NUCLEAR REGULATORY 

COMMISSION 

10 CFR Chapter 1 

[NRC–2017–0154] 

Clarification on Endorsement of 

Nuclear Energy Institute Guidance in 

Designing Digital Upgrades in 

Instrumentation and Control Systems 

AGENCY: Nuclear Regulatory 

Commission. 

ACTION: Regulatory issue summary; 

issuance. 

SUMMARY: The U.S. Nuclear Regulatory 

Commission (NRC) issued a Regulatory 

Issue Summary (RIS) entitled, RIS 2002– 

22, Supplement 1, ‘‘Clarification on 

Endorsement of Nuclear Energy Institute 

Guidance in Designing Digital Upgrades 

in Instrumentation and Control 

Systems.’’ This RIS supplement clarifies 

RIS 2002–22, which remains in effect. 

The NRC continues to endorse Nuclear 

Energy Institute (NEI)–01–01, as stated 

in RIS 2002–22 and clarified RIS 2002– 

22, Supplement 1. This RIS supplement 

clarifies the guidance in RIS 2002–22 for 

preparing and documenting qualitative 

assessments that licensees can use to 

develop written evaluations to address 

the criteria in NRC’s regulations for 

digital instrumentation and control 

(I&C) modifications. This clarification is 

intended to reduce regulatory 

uncertainty for licensees applying the 

process set in the NRC’s regulations and 

making digital I&C modifications 

without prior NRC approval. 

DATES: The RIS 2002–22, Supplement 1 

is available as of June 25, 2018.

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

Register to comply with publication 

requirements under 1 CFR chapter I.

SUPPLEMENTARY INFORMATION: The Coast 

Guard will enforce Seattle Seafair 

Unlimited Hydroplane Race special 

local regulations in 33 CFR 100.1301 

from 8 a.m. on July 31, 2018, through 8 

p.m. on August 6, 2018. 

Under the provisions of 33 CFR 

100.1301, the Coast Guard will restrict 

general navigation in the following area: 

All waters of Lake Washington bounded 

by the Interstate 90 (Mercer Island/ 

Lacey V. Murrow) Bridge, the western 

shore of Lake Washington, and the east/ 

west line drawn tangent to Bailey 

Peninsula and along the shoreline of 

Mercer Island. 

The regulated area has been divided 

into two zones. The zones are separated 

by a line perpendicular from the I–90 

Bridge to the northwest corner of the 

East log boom and a line extending from 

the southeast corner of the East log 

boom to the southeast corner of the 

hydroplane race course and then to the 

northerly tip of Ohlers Island in 

Andrews Bay. The western zone is 

designated Zone I, the eastern zone, 

Zone II. (Refer to NOAA Chart 18447). 

The Coast Guard will maintain a 

patrol consisting of Coast Guard vessels, 

assisted by Coast Guard Auxiliary 

vessels, in Zone II. The Coast Guard 

patrol of this area is under the direction 

of the Coast Guard Patrol Commander 

(the ‘‘Patrol Commander’’). The Patrol 

Commander is empowered to control 

the movement of vessels on the 

racecourse and in the adjoining waters 

during the periods this regulation is 

subject to enforcement. The Patrol 

Commander may be assisted by other 

federal, state and local law enforcement 

agencies. 

Only vessels authorized by the Patrol 

Commander may be allowed to enter 

Zone I during the hours this regulation 

is in effect. Vessels in the vicinity of 

Zone I shall maneuver and anchor as 

directed by the Patrol Commander. 

During the times in which the 

regulation is subject to enforcement, the 

following rules shall apply: 

(1) Swimming, wading, or otherwise 

entering the water in Zone I by any 

person is prohibited while hydroplane 

boats are on the racecourse. At other 

times in Zone I, any person entering the 

water from the shoreline shall remain 

west of the swim line, denoted by 

buoys, and any person entering the 

water from the log boom shall remain 

within 10 feet of the log boom. 

(2) Any person swimming or 

otherwise entering the water in Zone II 

shall remain within 10 feet of a vessel. 

(3) Rafting to a log boom will be 

limited to groups of three vessels. 

(4) Up to six vessels may raft together 

in Zone II if none of the vessels are 

secured to a log boom. Only vessels 

authorized by the Patrol Commander, 

other law enforcement agencies or event 

sponsors shall be permitted to tow other 

watercraft or inflatable devices. 

(5) Vessels proceeding in either Zone 

I or Zone II during the hours this 

regulation is in effect shall do so only 

at speeds which will create minimum 

wake, 7 miles per hour or less. This 

maximum speed may be reduced at the 

discretion of the Patrol Commander. 

(6) Upon completion of the daily 

racing activities, all vessels leaving 

either Zone I or Zone II shall proceed at 

speeds of 7 miles per hour or less. The 

maximum speed may be reduced at the 

discretion of the Patrol Commander. 

(7) A succession of sharp, short 

signals by whistle or horn from vessels 

patrolling the areas under the direction 

of the Patrol Commander shall serve as 

signal to stop. Vessels signaled shall 

stop and shall comply with the orders 

of the patrol vessel; failure to do so may 

result in expulsion from the area, 

citation for failure to comply, or both. 

The Captain of the Port may be 

assisted by other federal, state and local 

law enforcement agencies in enforcing 

this regulation. 

This notice of enforcement is issued 

under authority of 33 CFR 100.1301 and 

5 U.S.C. 552(a). If the Captain of the Port 

determines that the regulated area need 

not be enforced for the full duration 

stated in this notice of enforcement, he 

or she may use a Broadcast Notice to 

Mariners to grant general permission to 

enter the regulated area.
