NUCLEAR REGULATORY COMMISSION

10 CFR Part 50

[Docket No. PRM-50-109; NRC-2014-0257]


Improved Identification Techniques Against Alkali-Silica Reaction 
Concrete Degradation at Nuclear Power Plants

AGENCY: Nuclear Regulatory Commission.

ACTION: Petition for rulemaking; notice of docketing, and request for 
comment.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) has received a 
petition for rulemaking (PRM) from Sandra Gavutis on behalf of C-10 
Research and Education Foundation (C-10 or the petitioner), dated 
September 25, 2014, requesting that the NRC amend its regulations to 
provide improved identification techniques against Alkali-Silica 
Reaction (ASR) concrete degradation at nuclear power plants. The 
petition was docketed by the NRC on October 8, 2014, and has been 
assigned Docket No. PRM-50-109. The NRC is requesting public comments 
on this petition for rulemaking.

II. The Petitioner

    The petition states that C-10 is a non-profit organization that 
``evolved from'' Citizens within the Ten-Mile Radius, which C-10 claims 
is a 5,000 member organization founded in 1986 to challenge evacuation 
plans for the [NextEra] Seabrook Station reactor. The petition 
represents that C-10 was established in 1991 to address the health and 
safety issues related to the [NextEra] Seabrook Station nuclear power 
plant. The petition further states that ``C-10 has been engaging the 
NRC about concrete degradation at Seabrook since December 22, 2011,'' 
and that the Union of Concerned Scientists assisted C-10 in preparing 
this petition.

III. The Petition

    Sandra Gavutis, Executive Director, submitted a PRM on behalf of C-
10, dated September 25, 2014 (ADAMS Accession No. ML14281A124), 
requesting that the NRC amend its

[[Page 1477]]

regulations to improve identification techniques against ASR concrete 
degradation at nuclear power plants. The NRC has determined that the 
petition meets the threshold sufficiency requirements for a PRM under 
Sec.  2.802 of Title 10 of the Code of Federal Regulations, ``Petition 
for rulemaking,'' and the petition has been docketed as PRM-50-109. The 
NRC is requesting public comments on this PRM.

IV. Discussion of the Petition

    At an NRC public meeting at Seabrook Station on June 24, 2014, the 
petitioner asked the NRC if the agency was investigating the U.S. 
nuclear fleet for ASR concrete degradation. The NRC staff responded 
that ASR concrete degradation could be adequately indicated through 
visual examination. However, an NRC position paper, ``In Situ 
Monitoring of ASR-affected Concrete,'' November 2012 (ADAMS Accession 
No. ML13108A047), states, ``ASR can exist in concrete without 
indications of pattern cracking,'' and that for ``. . . structures 
exposed to ASR, internal damage occurs through the depth of the section 
but visible cracking is suppressed by heavy reinforcement. . . .'' When 
NextEra determined 131 locations with ``assumed'' ASR visual signs 
within multiple power-block structures at Seabrook Station during 2012, 
further engineering evaluations were not required by the NRC.
    The petitioner requests that the NRC amend its regulations to 
improve identification techniques against ASR concrete degradation at 
U.S. nuclear power plants. The petitioner suggests that the reliance on 
a visual inspection does not ``adequately identify Alkali-Silica 
Reaction (ASR), does not confirm ASR, or provide the current state of 
ASR damage (if present) without petrographic analysis under current 
existing code.'' The petitioner asserts that codes and standards exist 
that are capable of detecting ASR and determining the key material 
properties needed to evaluate the degree and severity of ASR damage. 
American Concrete Institute (ACI) Standard 349.3R, ``Evaluation of 
Existing Nuclear Safety-Related Concrete Structures,'' for instance, 
has been endorsed by the NRC (ADAMS Accession No. ML112241029) as an 
acceptable method of protecting against excessive ASR concrete 
degradation, but is not a regulatory requirement. The petitioner 
requests that the NRC amend its regulations to require that all 
licensees comply with industry codes and standards that have ``already 
been endorsed by the agency,'' and identified two standards for which 
the NRC's regulations should require compliance: (1) ACI Standard 
349.3R; and (2) American Society for Testing & Materials (ASTM) C856-
11, ``Standard Practice for Petrographic Examination of Hardened 
Concrete.''

    Dated at Rockville, Maryland, this 5th day of January, 2015.

    For the Nuclear Regulatory Commission.
Annette L. Vietti-Cook,
Secretary of the Commission.
