| | Seabrook License Amendment Request on Concrete Degradation |
| | |
| | ==Dear Chairman Bley:== |
| | |
| | On behalf of the C-10 Research and Education Foundation (C-10) 1 and the Union of Concerned Scientists (UCS),2 I am respectfully requesting that the Advisory Committee on Reactor Safeguards (ACRS) formally review and comment on a license amendment request regarding managing the risk of concrete degradation due to alkali-silica reaction (ASR). |
| | By letter dated August 1, 2016,3 NextEra Energy Seabrook LLC (NextEra) submitted a license amendment request seeking Nuclear Regulatory Commission (NRC) approval of proposed revisions to the current licensing basis at Seabrook for ASR. |
| | Because concrete degradation due to ASR is not explicitly covered by existing codes and standards, such as American Concrete Institute standards, the license amendment request seeks to manage ASR using a mix of existing codes and standards supplemented by site-specific monitoring and maintenance measures. |
| | A formal review of this license amendment request by the ACRS can add tangible value to the process. |
| | This is not to suggest inadequate performance on the part of the licensee staff or by the NRC staff reviewing the request. The material submitted by NextEra in the license amendment request and the request for additional information submitted by the NRC staff clearly demonstrate that both parties have applied considerable resources and skills to this matter. The value to be added by the ACRS is either in confirming that the proposed measures will very likely achieve the intended outcomes or in pointing out where those measures can be enhanced. |
| | Ensuring that ASR is properly managed at Seabrook has the collateral benefit of establishing a solid precedent should other NRC-licensed facilities encounter this degradation mechanism. |

SUBJECT:
Seabrook License Amendment Request on Concrete Degradation
Dear Chairman Bley:
On behalf of the C-10 Research and Education Foundation (C-10) 1 and the Union of Concerned Scientists (UCS),2 I am respectfully requesting that the Advisory Committee on Reactor Safeguards (ACRS) formally review and comment on a license amendment request regarding managing the risk of concrete degradation due to alkali-silica reaction (ASR).
By letter dated August 1, 2016,3 NextEra Energy Seabrook LLC (NextEra) submitted a license amendment request seeking Nuclear Regulatory Commission (NRC) approval of proposed revisions to the current licensing basis at Seabrook for ASR.
Because concrete degradation due to ASR is not explicitly covered by existing codes and standards, such as American Concrete Institute standards, the license amendment request seeks to manage ASR using a mix of existing codes and standards supplemented by site-specific monitoring and maintenance measures.
A formal review of this license amendment request by the ACRS can add tangible value to the process.
This is not to suggest inadequate performance on the part of the licensee staff or by the NRC staff reviewing the request. The material submitted by NextEra in the license amendment request and the request for additional information submitted by the NRC staff clearly demonstrate that both parties have applied considerable resources and skills to this matter. The value to be added by the ACRS is either in confirming that the proposed measures will very likely achieve the intended outcomes or in pointing out where those measures can be enhanced.
Ensuring that ASR is properly managed at Seabrook has the collateral benefit of establishing a solid precedent should other NRC-licensed facilities encounter this degradation mechanism.

For full disclosure, both C-10 and UCS have submitted comments on the license amendment request in response to the notice published in the Federal Register. But neither C-10 or UCS has formally intervened with the NRC contesting the amendment being sought. We have not enclosed our comments with this letter to avoid biasing the ACRSs review; but we would be glad to provide them upon request.
