SUPPLEMENTARY INFORMATION: On February 8, 2017, the petitioner requested that the NRC take action with regard to Braidwood Station, Units 1 and 2, and Byron Station, Unit Nos. 1 and 2 (ADAMS Accession No. ML17061A127). The petitioner requested: (1) Issue a violation under part 50 of title 10 of the Code of Federal Regulations (10 CFR), appendix B, Criterion III, Design Control for deficiencies in the analysis of record (AOR) for the main steam isolation valve (MSIV) room pressurization following a high energy line break (HELB), (2) Issue a violation under 10 CFR part 50, appendix B, Criterion XVI, Corrective Action, for failure to update the AOR in a timely manner, (3) Require Exelon (the licensee) to show that the consequences of the secondary missiles resulting from MSIV room pressurization do not have adverse consequences, (4) Issue a demand for information under 10 CFR 2.204, ‘‘Demand for information,’’ to compare and contrast the behavior of Exelon management described in the petition with the NRC’s policy statement on the attributes of a safety-conscious work environment, and (5) Use Exelon’s response to number 4, above, on which to determine whether to issue a ‘‘chilling effects’’ letter. As the basis for this request, the petitioner states that: (1) Break enthalpies used in the MSIV room pressurization AOR are actually the thermodynamic internal energy of the steam, not the enthalpy. Since in the range of interest, the internal energy is about 13 percent less than the enthalpy, the energy flow to the areas of concern is non-conservative. Steam flow from secondary piping is neglected; (2) Corrective actions to resolve an issue in the AOR are long overdue (8 years) and improperly tracked; (3) A proposed revision to the AOR shows that the MSIV room roof slabs will be ejected by the high pressures in the MSIV rooms becoming potential missiles; and (4) Management dismissed information in the Updated Final Safety Evaluation Report (UFSAR) that supported the concerns about the AOR as ‘‘excessive detail’’ and directed personnel to remove the information. Management dismissed UFSAR internal inconsistency related to the ‘‘Break Exclusion Zone’’ without discussion or review and stated that the information supporting the concern could be deleted as an UFSAR cleanup item. Recently, there was an operability concern where engineering management maintained a E:\FR\FM\27JYN1.SGM 27JYN1 34994 Federal Register / Vol. 82, No. 143 / Thursday, July 27, 2017 / Notices position of operability in the face of conflicting information. The information that engineering management relied on to support operability was demonstrably irrelevant. The request, except for the petitioner’s item 3, which does not request enforcement action, is being treated pursuant to 10 CFR 2.206 of the Commission’s regulations. The request has been referred to the Director of the Office of Nuclear Reactor Regulation. As provided by 10 CFR 2.206, appropriate action will be taken on this petition within a reasonable time. The petitioner met with the Petition Review Board (PRB) on April 13, 2017, to discuss the petition; the transcript of that meeting is an additional supplement to the petition (ADAMS Accession No. ML17111A774). On June 12, 2017, the petition manager informed the petitioner that the PRB accepted the petition items 1, 2, 4, and 5 for review under 10 CFR 2.206.

SUPPLEMENTARY INFORMATION: On February 8, 2017, the petitioner 
requested that the NRC take action with regard to Braidwood Station, 
Units 1 and 2, and Byron Station, Unit Nos. 1 and 2 (ADAMS Accession 
No. ML17061A127). The petitioner requested: (1) Issue a violation under 
part 50 of title 10 of the Code of Federal Regulations (10 CFR), 
appendix B, Criterion III, Design Control for deficiencies in the 
analysis of record (AOR) for the main steam isolation valve (MSIV) room 
pressurization following a high energy line break (HELB), (2) Issue a 
violation under 10 CFR part 50, appendix B, Criterion XVI, Corrective 
Action, for failure to update the AOR in a timely manner, (3) Require 
Exelon (the licensee) to show that the consequences of the secondary 
missiles resulting from MSIV room pressurization do not have adverse 
consequences, (4) Issue a demand for information under 10 CFR 2.204, 
``Demand for information,'' to compare and contrast the behavior of 
Exelon management described in the petition with the NRC's policy 
statement on the attributes of a safety-conscious work environment, and 
(5) Use Exelon's response to number 4, above, on which to determine 
whether to issue a ``chilling effects'' letter.
    As the basis for this request, the petitioner states that: (1) 
Break enthalpies used in the MSIV room pressurization AOR are actually 
the thermodynamic internal energy of the steam, not the enthalpy. Since 
in the range of interest, the internal energy is about 13 percent less 
than the enthalpy, the energy flow to the areas of concern is non-
conservative. Steam flow from secondary piping is neglected; (2) 
Corrective actions to resolve an issue in the AOR are long overdue (8 
years) and improperly tracked; (3) A proposed revision to the AOR shows 
that the MSIV room roof slabs will be ejected by the high pressures in 
the MSIV rooms becoming potential missiles; and (4) Management 
dismissed information in the Updated Final Safety Evaluation Report 
(UFSAR) that supported the concerns about the AOR as ``excessive 
detail'' and directed personnel to remove the information. Management 
dismissed UFSAR internal inconsistency related to the ``Break Exclusion 
Zone'' without discussion or review and stated that the information 
supporting the concern could be deleted as an UFSAR cleanup item. 
Recently, there was an operability concern where engineering management 
maintained a

[[Page 34994]]

position of operability in the face of conflicting information. The 
information that engineering management relied on to support 
operability was demonstrably irrelevant.
    The request, except for the petitioner's item 3, which does not 
request enforcement action, is being treated pursuant to 10 CFR 2.206 
of the Commission's regulations. The request has been referred to the 
Director of the Office of Nuclear Reactor Regulation. As provided by 10 
CFR 2.206, appropriate action will be taken on this petition within a 
reasonable time. The petitioner met with the Petition Review Board 
(PRB) on April 13, 2017, to discuss the petition; the transcript of 
that meeting is an additional supplement to the petition (ADAMS 
Accession No. ML17111A774). On June 12, 2017, the petition manager 
informed the petitioner that the PRB accepted the petition items 1, 2, 
4, and 5 for review under 10 CFR 2.206.

    Dated at Rockville, Maryland, this 20th day of July, 2017.

    For the Nuclear Regulatory Commission.
Brian E. Holian,
Acting Director, Office of Nuclear Reactor Regulation.
