[External_Sender] Summary table showing key attributes for eligibility criteria Date: Wednesday, April 21, 2021 12:57:13 PM Attachments: ARPS Rule Eligibility Criteria Attribute Summary Table.docx Importance: High

Nan, Good afternoon.

As discussed during the meeting this morning, the attached table shows our understanding of the key attributes associated with each of the eligibility criteria. I ask that your folks review the table and then let me know if were aligned in our understanding or if adjustments are needed. Given my commitment to get you the guidance in time to support the near-term rulemaking schedule milestones, I request a timely review and return of staff feedback. Any method of providing the feedback is fine with me - telephone call, email or meeting.

A target set is the minimum combination of equipment or operator actions which, if all are prevented from performing their intended safety function or prevented from being accomplished, would result in offsite doses greater than the reference values in §§ 50.34(a)(1)(ii)(D) and 52.79(a)(1)(vi).

An achievable target set means a target set that is within the ability of the DBT to compromise, destroy, or render nonfunctional, absent actions by an onsite armed response force.
