron-absorbing capacity and degradation of material will be monitored, including a description of the parameters, calculations, and acceptance criteria.
- 3. Discuss how the structures and components will be maintained for the period of extended operation, including the methods, techniques (e.g., visual, weight, volumetric, surface inspection), frequency, sample size, data collection and timing.
- 4. Confirm that TMI-1 has sufficient Boral coupon samples to maintain the sampling frequency through the period of extended operation. Also include:
- a. The location of coupons relative to the spent fuel racks.
- b. The mounting of the coupons and whether or not they are fully exposed to the spent fuel pool water.
- c. The specific testing procedures used for determining Boral-10 areal density, verifying surface corrosion, (if any), and examining for blister formation.
- d. The location of the coupons after removal from the pool for inspection and reinsertion in the pool.
- 5. Describe how Boral will be monitored and trended.
- 6. Describe the acceptance criteria of the program and how it ensures that Borals structure and function are maintained over the period of extended operation.
- 7. Describe the corrective actions that would be implemented if coupon test results are not acceptable.
- 8. In September 2003, inspection of Boral test coupons at Seabrook Nuclear Station revealed bulging and blistering of the aluminum cladding. Discuss the impact, if any, that this event is considered to have on the Boral surveillance program at TMI-1.
Industry experience has indicated that during longer exposure such blisters may form.
Since formation of blisters may affect the efficiency of the Boral panels to attenuate neutrons (through flux trap formation) and may cause deformation of the fuel cells, explain why blistering will not be a safety concern.
- 9. Discuss any other operating experience of Boral that may be applicable to TMI-1 and describe why it will not be a safety concern.
- 10. Describe how the Water Chemistry program will be used to manage the loss of material due to general corrosion of Boral. Include the parameters that will be monitored, the parameters acceptance criteria, and how they will effectively manage the loss of Boral.
