Integrated Human Event Analysis System for Event and Condition 
Assessment Method and Software Tool

AGENCY: Nuclear Regulatory Commission.

ACTION: Public meeting and request for comment.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is requesting

DATES: Submit comments by July 30, 2021. Comments received after this 
date will be considered if it is practical to do so, but the Commission 
is able to ensure consideration only for comments received on or before 
this date. The NRC will hold a public meeting as an online webinar. See 
Section IV Public Meeting, of this document for additional information.

ADDRESSES: You may submit comments by any of the following methods; 
however, the NRC encourages electronic comment submission through the 
Federal Rulemaking website:
     Federal Rulemaking Website: Go to https://www.regulations.gov and search for Docket ID NRC-2021-0089. Address 
questions about Docket IDs in Regulations.gov to Stacy Schumann; 
telephone: 301-415-0624; email: [email protected]. For technical 
questions, contact the individual listed in the FOR FURTHER INFORMATION 
CONTACT section of this document.
     Mail comments to: Office of Administration, Mail Stop:

about the availability of information for this action. You may obtain 
publicly available information related to this action by any of the 
following methods:
     Federal Rulemaking Website: Go to https://www.regulations.gov and search for Docket ID NRC-2021-0089.
     NRC's Agencywide Documents Access and Management System 
(ADAMS): You may obtain publicly available documents online in the 
ADAMS Public Documents collection at https://www.nrc.gov/reading-rm/adams.html. To begin the search, select ``Begin Web-based ADAMS

[[Page 18329]]

415-4737, or by email to [email protected]. The IDHEAS-ECA research 
information letter (RIL) is available in ADAMS under Accession No. 
ML20016A481.
     Attention: The PDR, where you may examine and order copies 
of public documents, is currently closed. You may submit your request 
to the PDR via email at [email protected] or call 1-800-397-4209 or 
301-415-4737, between 8:00 a.m. and 4:00 p.m. (EST), Monday through 
Friday, except Federal holidays.

B. Submitting Comments

    The NRC encourages electronic comment submission through the 
Federal Rulemaking website (https://www.regulations.gov). Please 
include Docket ID NRC-2021-0089 in your comment submission.
    The NRC cautions you not to include identifying or contact 
information that you do not want to be publicly disclosed in your 
comment submission. The NRC will post all comment submissions at 
https://www.regulations.gov as well as enter the comment submissions 
into ADAMS. The NRC does not routinely edit comment submissions to 
remove identifying or contact information.
    If you are requesting or aggregating comments from other persons 
for submission to the NRC, then you should inform those persons not to 
include identifying or contact information that they do not want to be 
publicly disclosed in their comment submission. Your request should 
state that the NRC does not routinely edit comment submissions to 
remove such information before making the comment submissions available 
to the public or entering the comment into ADAMS.

II. Background

    The NRC has developed the IDHEAS-ECA human reliability analysis 
(HRA) method with a plan to replace the SPAR-H HRA method (NUREG/CR-
6883) currently in use for risk-informed applications. The IDHEA-ECA 
method was developed based on the IDHEAS-G methodology, Draft, NUREG-
2198, ``The General Methodology of an Integrated Human Event Analysis 
System (IDHEAS-G)'' (ADAMS Accession No. ML20238B988). IDHEAS-G 
provides all technical components required to develop application-
specific HRA methods. IDHEAS-ECA modifies some of the technical 
components for the event condition assessment of the significance 
determination process. The NRC collects human reliability data to 
support the IDHEAS-ECA development. The data is documented in the 
Integrated Human Event Analysis System for Human Reliability Data 
(IDHEAS-DATA) report, Draft RIL-2021-XX, ``Integrated Human Event 
Analysis System for Human Reliability Data (IDHEAS-DATA)'' (ADAMS 
Accession No. ML20238B982). An important data source to the IDHEAS-DATA 
is the NRC's Scenario Authoring, Characterization, and Debriefing 
Application (SACADA) project, is available in ADAMS under Accession No. 
ML17164A077, that collects operator performance information in 
simulator training. The IDHEAS-G, IDHEAS-DATA, and SACADA are 
foundation of IDHEAS-ECA.

III. Specific Considerations

    IDHEAS-ECA is currently published as a RIL and is planned to be 
published as a NUREG report after addressing the public comments from 
this Federal Register notice. IDHEAS-ECA is an HRA method. The software 
tool (IDHEAS-ECA v1.1) is used to perform the calculations of the 
IDHEAS-ECA method. The NRC developed the IDHEAS-ECA software tool in-
house and has all the rights to distribute the software licenses. The 
software is available for all U.S. citizens, but its availability to 
foreign citizens is decided on a case by case. To obtain a copy of the 
software, send an email to Y. James Chang ([email protected]) on the 
subject line state ``Request for IDHEAS-ECA software license.'' In the 
email include the requestor's name, email address, company, and 
nationality. Once the NRC determines to issue the free software license 
to the requester, the requester will receive an email from Dropbox, 
along with the instruction to download the software.

IV. Public Meeting

    The NRC plans to hold a public meeting during the public comment 
period for this action. A public meeting is planned for April 8, 2021, 
via webinar. The NRC will present information about IDHEAS-G, IDHEAS-
DATA, SACADA, and IDHEAS-ECA method and software tool during the public 
meeting. The information would facilitate having a holistic 
understanding of the IDHEAS-ECA development.
    The public meeting will provide a forum for the NRC staff to 
discuss issues and questions with members of the public. The NRC does 
not intend to provide any responses to comments submitted during the 
public meeting. The public meeting will be noticed on the NRC's public 
meeting website at least 10 calendar days before the meeting. Members 
of the public should monitor the NRC's public meeting website for 
additional information about the public meetings at https://www.nrc.gov/public-involve/public-meetings/index.cfm. The NRC will post 
the notices for the public meetings and webinars and may post 
additional material related to this action to the Federal Rulemaking 
website at https://www.regulations.gov/ under Docket ID NRC-2021-0089.
