SUPPLEMENTARY INFORMATION: Supplement 1 of RIS 2002–22, ‘‘Clarification on Endorsement of Nuclear Energy Institute Guidance in Designing Digital Upgrades in Instrumentation and Control Systems’’ (ADAMS Accession No. ML18143B633), is intended for (1) all holders of operating licenses under part 50 of title 10 of the Code of Federal Regulations (CFR), ‘‘Domestic Licensing of Production and Utilization Facilities,’’ and (2) all holders of a combined license under 10 CFR part 52, ‘‘Licenses, Certifications, and Approvals for Nuclear Power Plants.’’ PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 In 2002, the NRC staff issued RIS 2002–22 to notify addressees that the NRC staff had reviewed NEI–01–01 and was endorsing the report for use as guidance in designing and implementing digital upgrades to nuclear power plant instrumentation and control systems. Following the NRC staff’s 2002 endorsement of NEI 01–01, holders of operating licenses have used this guidance in support of digital design modifications implemented without prior NRC approval in accordance with 10 CFR 50.59. The NRC inspections of documentation for these activities uncovered inconsistencies in the performance and documentation of engineering evaluations and associated technical bases for determinations on the 10 CFR 50.59(c)(2) evaluation criteria. This RIS Supplement clarifies the RIS 2002–22 endorsement of the NEI 01–01 guidance by providing additional guidance for developing and documenting ‘‘qualitative assessments’’ that are used to provide an adequate basis for a licensee’s determination that a digital modification will exhibit a low likelihood of failure to support a conclusion when applying the evaluation criteria set in 10 CFR 50.59, that a license amendment is not needed. The NRC published a notice of opportunity for public comment on a previous draft of this RIS in the Federal Register on July 3, 2017 (82 FR 30913). Subsequently, the NRC published a second notice of opportunity for public comment on the revised RIS on March 14, 2018 (83 FR 11154). As noted in the March 14, 2018 Federal Register notice (FRN), ‘‘[t]he NRC staff engaged in multiple communications with the public and stakeholders and continued internal discussions about the RIS. As a result of these efforts, the NRC has substantially rewritten the RIS. Due to the extensive nature of these revisions, and in light of this additional opportunity for comment, the NRC is not directly responding to each comment received in the previous comment period.’’ The NRC received comments from seven commenters as a result of the March 14, 2018 FRN. The NRC considered all comments, some of which resulted in changes to the RIS, and discussed the evaluation of these comments and the resulting changes to the RIS in a memorandum that is E:\FR\FM\25JNR1.SGM 25JNR1 29438 Federal Register / Vol. 83, No. 122 / Monday, June 25, 2018 / Rules and Regulations publicly available in ADAMS under Accession No. ML18115A298.

SUPPLEMENTARY INFORMATION: Supplement 1 of RIS 2002-22, ``Clarification 
on Endorsement of Nuclear Energy Institute Guidance in Designing 
Digital Upgrades in Instrumentation and Control Systems'' (ADAMS 
Accession No. ML18143B633), is intended for (1) all holders of 
operating licenses under part 50 of title 10 of the Code of Federal 
Regulations (CFR), ``Domestic Licensing of Production and Utilization 
Facilities,'' and (2) all holders of a combined license under 10 CFR 
part 52, ``Licenses, Certifications, and Approvals for Nuclear Power 
Plants.''
    In 2002, the NRC staff issued RIS 2002-22 to notify addressees that 
the NRC staff had reviewed NEI-01-01 and was endorsing the report for 
use as guidance in designing and implementing digital upgrades to 
nuclear power plant instrumentation and control systems. Following the 
NRC staff's 2002 endorsement of NEI 01-01, holders of operating 
licenses have used this guidance in support of digital design 
modifications implemented without prior NRC approval in accordance with 
10 CFR 50.59. The NRC inspections of documentation for these activities 
uncovered inconsistencies in the performance and documentation of 
engineering evaluations and associated technical bases for 
determinations on the 10 CFR 50.59(c)(2) evaluation criteria. This RIS 
Supplement clarifies the RIS 2002-22 endorsement of the NEI 01-01 
guidance by providing additional guidance for developing and 
documenting ``qualitative assessments'' that are used to provide an 
adequate basis for a licensee's determination that a digital 
modification will exhibit a low likelihood of failure to support a 
conclusion when applying the evaluation criteria set in 10 CFR 50.59, 
that a license amendment is not needed.
    The NRC published a notice of opportunity for public comment on a 
previous draft of this RIS in the Federal Register on July 3, 2017 (82 
FR 30913). Subsequently, the NRC published a second notice of 
opportunity for public comment on the revised RIS on March 14, 2018 (83 
FR 11154). As noted in the March 14, 2018 Federal Register notice 
(FRN), ``[t]he NRC staff engaged in multiple communications with the 
public and stakeholders and continued internal discussions about the 
RIS. As a result of these efforts, the NRC has substantially rewritten 
the RIS. Due to the extensive nature of these revisions, and in light 
of this additional opportunity for comment, the NRC is not directly 
responding to each comment received in the previous comment period.''
    The NRC received comments from seven commenters as a result of the 
March 14, 2018 FRN. The NRC considered all comments, some of which 
resulted in changes to the RIS, and discussed the evaluation of these 
comments and the resulting changes to the RIS in a memorandum that is

[[Page 29438]]

publicly available in ADAMS under Accession No. ML18115A298.
    As noted in 83 FR 20858 (May 8, 2018), this document is being 
published in the Rules section of the Federal Register to comply with 
publication requirements under 1 CFR chapter I.

    Dated at Rockville, Maryland, this 20th day of June 2018.

    For the Nuclear Regulatory Commission.
